I am using an intergrated nvidia nic adapter everything has been running great no problems till last night.

I logged on this morning and no internet access I opened a dos prompt and did ipconfig /all and found that my nic card wasnt grabbing dhcp from my linksys router. So I checked the other pc's that are conected to that router and they all have the right ip and subnet. So I did ipconfig /release ipconfig /renew and reboot , It still comes up with that other ip.
How can I unbind that ip from my nic. Is ther a virus out there doing this that I dont know of or what its driving me crazy LOL.

thanks for the help in advance

ipconfig /release should cause the adapter to return to a state with the default IP configuration (a 168.x.x.x address, I think).

Try removing the adapter and then re-installing it (Add/Remove Hardware).

Hi Rinkrat76,

It would help if you could post the results of "ipconfig /all"
It's possible you're getting a "169..." address - this happens if the PC can't contact the DHCP server for some reason.

I suggest checking your cabling carefully.

Reboot your router, try use other CAT5 cable or you can assgin an IP for your computer.

The ip I am getting is 169.2454.
The nic is onboard..

I disabled the nic and installed a 3com I had laying around and it was up no problem wich leads me to belive its the onboard nic.

I just tried to uninstall the 3com and re enable the onbard wich is nvidia onbard nic card. I got the same result 169.......

what is weird is i can ping the number so the nic must not be bad its just not obtaining the dhcp..
this is yukie..

Try to set a static IP within the subnet you're using, taking care to enter values for gateway and DNS (your linksys router IP). The IP you're getting is the one you get when the system cannot obtain a real address. If static IP works, the network interface is probably OK, but doesn't get a DHCP offer.

I am trying right now to see if I reinstall nvidia nforce drivers and configure the nic if that will fix the problem.

I am currious if anyone knows why it would just loose contact with dhcp from the router.

Rinkrat76,
It does sound like a dodgy NIC.

It happens occasionally - but is very annoying.
