Router keeps restarting

[BillyA98]

On Monday I upgraded my internet package to gigafast fibre. 
Starting yesterday, the router randomly fully restarts. 
It happens when I start a download of something originally, but today its now just loading pages and the router completely restarts. 
Also the voice light is orange and has been since the upgrade. 
It's dropped 5 times today when I've been awake and doesn't help for someone who works from home

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 this is of no help give Sky a call to report it to them.
