NetBSD mars 4.99.3 NetBSD 4.99.3 (MARS) #0: Thu Sep 28 20:44:21 CEST 2006  root@mars:/usr/src/sys/arch/i386/compile/MARS i386
Then trying to connect to AirPort Extreme card (in PowerMac G5) using iwi0 (Intel WiFi) interface with WEP encryption enabled, the console displays "iwi0: unknown authentication state 4" as long as the interface is UP.

The connection works perfectly well when:
1. encryption is disabled on AirPort Extreme
2. AirPort (non-Extreme) card is providing connection (I use AirPort in PowerBook G4)

Note: I am using iwi-firmware-2.3nb1 package. 3.0 version is available here
Try to set up an encrypted connection between Intel WiFi interface and Apple AirPort Extreme.

 The problem still exists in NetBSD 4.99.72.

 sys/dev/pci/if_iwi.c, line 2585:
 if (ni->ni_authmode == IEEE80211_AUTH_SHARED)

 at this point, ni->ni_authmode is set to IEEE80211_AUTH_OPEN (1),
 althought iwi has nwkey set (104-bit encryption) and the driver should
 authenticate with a password

 when I commend this line out, iwi driver works correctly with my network

 Please, advice.
