Dropouts after midnight daily

Anonymous
Not applicable

Been having dropouts for the past couple of days after midnight.
Checked the modem noticed upstream issues.
Which I believe is indictive of a mainline issue.
Not sure where the fault lies.

Unfortunately support via customer services hasn't yielded much help.
They just said they would monitor it and let techs know.

Found a newer VM cable upstairs with 3db attenuator attached.
Levels are higher than a 6db attenuator but more stable.
So maybe the cable that was in use before was a bit screwed who knows.
As I say once I get a better attenuator delivered.

Can find out if the line is too hot or it's a bad modem.
Ah fun times😂

And we're back to this when I do a line check.

Looks like there’s an intermittent signal issue in your area

Modem is very broken.
It thinks it's 1970😂
