Hello everybody,

I changed the MAC address(with ifconfig wlan0 hw ether) of my wireless 
interface Intel to do a little experiment (Link aggregation) but 
suddenly my wireless NIC doesn't work anymore. I rebooted my Ubuntu 
12.10, also the interface has the original MAC again and still doesn't 
connect to any SSID. wpa_cli shows me:


<3>SME: Trying to authenticate with 00:21:29:92:e9:a5 
(SSID='LAB_Wireless' freq=2462 MHz)
<3>Trying to associate with 00:21:29:92:e9:a5 (SSID='LAB_Wireless' 
freq=2462 MHz)

The reason 3 is when the network manager ask me again for the password 
of the SSID, and do the same process to all the available wifi networks 
without establish connection. The reason 15 I don't know what means. 
What's going on ? What i'm doing wrong?


thanks in andvance.
