My friend has a Macbook and cannot connect to a WEP wireless network. PC users in the same house have no problem and even myself on my trusty iBook G4 have no issue connecting to the network (though I am using leopard). After clicking on the network, it requests the WEP password, entered password correctly and rebooted AND cleared any wireless from keychain... but then always displays the error: "There was an error joining the AirPort network "<SSID>". I checked for any updates using an ethernet connection but there weren't any. The router is a D-link and claims Apple compatibility for tiger. Any ideas?
