My AP is a SWEEX wireless modem/router with conexant chipset. The firmware version for WPA is CX_WLANSEC_4.2.0
I have no experience with packet capture... If you really need it I will try to have a look at it but I actually have rare occasions to play with my wireless settings.
I've upgraded madwifi-driver and madwifi-tools to version 0.1_pre20050420 on my gentoo box. I've tried to upgrade wpa_supplicant to versions 0.4.* but I had to come back to stable 0.3.8 as I got other problems (ioctl[SIOCSIWPMKSA]: Operation not supported )

Anyway: a more complete debug log can be found there:
Sorry, it's a bit long, but I don't know what piece of information is the most useful to you... I've left wpa_supplicant running for about 1 minute. It ends when I hit Ctrl-C (l. 1079 in the log, or 8 lines from the end)

The second one is the MAC address of the modem/router (LAN). The first one is the AP:
WLAN Driver(Marconi) : v3.0.5
Boot Loader Version : v3.1.1
Upper MAC Version : M_UM_3.1.20
Lower MAC Version : M2_LM_D2959SC_3.1.41
AP BSSID: 00:05:B4:07:E9:91 

Thanks a million for your help!
