Turn off onboard pi3 wifi

[fzinken]

Well the answer is a bit hidden in the Pi3 Wifi Mega Thread but still could have been found

Raspberry Pi 3 - ***Wifi Mega Thread***

Hi Using latest OSMC on rpi3. But dont see onboard wifi in osmc settings. Heres debug log Heres dmesg log I transferred updated sdcard from pi2 to pi3. Thanks for any info Edit Solved: by removing the line dtoverlay=sdhost from config.txt. Seems sdhost is already enabled.

Just add dtoverlay=sdhost to config.txt will disable the onboard wifi
