just installed new extreme card for my power mac g5 to connect to my new ap express station in hopes to use airtunes. Card installed fine. My ap express station, according to istumbler gets 40% 2feet away, 30% ten feet away in same room. My express station doesn't even show up if it is farther than ten feet from my comp. I tried changing channels with no results. Istumbler showed no other devices beside my router on a different channel. I checked the signal of ap express on my iPhone and it doesn't show up at the same distances as the computer mentioned above. I also tried moving it to different rooms with no luck. Is ap express this bad? I expected at least fifty to seventy feet or so. Is this a defective device or am I missing something here?
