Red light on front of Hub 3

Hello all,

Recently noticed that our old Hub 3 router now has a red light on the front instead of the usual white one. This alarmed me somewhat as red is rarely a good sigh in IT, motherboard/CPU/GPU fault, bad sectors, etc, etc.

So I did a bit if digging and found several topics on the issue, many of which seem to have popped up pretty recently (firmware update?)

The router is in a well ventilated spot and I have tried the re-boot, stick a paper click in the hole to reset to default, ran the network diagnostics and it`s still showing the red light!

Any other things I could try or is the router possibly on the way out?

Many thanks,

Mattchu
