Computer drop-Line solution

First, whether the power signal light is constant bright


  


if the power signal light is not bright, first of all to troubleshoot power problems. 　　    If it is due to the power supply instability caused by the line, ADSL modem itself, whether there are problems.


Hand Touch ADSL Modem shell, feel very hot, at this time may be the ADSL modem temporarily shut down until cooling and then power-on use, or put it to the more ventilated position, this can also eliminate line failure.


 


Second, check whether the network cable is loose


for most broadband users, ADSL cat wireless router Network is the most common way, when there is a drop in the situation, we should first consider the line problem.


  


because the phone line too long, too many joints, or there are some sources of interference, it is likely to trigger off the line, there are poor quality, do not meet the standard network cable will often cause instability, so when the discovery of the line, we must first check the cable interface is loose.


  


If you find that the cable interface is intact, check the problem of the power signal light.


Three, check the data signal is normal


 


if the data signal light is not bright, it is likely that the circuit appears circuit breakers, short-circuit and other phenomena, and then through the telephone test to see if the line is normal, if not normal, you can help ADSL service provider's technical staff to solve this problem.


if the data signal light flashing, it is likely to be caused by bad line contact, you have to check whether the extension, the connector is firm, ADSL connection line is too long. If you follow the steps above, the data semaphore is still not bright, indicating that the fault is not connected to the line, and continue to look for other reasons.


 


Check if the dial-up software is working properly


  


First, double-click the dialer on the system desktop with your mouse. To perform a broadband dial-up connection operation, you can click the "Retry" button in the prompt window if you find a "failed to connect" error prompt during the dialing process, which normally can be dialed 3 to 5 times to solve the problem.


  


If you dial 3 or 5 times and you can't connect again, we can consider the broadband "cat" power off for a period of time and then open, and use ping to test the broadband "cat" IP address, if you can ping broadband "cat" IP address and then redial operation, I'm sure this will solve the problem.


  


If you still can not successfully dial, you may wish to restart the computer system, and then repeated dialing; If such efforts can not solve the problem, it is likely that the telecommunications room data machine will lock up the user account, this time we can only contact the telecommunications staff to help unlock the.


  


if the TCP/IP parameters are not modified, you can now remove the TCP/IP protocol, then reinstall it and set it properly, which may resolve your line failure.


five, network card signal is stable


under normal circumstances, the computer network card through the network cable and ADSL modem connection, its signal should be flashing or constant light. If the network card semaphore is unstable state, that is, not bright or flashing, it is likely that the network card and network cable Connection has failed.


  


In addition, also need to check whether the network card is loose, NIC driver installation is correct, network card resources conflict, network cable connector is loose. If you still cannot return to normal, the failure is not caused by a network card or network cable.


Five, network address can not conflict


if the IP address of the ADSL modem is in conflict, or if the DNS server address is set incorrectly, it will also cause ADSL off line.


  


If you are a virtual dial-up user, you do not have to set the IP address, as long as you choose to automatically assign it. If you use a fixed IP address, you must check whether the IP address conflicts with the IP address of other workstations in the network segment, and check that the DNS address is set correctly and that the TCP/IP parameters have changed. 　　   　  When you're done with the troubleshooting, if you still can't eliminate the problem, you'll have to look for the reason for the dial-up software.


six, heavy load


 


heavy load is also caused by the broadband drop in one of the reasons, such as our frequent use of BT, such as the broadband sharing network, some people are in the BT download, it is likely that the load is too large, so that the router off the line, this situation in the student dormitory or small office network.


in order to avoid this situation, you can limit the BT download of the flow and bandwidth, so as not to affect the normal Internet for other users, especially such as CM, fttx+lan such as shared broadband, crazy Peer-to-peer download is caused by network paralysis or the main cause of the frequent drop line. 　　Of course, we can also exchange a faster connection to see whether the connection speed is normal, or reduce the download burden. 3lian Material


Seven, the number of shared broadband machines


 


because the general router has a limited number of machines, no line from the same. 　　 When the wireless router with too many machines will cause the network load is too large to appear panic, drop the problem appears.


in order to avoid the above situation, we can limit the processor and cache performance, reduce the number of wireless router band.


Eight, infected with the virus caused the Internet to drop the line


 


Especially resident student users, is generally a router to connect several machines, so that the virus attack probability will be very large, so effective protection against the virus will avoid the router or even more serious fault. For experienced users, it is possible to realize that this is most likely a result of a virus when they find that they are experiencing a slow pace of accessing a LAN or regular operation. At this time we can use the new version of anti-virus software to kill, or Ping gateway to view the flow of the method to locate the problem.
