I have a big problem with my girlfriend's netbook (asus eeepc 1008). It doesn't see any wifi network. I'm explaining the problem:

The pc use windows 7 starter
The wifi card is activate, I update drivers. It's a Atheros AR9285 wireless network adapter.
The ethernet card is activate too, when I plug a ethernet cable, the netbook can go on the web.

When I want to show all wifi network, I see nothing. When I want to add manually a wifi network, I get: "An error is occurred" (very helpful this message ^^)

I can't ping the gateway of my personal network.

My macbook can connect it on the wifi network, so I don't think it's a gateway problem.

I don't see how resolve this problem.

Thanks for your help
