Yep this happens to me too ever since 2.38. I've posted in all related threads about it and even submitted a bug report, which was moved to the "technical issues" forum. My record so far is 8 dc's in a single match, and it does seem a bit better last days, but I still dc at least once per match. In my case it's very frustrating since I play on ps3 and loading times are eternal, which makes me lose a lot of time between the dc and coming back in.
