Packet Loss with 'Ultimate Internet'

I recently got 'Ultimate Internet' which is the best you guys have. It's really fast with surfing/downloading/uploading/etc.

The only thing is when I go in-game, whether it be Team Fortress 2/Left 4 Dead/Call of Duty/etc, I'll have low ping (which is great) but I'll get a consistent freeze/stutter/time-warp skip...frequently. Like, I can run in a line for 6 seconds, then freeze/skip for a second, run in a line, then another freeze/skip after 6 seconds.

I've got a SURFboard 6180 DOCSIS 3.0 Cable Modem (no router/wireless). I've got a line running from the wall in my apartment to the modem and then an ethernet cord from the modem to my laptop.

My laptop specs:

Sager NP8662
Intel Core Duo T9900 3.07GHz
8 GB RAM
nVIDIA GeForce GTX 260M
Windows 7 - 64 Bit






I've talked with COX's Tech Support multiple times about it. Did the Live Chat twice and yesterday was on the phone with Tech Support over an hour and talked to 4 different people. And I actually just got done having a tech come out to my place to replace the line and the modem.....but I still have packet loss. I just don't get it.

When the tech was here today we went in the command prompt and did a ping test to yahoo.com and it came back with 4% packet loss. His reply was "Well 5% is the number that we consider unacceptable." That ticked me off because packet loss isn't the same all the time, especially with this Ultimate Internet it seems.

I previously had an Alltel Wireless Internet Card (although Version bought them). The internet wasn't that fast and my ping was always high. BUT...I never had this packet loss problem.

I've unplugged/unscrewed/rebooted/turned off firewalls/disabled wireless......nothing seems to help.

'Ultimate Internet' is supposed to tailor to "hardcore gamers" and right now, it's not. 

If anyone is knowledgeable about this, I would greatly appreciate some help because this is so *** frustrating.
