Comment 9 for bug 1419464

> wpa_supplicant is used for all types of encryption, including WEP, WPA,...

Ah, okay then.

> Can you do "sudo ifconfig wlan0 up" and right after that a "sudo wpa_cli -i wlan0 status; echo $?" to be sure? Thx :-)

Yes, of course:

~~~
$ sudo ifconfig wlan0 up
$ sudo wpa_cli -i wlan0 status;echo $?
Failed to connect to non-global ctrl_ifname: wlan0 error: No such file or directory
255
$ sudo ifconfig wlan0

I tried it with wicd service stopped and running, both times the same.
I tried what happens when the downgraded wicd is installed and when the wlan is not connected, I get the same:

~~~
$ sudo ifconfig wlan0

However, when the wlan is connected, by clicking "Connect" in wicd-client first (which works with the downgraded version), I get:

~~~
$ sudo ifconfig wlan0
wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

So the error before connecting is basically the same...
