@Tex4x4 Have never known a sky Hub to stop transmitting the wifi signal or the ssid for connection, if that is happening to you then call sky 150 from your landline connection if that is still working! Link below if you are having Broadband Internet connection drops, the indication on the sky hub may help if showing to you!
This link below provides information about the coloured lights on the various hubs that can help to see what is going on! If the system is also Full Fibre then the lights on the OR/CF ONT also require to be looked at!
