Thanks for your post on our Community Forums @Clairb37, and a very warm welcome to you!
Sorry to hear of the issues with the broadband connection.
Are you able to advise me if you experience an intermittent connection on any devices that are connected via an Ethernet cable, or if this is restricted to Wi-Fi?
Do you experience Wi-Fi issues in the same room as the hub?
Are there any devices close to the hub that would be connected via an Ethernet connection?
Kindest regards,
