Hey,
seems like the guy from topic "Lag Bug" has the same problem, but the topic seems dead without any solution.
The problem:
I can see my friend connect, we start the map and he doesn't move and no chat messages come from him. Although on his screen, he is moving, he sees me moving and he can chat.
The exe is allowed in his firewall, it's not his antivirus, redownload does nothing, repairing the client does nothing and it is not the connection. We have the same provider (we also live in the same house), I'm currently using our wi-fi, which is slower and it is ok to me.
Wi-fi speed: ~3,5Mbps
Cable: ~10Mbps
It was told to me to write directly to Santa, but maybe someone has already got a solution? (plus he will probably come)
EDIT: Well, he connected to the same, SLOWER wi-fi site as me and we can play now ...
