Association fails both with WEP and 'no key'.

It's just like old times... NetworkManager destroys the possibility to connect. If you service NetworkManager stop it and restart wpa_supplicant by hand, here at least it works. I had it turned off anyway.

But there is another bug in mac80211 or iwlwifi... when iwlwifi registers its capabilities with mac80211, the order matters. As it stands, iwlwifi will only connect at 802.11b speeds, ie, 11Mbps. If you swap the order of the registration:

diff -urN iwlwifi-0.0.8-orig/compatible/base.c iwlwifi-0.0.8/compatible/base.c
--- iwlwifi-0.0.8-orig/compatible/base.c	2007-02-25 17:56:44.000000000 +0000
+++ iwlwifi-0.0.8/compatible/base.c	2007-02-25 09:33:43.000000000 +0000

 	priv->status |= STATUS_GEO_CONFIGURED;
 }

then you get 11g speeds.
