i habe tried iw but it doesn't work too:
1) first i have used iw
0.9.4-nogit there is many options not supported so i could not find out
how to set the adhoc mode so i upgraded to new version 0.9.21
2) Using the new version i have tried two methods but both failed:
*) ifconfig wlan0 down
iw --debug dev wlan0 ibss join fooadhoc 2412
