@Lesleypatricia You never want to have an Amber light on the sky Hub, all Green on some is great, white on others so depends on which one you have, linked below if you need to check!
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!
