I have been having intermittent internet outages going on for three weeks now. I called Comcast and had 3 techs come out over the past weeks. The first tech came when everything was working fine and said everything looked okay. The second tech came out with his supervisor and reported something wrong at the tap outside and called maintenance to come fix it, maintenance came but said everything looked fine. The 3rd tech came out and changed out the modem as well as some coaxial cables, he also mentioned that the connection at the tap was loose. He also spent sometime finding something that was causing interference inside the house...he suspected I had an amp installed but I don't. Despite all that's been done, I still have intermittent outages, I've posted my modem stars below. Sometimes power cycling the modem works and sometimes not. I am getting sick and tired of this. Also when my internet goes out my on demand service is inaccessible and some of my channels become pixelated but everything works fine when the internet comes back up.
*note* Weeks before the outages began, i did install an HDHomeRun prime tuner and new powerline between adapters, I have since disconnected these new devices and am still having the same problems. Also, I was able to connect to my modem as the shortage began and the upstream power jump up to 49 then 54 before completely disconnecting.
