@Niccase an Orange internet light indicates a loss of connection to the exchange. If it has been down for more than an hour the Service Checker in the My Sky app run over a mobile connection should offer to book an engineer to check your line if you run through the tests. If there is an area fault affecting your line thecapp should show that as well.
It is unlikely you caused this loss yourself unless you disturbed the cables. If however you do lock a hub up it is simple to reset back to the defaults by pressing in the reset pin using a paperclip or similar for 20 seconds until the power led blinks and then releasing.. These instructions explain how to split the WiFi bands on a black hub Split Sky WiFi bands
