网线老是掉的原因（The reason why the cable always goes off）

网线老是掉的原因（The reason why the cable always goes off） 网线老是掉的原因(The reason why the cable always goes off) First, check the CPU and graphics cards, heat, dust, oil, or replace the fan. Two, the power supply voltage is unstable, the power supply is insufficient, the replacement of high quality power large power supply. Three. Clean up the disk and defragment the disk. 1, in the my computer window, right click to clear the letter - "properties" - "disk" -- check the file to delete -- is determined. 2, remove temporary files, start - run - enter%temp% - determine. 3 、 use the optimizer or super rabbit to clean up the registry and junk files. 4, close some startup procedures, start - run -msconfig--- start, in addition to antivirus software, input method, general procedures can be turned off. 5, delete the program software without. 6, defragment disk -- start -- all programs -- attachments -- system tools -- disk defragmentation -- selected C-- analysis -- defragmentation. 7, reduce memory burden, open procedures can not be too much. If you open too many documents at the same time or run too many programs, you don't have enough memory to run other programs. You should always close unused programs and windows. Four 、 upgrade mainboard, video card and network card driver. Five, increase physical memory, change to high-quality memory, and set up virtual memory. 1, play games, virtual memory can be set larger, the minimum value of physical memory 1.5 times, the maximum value of physical memory 2-3 times. It's too big to take up too much hard disk space. 2, the virtual memory setting method is: right click on my computer - properties - advanced properties - Settings - Advanced - virtual memory change in the drive list and select the virtual memory (page file) stored in the partition - Custom Size on setting initial size "and" maximum value ", and then click set the last" button, click "OK" button to exit. 3, virtual memory (page files) storage of the partition, must have enough space, hard disk resources are insufficient, resulting in virtual memory is not enough. The use of ADSL online, often encounter web pages can not open, Download interrupted, or online video and audio stream interruption, QQ drop line, game drops and so on. We might as well assume that the landlord is using the ADSL internet. In fact, the reasons for dropping frequently in other ways are similar to the following reasons. Now let's analyze the reasons for ADSL dropping. First, the line problem First of all, check a home line, see if the house is connected, whether the line through what interference sources, such as air conditioning, refrigerators, television, etc., and try to maintain a certain distance with these electrical equipment. You can also use your own indoor line to replace the cable with stronger anti-interference ability. Make sure the line is properly connected. The telephone line is connected to the junction box after entering the home, and then separated to the voice separator. The front line takes the telephone and the front line goes MODEM (marked on the separator). At the same time, ensure that the line communication quality is good, not disturbed, there is no connection to other equipment that will cause interference to the line. Check whether the junction box and the crystal head are in bad contact and whether they are wound together with other wires. Conditional, it is best to use standard telephone line, PC, ADSL, Modem attached twisted pair. The line is one of the important factors for the quality of video access. Cable from the users within 100 meters of the radio tower, electric welder, tram or high-voltage power transformers and other signal interference sources, the user can receive offline clutter (copper clad steel wire shielding ability is weak, the received signal), caused by strong interference on the subscriber line. The interfering signals are often unshielded, and the offline part enters, because the relay cable has a shield that interferes with and affects very little. If you use a few shielded wires in a very disturbed place, you will reduce the speed of the interference caused by instability or drop line phenomenon. In addition, the power line cannot be connected with the ADSL line in parallel to prevent crosstalk and cause ADSL failure. In addition, there are many other factors that cause network instability, such as signal interference and software conflicts. Mobile phones such a large radiation things must not be placed next to the ADSL Modem, because every few minutes, the phone will automatically find the network, when the powerful electromagnetic interference enough to cause ADSL Modem cut. Two, network card problem Network cards are generally PCI network card or onboard network card, select the time to choose a better quality, otherwise it may cause poor quality of the internet. 10M or 10M/100M adaptive adapters are available. In addition, many machines to share Internet access, using a dual card, which is the cause of conflict is also worthy of attention, then, should pull up connected to the LAN or other computer network card, only connect to the ADSL Internet card test, if the failure to resume normal, and then check the two network cards have no conflict. Three, ADSL, MODEM or network card settings Now, MODEM generally has 2 modes of work, one is the normal mode of using dial-up software, and the other is the automatic dial-up routing mode. In normal mode, you do not need to set up the MODEM, but you can use the default. The routing mode needs to be set, and MODEM has its own flash memory. The account and password box can be stored in the phone and automatically dialed. The most common method of this method is to set the wrong ADSL Modem address of the DNS IP or to set the server incorrectly. Because for ADSL virtual dial-up users, there is no need to set the IP address, automatic allocation can be. TCP/IP gateways generally do not need to be set up. However, the DNS must be set properly and the DNS address can be obtained from the local telecommunications department. In addition, the TCP/IP settings are most likely to cause you to not browse the web, generally set to automatically get the IP address, but DNS must fill in. Others can be accepted by default Four, ADSL Modem synchronization exception Check your phone line and ADSL connections are bad places, or telephone line problems, poor quality of the phone is particularly likely to cause dropped, but this problem is not good, so be sure to use good quality telephone line. If the suspect separator is bad or ADSL Modem is bad, try not to use the splitter to access the outside line directly to ADSL Modem. The separator should not be too long to connect with the ADSL Modem, otherwise it cannot be synchronized. Excluding the above, as long as the reset ADSL Modem, you can solve the synchronization problem. Five, operating systems, viruses In addition to the line conditions mentioned above, there are also problems with the computer system. For example, legend killer causes LAN to be dropped. The problem has occurred all over the country, The virus has an impact on both host agents and Internet cafes (local area networks) of router agents. Legend is a killer on the LAN ARP spoofing, virtual gateway address, the legendary game to collect LAN login information and analysis to obtain user information damaging software. Working process: first, the MAC through the ARP Spoofing broadcast to the LAN, the LAN of workstations mistaken for machine is the gateway this process will cause the LAN and the Internet connection is interrupted, and make the game server disconnect the link. To restart the game and user account login, account information and not directly to the proxy server through the gateway upload, but being uploaded to ARP deception legend killer software. By decrypting the legendary killer of its own means, real the username and password will be the account. So as to achieve the purpose of attack. Steal game player account status: LAN and the Internet link speed suddenly slow down or even off. The network game disconnects the link and returns the server after it is re landed. Firstly, killing the virus; if you can reinstall the system; such as machine using a double card, uninstall a network card; suggestions for computer is not very familiar with the users don't install firewall software, set incorrectly will cause the instability of the internet. Some operating systems may have compatibility issues with ADSL related components, so that Microsoft can upgrade the system or repair the system. The conditions can reload. If the software is in conflict, try to find conflicting software, uninstall it, or otherwise resolve it. Six firewall, IE browser settings wrong Although ADSL is less likely to be attacked by hackers and viruses, it does not rule out possibilities, especially web viruses and worm viruses. If the virus destroys the ADSL related components, there will be a disconnection. If you can determine by the destruction of the virus and attack, you should check the installation of the firewall, Internet sharing software, internet proxy server software also accelerated the occurrence of drying phenomenon, stop the operation of this kind of software, then the internet tests, see whether the speed of return to normal. If the Internet is unstable, you can try to shut down the firewall, test stability or not, in the corresponding settings. In addition, the firewall causes or IE browser failure, can also lead to normal connection, but can not open the web page. Seven, electrostatic problems Static electricity is an important factor to affect the ADSL, and the power house is generally not ground, plus a variety of electrical appliances (such as refrigerators, TV) interference, it is easy to cause the electrostatic interference, resulting in the use of ADSL frequently dropped, please send the three core socket grounding end of the lead wire and well grounded, general can solve the line problem. General solution: to increase the grounding wire, to solve the problem of dropping. Eight, software conflicts ADSL access to Internet, there are two types of virtual dial-up and private access, and now most of the individual users of ADSL virtual dial-up. PPPOE (Point-to-Point, Protocol, over, Ethernet, peer to peer protocol) virtual dial-up software has its own advantages and disadvantages. After multi-party testing in different operating systems, if the operating system is Windows XP, it is recommended to use its own PPPOE dial-up software, the phenomenon of disconnection is less, Stability is also relatively improved. If you are using Windows, ME, or 9x, you can use the following virtual dial-up software --EnterNet, WinPoET, RasPPPoE. Among them, EnterNet is now a more commonly used, EnterNet 300 applies to Windows 9x; EnterNet 500 applies to Windows 2000/XP. When you have problems with a PPPOE dial-up software, you can uninstall this software and replace it with an additional PPPOE dial-up software. Be sure not to load multiple PPPOE software at the same time, so as not to cause conflicts. Because the telephone line is the main way of broadband access, and so we must set up a virtual channel, if several dial-up software loading can lead to conflict, resulting in network and its instability. If the software is in conflict, try to find conflicting software, uninstall it, or otherwise resolve it. For example, some friends BT download will lead to network dropped. It may take too many threads to download, resulting in disconnection. In addition, the reason for the drop is not only your own server, but also your server's limitations and the server's attacks or failures
