[SOLVED] Wifi device don't stay down after `ip link set wlan0 down`

Hello,

I have 2 wifi devices on my computer, and I wan't to disable the wifi from the motherboard.

The command `ip link set wlan0 down` is working, but after a few minutes the device is UP again.

I have only the NetworkManager.service being enabled.

Anyone have an idea about this issue ?

Thanks in advance.

Good day,

You could try putting this in your NetworkManager.conf

[main]
plugins=keyfile

[keyfile]
unmanaged-devices=interface-name:wlan0

Thank you Julia, It's working.

After changing the file '/etc/NetworkManager/NetworkManager.conf' like you said, then a `systemctl restart NetworkManager` and `ip link set wlan0 down`.
The interface wlan0 stay down.
