Manjaro-ARM-22.02 on Pi4B - no 5GHz WiFi

Hello everyone,

I am 100% new to Manjaro so please bear with me.
I downloaded Manjaro-ARM-kde-plasma-rpi4-22.02 and installed on Raspberry Pi4B.
I cannot see my 5GHz WiFi. Only the 2.4GHz.

How do I resolve this?


I am currently using Manjaro XFCE 22.02 on RPi4. My 5GHz WiFi shows up only occasionally as available. Other devices use 5GHz without a problem. Same problem for Manjaro Gnome test system. Not new to the 22.02 version. This has been around for at least a year.

I do not have 5G but the first thing I would suggest is make sure you have crda installed and your regdomain for your country set.

It has been posted that the pi can not use all 5G channels (The higher ones) and people have to make their router use a lower channel. Seems like maybe channel 6 if I remember right people set.

iw list showed all 5GHz channels configured, so I didn’t need to install crda and set regdomain. I switched the router to use a lower frequency (in this case 5220 MHz [44]) and 5Ghz was available and works. 5GHz was not listed as available when a higher frequency was in use. I couldn’t locate documentation saying what the RPi4 limitation is for 5GHz channel/frequency.

A combination of nano /etc/conf.d/wireless-regdom and uncommenting the WIRELESS_REGDOM=“US”, and setting my 5GHz bandwidth to a lower frequency (55 in my case) solved this for me.
