Wifi connected but hub lights arent on

[Kiya]

Hi

When checking my WiFi connection it's saying it's good and there's no issues. But my hub has amber lights on internet. This happens most evenings. 

I'm beginning to wonder if there is an issue with my hub?

@Kiya the WiFi connection of a device to your hub is separate from the broadband connection of the hub to the internet. The amber internet light indicates the hub has lost connection to the exchange. At 1.30am it is quite likely that loss of connection is due to essential network maintenance by Openreach or Sky. The service checker will not pick that up until the hub fails to respond to a signal. 

If your service is back this morning then maintenance work is the most likely explanation this work can take several nights.
