I don't know if this info helps. I have the same problem with my aspire 5110. When I'm close to the router there is no problem to find or connect to my network. But when I try and connect from the next room the problem starts. Sometimes I see the network (with full signal strength) but cant connect but most of the time no networks comes upp all. Running Lubuntu 11.04 2.6.38-8-generic
