Hi there, I have got a Sony Vaio laptop with Windows Vista home edition and Norton internet security package. The active firewall is norton's. My pc is connect to a wireless network. I can browse the internet ok, but sometimes it seems that something is preventing some network traffic. I think that the problem is either the network profile Windows as assigned to the network or the norton internet suite. Anyone can tell me how I can change the network profile (home, office and public) of my network? Or delete the existing one to create a brand new one? Regards, D.
