Weak current College】 【processing computer fault-net/off line of conventional techniques.

<br> <br> First, check the network cable is loose <br> <br> For most broadband users, ADSL wireless router cat received net way is most common, when dropped, our first consideration is the line problems. <br> .<br> Because the phone line is too long, excessive, or joints exist some disturbance sources, may very well have thrown off the line, poor quality, do not conform to the standard network cable often causes network unstable, so when you find out .the line that you want to first check the network cable connector is loose. <br> <br> If you find that the network cable interface intact, to check the power light. <br> <br> Second, the power light is lit .<br> <br> If the power light is not lit, it is first necessary to troubleshoot power problems. If the utility power supply is instability drops, power ADSLModem itself if there is a problem, etc. <br> <br> Hand .touch ADSLModem shell, feel very hot, you may wish to temporarily shut down till ADSLModem cooling and power on the use of, or including it to compare the ventilation position so that it can eliminate off line failure. <br> <br> 3. .check whether the normal data signal <br> <br> If the data signal lamp is not lit, it may well be lines appear circuit breaker, short circuit, and other phenomena, and then call the test to see if the line is normal, .if not properly, you can help-ADSL service provider's technical staff to resolve this issue. <br> <br> If the data signal lights flashing, then most likely caused by a bad line, you must check whether or not to use the extension ., the connectors firmly, ADSL connection line too long. If you follow the steps above inspect finished, data signal light still not lit, indicates that the fault has nothing to do with the line, and continue to look for other reasons. <br> .<br> IV. the stability of the network card lights <br> <br> Normally, the network card in your computer through a network cable and connect it ADSLModem of signal lights should be flashing or lit. If the network card lights appear unstable .state, that is not on or not blinking, then most likely the NIC and the network cable connection has failed. <br> <br> In addition, you need to check the network connection is loose, the network adapter driver is properly installed, .the NIC resources whether conflict occurs, the network cable connector is loose. If you are still unable to return to normal, the fault is not a network adapter or network cable. 5. network address does not conflict <br> <br> If ADSLModem .IP address conflicts occurred, or the DNS server address settings error, can also cause ADSL off line. <br> <br> If you are a virtual dial-up users, you do not have to set the IP address yourself, simply select the .automatically assigned. If you use a fixed IP address, you must check the IP address of the other within the same network segment and the workstation IP address conflicts arise, also check DNS address is set correctly, the TCP / IP parameters have changed. After .completing the troubleshooting work, if you still cannot eliminate the fault, you'll have from dial-up software, look for reasons. <br> <br> 6. check the dial-up software is working properly <br> <br> .First of all, double-click System desktop Dialer, performing broadband dial-up connection, if found in the dial-up process in the system has a "cannot connect" error when you are prompted, you can click on the prompt window "Retry ."button, normally you can redial 3 to 5 times to solve the problem. <br> <br> If the Redial 3 to 5 times after you cannot successfully connect, we can consider broadband" cat "power down for some time and then open .and use the ping command to test broadband "cat" IP address, if you can Ping Tung broadband "cat" IP address, and then redial, believe that most of them can solve the problem. <br> <br> If you still cannot .successfully for dial-up, think of a computer system to restart, and then repeatedly dial; if such efforts would not solve the problem, it is most likely that the telecom room data machine will lock up the user account, this time we can only .contact the telecommunications staff help unlock. <br> <br> If you do not modify the TCP / IP parameters, normal Internet access, then it may wish to remove the TCP / IP Protocol, and then reinstall and correctly set, this might be .able to solve your off line failure. <br> <br> 7. load is too large <br> <br> The load is too large or is the leading broadband dropping one of the reasons, such as our regular use of BT, .such as broadband sharing network in some BT download is in progress, it is very possible load is too large to allow the router off line, this number appears in the dormitory or small office network. <br> <br> To avoid this, you .can restrict the flow of BT download and bandwidth, without affecting other users the normal online degrees, especially like CM, FTTX + LAN such shared broadband, crazy P2P download is causing network paralyzed or dropped frequently. Of course we can also change the connection speed .of large station to see whether the connection speed or ease the burden for download. <br> <br> 8. sharing broadband camera number <br> <br> As a general router machine limited wireless routing. When the wireless router with too much .time will cause the network load is too large to panic, off line problems. <br> <br> To avoid these situations, we may be limited to the processor and cache performance, reduce wireless router machine number. <br> <br> .9. viruses causing Internet disconnectsBR> <br> In particular, students in residence, usually a router to connect several VCL, the probability of such viruses can be very large, effective protection against viruses will avoid router disconnected even more serious fault. For experienced .users, when discovered access LAN or normal operations are slow, be aware that this is probably caused by a virus. At this point we can use the new version of antivirus software for killing, or PING gateway with a view to positioning the flow. < .br> <br> <br> <br> <br>.
