Was working fine with aol. Sony Vaio has a network card installed. As I can access the network on other devices must be a setting\fault somewhere on Sony laptop. I read something about each devices has to have a different ip address? I have\had a home network with a pc (haven't touched this as yet)and a laptop, also logged on to the wireless with my itouch.
