College】 【weak allergic reactions can not dial-up problems to solve network card.

<br> <BR> many home users are conducted through the residential broadband ADSL access to dial-up, the way in the use of the Internet, they often encounter the phenomenon of failure can not dial-up! .This does not, when we randomly plug in the computer hardware operation, a number of LAN equipment unplugged and even produced this "allergic" reaction, eventually causing the failure can not dial-up Internet access. .Now, this failure will be such a strange phenomenon and contribute to the troubleshooting process, and hope to bring friends to give you some help! .<BR> <BR> <BR> <BR> Symptoms more readily to be able to play online games better, I always like the way to get through overclocking the computer's video card "overload" work, but in a recent Cheong .play the game, suddenly re-start phenomenon, and the emergence of a black screen. .<BR> <BR> Failure, I subconsciously think the failure was due to overclocking graphics cards for a long time after working temperature is too high or there is bad video card problem, so I immediately turned off the computer until the display card .After natural cooling, carefully pull it from the motherboard to, over time, again it is correctly inserted into the motherboard. .<BR> <BR> Sure enough, when the computer is turned on again, I found the screen blank screen has been successfully resolved. .However, when I double-click the desktop with the mouse in the dial-up connection icon and click interface, then the "Connect" button when ready to surf the Internet, see the screen pop up a "Connection in progress ... ..." the message, then, .After the corresponding prompt is "suspended animation" state. .<BR> <BR> <BR> <BR> Troubleshooting fault in the encounter that, I thought it was a problem with dial-up line, but the network card in Control Panel double-check the chain of lights and the lights display the status, we found that they .everything is normal, indicating that the local computer's network card device and the cell line connection between the switches are reliable and correct. .<BR> <BR> Since dial-up connection lines are open, why can not I be on the local computer dial-up it? .<BR> <BR> Taking into account the graphics card before the plug, I can dial the normal operation, which indicates the local computer dial-up parameters are correct, but also the basic rule and the virtual dial-up network virus program error .attack and other factors, why would occur after mating display card failure can not dial it? .Is equipment and re-insert the card display card device resource conflict occurred, resulting in network card device is not working? .<BR> <BR> I think to do, immediately turn off the computer power supply, and quickly open the host chassis, and then the card slot device from a diversion to another slot, then turn the computer off and re-dial-up .Internet operations, but such efforts have not achieved any substantial results. .<BR> <BR> Failed in this effort, the author estimated install the network card in their computer equipment, there may be a hardware failure, so specially went to the market to purchase a new card back a piece of equipment, and then carefully follow the correct method .installation of new network card into the computer, the working parameters and network card were reconfigured, but when I try again to dial-up operation, still found it impossible to connect to the Internet network. .<BR> <BR> In desperation, I had to call a local ISP in order to seek their help. .<BR> <BR> Technical personnel rushed to the fault phenomena, the first test the connectivity of the network cable and found that the network connections as usual. .Turn a good test that comes with network cable into the notebook computer, then dial-up operation, quick to see the dial-up success tips, and unfettered access to the Internet network for any content, it is clear area broadband network and .connections without any problem. .<BR> <BR> Why the network cable connected to the computer when I can not dial it? .<BR> <BR> The technical staff listened to a detailed description of the author, after the failure that is likely to be from the local computer's network card device caused, he believes some of the older models of adaptive equipment may be other hardware card .The unplugged and produce "allergic" reaction, which easily lead to be some hidden card equipment failure, or cause the computer system can not correctly identify the network card device, so if the fault can not dial-up phenomenon will occur. .<BR> <BR> I immediately right-click the desktop computer in the "My Computer" icon from the shortcut menu to perform the "Properties" command, go to the local computer's System Properties dialog box, click .The "hardware" tab, and in the corresponding tab page, click "Device Manager" button to open the list of devices the system interface. .Interface in the list, I use the mouse double-click "Network adapters" option, then expand the branch from below the target card I do see the device icon appears above the yellow exclamation mark, it is clear card and display card device equipment has occurred .resource conflict, the conflict is caused because of this sudden network card device can not connect to dial-up server, and ultimately caused the failure can not dial-up Internet access. .<BR> <BR> Troubleshooting <BR> <BR> reason to find fault, we just click on the appropriate card to re-set the device to enable computer systems to correctly identify the network card device, can solve the fault can not dial out, .LAN equipment in the re-set the time, I was carried out according to the following steps: <BR> <BR> first follow the previous steps to open the System Device Manager window, double-click in the window "Network Adapter" option, .then expand the branch from the selected target network card device icon below, and right-click the icon, then right-click menu in the implementation of the "Properties" command, open the configuration interface card device properties. .<BR> <BR> Next click the property set interface "Advanced" tab, go to the tab settings page. .<BR> <BR> Page in the "Properties" list box, select "LinkSpeed / DuplexMode" option, then the right of the option "value" drop-down list, select the except "AutoNegotiation" anything other than .an option, then click "OK" button, and finally restarts the computer system about. .<BR> <BR> Until the system restarts successfully, the network cable back into the network card device, and try to dial-up Internet access operation, the results I found that symptoms were excluded, and LAN equipment to work properly. .Summary <BR> <BR> <BR> <BR> fault troubleshooting procedures summarized above, I believe that card is a hardware device unplugged and other special "sensitive" equipment, in our hardware unplugged inadvertently ., the card may be quietly performance changes, and can even cause the system can not accurately identify it, that way all kinds of inexplicable network failure can easily occur. .The card's "allergic" reactions rarely cause people's attention, so when faced with a network failure phenomenon, few people would think that the failure by the card's "allergic" reactions caused in that case the exclusion of network failures .much easier process, we make detours, resulting in network troubleshooting efficiency in serious decline. .<BR> <BR>.
