After a THIRD attempt at a fiber line install (3rd one being done by a field tech lead), everything finally seems to work properly (for now).
Tech showed up, seemed to know what he was doing. He said somehow all 9-10 of our coax lines (mostly tvs) are causing a lot of noise on the modem's line, and all of the previous 5-6 techs just replaced things at connection points since coax in the walls are rarely a problem like this. We'll either need to have all the coax lines replaced, or we're just going to swap the modem to a fiber one and have one fiber line installed, since it's immune to EMF noise and see if it fixes it. I think this was initially two compounding issues, a problem at the node that was fixed between 6/12 and 6/15, and also the noise in the house. Will post again at some point after either coax is replaced or fiber is installed, but might be multiple days til then.
fiber install scheduled for 10am-12pm wednesday, will post update after
What does that cost to run fiber in your home?
$125 for the one line for the modem, though tech said there’s a good chance we’ll have credit added to the account to make it effectively free
