Router3 showing red light. I’ve reset, unplugged and plugged back in and the red light is still showing.

Hi Lyndabrooker,

Thanks for posting and welcome to our community  😊

Sorry to hear you're having some issues with the hub, so I can help I've popped you over a private message to get a few more details from you.
