Thanks for your post on our Community Forums and a very warm welcome to you!
Sorry this post hasn't been answered sooner, and that you've been having issues with your broadband service
Have you managed to get this resolved or is it still on going? If you're still struggling, have you attempted a pin hole reset on the Hub? This will return the Hub to it's factory settings but is known to solve some basic issues customers may experience.
Drop us a response and either I, or one of my colleagues will be happy to pick it up for you
