WiFi drops out

[Gemino]

WiFi connection on alll devices is intermittent. All 3 lights on the broadband router are green.
It has been working for years without issue.
I have alted the wireless channel from auto to 6.
I have re-sited nearby electrical equipment.

Still the issue persists.

Any ideas what I should try? I tried calling but they said report it online. I submitted a complaint but they just sent me on the same circle that has no end nore resolution.

My Internet has stopped working about 30minutes ago. When I've done a broadband and WiFi check it's says everything is good but it's not because nothing is working in my house that requires Internet. I've unplugged the router and back in again but it's still not working. Hope the issue is resolved soon.
