Internet dropping out

[Michael1989]

Hi just wondering if you can help. Every evening over the past month my Internet continously keeps dropping out. Goes from 4 solid green lights to green orange green orange. I lose connection to my sky multi room each time also. Having to re sync over and over again. What is the cause for this please as its getting really frustrating now

@Michael1989 Can you please run the broadband test, this can be done either via the Sky app on mobile data or use the link below.

If it finds an external fault it should enable you to book an engineer.
