Openreach ONT has a red PON light
My Openreach ONT has a red PON light. Power and LAN are green and Alarm is off. I’ve restarted the ONT, but PON is still red and I have no internet.

Re: Openreach ONT has a red PON light
Try running this line test to see if it finds any faults:
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

Re: Openreach ONT has a red PON light
Thanks for your reply. I tried to restart the ONT several times, but PON is still red and I have no internet. Therefore, I have requested for an engineer visit.
