Simplisafe camera

If your Simplisafe camera not connecting to Wi-Fi, first ensure your router is set to the 2.4 GHz bandwidth, as Simplisafe cameras are not compatible with 5 GHz. You should also check that the camera and base station are within the router's range. If the issue persists, try rebooting the camera and base station or performing a factory reset as a last resort.
