Common failures caused by network card driver and solutions

[enrique1985]

Startup speed slows down after installing network card driver Failure symptom: restart computer after installing network card driver, and startup speed slower down obviously Solution: first eliminate errors happened during the driver installation. Generally speaking, when setup network configuration, then system has an extra inspection for network card, which let system slower in starting up more than before, this is normal. Besides, if you haven’t specified an IP address for the network card, when starts up, system would auto search an IP address for it, which almost takes about 10 seconds. Therefore, even the network card is not in use, you’d better to assign an IP address for it, or to disable it in BIOS, then the speed could be advanced. Problem sum-up: network card problem happens rarely of network hardware failures. In all, the failure sources mainly are on network card driver and transmission speed match (namely, connected software problems); general solution is to uninstall the driver and reconfigure network cared parameters. Solution for network card driver problem As virus killing, abnormal shutdown, network card driver might get broken. If it does break, then network card refuses to work, network is blocked by “Ping” even with the indicator light on. At this moment, we go to “Control Panel”—“Systems”—“Device Manager” option, check the driver to see if the network card is good or not. If the icon of the network card displayed in “Network adapter” has a yellow “!” mark on it, then it indicates that the driver is abnormal, you need to reinstall driver. Uninstall stubborn network card driver My computer connects to the Internet by school LAN, host computer’s PCI slot separately installs network card and sound card. As to change the main box, we’d have to take apart all and reconfigure. And worse is that I couldn’t remember which PCI slot the original network card was on. So, whatever, I plugged it to one of the slots randomly. Entering Win 2000, system automatically found the network card, but there was a mark “#2” behind the name of the network card. But it could not work when I used it. I checked the properties of “Network Neiborhood”, found none set there even IP, so I had to reset them all again. Finally it still could not get to Internet. Then I began to doubt the name of the network card, hadn’t I uninstalled the original network card? Did it conflict with current new found network card? Right click “My computer” and choose “Properties”, click “Hardware”—“Device Manager”, check the network card. But there’s only the one with “#” mark. Click “View” in the menu—“Display hidden devices”, still no sign of original network card device, so how to delete it? Should I only to take the machine apart and change slot position for the network card? I opened Control Panel again and suddenly I noticed there’s an extra item “Add/Remove hardware”, double clicked it, and clicked “Next”, chose “Uninstall/Pull out devices”, and clicked “Uninstall the device”. And the dialog listed the hardware to uninstall. Select the below “Display hidden devices”, Waaaa….. I got my original network card name back (without the mark “#2”), and uninstalled it. Returned back to “Device manager” in “System properties”, chose “Operation—Scan hardware modifications”, and the network card found this time had no # mark. At last, opened the properties of “Network Neiborhood” and followed original configuration steps,. Reconfiguring IP , gateway ,subnet mask, and DNS. Open IE to check it up! OK!. It connected And the “Failure” about network card this time tells me: if in Win 2000/XP, if there’s any change on network card device, you’d better first to uninstall the network card from device manager, avoiding getting problems when install network card again.
