Check the lights on the ONT unit as they will show if there is an issue wuth the connection. The one lzbelled PON should always have a steady green light and one labelled LOS should noot be lit. When calling Sky explain the history.</P> Fri, 23 Jan 2026 09:35:36 GMT https://helpforum.sky.com/t5/Broadband/New-fibre-broadband-intermittent/m-p/5196519#M548177 Chrisee 2026-01-23T09:35:36Z
