Is your "wireless" turned on or off? That may cause a conflict.

Have you tried Gateway's website? It's a little confusing to navigate, but all the drivers should be on there.

Another FANTASTIC website that should solve all your problems (if Gateway's can't) is www.notebookreview.com . Go to the Gateway section of the forums and there's more information than you'll ever need.

BTW, I have the same computer and I love it. Also have a 7811fx.
