No broadband. Router not letting anything connect.

My internet won't let any of my devices connect to it. 
I have had zero connection since yesterday. 
Done the test my broadband again on the app and it's coming back saying there's an issue with my broadband. 
There's normally 3 lights on the front of the router lit up green. I have 1 green for power. Internet flashing orange then WiFi green. 
I've switched off at the wall and left for 2 mins then switched back on numerous times & still not working.

Have you run the broadband test from the app (the image you posted show an issue) so you need to select that.
