First off, I am sure to be VERY computer challenged compared to most of you. I apologize for that in advance. Here is the problem. We have been a PC based family for years and years. We just started to go Mac. My son got an iMac and my wife an iTouch. We have a wireless internet network in the house. The wireless is set up w/ Lynksis (I don't know if that makes a difference for my question.) I have connected to this network with more than one computer and more than one laptop. I have never had a problem. My son's iMac (airport) picks up the network and seems to be connected but can't do any more. It cannot connect to the internet. My wife's iTouch is the same. Our PC based computer and laptop will connect though. My son's iMac DOES, however, occasionally connect to the internet using the neighbors VERY weak signal. My wife's iTouch will connect on other networks (i.e. Panera Bread's) so I kno that works as well. PLEASE, PLEASE HELP ME!!!!!! I am going crazy!!!
