NIC polarity mismatch?

[Raves]

Woke up this morning to my PC telling me 'network cable unplugged'. I check the connections, and noticed the the LED above the port on the router to which my cable was connected was flashing.

A net search revealed that this indicates a polarity mismatch.

I enabled/disabled the NIC in XP and in the BIOS, and I reinstalled the drivers. I also tried a different cable - no results.

I swapped in a wireless card, and its working fine.

So what do you think? Is my onboard NIC toast?

Can a polarity mismatch be fixed?

Have you tried another cable?
Have you tried another port on the router?
If you have and neither helped, then the NIC is probably borked. Might be easiest to disable the onboard and buy a PCI one.

as el_watcher says try a different cable and another port on the router.
It's also worth rebooting the router as sometimes a switch/router port can get confused if you've had a faulty cable/nic connected.
I spent 30 minutes Christmas day trying to work out why my nephews new PC wasn't connecting to the network - it turned out where i'd repaired the network socket in his room a few days earlier the switch was still locked on the port connected to that cable, in the end (after checking all the wiring) a reboot on the switch sorted it.

Cheers for thr responses guys, although none of the suggestions worked. I think itll be easiest to get a new NIC.
