Have 2, 55" HDTVs (Vizio & LG), and 1, 27" HDTV (Vizio). All wireless, with Linksys EA4500 N900. When streaming, the large TVs rarely buffer, but the new, smaller TV buffers almost all the time, even with the other TVs turned off. Even the computer (cable with TWC) will only have Outlook open and nothing else running. Why constant buffering issues only with the 1 TV?
