Only 3 lights on router

[Thomasjam]

Hi,

I have been a sky customer for 5 years and on Friday I had fibre fitted everything was fine till I got a text saying that my activation had gone through now I have no internet. The voice light on my route is blank. I feel like I have a wire missing which is preventing it from working

@Thomasjam Can you please run the broadband test, 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.
