Hi Gerard-London,
Welcome to the community!
From reviewing the error code it would indicate that it is a V6 box.
The first step I'd advise is to reboot both the Hub and the TV box (not from the mains) and ensure both coax cables are securely fastened.
If that doesn't resolve your issue then, please reconnect the TV box to the router via these steps;
Navigate to Home>Help & Settings>Settings>Network>Change Network Settings
Once done, select the option Connect to WiFi
Let us know how you get on!
