Ethernet card has no physical address ?

I am trying to get connected to the net via an onboard ethernet card. ( SiS 900-Based PCI Fast Ethernet Adap
ter) It did work within last 2 months. The cable modem works via USB. TO get a network up and running I need it to work via Ethernet.
I have tried removing the driver and reinstalling it.
XP detects when the ethernet cable is unplugged, or if the device on the other end loses power.

I think i have isolated the problem, but have no idea how to solve it.

please help

here is result of ipconfig

Hello All
Panic over .... i'm sorry for posing what i thought was a tough question.
It was easily resolved in the end :-/
I downloaded a new driver from www.driverguide.com
and Hey Presto !!!
I assume my existing driver had become corrupt.
Thanks to all of those that looked, and to ClintN for his prompt reply.

feel like a bit of a time waster now , but after being at it for 2 days and on the phone to my cable provider for an hour, I was at my wits end.
anyway in case anyone else should happen across this thread .....
the SiS PCI Lan Driver ver 1.16 for SiS Lan Adapter did it for me :-)
