My friend an I are both using plusnet for our ADSL. On Project Gotham 2 online I could not connect to a game he was already in and vise versa. It was as if we were preventing each other connecting. Working ok on all other users so far except him. One word people, FIREWALL!!! I am not sure if it is because he uses a fixed IP and I use DHCP but when revised my firewall I could connect to his game. He left his firewall config alone and he could not connect to mine. So if you have the same issue, review your settings. My router is a DG834G model netgear, his was a VIGOR.
