I have unplugged it several times and reset at the hub and all connected devices 

we cannot establish why we cannot get the internet on cable or WiFi.

@AustinBr use this trouble shooter https://www.sky.com/help/articles/hub-lights-explained-start

If as sounds likely and you have a fault on the line connecting your hub to the exchange if the service checker does not show that Sky are aware of a fault affecting your line then call them to report it.
