Hi!
Been a long time since I posted here! Been having an issue with my connection pretty much from when it was installed. It will intermittently start bouncing up and down - last night was particularly bad, with 26 interruptions in the space of an hour. Looking at the stats I think our DOCSIS 3.1 levels are out of spec and we have a fault - our PLC power is -15.5DBmV where I think the spec is like supposed to be -6 to +10DBmV. Full logs below! :

It would be best to phone in the fault and request an engineer visit to address the far too low 3.1 Downstream power levels & errors, but also note the 3.0 Downstream power levels have and unusually large spread across the channels.

Getting absolutely nowhere with telephone support. "Factory resetting your superhub will fix it." It's good to know that in the time I've been away, the call centre hasn't changed.

Hi @fatedsnowfox thanks for your post although we're sorry to hear of your concerns raised.
We can see there's some issues with the power levels so we'll need to look at sending an engineer out to resolving this but please let me send you a PM so we can look into this further.
Kindly expect the PM from me to arrive shortly and respond directly when you can!
Many thanks
Tom_W
