===== Replacing iwconfig with iw =====

Consider using iw from git 


==== Getting info on wlan0 ====


<code>iwconfig wlan0</code>
is be replaced by 


<code>iw dev wlan0 link</code>

==== Connecting to an open network ====


<code>iwconfig wlan0 essid foo</code>
is replaced by 
<code>iw wlan0 connect foo</code>
If you want to set the channel: 
<code>iwconfig wlan0 essid foo freq 2432M
-or-
iwconfig wlan0 freq 2432M
iwconfig wlan0 essid foo</code>
you instead simply use 
<code>iw wlan0 connect foo 2432</code>

==== Connecting to a protected network ====

For WPA/WPA2 encryption, you have to use wpa_supplicant. 

For WEP protection, you can use 
<code>iw wlan0 connect foo keys 0:abcde d:1:0011223344</code>
instead of 
<code>iwconfig wlan0 key s:abcde
iwconfig wlan0 key '[2]0011223344'
iwconfig wlan0 key '[2]'
iwconfig wlan0 essid foo</code>
Note that <code>iwconfig</code> uses 1-based key numbers and <code>iw</code> uses 0-based key numbers like the 802.11 standard. 


==== Join an IBSS (ad-hoc network) ====


<code>iwconfig wlan0 mode ad-hoc
iwconfig wlan0 essid foo-adhoc</code>
in iw: 
<code>iw wlan0 set type ibss
iw wlan0 ibss join foo-adhoc 2412</code>

==== Leave an IBSS (ad-hoc network) ====


<code>iwconfig wlan0 essid off</code>
**might** work, but doesn't always work properly. 

in iw, it will always work: 
<code>iw wlan0 ibss leave</code>
