When you say that "- The second tech replaced the coax cable that runs to my modem and said all signals look ok outside in the green box.", do you mean the cable from the wall plate to the modem? You would know if the cable outside had been replaced. If you have the standard green cable box on your yard or nearby, replacing that cable means digging in or across your yard to bury a new cable. So, it sounds like that has not been done. There was another case very similiar to yours this week.

I'm interested in seeing if there is a drop in signal power when you refresh that page. If the signal power stays up and the modem shows online, that would mean to me that the problem is upstream. All the modem probably cares about is the signal power that is present, presumably from the data carriers. Maybe it doesn't know, understand or care whether or not there is any data on the carrier frequencies. If the power drops, that would indicate a possible cable or connector issue, which wouldn't surprise me.
