WiFi not working despite all the lights being on

WiFi won't connect to any devices in my home, it'll come up as being there but won't let you connect. Sky saying nothing is wrong but there is

What happens if you reboot the broadband hub at the mains, give it 5 minutes or so after powering it back up to see if your devices are now working.

No it still doesn't work, I have done all of this. Yet it still won't connect to any device in the house, no matter what I do. It was working one minute and the next absolutely nothing.

I have the same problem, I have restarted everything twice. Called sky and they say there's a problem with the wifi in the home and sent me a link to go online for more 'easy fixes'! The service checkers indicate everything is working and the lights are all on on the router (including the wifi light), so it's not clear how this should be resolved. Internet connection in the house is very poor so trying to use Internet without wifi is a nightmare (I already have a booster).

I phoned and they have sent me out a new router! But I'm without wifi for the next couple of days! It was working one minute and the next it's not, it's been off since about 3pm

@LisaD1 What do you see with the hub light or lights. And which hub do you also have from the link!
