I've had significant problems in 2 flavors (SuSE and Redhat/Fedora) of
Linux with the Asus nVidia on-board hardware.
Go into the bios. Disable the on-board ethernet hardware. Use the PCI
card. Should work fine from there. While you're at it, disable the
sound and other unneeded periperals.
Windows has the info on the Asus/nVidia API, which isn't readily or
frequently released to the Linux world.

On window$98 I always get the link. Then if I make a soft reboot, I keep it, and I can get my adsl connection to the internet.
