Periodic Disconnection

Hello all,

Lately I've been having a very bizarre, yet incredibly frustrating and annoying issue with my connection in CoH. This issue started happening since I switched my ISP a few days ago.

Here's the problem I'm having:

Usually (not always) I keep getting disconnected with a typical Mapserver error. This happens periodically at semi-regular time intervals during the play session. However, it's not JUST a simple mapserver...

Every now and then, I suddenly can't send any information. I can move around just find. I can see people sending messages. I can receive tells. I see global channel messages. Enemies can attack me.

But I can't send anything! I can move on client, but the movement doesn't register! I can't activate powers. I can't send messages (to any channel). I can't even log out! Clicking Menu -> Quit -> Quit to Login Screen doesn't even do anything!

This goes on for several seconds until I eventually get a "Lost Connection to Mapserver" on my screen. THEN I can log-out and log-back in, and everything's okay, until it happens again...and again...and again...

I've recorded the times that this issue has happened during 4 play sessions. Here are the results (do you guys thing there even is a pattern?):

Session 1:
6:12 PM
7:40 PM
7:56 PM

Session 2:
10:51 PM
11:15 PM
11:55 PM
12:27 AM
12:51 AM

Session 3:
7:40 PM
7:55 PM
8:20 PM
9:15 PM

Session 4:
10:45 PM
11:16 PM
11:48 PM
12:20 AM
1: 41 AM (???)
1:56 AM

Also, I've monitored /netgraph 1 while playing, and when this happens, I simply get a few spikes of yellow bars. But my actual ping number doesn't change much, and when the "no-send" period begins (where I can't send any information to server), the "RETRANSMITED" value starts counting up to around 20 or so before I officially disconnect.

Has anyone ever had any issues like this? I wanna make sure the problem is with my ISP before giving them a call, since the issue doesn't happen with other games.

Please help. It's really driving me nuts. :(

Edit: Also, yes, I've tried resetting the router/modem several times, changed my dynamic IP, and re-configured the network several times. Didn't solve anything.

I decided to update this thread because I managed to fix the issue.

To anyone who is experiencing this sort of disconnection, please contact your ISP and ask them how you can enable DMZ, and what host IP you should use. My issue was with the DMZ setting in the new router. DMZ must be enabled for some ISPs to allow a smooth connection to the game.

Have fun!
