Constant loss of service

Wyrdo
Tuning in

Morning,

Figured I'd post here as I've been having constant issues since last Sunday (26/3) that are getting progressively worse.

I'm constantly having to reboot my hub to restore service, it can last minutes or a few hours but is happening multiple times per day.

I'll past the status from my hub and the monitor graph in the hope that someone can help.

You need an engineer to fix the line.

Many of the Downstream channels have a Power level (dBmV) below -7 which is below the good service range.
