@DSSingh in many homes a single Sky hub wont give usable WiFi in every room. Eaxh home presents different problems as WiFi signal strength is affected by the layout, type of construction and level of interference.
If you buy one of Sky's add-on package like WiFi Max or Broadband boost they will supply an extender or booster otherwise you can buy your own third party kit.
However before spending money check tge hub is in the best position which is out in the open on a surface above obstructions like radiators.
