@1997Shannon a new Sky hub will not have improved the speed your line delivers so first thing to check is the speed to the hub which is best done by using the service checker in the My Sky app which will tell you the current connection speed if you click on thst it will show the history fir the past couple of weeks and ghe guaranteed speed for your line. If the line us running slowly the app should offer further help.
If that is not the issue then try testing speeds close to the hub to see if they are close to the speed the hub is getting the issue is simply the signal is not strong enough where you were testing before. However multiple devices using the connection have to share the bandwidth of the connection so for exampke somebody streaming video on a slow line can stop other people using the connection.
