Nope! My advice is give up on the hub and use it only as a modem. I bought a mesh WiFi system and since day one of turning that on and having the Virgin hub be only a modem I haven't had a single issue.
The Virgin hub is not fit for purpose when trying to be a modem and WiFi router and massively under spec'd. It works fine as a modem only.
I've had a relatively stable performance for a couple of months since getting VM, and was hoping to avoid forking out for my own router if I could help it, but since getting this issue recently I've been googling and seems you're not the only one to have the issue without resolution. Shambles from VM.
Don't suppose you managed to negotiate a discount for having to pay for your own device just to receive a stable service?? 🤔
Sadly that won't wash. I had the same argument but the first stage in their troubleshooting is a reboot which always fixes the issue. Nothing shows in the logs and they cannot seem to do any level of debug. I was annoyed I would have to buy my own gear but as a techie I soon realised just how bad the hub was and how much better my network can be with kit actually designed to run properly.
I've had 3 outages in the past week-10 days. Each time the following appears to be the case:
All Wifi connectivity goes down
The hub is inaccessible (i.e. I can't ping it, or browse to the http interface)
My device loses its IP and gets an APIPA address (169.254.x.x IP that a PC gives itself if the DHCP server isn't issuing an address)
My thinkbroadband monitor doesn't show the internet connection is down
So the long and short is that I don't think the internet connection has gone down, it seems to be the Hub 3.0 freezing and locking up.
To fix it, I've just had to power cycle the hub and everything comes back after a few minutes. When I check the logs, there's nothing to indicate that anything happened around the time of the outage, again suggesting the hub is just hanging and it's not caused by any upstream issues that are getting logged before the outage occurs. Obviously this is my assumption and I can't say this for definite.
I have 2 other APs of my own and I can't connect to them either as the hub is the DHCP server so devices just can't get an IP. I have a few devices wired in, but I haven't specifically tested to confirm that they're working when this occurs, but I'm 99% sure they're not. If it happens again I'll test this immediately before rebooting the hub.
In answer to your specific questions:
1. No my speed isn't 0. It was a facetious comment to state that when things go down my connection is 0. The speeds are OK when the outage isn't happening.
2. Yes, I have checked the service status page and there's no known issues. As you can see from the above, it doesn't seem likely this is the cause anyway.
