Thanks, Pete! I contacted Comcast and was fortunate to speak with a customer service rep who seemed interested in my problem. The pingplotter data had a lot to do with convincing him that the problem was Comcast's and not my own. He gave me his direct email and phone number.

Comcast is (again!) sending out an "inside" tech to check out my computer for the obvious problems like cycling the cable modem and removing the router. Once the inside tech finds that there's nothing wrong on my end, then he calls for a "outside" line tech to come and visit. That won't be for at least a week. Unfortunately Comcast does not allow customers to go straight to the outside tech because I'm guessing they are most expensive. So on Monday I have to go through the charade of having them look at my computer and telling me what I already know.

The process is slow yes... but it is moving. My packet loss peaked out at 25% a few days ago. Today is a relatively light day of only 12% packet loss.

Thanks again for the assistance.. <img src="/forums/images/graemlins/grin.gif" alt="" />
