I currently trying to get NM to handle a "virtual" wlan device and can't
get it to work. Its the second connection of an Intel 7260, the first
one being used as an access point managed outside of NM.

The OS is an Ubuntu Server 12.04 running NM
uname: 3.13.0-43-generic #72~precise1-Ubuntu SMP i686 i386

When I do everything manually through ip/iw/iwlist everything works fine
but I now need to integrate it with the rest of our software that
handles the network configuration using NM via DBus.

Some quick things that I can think of:

1) rfkill - what does 'rfkill list' say?
2) wpa_supplicant - is the supplicant running, and was it spawned with
the "-u" option?


I create the iface using the following command:
iw dev wlan0 interface add wlan1 type station

Here's what NM gives me:
$ nmcli dev list iface wlan1

I have "[ifupdown] managed=false" in my NetworkManager.conf and wlan1
does not appear in `/etc/network/interfaces`. Nothing is disabled in

Can someone point me the right direction to get out of this
"unavailable" state?
