"Unsupported TKIP Group Cipher key length"

[Eric]

Hi,
  I'm trying to get WPA working on my Livebox modem/router and a
madwifi card + wpa_supplicant.

I'm getting these messages from wpa_supplicant:

State: GROUP_HANDSHAKE -> GROUP_HANDSHAKE
WPA: RX message 1 of Group Key Handshake from 00:0e:9b:99:1a:38 (ver=1)
WPA: Unsupported TKIP Group Cipher key length 13 (13).
RX EAPOL from 00:0e:9b:99:1a:38
IEEE 802.1X RX: version=1 type=3 length=108
  EAPOL-Key type=254

(looping three times before terminating)

I haven't been able to find any info on this type of error. Is it the
client or the AP's fault?

Ciao.

PS: I'm using wpa_supplicant 0.4.0 and madwifi cvs-2005-05-31.
