The last 4 games I've been in, I've been disconnected from. Usually takes 5 minutes or so, then everything on the field starts walking in the same direction they were going before the d/c, so I've obviously lost connection to the server. I've done the telnet fix for Thomson routers, but it's recently started to happen again. No idea why.
Have you restarted your router since the telnet fix? It wipes it when you do and you have to re-apply it.
It's all saved, and I've set it so the reset button cannot reset anything back to factory settings unless I do it in Telnet. Also, there's no GAME(UDP) in Telnet-Connections-Bindlist anyway. Seems ok now though. Could just have some dodgy servers.
