This is the net book I upgraded to windows 7 ultimate 32-bit. Asus Eee PC 900HD - ProductWiki unbiased product reviews
It shows available networks, but when I try to connect it says "windows was unable to connect to network". I tried using Windows network diagnostics to try and fix it, but it didn't work. I also tried resetting my router and removing the password from my network, but those didn't work either.
I am able to connect with an Ethernet cord though.
