![]() The ISP should inspect and fix cables outside, since they get easily damaged by rain,fire, animals, construction, and even techniciants, etc)Įvery time I have see a T3 messages with "No Ranging Response received - T3 time-out CM-MAC=00:00:00:00:00:00 CMTS-MAC=00:00:00:00:00:00 CM-QOS=1.0 CM-VER=3.1" I would replace the cables inside the home. Since you do no have splitters, look for loose or bad cables. Squirells have nested and partially chewed some cables. He traced the problem to a box two blocks away.

I have replaced my modem, I have replaced my router, I have replaced cables, I have NO splitters on my cable line in. You would be a legend to my family and me forever. If anyone has any information on how to get this straightened out that would be incredible.
