hi guys. think about this. the setup: _G5connected to a switch _Airport Extreme connected to a cable modem so here's the problem: i tried to convert from 128 bit WEP to the new (more secure?) WPA Personal, but i get the message: "Joining a WPA-protected network and making changes to a WPA-protected base station requires a WPA capable computer. This computer is not WPA capable. If you continue you will not be able to join the WPA-protected network or make changes to the WPA-protected base station." i do not have the time to reconfigure everything especially this time before christmas . so has anyone tried this? thanks and merry christmas to everybody.
