I bought 4 of these to hook up 3 TVs in different rooms. Only the TV closest to my router on the same circuit had a stable connection. The rest drove everyone crazy because Netflix was only available occasionally. Fixing these problems is PITA, which involves running back and forth looking at LEDs that take forever to tell success or failure. I'll drop them and try ethernet over coax instead.
