I'm trying to force my wifi card to connect over the G-band as per this question. However, when I run
iwconfig, I am told the resource is busy:
[root@Eiger ~]# iwconfig wlan0 freq 2.422G SET failed on device wlan0 ; Device or resource busy
I'm pretty sure this is because NetworkManager is running. However, when I try to stop it, it just respawns again. I've tried stopping it through
systemctl stop and
kill. How can I permanently turn off NetworkManager in Gnome 3?
