Hello,
I’m having an issue with my Canon 5D Mark IV. After connecting the camera to my computer via USB to copy photos and then unplugging it, I try to enable Wi-Fi (Menu → Setup → Built-in wireless settings → Wi-Fi/NFC → Enable). The option lets me select “Enable,” but Wi-Fi never actually turns on, it remains off.
I have already tried:
- Clearing communication settings
- Clearing all camera settings
- Removing the battery for an hour
- Re-entering a new camera nickname
Has anyone experienced this before? Any advice would be greatly appreciated.

Greetings ,
On the 5D Mark IV, you cannot enable Wi-Fi if there is an active USB connection.
