Hmmm.. It appears as though AT&T (formerly Southwestern Bell in my area) may be blocking CoH traffic which would explain the "rubberbanding" issues that I'm experiencing.

Here's a sample Traceroute from the CoH netinfo support tool:

I've hidden my IP address in the above trace for privacy reasons, but you can see that all of the network packets are getting dropped at 70.143.229.30 which is registered to "AT&T Internet Services".

If you haven't already done so, I would encourage you to download the CoH netinfo tool from ftp://ftp.coh.com/support_tool/ and run it. Take a look at the logs and verify that your ports are open and be sure that the "Path Ping / Trace Route Tests" show 0 lost packets.

If you see any packets getting dropped, look up the IP address to see who owns it. A good website for looking these up is http://ip-lookup.net

I've submitted a ticket to NCSoft Support, but I may have to call my ISP to resolve this one. (ARGH!)

I've set pretty much everything back to "default" values in the COH audit/video settings.

After not playing CoH for 2+ years, I decided to get back into it this weekend. Right off the bat, I encountered the "rubberbanding" issue that is described in this thread. The issue is pretty severe, occurring every 3-4 seconds, which makes the game pretty much unplayable. I also noticed that the NPC and background animations are all accellerated 2 to 3 times faster than what they should be. I'm pretty certain that it doesn't have anything to do with my internet connection because I don't have any problems playing other MMORPG games (WoW, etc) and it's a high speed connection (6 MB) but I ran the /netgraph command just to check. It shows that my receive speed is 650-700 and I don't have any lost packets. I'm getting 20-30 FPS on the video which rules out a framerate issue.

I'm at a loss for what to do. Does this sound like it's a SYNC issue to you guys? Do you have any other suggestions?
