Constant Internet/TV dropouts Error messages on Netgear CM1150V

Help!  We have been having brief internet and TV outages.  They last a few seconds but happen 4-10 times a day. Wired internet (and wireless) as well as TV. My Netgear CM1150V shows Dynamic range error messages a "critical" unicast maintenace warning. We had been having them a few months ago and Comcast came out, determined we had a low signal and installed a new buried line to the house. This fixed things for about a month. It has been very diffcult to get any answer from Comcast this time around. They see the errors and reboot my modem, or do nothign at all.  Help!  Screenshots below...

Can't see your pics. Since you are a new poster, they need to be approved by a Forum Admin. That could take some time. In the interim, you could try hosting them at one of those free third-party pic hosting sites like Imgur or Photobucket and post the link to them here.

Or copy all of the text of the status page and paste it into the body of your next post here.
