Acer Aspire lost connectivity over nvidia networking contoller

My new Acer was working fine for the first three days running Vista Premium.
Then poof, the network controller would no longer connect. Now the network
light on the machine stays on solid. I've tried uninstalling and
reinstalling the driver and even did a complete restore to the factory image
and still I can't connect. The only related thing I have seen is some nvidea
drivera were pushed down via WU. But the factory re-image should have
eliminated that as an issue. Other machine plugged into the same net cable
work fine.

Any ideas?

IPconfig returns this:
