@Dominohoohoo are you referring to fixed line broadband wifi in your home or mobile signal strength?.
The wifi signal strength from a Sky hub will vary with distance and what solid objects the signal has to pass through between the hub and where the device is. It has nothing to do with the speed of the service to the hub. Given each home is different it is difficult to know what is going on with your set up. You can have a strong wifi signal and have slow speeds where the speed tomtge hub is the issue and equally a weak wifi signal with reasonable speeds.
