iw dev wlan0 link - "Not connected"

iw dev wlan0 link - "Not connected"

[Zhongliang Zhao]

Dear all,

When I use "iw dev wlan0 link" to get information on wlan0 (basically to 
check the channel used on wlan0),
it says: " Not connected "

Can someone tell me how to fix this?

Many thanks.

Refer to:

http://wireless.kernel.org/en/users/Documentation/iw#Getting_link_status

And then:

http://wireless.kernel.org/en/users/Documentation/iw#Establishing_a_basic_connection

What you really want to use is:

http://wireless.kernel.org/en/users/Documentation/wpa_supplicant

Luis, thanks for the reply. But actually we're working on mesh nodes 
with the iw-tool installed, so maybe we should use the "mesh" interface 
mode. In this case, how to solve the problem?

Thanks, zhongliang

Note for ath9k you currently have to issue a scan to kick the card to
beacon, its a bug, not dealt with yet.
