I have a Macbook pro 17inch running 5.2, I have noticed when on the very edge of a wireless reception my 14 Month old laptop will not pick up the signal and often not even stay connected, when my g3 powerbook(os 4.9) will pick it up. Ok so maybe its a Lepard issue, well my girlfriend's ibook g4 (os 5.2) also will pick it up ok. So ive tried other base stations now with similar results. Does the macbook pro 17inch just have crappy reception or is it possible I have a faulty card. I was going to open it up to see if the connection to the card from the antenna is ok but its not as easy as it is on the pismo or ibook and will void my warranty. Any ideas?
