Hi,
Hope someone can take a look or help, having issues with with my my Hub 3.0 possibly. It started randomly rebooting for last two days. Network log hasn't actually recorded any issues at all or anything actually for past 2 days. Apart from LAN login success and a normal DHCP renew on the 14th. No T1-T4 timeouts on upstream and Downstream looks fine as well, Power (dBmV) between 1.7 - 5.8, 24 channels, no Pre RS or Post RS errors. SNR (dB) is the same as it has been for the entire year, 36-37
Even just as a test, swapped out the cable with a spare rg6 coaxial cable I kept from a sky box. Still Reboots...even without any devices connected at all to the network (yes, terms and contract I put the old cable back)
Any help would be appreciated

Hi. Had the same problem. First engineer to call played around with cables without sucess. Second engineer replaced my Hub 3 with new Hub 4 and not had an issue since. Based on my experience and other comments on this subject in this forum I definately believe its a Hub 3 issue. Try and insist you get your hub 3 replaced with hub 4.

I would be worried if both a sky coax cable and one from my workplace would be of lower quality, especially one from work. For testing purposes as long as the original is put back in place it rules out cable issues, so had to be done to rule it out. With covid and various people still getting it I would rather break the T&C slightly to test than catch anything as have a vulnerable partner.
Noticed Downdetector has virgin media users flagging up reboots and connection issues past few days...they seem to have posted this morning around 9 the same time they started happening again...https://downdetector.co.uk/status/virgin-media/ wouldn't surprise me anymore if it's just VM

Is there a way to book an engineer or get something raised without having to phone...cannot get through at all
End up getting the message, which is useless...
Thanks for doing your in-home checks. Please pop back 24 hours after you've done these checks and if you're still experiencing intermittent blips on your service you'll be able to book an engineer appointment online.

This morning internet has gone off again a couple of moments ago, Line stats from this morning, differ from yesterday and noticed before every reboot, while nothing is captured in network log I get
Internet(Access denied) under the Hub 3.0 Status, believe this can be caused by dodgy cabling/the cabinet looking at other post, and with the error message from the test seems to point to the same.

May as well use this as a log as currently still happening, white light flashing on HUB 3.0, multiple red lights, it reboots then reconnects. Still nothing in logs and stats have changed, see below. Happened a few seconds ago
Acquired Downstream actually went as low as 306xxxxxxx earlier on?

I can set it up to keep virgin media happy...but not sure how I need to justify a very basic issue of the actual HUB 3.0 restarting compared to wifi dropouts, when I have tested directly via ethernet and Wi-Fi from the HUB itself and through another router setup in DMZ to forward all traffic which I had to install, running the wifi/ethernet through it as well as I already had issues with the known HUB 3 problems with the puma chipset being crap and UDP traffic crawling to 0 when in modem mode.....to stop any network drops with large UDP traffic, I am literally sat in front of the HUB which is across the room and can see it when it reboots and reconnects on the status page to the internet, which it wouldn't do from a simple wifi/lan dropout....disconnected every device, both wifi and lan and still having full on network dropouts/hub rebooting by itself should be investigated regardless of BQM or me having to prove that the quality is crap with a free checker...any previous ISP if there was connection issues and Dynamic Line Management kicking in on VDSL, would send out an engineer pretty quickly without any issues especially when the SNR margin was too high or it was set to interleave and showing pretty high, without any quality checker and would make sure the basic checks have been done and that's about it. I just don't appreciate how you have said "true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts" - if it was a simple wifi/local network issue I wouldn't be posting here....trust me, rest of the network has been including tcpdump and capturing of packets from 3rd party router and has been fully tested including latency etc. it's either down to VM's equipment/network and which they should provide support.
Will post BQM, may as well post anyway to move process along will do it from VM HUB rather then 3rd party router with ICMP echo requests allowed. Just as troubleshooting has been carried out...it's kind of narrowed it down already, live BQM below
