I have to remember to move wpa_supplicant back after I stop
using hostapd .
Please add support for enabling either hostapd or wpa_supplicant,
not both, to NM = or is there some way of disabling running the
wpa_supplicant service only, without rfkill ?


configure the device as unmanaged.

Temporarily, with `nmcli device set wlan0 managed no`

Permanently, there are several means (udev rules, config files). the
best seems to be a file




see `man NetworkManager.conf`.

If you do it that way, you can still override it at runtime with `nmcli
device set wlan0 managed yes`.

I think `nmcli device set wlan0 managed yes` may not sufficiently
instruct wpa_supplicant to let go of the device. That means, you still
might need `systemctl stop wpa_supplicant.service`. Patch welcome to
properly handle the release of a device by setting it unmanaged.

Good day -

 Whenever I try to run hostapd, NM still runs wpa-supplicant,
 which periodically tries to put the WiFi interface into scanning
 mode, which messes up the hostapd session .

 Please is there a config file setting or applet interaction
 to disable wpa-supplicant (and maybe configure & run hostapd) ?

 I'd like NM to start dhclient on my Wired interface, and
 be able to bring up my L2TP VPN, but leave the Wireless
 interface entirely alone.

 Any way to do this in NetworkManager.conf or GUI ?

Thanks in advance for any replies,
