I just got a new Imac and I am trying to connect wirelessly to the internet. I have a new wireless router and my airport icon (top right of the screen) shows full signal strength. The problem is that safari and explorer both do not want to get on the internet. I keep getting server not available. What could the problem be. Sometimes Safari will get through and connect, but most of the time it won't. I am new to this, and mac support hasn't helped a lot. Any help would be very much appreciated. Thanks, Matt
