Red LOS light on ONT

I have no internet and red LOS light on ONT. Tried multiple restarts. Service checker says no issues and no way to report to sky? Any ideas?

@09lriches First thing to check is this link to see if there are any outages in your area:

https://www.sky.com/servicechecker

If there isn't try running the line test here:

https://www.sky.com/help/articles/broadband-diagnostic-start

You can also run the test via the MySky app on a mobile data connection.

After this has finished and if it reports back all is good click on broadband to run an updated test. If you get amber or red please follow the on screen instructions.

Please be aware that outages after midnight are usually down to maintenance, please see this pinned post https://helpforum.sky.com/t5/Broadband/Important-Notice-Scheduled-Broadband-Maintenance/td-p/5151847#

If your ONT shows a Red Light please see this guide https://helpforum.sky.com/t5/Broadband-Talk/Can-t-connect-to-broadband-and-have-a-red-light-on-your-ONT/ba-p/5151861#
