can see network but can't connect to internet Vista Feb build

[nazrac]

Mb- ASUS nforce 4

build - vista feb build

problem- Using a netgear router and a dsl modem I can connect to the router and see the other computers on the network, but cannot connect to modem or the internet. The cd with my mb does not work under vista so I downloaded the alpha network drivers from nivida's website which worked for the dec build. I get an error on driver update for the bus enum but I got that error on the last build as well and it worked fine. After playing with it I can get the networking controller 2 to install successfully. When I launch IE it gets the ip address of the site I'm trying to connect to but never loads it. I also lose the driver update every time I reboot. Any ideas? I did disable ipv6connectivity. Thanks
