Hi, please can someone check my signal levels and error counts are ok?
Having frequent outages every other day. We work at home and it's affecting us a lot.
Background
I have Hub v3 and it's set up in Cable Modem mode with a separate Wifi router. I'm using cat cable and someone else is working on 5GHz wifi.
After complaining around 6 weeks back about outage frequency, around 4 weeks back, an engineer came out and put a 3db attenuator on our v3 Hub.
He said our downstream signal levels were too high because a combination of: 1) replacement of some faulty network infrastructure; and 2) our house being close to the street cabinet.

Thanks for the quick response! What are the expected power level ranges for upstream and downstream?

I guess something is going on...I hear this when calling 150: "Right now we are improving our network so we can give you the best service possible. This mean you'll be experiencing a loss of your broadband and TV services in the <postcode> area, everything should be back to normal by 3pm"
Well, I guess wait and see what happens.
Thanks again for your fast feedback.

Good point. Work appears to be complete - no message anymore on 150 for my area.
Rebooted around 4pm and 7h later, all upstream timeouts are all at zero.
Would you know of a tool that monitors the cable modem and checks the health status overtime? I'm sure VM have the tools in the back-end and I shouldn't have to do that as a consumer, though it's something that I'd be quite interested in monitoring.
Stability over past few months has been steadily deteriorating with regular outages. I'll keep an eye on these figures next week if there's another disruption. 👍

Hi, you can try https://www.thinkbroadband.com/

Thanks, I already have a ThinkBroadband monitor. I was wondering if there is a health check that monitors Cable Modem signal levels, ranges and errors.

Hello @CicadaEffect.
Welcome back to the community page, thank you for posting on here.
I can see you have been having errors with your cable modem signal is this correct? From what I can see on your last reply you have not been getting any more errors is that correct also?
Please let me know 🙂
