Re: Packet Loss has Comcast Techs stummped.

Same issue here. I live in Denver, CO. New Construction house. Moved in last month. HSI only install. Same modem as you. Blast service 50 down/10 up. Drop comes into house, the tech said it was coming in too hot, so he had to put it on a splitter. (Just two way). The connection has been solid for about a month, then all of the sudden i have been experiencing the same "Packet Loss" that you have.. I use skype alot for my work phone calls, and casual gaming as well.. It's starting to get spotty.. I did the same thing as you, I called comcast and they did a "Modem Reset" or "Line Refresh".. But that didn't seem to help the problem. I've tried all the typical troubleshooting techniques.. This is my "Ping -t" to google.com as of right now.. Directly plugged into the modem...

I'm getting the impression that this is comcasts problem. Or, my modem could be going out.. Which would surprise me cause it's only a year old..
