I've had a little look for a fix but I just can't find a working solution. Whenever I turn my iMac on or wake it from sleep it will never connect to my wifi network, gives a "timeout error". It'll then say it can't find my any of my networks and if I'd like to join my network (isn't remembering my network?). It takes about 5 minutes to connect. I just have to keep clicking connect and hope for the best. Tiger didn't do this and my PowerBook on Leopard, next to my iMac, connects right away. It's a 2ghz C2D iMac from 2006. Plastic one.
