I just purchased an Airport express for my beach house to get a wireless connection. I dont have internet in the house, but I have family who lives in the complex and I can just barely pick up their signal. Im trying to use the Airport Express to expand their network into mine. The whole building is cement, so its difficult to keep the signal and I barely have cell phone service inside. Also my MBP only picks up the Airport Express at random times. I cant update the settings on it because once it restarts the computer can't pick it up again. Any help would be greatly appreciated.
