I am going to my upgrade my Series 3 to a Premiere in our master bedroom. We don't have network wired to the room so I have been using the old wireless adapter which gets a signal strength of 30 to 45% on average. To get the best performance, do you think I should purchase Tivo's wireless N adapter? I guess you can buy these things which plug into outlets for network connectivity? Or should I go through the trouble of having a professional installer run a physical network line which likely won't be easy? Please let me know. Thanks.
