Thanks for your post on our Community Forums @BM3, and a very warm welcome to you!
Sorry to hear of the red light currently showing on the router. This is usually a sign of the hub overheating.
Can you please confirm if the hub is hot to touch?
Please try switching the router off on the back of the hub and then unplugging it at the mains and allowing it to cool down for 30 minutes.
Do then please reboot and see if the red light re-appears. Once completed, please report back to us with the outcome.
Kindest regards,
