So I got my old computer hooked up to my TV and finally working and now I need to get internet to it so I can surf the X on my bigscreen. My main computer and router are upstairs, what do I need to get internet on my TV downstairs? Can I buy a second router, hook that up to the cable jack downstairs or will that not work? Can I get a wireless router upstairs and a cheapo USB dongle to recieve the signal downstairs? Is there an easier way (short of running an ethernet cable all the way downstairs)?
