How to turn off Raspi Zero’s internal wifi

This is the right answer.

Rewrite blacklist in mod probe.d

Then, as the link below says, if you plug in the USB cable, you can access it with raspberrypi.local

The above could not be done, either,

I was wondering!

I converted it from LAN port to micro USB and connected it!

However, it is very slow,

Not for development use.
