It's not 100% certain, but I will post this information for the record - if anyone else is experiencing similar problem.
After I updated the firmware of AC-68P from 386.7.2 to 386.9, I began to experience sporadic disconnects in the game "World of Tanks". The game would disconnect in the middle of the battle, then reconnect and continue. In all times the ping of the game server was no more than 20ms, and it never was a problem to reconnect immediately. This never happened before in many years of playing.
After I downgraded back to 386.7.2 because of another problem, this problem disappeared. This also involved reset to factory settings, which is why I'm not 100% sure.
