I have my Airport Express G (with Itunes)in one room and in the kitchen,about 10 feet away,(direct line going through walls) I'm sitting with m Imac G5 and a Macbook (2007 model) and the signal is very weak on the IMac,yet my Macbook gets a very strong signal in the same location at the same time. Why would that be? I've had problems with reception strength using my Imac for as long as I've owned it and tried many ways to solve this but see the problem may not have been with the weak signal or interference but maybe at the receiving end (since the Macbook has no problems)?
Is there a weaker antenna in the Imac?
