@martinnaughton Welcome to the forums. How long have you had the hub? Have you tried it in another socket? Have you had any power cuts/surges? What, if anything, did you observe before the failure?
Thanks for your post @martinnaughton and welcome to our Community Forums.
I'm sorry to see your router won't power on. From what I can see, it looks like you've got this sorted as you've had a connection again from 23:35 20/Jul/2021 last night, about the same time you posted here actually.
Let us know if there are further issues though or anything else you'd need help with.
