"[PATCH] iwlwifi: fix oops on wep key insertion" 27/5/2008

invalid length of webkey that would/should be handled in mac80211?

Yes, it looks like.
Ummm, what has a wep key to do with me trying to access a WPA2-Personal
encrypted net ?
Not sure yet, but mac is trying to assign default/static wep key.

:iwlcore:iwl_send_static_wepkey_cmd+0xcb/0xd5
:iwlcore:iwl_set_default_wep_key+0xa2/0xbc

Try to set the encryption explicitly
network={
psk="*************************"
scan_ssid=1
ssid="dlink"
pairwise=CCMP
group=CCMP
}


That didn't help at all...

What's more it prevented the wifi to work on 2.6.24.7 so I had to remove the
lines again...

So what's your AP configuration TKIP?

Yeah, the supplicant log he posted clearly shows that the GTK is TKIP.

1212763152.516790: WPA: Key negotiation completed with 00:xx:xx:xx:xx:xx [PTK=CCMP GTK=TKIP]


The AP is actually set for TKIP+AES

BTW, is that better or worse than a clean AES ?
I'm reading up on it, but I get a lot of conflicting info...

Dan

Second try also with sw decryption:

in /etc/modprobe.conf
options iwl4965 swcrypto=1
