Also, power cycle your modem and/or router and connect with a cable rather than wirelessly if possible.

There is not so many game servers in my country.And i must play on euro servers because of this.I dont have same problem past year.Can you help me?
If you've power cycled your router. rig, and ensured there are no network issues then you need to start looking towards the game/rig.
Ensure you're not running unnecessary software, note security software may interfere with connectivity.
Ensure PunkBuster is updated as a first step, see this.
Uninstall and reinstall the web plugin.
Uninstall and reinstall the game.
(Try the above until it's resolved. If none of the above resolves the issue then your next point of call may be a Game Advisor).
