Hi @AdamT3 👋,
Thank you for your post and welcome to our forums 🎉
I have done some checks and cannot see any issues or outages that could be causing this. I can see there was some downtime on the 3rd and 12th of December. Can you please reboot and let us know? 
Thanks,
Zoie

[John0065]

I have a hub 4 and I need a hub 5 as have been told only the 5 has WiFi 6 E which my  devices need to make use of the technology 

[Molly_T]

Hi John0065 👋

You can compare hub specifications here 👉 Virgin Media Hub 3, Hub 4 & Hub 5 | Hub Swaps & Upgrades and find more information about the hub 5 here 👉 Virgin Media Hub 5 router - Virgin Media Community . 

Is there a specific device you are currently having issues with? We would usually provide a hub upgrade as part of a package change if this was needed to optimise your service! If this has not been the case, we would be able to arrange a replacement or a technicians appointment if needed to support with any fault you may be having. 

It does look as though you have also been in touch with us by phone since posting so please let us know if you are still requiring assistance and we will be happy to help. If you need support viewing or managing a technicians appointment you can also do this via 👉 virg.in/myVM 

Thanks for your patience whilst we get things sorted! 

Wishing you all the best. 🌞
