I've had a Hub 3 working virtually flawlessly for a number of years but in the past couple of weeks it has become increasingly unstable and it is now frequently dropping connection and becoming unresponsive on 192.168.100.1 (it is running in modem mode for my Orbi router). A power cycle will usually resolve the issue for a while, but the connection will drop again sometime later.
The network log shows a whole load of errors so I am guessing it is an issue with the connection rather than the hub itself, but the virgin media status page claims normal service in the area.
The logs confirm that your hub is dropping the cable connection (that's "RCS partial service"). Upstream stats look OK. Downstream looks as though you've restarted the hub and thus cleared the error logs, so I can't comment on those. SNR and power levels are nominally within spec, except that the range of power levels looks likely to be outside the (probable) spec for the Hub 3. VM have never released the specs, but data for a similar device from the OEM who make the Hub 3 states that power levels should as close as possible, but must not vary by more than 3 dBmV, so that seems a likely value for the VM hub. Yours is showing a range from +2 to +6.6, so I'm suspecting that the range of your power levels may be associated with the problem you're experiencing.
Wait for the forum staff to pick this up, it'll probably need a technician to visit and fix it.

Thanks both - looks like it was a network issue after all as although I initially had an engineer visit booked in, a short while later I got a notification that there was a fault in the area being investigated and it seems to be resolved now.
I'm having exactly the same problem as described in this post.
It was happening with my Hub 2 every day at least once for the last few weeks - I managed to replicate it when I did a significant upload. I changed package (upped the internet bandwidth) and received a Hub 3 (previously used, from the logs) 2 days ago. This would not work at all until a software update was applied by the fault team, after 90 minutes on the phone.
The Hub 3 is in modem mode, and every few hours the internet is lost and the hub does not respond on 192.168.100.1. Poweroff/on solves the problem for a couple of hours. Overnight is when my NAS backs up to the cloud (not huge amounts of data) and the connection went down 3 times during the first night, with nobody doing downloads. We have 2 adults working from home and our 2 university age kids hitting the internet all day so the service is effectively unusable. Config reports below. Do I need an engineer?
