Ethernet Controller issue

About a week ago, I reformatted Windows and reinstalled Vista Home. The network; both the wireless and local was working fine until yesterday. I'm getting limited access on the ethernet card. 169 IP address. Cant renew. I tried, updating the driver which is: Marvell Yukon 88E8038 PCI-E Fast Ethernet Controller. That did nothing. I tried to reset the winsock, that did nothing. I tried disabling and enabling and uninstalling and reinstalling the driver, still nothing. I shut off the Microsoft live one care firewall, that did nothing. I downloaded a Yukon monitor tool, and it shows the cable and card to be working properly. There are no IRQ conflicts. The wireless card works fine and I'm using the internet fine. I tried the basics as well. Different cable, reset the router. Not a router issue, bc there are 4 other computers on the router wired, and they are fine. Please help.

Sorry forgot to mention, it's a Gateway Laptop

Helllooo??? Anybody?

No one has a suggestion or tips?

Probably entirely off-base, but the only thing I can throw in is: have you tried putting the card into another PCI slot? I've just had one burn out on me; even after sticking the new card in, I couldn't go online (despite the device appearing in Device Manager) until I swapped slots.

Other than that, I got nothin'.

Sorry nothing here either.
