jhookt,
I've been having this same problem, let me take you through it.
First off charter sucks. There's always a problem with them. I've got comcast though and they're messing up here too.
I'd post my pingplotter results, but they look the same as yours. Only real difference is my router is out of the loop now so I'm getting packet loss at #1.
The comcast guys were here yesterday (and the day before), and we think we've tracked the problem to the box outside the building that goes to the street. Unfortunately that means a whole new set of bureaucratic nightmares.
I haven't been experiencing any bandwidth problems that are noticeable, but when I get in game and close on someone's six the hickup makes them bounce literally everywhere. No one in the building has said anything, but it seems to be affecting everyone. It's only down at the finer points of connectivity that you see the problem, and without running something like pingplotter most people won't even believe it's an issue.
Tech support on the phone tried to run a "ping" command at text prompt to my machine and it told them there was no packet loss. I told them use "tracert" and you'll see the corresponding hop time out. (syntax: "ping IP" or "ping URL", "tracert IP" or "tracert URL", use start>run>cmd to get a prompt window open easily). Tracert is a less informative equivalent to pingplotter, basically. You're obviously seeing the problem yourself on pingplotter. Don't let them tell you its fine, because they probably will try.
When the tech figured out that it wasn't the lines going to my modem, he hooked something fancy up to the box outside and momentarily saw a hickup, but then nothing. Data on my machine the whole time indicated the problem persisted. He guesses that his machine began to auto correct as a matter of its software programing to get an accurate signal.
I am positive it is not my machine, as my router comes through fine (as does yours) and I have no packet loss when I plot a route from my school connection (on this machine).
In AH at the server board you can open up the ping details for each server with the button. Do this and watch carefully. You might see the packet loss count increment to one briefly, then go back to zero as the packet gets through. That's what I saw at least. Pingplotter seems to be throwing this just as an error, whereas AH seems to find just the hickup. Skuzzy may be able to call me off base on this, but these are just my observations. This hickup is what manifests itself in the game to make me waste a lot of bullets (and screw up landing last Wed on CV during snapshot).
My solution? I'm going to rally the other internet users in my building to get on comcast about sending the linemen out. The techs were awesome, but they said not to take crap from the office. Said it might take a while to convince them to send the guy with the meter to sit there to actually see the problem, which we had just seen ourselves.
Hope this helps. Email me if you like.
I'll keep you posted.
