G'morning Jenny........I wouldn't regard your present speed as good, although your test has reported so.
Hopefully the Hub will settle down and speeds will improve, but it could take a few days to do so.
Don't expect to get high speeds like Baldrick has because he is not on standard broadband. I feel certain he has something like BT Infinity, which is more expensive.
Keep an eye on speeds and keep us updated. For an easy to use and accurate tester I suggest you try the following :-
