Red LOS light no PON light
Come 8Pm tonight my whole internet stopped working, checked the app it says everything is running fine and my devices are connected. Come to check my router a few minutes later I've got a Red LOS light and no PON light, I've tried restarting everything but two hours later nothing.

Re: Red LOS light no PON light
If your ONT shows a red light then have a read of this:
https://helpforum.sky.com/t5/Broadband-Talk/Can-t-connect-to-broadband-and-have-a-red-light-on-your-...
If nothing there helps then the first thing to check is this link to see if there are any outages in your area, it can be a bit slow at picking up issues so if nothing shows perhaps try it again later:
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 someone has helped you then please click on the LIKES button in their post.
If you need help please provide as much information as you can
