since last night and today, i've been disconnected a lot from matches. there's an error code with bunch of numbers on it. i know its not my internet. anyone else having the same problem?

Happens to me occasionally, but not frequent enough that it has bothered me.

This was a huge issue in the beta.  They said to turn off the media server back then, so try that.  If it's not on, then maybe you're DLing a torrent or something, or there's to many WiFi devices on your network.  Those were the biggest issues for network problems in beta, dunno about now.

Well I never been kicked out, it only happens when I'm trying to join a game. As Meptron says I'm not bothered.
I'm more bothered that the site is not up, and in game stats don't relay your current standing.
