I've searched around and realize there are issues with Airport on the Macbook, but I just got a refurb Macbook today and Airport seems to not work at all. Scanning for networks doesn't turn anything up - not my network (from Time Capsule) or any of the neighbors that I know are in range (and that my iPhone and PowerMac both can detect). Did I get a bad Mac? Is there some obscure setting I'm missing? I connected with ethernet and ran all updates - running 10.5.4 Thanks in advance!
