So here's my situation.....I live on two floors of a brick building. About a month ago, I received my new PowerBook and set up Airport Express downstairs. I get full signal anywhere downstairs but upstairs I receive only 1 reception bar and sometimes lose the signal altogether. I have done any number of things and for whatever reason I just cannot get a better signal upstairs. I realize that PBs do not get great reception due to the aluminum casing. And I realize that the brick building probably doesn't help. To be honest, I am done trying to figure out why the reception is poor upstairs. It works perfectly downstairs and I LOVE IT!!!!! So here's my question.....if I purchase and set up another AE upstairs will it be able to pick up the signal from downstairs and rebroadcast it? Will it be able to pick up the downstairs signal better than the PB currently does? I don't want to buy it just to have a strong signal between the upstairs AE and the PB but a poor signal between the upstairs AE and downstairs AE. I want to surf all over the apartment.
