@Wheelsinmotion Sky do not provide wifi boosters free of charge. The main way you can get an extender is to buy Sky's WiFi Max bundle which can provide up to 3 extenders.The extenders each have 2 ethernet ports.
However there are probably better ways of sorting slow connection to your PC. Assuming running an ethernet cable from the hub to the PC isnt practical you may consider buying a Powerline Networking kit that uses your home's mains wiring to carry the date. You need a kit with 2 adapters one plugs intoa wall socket near the hub and linked by an included ethernet cable. The second adapter plugs into a wall socket near the PC and is similarly connected. To just network that device you do not need to pay for adapters with built-in wifi accecss points.
