At work I just received a iBook 500mhz running OS 10.3 and I installed an airport card. The range of the card is only about 10', if I sit by my desk top I have no problems. I also have a G4 iBook with an airport extreme card and I get about 100' to 150'. I rechecked the airport card about 2 or 3 times and everything seems to be installed fine. Does anybody have any ideas?
