It sounds either like you have connection issues (ISP or cableing) or you are going onto very distant higher ping to you servers.
Our server is in Dallas.
On the disconnect issue; my connection is not slow, I have a fast system, this system stayed connected with the last patch, my average ping to my clan’s server is 70ms, it happens 90% of the time and only between map changes, it happens to quite a few members on the server and most importantly I can stay connected to other online games with no issues.
I believe it has something to do with the anti-cheat, almost like it disconnects you if something does not respond within an allocated time frame which is not long enough.
I am not the only one with this problem there are quite a few people playing on our server that have it.
I will play a couple more servers and see if it continues to happen and I will report back.
Thanks for the suggestions Roco.
