I'm with Leslie, Do everything you can to encourage the doc to finish the note in the room. I put inexpensive dell desktops in the rooms, WIN 7, with 4GB ram for about 400.00 per work station.
Wired is the way to go. Ever considered the electrical wire network which works through your outlets? They are faster than wireless.
