Issue with Wifi- two green dots two yellow dots

[Jane1999]

The wifi in my house has completely cut off since Friday, and we've had Sky wifi for two years now with no issues. The dots for power and wifi are green but the internet and voice buttons are yellow. We've tested the broadband and reset it over and over with no change. Any ideas would be so appreciated. Thank you!

I'd like to add that I ran all of the service checks and tests, and it said there was nothing wrong with my area or my wifi.
