My friend's iBook is able to log onto my Apple base station, and her parents Netgear base station. However, her own base station won't allow her to connect. It can find the base station, but it can't download or upload anything, surf any sites, etc. My PowerBook and my friend's fianc�s computers are able to get onto the network just fine, the settings are the same as my PowerBook, and the AirPort and system software is updated to the latest versions. (Mac OS X Client v.10.3.2, AirPort software 3.3), and yet it still doesn't work. What could be the problem?
