Frequently throughout the day the wired PC's and devices linked by WIFI show no connection, this begun Thursday morning.
Using the "Virgin Media What do you lights mean" would suggest everything is fine.
When this just happened I tried to login to the SH2 to get the network logs but was unable to on a wired device! It was only after restarting the SH2 and all connectivity had resumed that I was able to login and get the details.
(I will create a BQM monitor today to track going forward)

All stats look OK except Upstream qams are all at 16 that may be the issue - network logs tell another story. See link below for pointers to what they mean (should be same on your older Hub)
The BQM will be useful data to see - post the link to "share live graph" as soon as

Also same thing just happened, this time I went to the 2 wired PC's and the WiFi PC and could not access the SH2 on any, yet the lights were blue from bottom to top.

Hi s71rl2, thanks for getting in touch.
Sorry to hear about the connection issues you've had. Thanks for flagging @jbrennand.
I've taken a look from here and it's a strange one, everything appears to be fine but I appreciate the hub logs tell a different story.
I'd like to double check a couple more details via PM but in all likelihood we'll need to arrange a visit from an engineer to check things over. Please look out for the purple envelope icon and we'll take it from there.

Thank Tom, it's actually driving me mad because everything is perfect, everyone is enjoying fast speeds, even on Wifi, multiple people gaming watching Netflix etc all at the same time, and then out the blue everyone slowly congregates downstairs around the SH2 as their kicked from games and TV shows stop.
After the reboot its back to a very good service for a few more hours.
on 26-09-2021 15:29
Thanks for getting back to me @s71rl2. I still can't see what might be causing this so I've booked a visit for the day requested - you'll find confirmation of the appointment via your online account (virg.in/myVM) and can reschedule from there if needed. Please keep us updated with how you get on.

Thanks again .@jbrennand
Prior to issues beginning I was in modem mode using an Asus Rt-AC88U with a Home Mesh extender on the second floor - also because of work I also have an unmanaged Netgear GS305Pv2 with PoE for my VOIP phone and also the additional ports for the random other devices I need to plug in (payment terminals)
This had been my set up (albeit with an older switch till last 6-9 months) for maybe 4 or 5 years.
When it all started going wrong the first thing I did was remove all of this and just go back to the SH2 in "normal" mode and this hasn't made a difference.
