Re: Sky fibre ethernet problem
If you have Sky Fibre and 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

Re: Sky fibre ethernet problem
Thanks for the reply,
I have tried all the steps as shown on city fibre site and also on my sky app
When you switch off ont,wait a couple of minutes, then switch it back on it all works for about 20 mins or so , then ethernet light on the ont goes off and sky max hub red light comes on and all broadband is lost
Im going to get a new cable to try that, but dont know if thats a waste of time?

Re: Sky fibre ethernet problem
@bigmurs it is worth trying swapping the cable but In suspect either the ONT is bad or there is an issue with the hub both of which will require Sky's assistance.
