Exactly that. Early hours yet, but initial view is a very poor broadband connection, which can usually be resolved when the probable cause has been identified. Getting that fixed will sort out most poor connection reliability issues, won't make a difference to wireless reach in the property, but worry about that in a bit.
As a next step, can you connect to the hub by clicking on this link http://192.168.0.1/ Or type that into a browser if the link into doesn't work. That should pull up the log in page for the hub. But don't log in, just click on the link "Check router status" That'll bring up a window with five tabs. Open the Downstream tab. Select all the text (Ctrl-A if using a keyboard), copy it (Ctrl-C), then paste it (Ctrl-V) into a reply here as TEXT not screenshots. Post that, do the same for the Upstream and Network log. You'll get an error message when you post the Network log, just click on "post" a second time.
Then we can check for any obvious problems with power, noise or error counts.
