Today I brought an Apple Airport Express for the PC in my front bedroom to connect wirelessly to my Airport Extreme Base Station for much better connection quality but I have not been successful with it and the instructions from Apple are very sorely lacking in any help with the matter.
Airport Extreme Base Station connects to my cable motorola modem via ethernet.
Airport Express sits in the wall doing nothing at the moment.
My iMac uses the ethernet to connect to the extreme
My Macbook uses it's airport to connect to the extreme wirelessly
My PC uses a netgear wirless USB 2.0 adapter (WG111) to connect to the express with no success.
The mac side is fine but the PC side is not I have tried different methods with no success I just loose connection to the express and the only way to get it back is to reset it back to default settings.
Please Help
