Choose the right ISP
For users, when choosing an ISP (network access service provider), we often pay more attention to access costs, hourly service costs, etc., but we don’t know much about the network bandwidth provided by the ISP. When choosing an ISP, we should note that the export bandwidth of the ISP you want to choose is the bandwidth that is directly connected to your desktop. The network bandwidth that each ISP promotes is different. You need to figure out whether the bandwidth it says is exclusive or shared. For shared bandwidth, the more users you use at the same time, the slower your browsing rate will be. For different ISPs, we can call their customer service center or go to their business department to ask for relevant technical information, or search for relevant information on the Internet.
Check the current speed
Before optimization, it is necessary to check the existing network speed, prescribe the right medicine, and find the best network optimization solution for this machine, otherwise it is likely to cause abnormalities in the network.
When checking network speed, you can use "ping" to understand the relevant network parameters, or you can test the download speed by downloading relatively large files from relatively stable websites to understand the relevant network speed. Generally, users can detect network speed by using relevant software, such as "TCP Optimizer".
Optimize the registry
The most direct way to optimize network speed is to change the registry. You can refer to some information to modify the corresponding key values of the registry, but please note:
This operation may cause system instability or even crash. Please back up the registry in advance to recover in the event of a failure.
The modifiable key values are as follows:
1. MaxMT: Modify the maximum transmission unit.
2. DefaultRcvWindow and DefaultTTL set the size value of the transmission unit buffer and the TCP/IP packet life.
3. Set DNS query priority: improve the browsing speed of web pages.
4. Improve the RAM used by TCP/IP: Increase the buffer used by TCP/IP to increase the data rate.
Free up reserved bandwidth
The Win XP system can generally improve the network data transmission speed by using the RSVP protocol in QoS (Quality of Service). However, if the application used by the user cannot use the QoS API well. (Interface program) will occupy network bandwidth, which will lead to network traffic congestion. The network can be "speeded up" by modifying the value of reserved bandwidth.
First, log in as an administrator and run the command "gpedit.msc" to enter the "Group Policy" edit window. Click "Computer Settings", "Management Module", "Network", "QoS Packet Scheduler", and then select "Limit Reservable Bandwidth" on the right, right-click it, and select "Properties" to open its properties window. Change the corresponding value of "Limited Bandwidth" to "0" to release the reserved bandwidth.
Optimization software
For ordinary users, it is inconvenient to use the above methods to modify the registry after all. We recommend that users use certain optimization software to optimize the system. Take TCP Optimizer as an example.
This is a small, powerful and green software, without installation, and the operating interface is also very simple. The download link is: http//www. speedguide. net.
It is recommended that users first click "MaxMTU" to check the relevant parameters of the network used by the user. However, when entering the address of the website, it is best to choose the address of the local ISP instead of using its default URL; the same is true for "Latency PING". In the "Settings" tab, we select the type of Internet modem we use, then select "Optimal Setting" at the bottom of the above interface, then click the "Apply changes" button, and restart the computer and take effect.
Dialing software is also important
For ADSL dial-up or virtual dial-up users, it is also important to choose the right dial-up software. For users who use Windows 98/Me/NT/2000 and other operating systems, because there is no dialing program that supports PPPoE protocol in the system, users have to install the relevant software themselves. At present, the more mainstream dialing software that supports the PPPoE protocol are: WinPoET, EnterNet, RASPPPoE, etc. These software have their own advantages; based on various factors such as the stability and speed of each software, it is recommended that ordinary users choose RASPPPoE. For Windows XP users, because the system has built-in dialing software, it is recommended that users use it because its system compatibility and stability are very good, and data outages rarely occur. Setting method: Select "Start → Settings → Control Panel → Network Connection → New Connection Wizard" to establish a network connection, and select "Connect with a broadband connection requiring a username and password".
Please follow the screen prompts for the rest of the operations. After the settings are completed, you can find the connection you just established in "Start → Settings → Network and Dial-up Connections", and you can use it to realize virtual dial-up Internet access. Of course, you can also use other virtual dialing software, just don’t install two or more dialing software in the same system, otherwise it will easily cause conflicts and lead to inability to access the Internet.
