No WLAN0 Interface on 8GB Raspberry Pi 4b with Manjaro Minimal?

I saw this thread with a similar problem, but on a Raspberry Pi 3b. I’m not experienced enough to know if the same solution will work on a 4b. :frowning: Wlan0 interface is not seen when running RPI4 minimal 20.12.1 image on RPI 3b+ - #2 by Darksky

iwd is enabled and active, but can’t find any interfaces. The wifi interface is not showing up when looking at inxi -Fazy, either.

uname -a:

Linux Nicole 5.10.76-2-MANJARO-ARM #1 SMP PREEMPT Thu Nov 4 10:38:27 CDT 2021 aarch64 GNU/Linux

You are not really giving any info on what you have installed there. WIFI
should work out of the box if you installed an image with a DE.

Sometimes people have to install crda and set their country code. Sometimes people have to change the WIFI channel in their router.

If you installed a minimal image then I am not sure what all needs done as I never use a minimal image. It may need some manual configs to get wifi going.

Sorry; I was in a hurry and ended up being more vague than I realized.

I am running Manjaro Minimal, so no DE is present.

This problem fixed itself when I did a clean install of the latest Minimal image from the website. I have no idea what was going on with it before.

Could it be you messed with it. :sob:

Almost certainly. :wink:

I just can’t remember what I did. I didn’t mess with the wifi at any point before that, and didn’t try plugging in any USB network adapters before that, either.

Best guess: when I disabled bluetooth I took the wifi interface out with it without realizing it. I haven’t disabled bluetooth on this reinstall, yet.

So, um. Don’t do that thing I did that I don’t know what I did. :stuck_out_tongue:

sudo systemctl disable attach-bluetooth
sudo systemctl disable bluetooth
sudo pacman -Rdd blueman

Thanks!

I was doing things in config.txt to turn off bluetooth. Pretty sure I killed the Wi-Fi in there. :stuck_out_tongue:

I do not mess with it in config.txt. If the attach-bluetooth is not disabled it can causes network issues and cpu usage trying to connect. I basically cut the head off the snake.

I assume removing blueman is to deal with that bug where it completely pegs at least one CPU core when the service is disabled?

Thanks.

Not really sure blueman gets installed on a minimal image. It may not have a TUI.
