I have just received my 24" iMac and there seem to be come problems with the Airport. Sometimes when I try to join my network, I am told there was an 'error joining the network. Other times it works just fine. If also find that if I keep turning Airport off and then selecting the network, eventually it will connect. Its annoying because every time I restart the computer or wake it from sleep, the problem arises again. I have a Netgear router (DG834PN) and have had no trouble with it before. There are 6 other Macs in our house and this is the only machine to have trouble. Might also be worth mentioning that I have full wireless signal strength. Anyone have any idea what the problem might be?
