ERROR Game disconnected: your connection to the server timed out.

Same problem for me, exept it happens every game and my leveling progress for that match is erased, (happened to me in bf3 as well) 

i also get crazy lag/ping spikes, but only on BF games, all other games are fine

it took me 120 hours to reach level 40 because of this.  Dice please fix this, i won't be buying bf4 if i can't play a whole match
