As titled/ I Have an airport extreme router - latest generation. I have a good many devices able to connect at full speed. SUrface pro 3 maxes connection speed at 866 but can't even stream native format mkv from plex to the surface pro 3 -- something a bunch of other devices can do even on the n band. So not only is the connection showing half possible connection speed possibility from five feet away, It's not getting anywhere near that bandwidth. struggling to maintain a 5MBps connection Speed on copies fluctuates greatly and it seems the adapter in this evice is incapable of maintaining connectivity properly. It's the latest in a long line of defective parts as far as i'm concerned but maybe someone here has an idea of how to get a connection that's stable - even if it showed connecting at 300 if it actually stayed at that speed it would be fine. Thanks for any assistance, I am very unfortunately stuck with this absolute pile of trash of a machine - so any help is greatly appreciated.
