3 green lights - no internet

[Sam2023]

3 green lights - power, WiFi and internet. 

no light on voice - not connected to a phone! 

No internet at all, on any device. Tried other wires, tried resetting on the router. Nothing is changing - turned off for 30 mins. 

All this has happen since turning the sockets off to the house this afternoon for 10 mins. 
Tried everything the internet has suggested

@Sam2023 With Sky's network you have to leave the hub off for at least 60 minutes for the connection to fully refresh so if your hub is still down this morning try thst if still stuck call Sky.
