Overclocking Dial-UP

How many times have you had to remember obscene epithets about your Internet connection? The usual thing. However, when it comes to online games (in particular their Internet implementations), latency-sensitive game traffic sometimes becomes the straw that overflows the cup of patience, and we begin to seriously think about an expensive “dedicated line”. However, with skillful configuration, even the latest noname modem can be comparable in speed to expensive “external” modems with excellent reception/transmission characteristics.

What is in our power is to ensure high-quality wiring from the modem to the panel. And this is very important, because even small interference or “unreasonable” resistance can significantly reduce the speed Internet connections due to the appearance of erroneous packets, the correction of which will require additional overhead. As a cable subsystem (we will express it in terms of SCS - structured cabling system), it is recommended to use “twisted pair” - UTP category 5, unshielded. Shielded twisted pair is not usually used for telephone wiring, but if you have no choice, it must be grounded. It should be recalled that any physical impact on the cable may lead to a change in its characteristics. Therefore, it is necessary to lay the line under the baseboard or in boxes, avoiding strong bends.

Wiring in the apartment must be carried out in accordance with the drawing. The main thing to take away from the diagram is that phone line must be connected directly to the modem. All telephone sets are connected to the line via a modem, and now the Internet will have the highest priority compared to “talk devices”. But this is not the most important thing. Our task is to eliminate any additional resistance that telephone sets create. All cable joints, the number of which should be minimal, must be soldered.

To avoid interference and interference, the cable should be laid no closer than 50 cm to the power lines if they run parallel. When they intersect at right angles, then this is permissible. It is also advisable to ground the system unit.

Provider, respond!

Now we have the “ideal” cable system and we need to move on to choosing a provider. This is probably one of the key points Internet optimization. When a provider administers its own game server, then when connecting to it, it doesn’t matter to us what channel it has with the “outside world”. In another situation, and this is the most common, this is almost the most critical parameter. Of course, it must be taken into account along with the number of users connecting to the provider and sharing the Internet bandwidth among themselves. Information about providers can be viewed, for example, on the website www.provider.net.ru.

As mentioned above, gaming traffic is very sensitive to delays. For example, a familiar situation when you load some Quake 3 Arena, find like-minded people (gamers like you) and cannot even hit the enemy from two meters due to the fact that until the information about your shot reaches the “enemy”, he will have time to escape. In this regard, when choosing a provider, you need to pay attention to such a parameter as MTU (Maximum Transmission Unit). This is the maximum block of data that is transmitted over the network and a packet larger than the provider's MTU will be fragmented, which will take more time to deliver useful information, and that is provided that the provider allows fragmentation of IP packets (it should be noted that, as a rule, , it is allowed). Current providers use switching equipment that is capable of independently adjusting the MTU size according to a given algorithm, which is adaptive. Therefore, it turns out that only the user can set a hard MTU. By the way, the user usually also has dynamic MTU selection enabled by default, but we will set it manually.

As for choosing a provider, which is not entirely related to optimization, but rather simply to the possibility of reliable operation on the Internet, you need to pay attention to the status of the company, how many corporate buyers use its services, whether there are backup servers (mail, DNS, etc.) , what equipment is installed and how wide the modem pool is. In general, all of this determines how stably and quickly your Internet requests will be processed.

OS internals.

“Shura, launch Berlaga” (O.I. Bender)

It's time to climb into the holy of holies of the OS - the system registry - and configure local Internet settings. Parameters may be great amount , especially if we take into account the tasks for which the application level is implemented independently, and not by OS means. But we will consider the most basic parameters and those that can significantly affect online games and Internet speed. In Windows XP, developers tried to take into account such an important area of modern networks as ensuring quality of service (QoS - Quality Of Service). The fact is that Internet channels are sometimes overcrowded, and delay-sensitive traffic (for example, voice or video) must be given higher priority than regular data. This is exactly what QoS technology does. The developers of Windows XP began to reserve 20% of the Internet channel bandwidth to ensure proper quality of service (implementation of QoS RSVP - resource reservation protocol). By the way, it is worth saying that QoS protocols do not work well on the Internet yet, and they are unlikely to be used in the foreseeable future, at least in RuNet. Nowadays, in many teleconferences there is a myth that 20% of the bandwidth is reserved in any case and the percentage should be reduced to 0 or QoS should be completely disabled. An article was published on the Microsoft website indicating that quality of service protocols only work with applications where this is implemented in software (the QoS API was used during development). We can say with complete confidence that we will not find such applications on a home computer, because the development of such software products is just becoming widespread, and these projects are mainly aimed at supporting IP telephony or expensive distributed ERP systems (or enterprise resource management systems ), such as, for example, SAP R/3. If you do not want QoS RSVP to work on your PC, you can set the reserved bandwidth to 0% or disable this service altogether. Type gpedit.msc on the command line, go to Computer Configuration – Administrative Templates – Network – QoS Packet Manager, select Limit reserved bandwidth. Double-clicking will bring up a window where you need to enable quality of service and limit bandwidth to 0%. Next, you should make sure that the QoS protocol is enabled. To do this, right-click on Network Places, then Properties, go to the Internet connection properties, Network tab and find QoS Packet Scheduler there. If the protocol is not there, then it needs to be installed. After performing these operations, restart your computer. If you want to disable the service, go to Start > Settings > Control Panel > Administrative Tools > Services >

Now let's talk about the previously mentioned maximum data unit (MTU). The maximum packet in our switched networks is usually a block of data of 1500 bytes. When using the Internet for games, you need to keep the MTU small. The fact is that the larger the packages, the more time and overhead it will take to deliver them, and gaming traffic cannot afford such a luxury. Therefore, setting an MTU of 1500 bytes is excluded. On the other hand, if this parameter is too small, then a minimum of “useful” information will be transmitted, and a maximum of service data in the form of protocol headers and clock signals. This is also an extreme that should be avoided. The Internet MTU (when PPP is running) of 576 bytes is often called the de facto standard. Therefore, we will not be the first to suggest using this particular figure for games. To do this, run regedit.exe and look for the following registry branch - HKEY_LOCAL_MACHINE\ System\ CurrentControlSet\Services\Tcpip\Parameters\Interfaces\[Adapter ID]. There may be several adapters, and not all of them are real. We create an MTU dword parameter for each and specify a value equal to 576 in the decimal number system. There is also a parameter MSS – Maximum Segment Size. This is the size of the data segment, which, together with the protocol headers, constitutes the MTU. The size of the headers is fixed and in general is 40 bytes. Therefore, it is not necessary to set the MSS size, because with MTU=576 bytes, MSS is 536 bytes. If you still want to set the MSS value manually, then create an MSS key in the same registry branch.

There is an algorithm by which two nodes can choose the MTU value themselves after exchanging their MSS values. This method is called Path Maximum Transmission Unit Discovery - The maximum size of the transmitted packet for this path. To enable it, create the EnablePMTUDiscovery key in the registry branch HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters and assign it the value “1”; if we disable this algorithm, then assign it “0”. The PMTU Discovery method has an extension that allows you to identify those routers that do not notify the host about the loss of packets if this occurs because they cannot be fragmented (these routers are considered stub routers and are not used in the future). T.N. The Black Hole Detect algorithm is enabled by creating the EnablePMTUBHDetect key with the value “1” in the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters branch. It is advisable to turn off both of these methods, because their operation can significantly slow down the process of messaging on the network.

The next important parameter is the so-called “sliding window”. Let's define the terms. We will call a “sliding window” a certain data buffer that is located at the receiving station and is filled by the source station with packets, confirmation of receipt of which can be sent by the receiving station at any time, but no later than the data buffer overflows. Thus, packets sent by the source when the receiver window is full will be discarded. In connection with the above, we determine that it is advisable to increase the window size for reliable lines, and decrease it for bad ones. Again, the de facto standard for the PPP protocol (by which we work at the data link level on the Internet) is a window size of 4288 bytes. If you have more or less reliable communication lines with the provider, then the specified size can be increased, but remembering that the window size must be a multiple of MSS (for example, 5360 or 8040). This is done to ensure that the window buffer is filled only with useful data and is not reserved for smaller packets that it is not capable of receiving. We look at the registry branch HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters - the TcpWindowSize parameter (if not, create it manually). If you have a “super-ideal” Internet channel and want to increase the “sliding window” to 64 KB or more, then in the registry you need to create a dword key “Tcp1323Opts” with the value “1” at the address HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Services\Tcpip \Parameters.

The TTL (Time To Live) value indicates the period of time during which a certain packet (or, for example, a route), which the local PC knows about, will “live”. Those. Until this time expires, the computer will think that the packet it sent has not yet reached its destination, although it may have simply been discarded by the recipient, for example due to a buffer overflow. This is where the opportunity to increase speed is hidden. The fact is that by default this value is large and needs to be reduced. On the other hand, if it is too small, then all packets will be considered lost and will be sent again and again. This obviously will not increase the speed of your channel. Therefore, the TTL value must be changed and selected to suit your needs, balancing between two extremes. It is recommended to set the DefaultTTL key value to 128 in the HKEY_LOCAL_MACHINE\ System\ CurrentControlSet\Services\Tcpip\Parameters registry key. By default, it is assigned 255, which is clearly an overestimated number. Windows 2000/XP systems have the ability to selectively transfer corrupted data. That is, if several packets are transmitted in a row and one of them does not reach the recipient, then the sender resends only the damaged packet, and not the entire series of packets. This, of course, also affects the speed, therefore, to enable this algorithm, we create the dword key “SackOpts” with the value “1” in the registry at the address HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters.

There is one more parameter that is not used on NT systems, but many gamers are on 9x/Me, so it should be mentioned. NDI Cache (Network Device Interface - network device cache) - used by the operating system to store packet routing information. The default is 0. And you can change it in the registry branch HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\NWLink\Ndi\param

s\cachesize. It is necessary to change the Default key to the desired value (16 is recommended). In addition to what has been described for optimizing your Internet connection manually, there are many programs that can automate this process. However, there are now a huge number of them, and you shouldn’t trust them all blindly. Because they can “optimize” your Internet connection in such a way that the Network will easily disappear or will work at such a speed that it will only satisfy ICQ users, and even then not to the fullest. And web surfing or, God forbid, the use of ftp archives will become impossible. Therefore, after analyzing a large number of programs, it is recommended to use Modem Booster first. The program is suitable for both “knowledgeable” users and those who do not have the slightest idea about the operation of protocols, but are also eager to improve the performance of the Network. You can download it, for example, from the site http://news.proext.com. It works in two modes - either you manually set the values of key network parameters, or you press only one “Start” button and your Internet connection will be optimized automatically within 2-3 hours. It is suitable for almost all operating rooms

Windows systems – from 98 to XP.

The Internet Tweak utility has greater flexibility. It also supports all Windows operating systems and has over 180 customizable settings. It is possible to change the settings of popular browsers (Internet Explorer, Netscape Communicator), email clients, and also optimize hidden operating system options. You can download it at http://www.magellass.com/files/inttweak.exe. The utility is shareware.

Named Moped.

"Now it will take place

removal of the body of the deceased" (O.I. Bender)

Looking at the last epigraph, I wanted to advise the reader to throw away (the same as give away) his good old Winmodem and buy some Zyxel (Russian - “zuhel”). Moreover, as we understand, the more expensive Zyxel is, the better and faster our connection to the Internet will be. Of course, looking into our wallet, where we’ve already put aside an honest ten piece (or something like that) for a new issue of Upgrade Special, we immediately discard this seditious thought, and, rolling up our sleeves, we try to squeeze the maximum out of our “peasant horse”. First, you need to make sure you have the latest driver installed. The fact is that almost all levels of the network model in winmodems are implemented in software, and the speed and some other communication parameters directly depend on the software.

Now let's get into the settings of your engineering miracle. Start > Settings > Control Panel > Phone and Modem, then select the Modems tab, where we see the installed modem. We go to Properties and here we again see the Modem tab. Set the Port Speed parameter for the modem to 115200 (or higher, if your modem is capable of higher speeds). What is set here is not the speed of the connection between the modem and the provider, but the speed between the virtual port of the computer and the modem to which it is connected. That. this value should be the maximum, however, on older devices with low speeds (33600 and below), setting this port speed may cause errors.

On the Diagnostics tab, you must disable Logging. This will additionally load the processor and additional downtime may occur. In the Additional communication parameters tab, you need

set the region to Russia, although some modems can only work if the country is set to USA. The Additional parameters... button takes you to the settings of FIFO receive/transmit buffers (not to be confused with the “sliding window”). The size of these buffers should be as large as possible if we want to achieve greater speed. The Change Defaults... button hides the settings shown in the figure below. It is recommended to set everything as shown in the screenshot. At least as far as the data line connection parameters are concerned. It is important that compression is enabled, and hardware flow control is enabled, requiring minimal system resources.

We leave additional communication parameters unchanged. The function of manually initializing the modem string may also be interesting. To do this, you need to close the last customizable window and return to the previous one. At the top we see a line called “Additional initialization commands”. Now let's figure out what it is. Each modem has a protocol that it uses, as well as commands that it supports. These commands are used to control the modem using the operating system. And the speed of the device will depend on how it is initialized, and by and large, not only that. As for the line itself, it is impossible to give any general advice. For each modem you need to select your own line, and in this case you need to surf the Internet and look for documentation on the modem. By the way, if your device can be reflashed, then the exit latest versions Firmware must also be monitored. This is done using a special firmware program for a specific device model and, of course, the binary code itself, written as a file. There is also the so-called Rollback firmware so that you can return everything to its previous state if problems arise. For many modems, there are special configuration programs. For example, for modems on a Rockwell chip, software can be found at http://www.rampitec.spb.ru/modem.htm.

Well, the last thing I want to say about setting up the modem, or rather again implementing the application level, is the protocols used. For the channel you must use PPP, for everything else the TCP/IP protocol stack. IP header compression must be enabled, the DNS server (primary and backup) must be specified, and WINS and NetBIOS must be disabled if it is in the settings. All this is done in the Start menu > Settings > Control Panel > Network Connections, then Properties of the selected connection and the Network tab.

What about Quake and Co.?

Now let's talk about the very games that cause us to quarrel with our family, fast (excluding chips, crackers, seeds and beer), ignore study/work and develop a passion for weapons, mass murder, profanity - in general, for everything beautiful.

By default, we consider Counter Strike (Half Life) and Quake to be the most popular 3D shooters of all time. It’s for them that we’ll look at optimizing the Internet connection.

Thanks to the popularity of these games and the great interest in them among the progressive half of humanity, special programs are beginning to appear to optimize the dial-up connection when playing with Internet colleagues. For CS you can download AntiPing (a bit of an incorrect name, AntiLag would be more correct) at http://money-home.narod.ru/antiping.rar. This is a configuration file that needs to be copied to the directory where the game is installed, and the corresponding command must be entered in the console (the description in Russian is in the same archive). Detailed description console commands and new improvements in the latest CS patch can be viewed on the website http://counter-sport.by.ru/netgame/netgame.shtml. There are also all the cheat codes and tips for optimizing the Internet game.

Many utilities have also been released for Quake 3 Arena to improve performance (and not just Internet connections). The most popular program today is Q3A – Total Control v0.6. You can download it at http://planetquake.com/borderfield. During installation, the program itself finds the installed version of Quake 3 Arena. Next, we launch the utility and in the Tools > Dial-Up Optimizer menu we see the window shown in the screenshot.

As you can see, there are all the parameters described by us, and the value of which was supposed to be changed manually.

And finally...

As you can see, there are many ways and approaches to optimizing the Internet connection for playing online. This includes the use of special programs that manually or automatically set the required values for the “communication” parameters, and alteration of the registry to suit your operating system and the Internet channel using the regedit.exe utility, and changing only two or three main registry keys, which will give a noticeable increase in data transfer speed. In any case, initiative should be rewarded. Therefore, do not be afraid to experiment, especially if the registry was exported on time. Well, as one famous movie character used to say - “may the Force be with you”!

Optimizing your Internet connection

How many times have you cursed your slow dial-up and started saving money for a dedicated line! Meanwhile, with skillful configuration, even the latest noname modem can compare in speed with expensive external models. It is recommended to optimize your Internet connection in several stages. We will start, of course, with the physical connection medium (FSS), or simply with the cable wiring.

The wiring from the modem to the panel simply must be of high quality. Even slight interference or unreasonable resistance can significantly reduce the speed of your Internet connection. The reason is the appearance of erroneous packets, the correction of which will require additional overhead.

As a cable subsystem, it is recommended to use unshielded twisted pair - UTP category 5. Shielded twisted pair cables are not usually used for telephone wiring, but if you have no choice, be sure to ground them. It should be recalled that any physical impact on the cable may lead to a change in its characteristics. Therefore, it is necessary to lay the line under the baseboard or in boxes, avoiding strong bends.

Wiring in the apartment should be carried out in accordance with the drawing. All telephones are connected to the line via a modem, and now the Internet has priority over “talk devices”. But this is not the most important thing. Our task is to eliminate any additional resistance that telephone sets create. All cable joints, the number of which should be minimal, must be soldered.

To avoid interference and interference, the cable should be laid no closer than 0.5 m to the power lines if they run parallel (intersection at right angles is acceptable). It is also advisable to ground the system unit.

PROVIDER, RESPOND!

Now that we have the ideal cable system, we can move on to choosing a provider. This is perhaps one of the key points in optimizing your Internet connection. If you use a game server from your own provider, then it does not matter what the width of its communication channel with the “outside world” is. Otherwise, this is perhaps the most critical parameter. Of course, it must be taken into account along with the number of users connecting to the provider and sharing the Internet bandwidth among themselves. Information about providers can be found, for example, on the website www.provider.net.ru.

Gaming traffic is very latency sensitive. Many people are familiar with this situation: you load some Quake 3 Arena, find like-minded people and... you can’t hit the enemy from two meters, because while the information about your shot reaches the “enemy”, he manages to hide. In this regard, when choosing a provider, you need to pay attention to such a parameter as MTU (Maximum Transmission Unit) - the maximum block of data that is transmitted over the network.

A packet larger than the provider's MTU will be fragmented (as a rule, such fragmentation is allowed), which means it will take longer to deliver useful information. Current providers use switching equipment that is capable of independently adjusting the MTU size according to a given algorithm, which is adaptive. Therefore, it turns out that only the user can set a rigid MTU. Usually the user has dynamic MTU selection enabled by default, but we will set it manually.

When choosing a provider, you also need to pay attention to the status of the company, the number corporate clients, availability of backup servers (mail, DNS and others), equipment and modem pool. This determines how stably and quickly your Internet requests will be processed.

OS INTERNALS

It's time to get into the holy of holies of the OS - the system registry - and configure local Internet settings. There can be a huge number of parameters, especially if you take into account tasks for which the application level is implemented independently, and not using OS tools. But we will look at those that can significantly affect online gaming and connection speed.

QoS technology

In Windows XP, developers tried to take into account such an important area of modern networks as ensuring quality of service (QoS - Quality Of Service). The point is that delay-sensitive traffic (for example, voice or video) must take priority over regular data. This is exactly what QoS technology does.

Windows XP developers began to reserve 20% of the Internet channel bandwidth to ensure proper quality of service (implementation of QoS RSVP - resource reservation protocol). By the way, it is worth saying that QoS protocols do not yet work well on the Internet and are unlikely to be used in the foreseeable future, at least in the RuNet.

An article was published on the Microsoft website indicating that quality of service protocols only work with applications that were developed using the QoS API. We will not find such applications on a home computer, since they are designed mainly to support IP telephony or expensive distributed ERP systems (enterprise resource management systems), such as, for example, SAP R/3. If you still do not want the QoS RSVP protocol to work on your PC, you can set the reserved bandwidth to 0% or disable this service altogether.

Type gpedit.msc in the command line, then in “Computer Configuration” > “Administrative Templates” > “Network” > “QoS Packet Manager” select “Limit reserved bandwidth”. Double-clicking will bring up a window where you need to enable quality of service and limit bandwidth to 0%.

Next, make sure that the QoS protocol is enabled: “Network Neighborhood” > Right Click > “Properties” > “Internet Connection Properties” > “Network” > “QoS Packet Scheduler”. If the protocol is not there, then it needs to be installed. After completing these operations, restart your computer. If you want to disable the service, go to “Start” > “Settings” > “Control Panel” > “Administration” > “Services” > QoS RSVP and in the properties set the startup type to “Disabled”.

Let's first go back to MTU. The maximum packet in our switched networks is usually a 1.5 kB data block. When using the Internet for gaming, it is better to keep the MTU small. As already mentioned, the larger the packages, the longer it will take to deliver them, and gaming traffic cannot afford such a luxury.

Therefore, setting an MTU of 1.5 kB is excluded. On the other hand, if this parameter is too small, then a minimum of useful information will be transmitted, and a maximum of service data in the form of protocol headers and clock signals. This is also an extreme that should be avoided. The optimal and actually standard MTU value for the Internet (when the PPP protocol is running) is 576 bytes.

To set this value, run regedit.exe and look for the following registry branch - HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\[Adapter ID]. There may be several adapters, and not all of them will be real. For each, we create a dword parameter MTU and specify a value equal to 576 in the decimal number system. There is also a parameter MSS – Maximum Segment Size. This is the size of the data segment, which, together with the protocol headers, constitutes the MTU.

The header size is fixed and is generally 40 bytes. Therefore, it is not necessary to set the MSS size: with an MTU of 576 bytes, the MSS is 536 bytes. But if you still want to set the MSS value manually, create an MSS key in the same registry branch.

There is an algorithm by which two nodes can choose the MTU value themselves after exchanging their MSS values. This method is called Path Maximum Transmission Unit Discovery (PMTU Discovery). To enable it, create the EnablePMTUDiscovery key in the registry branch HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters and assign it the value “1″ (if this algorithm is disabled, “0″).

The PMTU Discovery method has an extension that allows you to identify those routers that do not notify the host of packet loss if this occurs because they cannot be fragmented (these routers are considered stub routers and are not used in the future). The so-called “black hole detection” algorithm (Black Hole Detect) is enabled by creating the EnablePMTUBHDetect key with the value “1″ in the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters branch. It is advisable to disable both of these algorithms, since their operation can significantly slow down the process of messaging on the network.

The next important parameter is the so-called “sliding window”. This is a kind of data buffer that is located at the receiving station and is filled with packets by the source station. Confirmation of their receipt is sent by the receiving station at any time, but no later than the data buffer overflows. Thus, packets sent by the source when the sink window is full will be discarded. This means that it is advisable to increase the window size for reliable lines, and decrease it for bad ones.

The de facto standard for the PPP protocol (by which we work at the link level on the Internet) is a window size of 4.288 kB. If your communication lines with the provider are reliable enough, then the specified size can be increased, but do not forget that the window size must be a multiple of the MSS (for example, 5.36 KB or 8.04 KB). This is done to ensure that the window buffer is filled only with useful data and is not reserved for smaller packets that it is not capable of receiving.

We look at the registry branch HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters - the TcpWindowSize parameter (if not, create it manually). If you have an ideal Internet channel and want to increase the “sliding window” to 64 kb or more, then in the registry you need to create a dword key “Tcp1323Opts” with the value “1” at the address HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters.

The TTL (Time To Live) value indicates the period of time during which a certain packet (or, for example, a route), which the local PC knows about, will “live”. In other words, until this time expires, the computer will think that the packet it sent has not yet reached its destination (although it could simply be discarded by the recipient, for example, due to a buffer overflow). This is where the opportunity to increase speed is hidden. On the one hand, the default value is too high.

On the other hand, if it is too small, all packets will be considered lost and will be sent again and again. This obviously will not increase the speed of your channel. Therefore, when choosing the TTL value, you need to balance between two extremes. It is recommended to set the DefaultTTL key value to 128 in the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters registry branch (by default it is assigned a clearly inflated value of 255).

Windows 2000/XP systems have the ability to selectively transmit damaged data: if several packets are transmitted in a row and one of them does not reach the recipient, then the sender resends only the damaged packet, and not the entire series of packets. This, of course, also affects the speed, therefore, to enable this algorithm, we create a dword key “SackOpts” with the value “1” in the registry at the address HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters.

There is one more parameter that is not used in NT systems, but still deserves mention, since many gamers “sit” on 9x/Me. NDI Cache (Network Device Interface - network device cache) is used by the operating system to store packet routing information. By default, its value is 0. If necessary, in the registry branch HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\NWLink\Ndi\params\cachesize the Default key can be assigned the desired value (16 is recommended).

Automatic optimization

You can optimize your Internet connection not only manually, but also automatically, using special programs. There are a huge number of them now, but you shouldn’t trust them all blindly. Some of them can disrupt your Internet connection in such a way that the Network will easily disappear or will work at a speed that is not capable of satisfying even ICQ users.

We recommend paying attention to the Modem Booster program. It is suitable for both knowledgeable users and those who do not have the slightest idea about how protocols work, but still want to improve the performance of the Network. You can download it, for example, from the website news.proext.com. It works in two modes - either you manually set the values of key network parameters, or you press only one “Start” button and your Internet connection is automatically optimized within 2-3 hours. It is suitable for almost all Windows operating systems - from 98 to XP.

The Internet Tweak utility has greater flexibility. It also supports all Windows operating systems and has over 180 customizable settings. The user gets the opportunity to change the settings of popular browsers (Internet Explorer, Netscape Communicator), email clients, and also optimize hidden OS options. You can download this shareware utility at www.magellass.com/files/inttweak.exe.

EDUCATION OF THE MODEM

Now let's get down to the good old Winmodem and try to squeeze maximum speed out of it.

First, you need to make sure that you have the latest driver installed. The fact is that almost all levels of the network model in “winmodems” are implemented in software, and the speed and some other communication parameters directly depend on the software.

Let's go into the settings of this miracle of engineering: “Start” > “Settings” > “Control Panel” > “Phone and Modem” > “Modems”. We see the installed modem, go to “Properties” and here again we see the “Modem” tab. We set the “Modem port speed” parameter to 115,200 bps (or higher - if, of course, your modem is capable of this).

What is set here is not the connection speed between the modem and the provider, but the speed of data exchange between the virtual port of the computer and the modem to which it is connected, and its value should be maximum. However, it should be noted that on older devices with disabilities(33,600 bps and below), setting this port speed may cause errors.

cFosSpeed is a network driver that binds to existing Internet connections and optimizes data transfer by prioritizing traffic. Traffic prioritization is a method of optimizing Internet traffic that provides maximum speed with minimal delays. You can use cFosSpeed with a router and/or DSL modem or with cable modem. It can also be used with other types of Internet connections. cFosSpeed supports big choice connections such as DSL, cable, ISDN, UMTS and others. The program will help keep network latency (ping) low to make Internet applications as responsive as possible. Also, one of the main goals of cFosSpeed is to improve throughput by eliminating network congestion. The program interface has been translated into many languages, including Russian.

System requirements:
Windows 7 | 8 | 8.1 | 10

Surely, every user has repeatedly experienced a feeling of discomfort at moments, for example, while watching a favorite movie on the Internet, when video playback suddenly stops and a buffering phenomenon is observed.

Freezing of an open page, an unusually long loading time for a site, a loss of connection - all these are unpleasant consequences of the “congestion” that occurs along the way of transmitting information packets over the network.

Regardless of the type of connection, the methods that will be described here will, to one degree or another, increase the Internet speed on Windows 7, this article will be especially useful for mobile Internet users.

How to remove Internet speed limit?

Method 1: Settings in the serial port parameters (COM1)

So, in order for us to detect these parameters, we go to the device manager (an Internet connection is not required now, the modem can be completely disabled): Start menu - Computer.

In Device Manager, open the “Ports” item.

Here we select “Serial Port (COM1)”.

Next in the window: Port parameters - in the “Bits per second” column, set the maximum value, confirm by clicking “Ok” and close all tabs.

Method 2: Settings in Reserved Bandwidth Limit Settings

Let's start searching for parameters: Start menu - All programs - Accessories - Command line

In the command line, enter the command: gpedit .msc and press the Enter key.

In the menu that opens, look for the “Computer Configuration” item and open it.

Then open the following folders: Administrative Templates - Network - Qos Packet Scheduler - Limit Reserved Bandwidth

In the window that appears, place a marker next to the “Enable” item, and below in the “Bandwidth limit (%):” column enter the value - 0.

How to improve Internet speed using software?

Method 3: increase Internet speed using the Auslogics BoostSpeed utility

For this method you need to download and install the Auslogics BoostSpeed program. This utility is available on the Internet as a free version, so don’t feed scammers! The program weighs only about 7 MB, we install it by default on the local drive C.

After installing the program, reboot the system manually for the settings to take effect. Before using the utility, connect to the Internet and go into it through the shortcut that appears on the desktop.

Here we are interested in the “Tools” section. By clicking on it in the new menu we find the item “Internet acceleration”.

Below it, click on the “Automatic” button, select from three possible requests for Internet speed: fast, medium or slow, in accordance with your type of network connection, by moving the marker, we start the process through the “Analysis” button.

After checking, a list of all parameters that require optimization will appear on the screen, so click “Optimize” and wait for the operation to complete.

After which, a window will appear with a report on the work done and below the “Reboot” button.

Click on it, thereby rebooting Windows to accept the new data.

What to do if the Internet speed has dropped sharply?

Method 4: Delete temporary files from Application Data

In Application Data (AppData folder), we need only one directory called “Temp“. But to get to it, we need to first discover AppData, because it is a hidden system file.

To do this, perform the following algorithm of actions: Start menu - Computer - Organize (the button at the top of the window, on the left) - Folder and search options

Next is the view - in the window with additional parameters, go down the list, find the item “Show hidden files, folders and drives”, place a marker opposite it - a little higher in the list we find the column “Hide protected system files (recommended)” and uncheck the option - in the warning window, put consent - “Yes” - click in the previous window with the folder parameters “Apply”.

Thus, we removed the protective effect of invisibility from hidden system files; some of them will be found on the desktop.

Having found this folder, right-click on the name, find “Send” in the menu and click on “Desktop (create shortcut)”.

After all the steps, you can hide system files again in reverse order through the folder options. In this case, the folder “Temp” we need on the desktop will remain visible.

So, why do we need the Temp folder? When you launch the browser, as well as when visiting various pages, blogs, and sites, some temporary files from the network are delayed in the desired folder, which in turn slows down data transfer. Therefore, if we notice a clear slowdown in page loading or a sharp drop in Internet speed, we should minimize the browser without closing it and enter the “Temp” folder.

In the “Temp” folder, select all the data and delete it using the Delete key or the right mouse button. Those files that are not deleted are service files; the rest of the “garbage” will end up in the trash, which should be emptied immediately.

I love simple “one-click” computer programs, especially if they are in Russian, free and do everything that users expect from them.

Today I want to talk about a similar program for optimizing the Internet.

Auslogics Internet Optimizer will automatically check your system and browser Internet connection settings and optimize them with one click of the computer mouse (the program also has a manual mode for advanced users).

This program was once a stand-alone program a long time ago, but is now part of the Auslogics BoostSpeed optimization package. This is an excellent set of programs for speeding up your computer, but it’s a little expensive and a bit big.

Although Auslogics Internet Optimizer is included in the free trial version of Auslogics BoostSpeed, I still suggest temporarily installing a clean version of the Internet optimizer, improving your network settings with one click, and then uninstalling it.

This way you will do without unnecessary programs (running services) on your computer and get faster loading of sites.

Attention! Auslogics Internet Optimizer will not expand your Internet channel given by the provider, but will change the network settings to display sites faster, which is what Internet optimization will achieve.

Many people will find the above explanation complicated, so the best way to understand it, install the program and see how the Internet speeds up in practice.

Download Auslogics Internet Optimizer

So, there is no longer a separate program on the manufacturers’ official website - I suggest downloading it from the link below, from Yandex.Disk...

Don't worry - this is a completely free and working utility...

Don’t click “Update” - it will redirect you to the website and offer to download the full Auslogics BoostSpeed package and nothing more.

How to use an Internet accelerator

After launching Auslogics Internet Optimizer will ask about the type of your Internet connection...

Point and click on “Analysis”...

We get the result...

When you hover your mouse over a line, a hint will appear at the bottom of the program window...

CLOSE ALL BROWSERS and click “Optimize”...

That's all Internet optimization is - we launch the browser and enjoy the boiling water from fast surfing the Internet.

If you have advanced knowledge of Internet connection settings, you can use manual mode program work...

USEFUL VIDEO

PROVIDER, RESPOND!
Now that we have the ideal cable system, we can move on to choosing a provider. This is perhaps one of the key points in optimizing your Internet connection. If you use a game server from your own provider, then it does not matter what the width of its communication channel with the “outside world” is. Otherwise, this is perhaps the most critical parameter. Of course, it must be taken into account along with the number of users connecting to the provider and sharing the Internet bandwidth among themselves. Information about providers can be found, for example, on the website www.provider.net.ru.

When choosing a provider, you also need to pay attention to the status of the company, the number of corporate clients, the availability of backup servers (mail, DNS and others), equipment and modem pool. This determines how stably and quickly your Internet requests will be processed.

OS INTERNALS
It's time to get into the holy of holies of the OS - the system registry - and configure local Internet settings. There can be a huge number of parameters, especially if you take into account tasks for which the application level is implemented independently, and not using OS tools. But we will look at those that can significantly affect online gaming and connection speed.

QoS technology
In Windows XP, developers tried to take into account such an important area of modern networks as ensuring quality of service (QoS - Quality Of Service). The point is that delay-sensitive traffic (for example, voice or video) must take priority over regular data. This is exactly what QoS technology does.

Next, make sure that the QoS protocol is enabled: “Network Neighborhood” > Right Click > “Properties > “Internet Connection Properties” > “Network” > “QoS Packet Scheduler”. If the protocol is not there, then it needs to be installed. After completing these operations, restart your computer. If you want to disable the service, go to “Start” > “Settings” > “Control Panel” > “Administration” > “Services” > QoS RSVP and in the properties set the startup type to “Disabled”.

There is an algorithm by which two nodes can choose the MTU value themselves after exchanging their MSS values. This method is called Path Maximum Transmission Unit Discovery (PMTU Discovery, “detecting the maximum size of a transmitted packet for a given path”). To enable it, create the EnablePMTUDiscovery key in the registry branch HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters and assign it the value “1” (if this algorithm is disabled, “0”).

The PMTU Discovery method has an extension that allows you to identify those routers that do not notify the host of packet loss if this occurs because they cannot be fragmented (these routers are considered stub routers and are not used in the future). The so-called “black hole detection” algorithm (Black Hole Detect) is enabled by creating the EnablePMTUBHDetect key with the value “1” in the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters branch. It is advisable to disable both of these algorithms, since their operation can significantly slow down the process of messaging on the network.

Windows 2000/XP systems have the ability to selectively transmit damaged data: if several packets are transmitted in a row and one of them does not reach the recipient, then the sender resends only the damaged packet, and not the entire series of packets. This, of course, also affects the speed, therefore, to enable this algorithm, we create a dword key “SackOpts” with the value “1” in the registry at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters.

There is one more parameter that is not used on NT systems, but still deserves mention, since many gamers “sit” on 9x/Me. NDI Cache (Network Device Interface - network device cache) is used by the operating system to store packet routing information. By default, its value is 0. If necessary, in the registry branch HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\NWLink\Ndi\params\cachesize the Default key can be assigned the desired value (16 is recommended).

Automatic optimization
You can optimize your Internet connection not only manually, but also automatically, using special programs. There are a huge number of them now, but you shouldn’t trust them all blindly. Some of them can disrupt your Internet connection in such a way that the Network will easily disappear or will work at a speed that is not capable of satisfying even ICQ users.

EDUCATION OF THE MODEM
Now let’s get down to the good old “Winmodem” and try to squeeze maximum speed out of it.
First, you need to make sure that you have the latest driver installed. The fact is that almost all levels of the network model in “winmodems” are implemented in software, and the speed and some other communication parameters directly depend on the software.

Let’s get into the settings of this miracle of engineering: “Start” > “Settings” > “Control Panel” > “Phone and modem” > “Modems”. We see the installed modem, go to “Properties” and here again we see the “Modem” tab. We set the “Modem port speed” parameter to 115,200 bps (or higher - if, of course, your modem is capable of this).

What is set here is not the connection speed between the modem and the provider, but the speed of data exchange between the virtual port of the computer and the modem to which it is connected, and its value should be maximum. However, it should be noted that on older devices with limited capabilities (33,600 bps and below), setting this port speed may cause errors.

On the “Diagnostics” tab, you need to disable “Logging” - this will relieve the processor from additional load. In the “Advanced communication settings” tab, you need to set the region to “Russia” (at the same time, some modems can only work if you select “USA”). The “Advanced parameters...” button takes you to the settings of FIFO receive/transmit buffers (not to be confused with the “sliding window”).

If we want to achieve greater speed, the size of these buffers should be maximum.
The “Change defaults...” button hides the settings shown in the figure. It is advisable to use it as a sample - first of all, this concerns “Data line connection parameters”. It is important that compression and hardware flow control are enabled, requiring minimal system resources. We leave additional communication parameters unchanged.

The function of manually setting the modem initialization string may also be interesting. To do this, you need to close the last customizable window and return to the previous one. At the top we see a line called “Additional initialization commands”. Each modem has a protocol that it uses, as well as commands that it supports. These commands are used to control the modem using the operating system. And the speed of the device and some other parameters will depend on how it is initialized.

For each modem you need to select your own line; to do this, you need to search the Internet for documentation on this device. By the way, if your modem can be reflashed, then you also need to monitor the release of the latest firmware versions. This is done using a special firmware program for a specific device model and, of course, the binary code itself, written as a file.

There are also so-called rollback firmwares so that you can return everything to its previous state if problems arise. There are special configuration programs for many modems. For example, software for modems on a Rockwell chip can be found at www.rampitec.spb.ru/modem.htm.

As for protocols, you need to use PPP for the channel, for everything else you need to use the TCP/IP protocol stack. IP header compression must be enabled, the DNS server (primary and backup) must be specified, WINS and NetBIOS must be disabled if it is in the settings. All this is done in the “Start” menu > “Settings” > “Control Panel” > “Network Connections” > properties of the selected connection > “Network”.

LET'S PLAY FAST
It's time to talk about the very games that cause us to quarrel with our family, keep a strict fast (only chips, crackers, seeds and beer are blessed), ignore study/work and cultivate a passion for weapons, mass murder and profanity. By default, the most popular 3D shooters of all time are Counter-Strike (Half-Life) and Quake. Let's look at optimizing your Internet connection for these games.

Recently, thanks to the popularity of these shooters and the great interest of all progressive humanity in them, special programs have begun to appear to optimize the dial-up connection when playing with Internet colleagues. For CS you can download AntiPing (a bit of an incorrect name, AntiLag would be more correct) at money-home.narod.ru/antiping.rar. This is a configuration file that needs to be copied to the directory where the game is installed, and the corresponding command must be entered in the console (the description in Russian is in the same archive).

A detailed description of console commands and new improvements in the latest CS patch can be found on the website counter-sport.by.ru/netgame/netgame.shtml. There are also all the cheat codes and tips for optimizing the game on the Internet.

There are also many utilities released for Quake 3 Arena that can be used to improve performance (and not just Internet connections). The most popular program today is Q3A – Total Control v0.6. You can download it at planetquake.com/borderfield. During installation, the program itself finds the installed version of Quake 3 Arena. Next, we launch the utility and in the Tools > Dial-Up Optimizer menu we see the window shown in the screenshot.

As you can see, there are all the parameters we described, the value of which was supposed to be changed manually.

There are many ways and approaches to optimizing your Internet connection for online gaming. This includes the use of special programs that manually or automatically set the required values for communication parameters, and alteration of the registry for your operating system and Internet channel using the regedit.exe utility, and changing two or three main registry keys. And don’t forget to export the registry on time.
