I've modified it a little, and now it works 100% without patch, by
using "iwlist scan" instead of "sleep 1" ...
        iwconfig wlan0 mode Managed essid xxx key restricted xxx
        iwconfig wlan0 ap auto channel auto  # auto outside loop
        for((i =3D 0; i < 5; i++))
        do
                iwlist wlan0 scan >/dev/null  #use scan instead of slee=
p
                iwconfig $DEV | grep -q "Access Point: Not-Associated"
                [ $? -ne 0 ] && break
                echo ".\c"
        done


So, this will work for older kernel and well as 2.6.29-rc8.

Rafael, can we close the case? It's the iwconfig sequence that used to
work on 2.6.28-rc3 but now needs to be updated for 2.6.29-rc8.

Thanks,
Jeff.
