I just bought a 24" iMac with Leopard and have enjoyed it very much. However after the 1.3 update, the wireless has stopped working. It times out every time trying to connect to my home network. My home network has WPA security, however under Windows Vista it can connect to the wireless without a problem. Anybody else having this problem? I'm really sick of wiring a 25' cable across the room to my beautiful mac.
