I've recently had a new XB7 sent to me because I was experiencing the exact same issue on the XB6. Throughout the day, I will lose service every 30-80 minutes, sometimes every 20. Equipment doesn't seem to be the issue, and this issue has been already present for approximately 4 weeks. Comcast has already issued a credit due to the recurring issue, but I want my service to work properly instead. They have sent "outside techs", some agents say they noticed a signal leak, however no one seems to come out to resolve the issue...at all. I live in a apartment building and the cable that goes from the back of the building, which was replaced 2 years ago, goes to a signal amplifier installed by the tech when they dropped the new coax, from there to the cable modem, no other splitters in between. Below are my signal levels, hoping someone can help. Thanks in advance.
