Many students complain that the school's dormitory network is very unstable, the Internet speed is fast and slow, and sometimes it will inexplicably break the network, which makes the students who love online games can not afford to hurt. The system home analyzes the causes of network instability and gives solutions to network instability. First, the cause of network instability There are many reasons for network instability, in addition to the hardware aspects of the line (this situation is less, should be resolved by the telecommunications part), from the software side, there are generally the following reasons . 1. Multiple computers share Internet access, and the shared network may have ARP virus in the computer, which is caused by attacks on other computers. 2. Many people use the music player to play songs online at the same time, because it takes a lot of bandwidth to get songs and download lyrics. 3. Someone in the intranet uses P2P download software, such as Thunder, Internet Express, QQ Cyclone, Network Video Accelerator. The working principle of P2P is to upload data to the host at the same time as downloading the file, and upload the content automatically, and complete the resource sharing between the users. If your P2P software is set to boot from the boot, once the computer is turned on, it will automatically upload data (regardless of whether you are using this software), the larger the upload data, the impact on the speed of playing games, sending mail, browsing the web, etc. The bigger, so that the netizens are silently swallowed without the knowledge of the netizens. Second, to solve the network instability countermeasures Network instability, generally can be solved by off-the-shelf tool software. At present, the most useful tools are system maintenance tools such as Jinshan Guardian and 360 Security Guard. Jinshan Guards to solve the problem of network instability to determine the actual speed of the network First understand what your current network environment is like. Open the main interface of Jinshan Guardian, run “network speed”, Jinshan Guardian will calculate the network speed with accurate data, and according to the current network situation, suggest which network applications are suitable for the current network, such as online movies and online games. Find out who is the traffic If you find that the network is unstable, immediately turn on the traffic monitoring function, first check which processes you use, which processes consume a lot of network bandwidth (for example, you are using P2P software, such as Thunder, QQ whirlwind, etc.) Then limit the speed of the process. Open the main interface of Jinshan Guardian, enter the “Traffic Monitoring” function, and find the program that takes up a large amount of traffic to limit the traffic. Rejecting intranet attacks If the network environment you are in is a LAN, it is recommended to open the Kingsoft ARP firewall to check if there is an ARP virus, which causes the network to be unstable. If there is an ARP virus attack on the LAN, the Jinshan Guardian ARP firewall will alarm, prompting an IP computer to issue an ARP attack on your computer, then contact the network management or the user in the network to use anti-virus software to disinfect the attacking computer. Through the above simple steps, the problem of network instability can generally be solved. 360 security guards to solve the problem of slow network If you open the browser slowly, you can try network speed optimization, system repair, and then further through the upgrade IE and replace the 360 speed browser and other measures to solve. Optimize the acceleration + system repair first through the 360 security guards' "optimization acceleration" function to optimize the network speed, and then through the 360 security guards "system repair" system repair. Upgrade IE or replace the speed browser If the problem still remains unresolved, you can upgrade the IE browser version or replace the third-party browser such as 360 speed. Uninstall the original IE browser before upgrading the browser. Uninstall IE8: Open 360 Software Manager, click on “Software Uninstall”, click on “Browser” on the left, find IE8 on the right, then click on the “Uninstall” button on the right, in the pop-up window, follow Prompt to uninstall IE8. Uninstall IE9: Find the cmd command by clicking the “Start” dialog box, right-click and select “Run as administrator” and enter the following command (Figure): FORFILES /P %WINDIR%servicingPackages /M Microsoft-Windows-InternetExplorer- *9.*.mum /c "cmd /c echo Uninstalling package @fname && start /w pkgmgr /up:@fname /norestart"Try after reboot. An error will be reported during the operation, just click “OK” Reinstall the new version of IE: Search for the corresponding version of Internet Explorer (Internet Explorer) from the 360 software housekeeper to download and install. For quick installation, check the box to check “ I don't want to participate immediately, then click “Next”, click “ I agree & rdquo;, remove the check for “install update”, do not update. Follow the prompts to install and restart your computer. In addition, 360 Flash browsers can be downloaded from 360 software housekeepers, or non-IE kernel browsers such as Firefox. Tip: If it is a network disconnection phenomenon, first check the connection between the network cable and the various devices, and then find the reason for the network disconnection according to the error type of the broadband cat, and then uninstall and reinstall the network card driver. If it still cannot be solved, press the above. The software solution is processed. This article comes from [System Home] www.xp85.com
