If you’ve experienced a problem connecting the WiFi on your Nikon D750 to your tablet, I’d like to show you what I did and it may solve your trouble. I’ve already downloaded the Nikon Wireless Mobile Utility (WMU) to my Apple iPad IOS 14.4.1 so watch this video as the Nikon Camera Cowboy navigates and encounters obstacles - but not to worry! The connection is made and photos available for use on the iPad. Let me know if this helps you.
