I'm running a PC using a wireless dongle and all is fine, the main computer downstairs does not have an internet connection. Any ideas what could be wrong?? Thanks...
Well, For starters, Do you have a Wireless Network Adapter for the computer downstairs? And if you do, Have you installed all necessary drivers that came with the adapter?
If yes to both of those, And you cant detect the wireless network - It is very possible that the signal is not making it from your router to the location of your other computer.
