By default, the Wi-Fi SD card will automatically broadcast wireless network signal once the camera is powered on. You could find the SSID (WIFISD) shown on your mobile device (this is an instant sharing mode).
To avoid Wi-Fi disconnection when cameras go into power saving mode, please check if the camera is supplied with sufficient power. We suggest you turn on the Live View function, and adjust/turn off power saving mode.
If you do not have or don't want to turn on the “Live View” function, you may adjust the time of Auto meter-off delay or Standby Timer in the C2 settings to 5 mins or longer.
