Hi hammerandtongs
Have you used the /check-services/i function? You can also a run a test on your equipment from there.
If nothing is showing you could also try the automated Service Status number 0800 561 0061. This often gives details of more local issues down to postcode level.
Have you tried factory resetting the hub?
You will need to log in again with the passwords from the bottom of the hub so make sure they are legible.
Also make sure that you use the admin password and not the wifi password to log into the hub settings.
Please try the following exactly as typed.
Disconnect all ethernet cables from the Hub.
With the Hub powered on use a paperclip, or a mobile sim slot tool and perform a pinhole reset by keeping it pressed in for a timed 60 seconds
DO NOT reboot the hub but allow it 8 to 10 minutes to boot up and settle down.
