Can't connect to 2.4GHz but can connect to 5GHz [FIXED]

Hi there!

I’m having some issues when trying to connect to a 2.4GHz WiFi network. I’ve tried with the AP which I know works in my home and even made a hotspot with my phone, alas to no avail. I am successfully connecting to a 5GHz network but 2.4 is a no-go.

I’ve disabled (and re-enabled) random MAC scanning with:

[device]
wifi.scan-rand-mac-address=no

in /etc/NetworkManager/conf.d/disable-random-mac.conf and even tried to disable IPv6 on the 2.4GHz network.

I also tried downgrading my kernel but the issues still arose.

Here’s my journactl -f (ignore the WiFi joke name):

Currently running kernel with uname -r:

5.10.59-1-MANJARO

I have the same problem on my pc.

Okay I fixed this!

Basically the wifi backend needs to be changed from wpa_supplicant to iwd.

sudo pacman -S iwd

then create this file: /etc/NetworkManager/conf.d/wifi_backend.conf and write in:

[device]
wifi.backend=iwd

Then just set the services:

sudo systemctl stop wpa_supplicant
sudo systemctl disable wpa_supplicant
sudo systemctl start iwd
sudo systemctl enable iwd
sudo systemctl restart NetworkManager

And with that I was able to connect on both the 2.4GHz and 5GHz connections!
