Our ROKU 3 unit keeps dropping the internet connection, despite being ethernet wired. All other devices do not lose the Internet connection - only the ROKU player. Have changed cables, have re-booted multiple times, have unplugged/re-plugged, have rebooted the router repeatedly - no changes. BUT - if I unplug the ROKU for an hour and restart it - peachy keen - for a while. Then it drops the Internet again. What I started to notice was how warm the unit gets, despite being on a raised table with nothing around it. But the hottest part of the unit is the bottom. So what the hell is up with that? Does the unit need a cooling fan or something, or is it a defective unit? I have contacted ROKU support several times, and they've been useless - "Have you re-booted, have you done - and yes, I have done all the things they tell me to do, and they just keep saying the same things. As though their support guy is sitting in a little room with no connection to reality and speaking from the same page their FAQ is posted on. Does ANYBODY else have a clue about this?
