Router - LOS red, no Internet

[Jess8888]

My ONT is not working. The LOS light on the ONT is red - even after rebooting several times. How can this be fixed?

The LOS light is a physical problem such as a cable break between you and the headend.  It’s not something you can fix.  You’ll need to phone it in to Sky and they will arrange for Openreach to investigate.
