|IF the PC is hard wired to the router, it works fine, I can not see the wireless router when viewing wireless netwokrs|
Your question isn't really clear. When you say "can't see the wireless router" do you mean, you can't connect to the router once you've connected to the wireless network?
Or, do you mean you can't see the wireless network?
If the latter, can you still connect to the wireless network even though you can't see the SSID?
