I realize that this isn't an official support forum, but I thought that it couldn't hurt to get any ideas on the problem I'm having. Basically, I ran several traceroutes, pingtests, and noticed that there's a couple cox owned routers where my connection jumps up in latency once it reaches it during 'peak' hours. These hops look to be required in order to route my connection out of state (I checked and they're in Atlanta). I've contacted Level 2 tech support and am awaiting word on any suggestions they have. If they are unable to fix the issue, I'm set on canceling my service; note that I've been a customer for less than a week. I don't mess around when it comes to internet problems on their end.

I've used this site before to get help from cox representatives, but I'm not getting much of a response this time.
Since this is likely some kind of congested node issue (which still shouldn't happen), I was wondering what other things I could test myself while they address it. The only thing I can think of is trying out some other docsis 3.0 cable modems or maybe seeing if the Ultimate tier changes anything (currently on Premier). I very much doubt these will solve anything though given the nature of the problem.
I have a Motorola 6141 modem straight out of the box being used. My ticket number is #1538941.
