looks like for some reason your devices come in a different order to mine, and that is causing this error. unfortunately there is no simple way to tell whether a given interface is wifi or not, so we'll have to pattern match the interface names.

this is a bit ugly, but maybe the only way to pick the right interface automatically.

I had the same problem so I always use INTERFACE= and it works. Interface order is distro related. I use archlinux and interface order vary from time to time :dancer:

@vvo can you post the output of ip -o link on your system?

Oh yeah and there's no "wlan0" :D

@vvo it looks like this should work. when i originally wrote this, i used it with a usb key (because I had an hp with bcom chipset that had bad driver support). I can't remember what the interface was called but it was something different. I think it did start with "w" at least, if not "wl"
