I worked with Comcast last night and hopefully sorted out the packet loss problem. Here is a fresh UO trace.

I did play a couple of Ones Eliminator games this morning to test. I did not experience any network lag, but unfortunately the loss of control of my skater persisted. I played a few of drop-in NHL 20 games last night and never lost control of my skater.
In conclusion, while I was experiencing packet loss which did negatively impact the online experience of the game, it does not appear to be related to the loss of control of my skater.
Next step, I am going to switch to a different controller and see if that changes anything. Throughout this whole process I have not tried a different input device. The controller I have been using currently does not appear to have any problems as I played a few NHL 20 games online last night without trouble. In talking with some of my friends they have not had this problem in 21 and can see me drifting in games. I am only using the 1st party wireless controllers from MS. I have 4, so I will try one of the others and see what happens.
