I'm not too sure really when this happen, i'm going to guess it happen sometime after I restarted my office computer, to update iTunes. I noticed something was wrong after I tried connecting to Netflix on my TV (it said that the connection failed), then tried getting on the internet on my laptop (connection failed), lastly, my iPod (couldn't connect to network). I'm really confused about what's going on with the Wifi, and why its only working on the main computer, that it is hooked up to. Please help.
