Server keeps disconnecting

Game hanged. Cannot log out. Stuck in middle of combat.
Server disconnects. Help!
Unable to “petition also”.

Same dc`s there, not so often, but hard. As i see the problems in server right before AoC servers: GAME-HOSTIN.ear2.Newark1.Level3… ( On this server dropped around 30-50% packets. But not all time. I have started this damned lags around 3 month ago. Is fancom can do something with them?
