Ignore the above loop thing. The cause seems to be this one instead.


# this needs patch to work ...
iwconfig wlan0 mode Managed
ifconfig wlan0 up
iwconfig wlan0 essid xxx
iwconfig wlan0 key restricted xxx
iwconfig wlan0 ap auto channel auto


# this works with patch ...
iwconfig wlan0 mode Managed essid xxx key restricted xxx
ifconfig wlan0 up
iwconfig wlan0 ap auto channel auto

It looks the placement of "ifconfig" matters. But works on 2.6.28-rc3.


Thanks,
Jeff.
