hello, i have a usb wifi card which works fine. problem is when i disable my built in wifi in
/boot/userconfig.txt with dtoverlay=disable-wifi volumio os interface sees wifi as disabled, you have to put in cable and enable it, then usb wifi works until next reboot.

This is reproduceable.

on the Raspberry Pi 5, the string to add to userconfig.txt for disabling the onboard WiFi module is the following one:

dtoverlay=disable-wifi-pi5

Introduction
============

This directory contains Device Tree overlays. Device Tree makes it possible
to support many hardware configurations with a single kernel and without the
need to explicitly load or blacklist kernel modules. Note that this isn't a
"pure" Device Tree configuration (c.f. MACH_BCM2835) - some on-board devices
are still configured by the board support code, but the intention is to
eventually reach that goal.

On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By
default, the Raspberry Pi kernel boots with device tree enabled. You can
completely disable DT usage (for now) by adding:

    device_tree=

to your config.txt, which should cause your Pi to revert to the old way of
doing things after a reboot.

In /boot you will find a .dtb for each base platform. This describes the

that will indeed disable rpi5 wifi, but after reboot there will no wifi at all until you actively enable wifi again like on @SimonE screenshot, THUS you cant disable built in wifi if you use volumio headless and want to reboot from time to time… this is a bug.
What I want is my usb wifi to be the only active wifi.

keep WiFi active on the network settings page
add the string on userconfig.txt, to disable onboard WiFi
connect your usb dongle
reboot

thanks for replying but that wont work. the wifi will automaticly disable If I disable built in wifi on userconfig.

If I plug in a cable and enable WIFI in the settings page, it will work until next reboot.
