Started Unicast Maintenance Ranging - No Response received - T3 time-out

I'm getting numerous modem issues per day. Can anybody tell me what I should look for? This is a Netgear modem.

Here is my log:

Hello. Do you have any splitters or signal amp on the cable line going to the modem? -Allan Cox Support Forums Moderator

I don't have any splitters. It's literally just a cable that comes into a bedroom and about 12 feet of length over to the closet. 

I have the modem hooked up to a router.

I replaced everything twice this year, because I couldn't get anything to work for a while.

I have a Netgear modem where this is happening to me as well. Two modems in two years with no change. Three technicians have been out. Splitters removed and all barrels on the coax cable replaced. They all said there is one line feeding three homes on our street. One of those lines has high ingress and could be backing into our line. The lines aren't marked so they couldn't find what house the ingress was coming from.

I am also interested in a solution.
