@Kieron27 you cannot use a Sky hub to extend the network you require a booster or extender matched to the Sky hub you are using to conect to the broadband. Normally WiFi will go beyond a single room but if you live in a housecwith solid internal walls you can have issues even one room away. Sky will sell you an add-on called WiFi Max as explained here https://www.sky.com/help/articles/sky-wifi-max which can include extender pods iif required or you can buy your own wifi kit and use that.
