Thanks for taking the time to post on the community.
Sorry to read you are experiencing intermittent broadband connection.
Looking at your connection, the line and hub have come back as fine.
Does this happen on both wired and wireless devices?
Do you notice any lights change on the router at all?
If you can post your router information, that would be very helpful. To do this type in 192.168.0.1 in the address bar, no need to sign in, on the top right you will see router status. Within here you will have downstream, upstream and network log. You can copy and paste this information, that would be great.
