I never have any problems connecting to relatively distant AP's. Maybe the reviewed unit had a bad WIFI antenna connection (since he/she had trouble connecting to all networks).
I was worried about that issue. Hopefully it is just a bad review unit (oh all the faults in the world it had to be a bad review unit). Hopefully whatever the problem is it is just a simple one.
I haven't had any problems connecting to my router at home or when connecting via a peer-to-peer network to my laptop at work... In fact, I was amazed that I could stay connected to my laptop after walking down the hall to the conference room.
I have noticed that it works better if I connect while close to the laptop and then go to the conference room. I tried waiting until I was in the conference room and it would not connect.
