When I click "Change Server" in the menu, the game starts searching for all available server. It uses a lot of my bandwith, a lot.. (sometimes I don't see any servers at all and I have to restart my game)

All other programs I run, like Skype and Teamspeak starts lagging heavily and freezes or times out due to no connection.

When I join a server, I get heavy lag, high ping, enormous desync for about 2-6 minutes then all goes back to normal.. low ping a 0 desync.

Tried uninstalling, updating game, playing without my router, joining low-ping servers with no result. {F30308} {F30309}
