However in this condition normally the red LOS light on Openreach ONTs is on (Loss of Signal). </P> <P>&nbsp;</P> <P>Can you post a picture of the ONT? It is possible it msy not be the correct unit if you have moved into a property where the previous occupiercwas using a different network like Virgin their engineers helpfully remove the Openreach unit and fit their's instead. Openreach ONTs are branded with their name.</P> Tue, 01 Sep 2026 13:57:56 GMT https://helpforum.sky.com/t5/Broadband/PON-light-not-on/m-p/5360395#M590457 Chrisee 2026-09-01T13:57:56Z
