I have a network card problem?

Question

system specs.: amd sempron 2800+ (64 bit) ; motherboard asus k8n-e ; 512 mb ram. the problem is that when I connect the utp lan cable to the onboard ethernet adapter it doesn't recieve packets. It isn't a broblem with the cable, I tryed it with another network card. the switch is trendnet 10/100 mbps. The onboard card is 10/100/1000 mbps nvidia nforce. The traffic monitorisation software that came with it shows me that it recieves packets but windows doesn't... I don't even have ping or arping. I disabeled the firewall too.

Answer 1

Ok a few simple things, when you plug up the cable, do you have any lights on the connector in the computer that might come on?One of them will be the link light, and the other will be the activity light.



One should be steady(the link light) and the other should blink(activity), not a steady blink but when data is being sent in and out of the interface.





Some things to check in windows,



1. Make sure that the network interface is ENABLED, and is not DISABLED.



2. Is this computer on a network using DHCP? If so, go into the TCP/IP settings for this network card and make sure it is setup to use DHCP and doesnt have an address in the fields, if so click on the spot to change the card to DHCP, and make sure it does DHCP for the DNS server settings as well.



If the computer is NOT on a network that uses DHCP, then set the IP address parameters to what is needed for it to work on the network.



3.Make sure to set the interface to 100mbs FULL duplex, Some network cards and switches (esp the cheap ones, which a trendnet is considered a cheap switch) sometimes dont work together for the speed sensing. if the 100 FULL DUPLEX does not work, then try 10mbs and HALF duplex, and see if this works. If it does work for you then, your network card chipset might be bad or it could still be an issue with the switch.



Did the network card work previously in this computer? If so, did you update a driver for it? This could be an issue, if so, roll the driver back to the previous one, this should fix it for you.



If none of this helps, then it is possible that the network card is bad, and will need to be replaced.

Answer 2

Reinstall the drivers for the on-board NIC. Make sure that it is enabled in the BIOS and in Device Manager. Make sure that it's configured to autoconfigure speed and duplex settings.



If it still does not work, it's probably toast. Disable it in BIOS and install another NIC, or replace the mother board.

Answer 3

dear member,



if your lan cable doesn't work on another computer then it's the cable. If your cable is confirmed properly working then it's your onboard ethernet adapter. buy a new NIC card and install it separately by 3com since integrated parts go out easily anyways.



kind regards,

Answer 4

This sounds like a driver issue. Are you running a generic windows driver or one designed for this chip set? Whatever the answer, have you tried the other alternative?
