My onboard ethernet port of my motherboard "gave up the ghost" last week and I purchased a new Swann PCI ethernet card.
It uses the infineon AN938B chip.

The onboard ethernet port is disabled in BIOS.

However I can't get it to communicate at 100mpbs to my router only 10mbps.

If I select either "Autosense" or "100 TX Dual" in the preferences I get a random blinking of the lan led on the router (with no connection to the internet) , but if I select "10 TX Dual" in the preferences then I get a solid connection and no trouble with the internet.

I have changed the cable and which port I connect to on the router to no avail. I can connect a laptop and a xbox to the router and have no trouble with the internet.

I have the latest driver for the card from the manufacturers website.

I am running a P4 system using Windows XP SP2 with the latest updates.

This is driving me nuts.

Motherboard should be absolutely fine with a 10/100 card at 100.

Have you tried removing the card and all drivers, trying in a different PCI slot and reinstalling?

Have you tried the card in another PC?

If so, then that leaves a dodgy card and/or drivers.

For the cost of a new card you may find it easier (and more cost effective) to get a new one.

If you do go down this route and suffer the same problems, then its a fault on the motherboard or an unknown compatibility problem (by a process of elimination).
