机子老掉线的问题解决（The problem of dropping the old computer）

机子老掉线的问题解决（The problem of dropping the old computer） 机子老掉线的问题解决(The problem of dropping the old computer) The problem of dropping the old computer The problem of dropping the computer? Master gate, I always drop the computer, is the network card or system problems ah?. Another problem: my friend is a residential broadband light cat + switch (16) on the Internet, the existing 8 users, known as per port control 2Mbps, download is about 300KB, the original has been relatively normal, but in recent months, whether using FlashGet download tools or not, the direct use of IE no matter how big the file download, download the file, if the time will be more than 5 seconds is not finished, it will immediately dropped, but can not open the page, dropped to a few minutes to continue to connect and download, this cycle, if direct download the download process there is no response and cannot be activated by IE. And I also online QQ has been online, and chat card has been simultaneously with the QQ transmission line, the file has been transferred will not be broken. If you open the BT download, BT is also normal download. If it is to open the page is opened in any case can browse, occasionally timeout, refresh can be opened for specific performance at first second slower download, second, third seconds to reach 300~500KB or even 800KB, fourth seconds immediately dropped to tens of K, about fifth, sixth seconds down to 0 K do not know why, my system is installed XP P4 384MB 60G, and the normal use of the machine in the district can not be moved to ordinary families, ADSL Internet all normal, just open the page a bit more slowly. You look at me Answer: use ADSL to get online often meeting webpage cannot open, Download interrupt, or online watch, audio frequency interrupt, QQ drops line, game drops the phenomenon such as. 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 a ADSL fault. 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, and the virus has an impact on 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. The user to restart the game and 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, will be the account with the real username and password. 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. Online game broken links, and that there is no corresponding server after landing again. 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. Conditional, can be reloaded. 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 less cut, 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 a problem with a PPPOE dial-up software, you might as well uninstall the software and replace it with an additional PPPOE dial-up software. Be sure not to load multiple PPPOE software at once, So as not to cause conflict. 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 reasons for the QQ and the game drop may be related to their own server limitations and server attacks or failures, in addition to your own computer.
