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

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.
