Persistent disconnections - Solihull B90

Connection was fine until 2nd July, over the past week things haven't been great - but it was tolerable, however the the past 24 hours the connection quality is absolutely miserable.

Hopefully there's enough detail further below for someone to have a look.

BQMs:

A lot of 'Post RS Errors', which would need to be investigated further by VM/Engineer visit.

Re: Persistent disconnections - Solihull B90

The BQM and Network log confirm that your connection is a disaster with persistent packet loss, poor latency, disconnections and critical errors.  I can flag this for the forum staff, but before I do that can I ask that you try a pinhole reset of the hub - or confirm you've already done that?  It might work if the hub's firmware has become corrupted (a low probability, but it does happen), and VM will need you to have tried that to ensure that all avenues have been explored before getting a technician out.

Re: Persistent disconnections - Solihull B90

Was ready to contact support to get an engineer to look at it, however shortly before I got around to that - a local 4 hour outage occurred:

Which seems to have fixed the issue.

A much more stable connection!
