airport extreme with linux-2.6.18

[William <william.xwl@gmail.com>]

Hi folks,

I've been struggling days to try making airport extreme work, only in
vain..At present, it could scan wireless network successfully. And
this is how i do it:

# iwlist eth1 scan
# iwconfig eth1 essid "A213"
# iwconfig eth1 rate auto
# iwconfig eth1 key off
# dhclient eth1

The last step never succeeds:

,----[ dhclient  eth1 ]
