Mandy I am having the same problems on my iBook and iMac both running 10.1.4
I am using an airport card an base station to access internet wirelessly and because of firewall issues with it, am unable to connect or search. When I hook my iBook up directly to the phone lines with a jack, ot works fine. So I was just seeing if you were using airport then we have a similar problem. If you fix the problem tell me...
