So here's another image. Not as bad as the first two but still not very good.

I must admit I'm overwhelmed by all the information, but it still does appear that the first hop is the predominant problem. I'm still trying to get handle on what to do with this information. I have to be very well prepared for that front-line Comcast rep who wil be fixated on telling me to recycle my cable modem and not much else.

I hope this information helps you further. Thanks for the assistance, Pete!
