[question] Setting up wifi on existing rpi with HA


I want to setup wifi on my RPi 3b+ with home assistant on it. I followed the installation instructions here, but these are instructions for booting the first time, and my home assistant is already live for some time (still DHPC and wired).

So I have setup a 2GB usbdrive, formatted to FAT32. Made a folder " network" and placed a file without extension in it with the name “my-network”. Used the template from the documentation from HASS.

Tried to reboot > nothing

Tried the button “import from USB” > nothing.

There are no updates to install (it said that it would import during an update), so I can’t do that.

Why does it not work? What can I do to set a static IP + wifi?

(the USB has the name “CONFIG”)
