I've just moved into my aunty's place and I want to connect to the wireless network she has (to connect to the internet). AirPort recognises the network, but when I try to connect to it I get this message: "There was an error connecting to the AirPort network wlan". She uses her windows laptop on it all the time and I can connect to the internet via the ethernet cable but I'd really like the wireless to work. Is there something I have to do in the modem/router setup to allow me to connect? Any help would be greatly appreciated.
