Hi, I recently got an ibook 1ghz g4 12". I'm having some difficulties with the AirPort card. I do get a signal when I'm at places with a wifi router, but it is always a weak signal (iStumbler shows about 21, on average). Over at an apartment with the ibook right next to a dell laptop, the dell's wireless is fast but the ibook drops a lot of packets and has a weak signal. Looking at the AirPort card, the antenna jack looks like it is connected fine, though I haven't tried unplugging and reconnecting. Any ideas? Other than the airport card, it seems to work fine. Hope I don't have to have it shipped for warrenty (and risk having more troubles, losing data on harddrive, etc, etc).
