I have a Ti Powerbook 500, running OS 10.4.11, using the original Airport card, with Airport Update 2005-001. It is having trouble logging onto my wifi network with a WPA Personal level security code that works great with all of my other devices. It see's the network, gives me the option to log in, but says it can't connect. Any advice/hints? I searched the Apple Support pages for a new Airport update, but no joy there. Have I missed an update somewhere? I've just changed the wifi router, I hadn't done anything differently to the Mac. The Mac can connect to the network with an unsecured setting on the wifi device.
