As far as I remember  the l o s light being on means there is a problem  with  the fibre  optic cable  as that light  mean loss of signal , you will  need to ring  sky  and get them  to arrange  an  engineer  visit by the sounds of it.  I have  fftp  with them and if everything  is working  OK you  should  have 2 solid  lights and 1 flashing  all should  be a yellow  colour which is what I have on my o n t box, hope this helps you

@Freakz  Is this still the case this morning that you have the red LOS light on the ONT, can you follow the directions below.

Can you please run the service checker, this can be done either via the Sky app on mobile data or use the link below.

If it finds an external fault it should enable you to book an engineer.


After the service checker completes and if it comes back green all good can you click on broadband to run an updated test please. If you get amber or red please follow the on screen instructions.
