So I just finished building my new desktop: i7 3700k 3.5 GHZ GTX 550ti 8 gb Ram So I am not worried in any means of my computers ability to play this game. Here is all the information though: So this past weekend I was at my house playing DayZ just fine. I played over multiple different servers with little to no problems. Then I get back to campus. Yes, I live in a dorm. No, my dorms are not jackwads; they do not restrict internet usage (some what). So I get on campus and start up DayZ. Holy poo, this is bad. My pind is hovering around 1300ms or 2300ms. Sometimes I am lucky and it drops down to 800ms. So I call my housing dept. They say that they don't keep ping packets so the Ping I see is "artificially" high and I should be fine. Well the servers don't care and won't even let me in. Except one: Laughing Man's Server #3. This server I have a character on and I never have over 50ms. I could hop on it right now, just don't ask me to do that for any other server. I disabled my Windows Firewall, but sadly, it was on when I was playing at home. The housing dept says it isn't the ports and I should just keep retrying to join, but after the tenth time I usually give up. No I do not have direct access to a 'modem.' Any suggestions as to why this single server works, and not others? Thanks in advance.
