How come when I turn on my Olympus OMD EM-5, I can't see the Wi-Fi signal from my Wi-Fi SD card? Category : Network Connection / Data Transmission The power-on voltage of the Olympus OMD EM-5 sometimes rises too slowly, which can prevent the Wi-Fi signal from appearing. We suggest that you turn the camera on first and then insert your Wi-Fi SD card. Is the answer helpful? Related Why would the downloaded data be incomplete when using the automatic download function on the Android WiFi SD App? My Laptop asks me to install the diver after I insert the SD/SDHC card into the internal card reader. Please provide me the driver. Why can't my mobile phone and tablet search any Wi-Fi signal after the Wi-Fi SD card is inserted into Nikon DSLR?
