Broadband is always dropping（宽带总是掉线）

Broadband is always dropping（宽带总是掉线） Broadband is always dropping(宽带总是掉线) A problem, first check the home line line, see inside joints are connected, the line is through what sources of interference, such as air conditioning, refrigerator, TV, as far as possible with the electric equipment to maintain a certain distance. 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, the network card problems, network cards are generally PCI network card or onboard network card, select the time to choose the 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, MODEM now generally has 2 modes of work, one is the use of dial-up software in the normal mode, one is automatically 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 is abnormal to check their own telephone lines 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, the operating system, the virus problem, in addition to the above-mentioned conditions of the line, there are computer systems problems. 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. 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. 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, ADSL although hackers and viruses are less likely to attack, but it does not rule out the possibility, 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 electrostatic problem is an important factor affecting 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 lead wire and good grounding, can solve the general line problem. General solution: to increase the grounding wire, to solve the problem of dropping. Eight, the software conflict problem, ADSL access to Internet has two kinds of virtual dial-up and private line access, and now most of the ADSL of individual users is 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 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 phone line is the main mode of broadband access, and that must be 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.
