Try disabling your firewall temporally , set the IP settings to DHCP (automatic), disconnect & reconnect and see what happens....
Basically what is happing here is that you computer isn't recieving settings from the server (either it's caused by a setting in the firewall, a virus, or your router / modem is broken)
My daughter's computer is now non internet functioning.
I need a fix so she can use the internet.
I thought I could click on 'Unidentified' and change it to Home, but no I can't.
So help as this is not my forte.
Thanks in advanced Lee
