I've got a machine with a Gigabyte MB and an onboard NIC. I installed a wireless card and ran wireless for about a month. Now I need to go back to hard wiring it to the router.

My problem is that now the onboard NIC rarely works. All I get out of it is a steady blinking light on the router and a message that it's not getting an IP from the router.

Things I've tried:

1) Disabling wireless and enabling wired and rebooting.

2) Uninstalling wireless card, shut down and physically uninstalling wireless card and rebooting.

3) Install a PCI NIC and disable the onboard NIC. Still just a blinking light on the router.

4) Different ethernet cable

5) Different computer to test the router. The router works.

If anyone has any suggestions I'd appreciate it.

TIA
