My father is in a small personal care home (less than 45 people). The building is 3 floors (basement, 1 and 2) and less than 120 feet long by 60 wide. Its standard hotel construction. They currently have a Netgear 3500 located in the office located in the center of the first floor. Comcast service is extreme 50. There are only 6 devices on the network - an office PC, Verizon network extender (tower issues not building construction) and my fathers devices (Ooma, Samsung Skype TV, Blue-ray player, and Google TV). Occasionally, there is a smart phone attached. My fathers room is at the end of the second floor. Because the wireless is so bad (InSSIDer says -95 dbm), I temporarily set him up with powerline adapters but the link connection is pretty bad (3mb) due to the business grade electrical system. My ultimate goal is an N66/AC66 on the second floor as an AP with possibly another one in his room as a bridge. As other residents are looking at this, I would expect more to use this. Was thinking of starting off with the N56 in the office for aesthetics and the 66 heat issue since its on a paper cluttered desk. Any Suggestions?
