I have non internet and the red LOS light is on the ONT. I have unplugged and reset, the red light came back. I cannot connect to the internet.

Re: Red LOS light on ONT
@Roxanne17 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.
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-...
