The Shaw guy is done, he changed a bunch of connectors inside.
He had an app on his phone that shows a number indicating
"levels" for the phone adapter and cable modem, apparently
the signal down was fine but the number going up was "too
high". (So it's not signal strength...maybe an inverse of signal
Apparently what brought the levels back into the normal range
was when he changed one of the outside connectors where
the run from the lane meets the cable running into the building.
(Which is weird because they were changed last November
when I got the phone adapter.)
After that the levels were in the appropriate range. (He said
they have to be not too high, not too low.)
So hopefully that fixes it and the server should be back online
