Multiplayer Network Dropping


Hey, just wondering if someone can help me out with a multiplayer network issue. Every time I log into a server, I am able to create a character, and begin the game, but as soon as I launch to space, my network connection begins to drop. It has happened on a number of servers, and does the same thing every time. I have tried turning off my firewall, I've tried putting my ip in the DMZ of my router, all with the same results. I'm on cable internet, so connection speed shouldn't be an issue.

Any suggestions would be very much appreciated. Thanks.
