I have connected my Pi3 with an ethernet cable.
Looking for a way to turn off the on-board WiFI, I found the instruction to add to the config.txt:
“dtoverlay=sdhost”
Looks like indeed the wlan0 is turned off and I am using the Ethernet.
But… is that correct? What was that command supposed to do?
On a piaware sdcard image you can do piaware-config rfkill yes to turn off the wifi radio
On vanilla Raspbian you can run something like rfkill block wifi (not sure if that is persistent)
Thanks.
The command that I have quoted weirdly turned off the WiFi, but it’s proper usage would be something like this - overclocking the SD card port from the default 50 to 100MHz (needs a fast card):
"dtoverlay=sdhost,overclock_50=100\n"
A clean and persistent solution is simply to uncomment (or add) the following line to /boot/config.txt and then reboot:
dtoverlay=pi3-disable-wifi
Best regards,

That worked! Thanks!
