Your Downstream power is too low, should be above -6 and too many PostRS errors which is indicative of “noise” on the line.
A VM Mod should pick this up in a couple of days and discuss with you.
Following my earlier post on Tuesday the problems continue and have been particularly frequent over the last two evenings .
The following BQM outputs show the situation yesterday and today before and following a router restart
Attached are Router stas after restart

Addix previousy identified issues with low downstream power levels which now seem to be even lower on more channels he also identified high upstream power levels.
Can VM please look at the data and advise what the issue is and how it can be resolved.
Yup upstream power levels look high to me and downstream are also a bit low. Check for local faults on 0800 561 0061 otherwise call it in as a fault on 0345 454 1111 / 150.
The BQM indicates there was a total loss of service from 1am to 9am the following day.
Yet there is not a single word about this in the original post.
What is the BQM pointing to ? A generic VPN exit point perhaps ?
Sorry I did mention in second post that despite BQM showing 100% packet loss internet was working fine but post exceeded word count and this was lost. BQM points to IP address shown by BQM What is my ip address tool.
… Or the public IP address has changed and the BQM is thus no longer in contact with the hub.
Is there an attenuator on the back of your hub? If so, please remove it and keep us informed. Of course, the coax cable need to be tightly screwed inn at both ends.
there is what I believe to be an attenuator on the phone line connected to the hub but no other that I am aware of.
Check the BQM IP it does not appear to be a VM Hub.
For our Hub the Admin >> Info section of the Hub's menu shows the IPv4 address use this IP in BQM.
What is my ip address tool will return the wrong answer if performed over a VPN or via Apple Relay etc.
IP address on Broadband matches that in Hub Admin Info
