Indoor Cam not Working or entering setup.

I have two Indoor Cams and for some reason both have stopped working. In the App it says neither are connected to Wifi, however when I go into my WiFi FRouter settings it says they are both connected. I have even taken them into my lounge and put them about 30cm away from the router, still not response.So I have tried to set them up again, deleting them from the App and then trying to get them into setup mode. I even tried a hard reset (30 seconds on the button) and this also does not work, they both will not go into setup mode.
