On more than one occasion I have been know to purr the phrase "No fiddling" to our
Balding Avian Entity.
I have a suggestion. You could try powering off the
HG612 modem when you have finished using the connection to Internet for today and then power it back on during the morning daylight hours, tomorrow. Doing that may allow sufficient time for the
MSAN's line-card port, to which your line is connected, to "relax".
The choice is yours . . .
