So my fiance has had some problems with his 360 lately. Last few days it only connects to the internet when it feels like it. At least that's what it seems like. We've switched out the ethernet cord, reset the modem plenty of times, called comcast for them to refresh the signal, and turned it off and back on again. My 360 connects with no issue but his takes a few tries. Once it took a couple of hours. Any ideas as to what might be causing the problem and any suggestions on how to make it connect easier?
