wpa_supplicant, madwifi and WEP?

[Gonzalo Diethelm]

Hello, first post here.

I'm using linux 2.6.8 (debian unstable), and my WiFi card is:

0000:00:09.0 Ethernet controller: Atheros Communications, Inc.
AR5212802.11abg NIC (rev 01)

The madwifi driver is from CVS as of today. This is my wpa_supplicant
configuration (the XXX values are there to protect the innocent):

network={
        ssid="XXX"
        scan_ssid=1
        priority=50
        auth_alg=SHARED
        key_mgmt=NONE
        wep_key0=xxxxxxxxx0
        wep_key1=xxxxxxxxx1
        wep_key2=xxxxxxxxx2
        wep_key3=xxxxxxxxx3
        wep_tx_keyidx=0
}

The scan_ssid is there because this network does not broadcast its SSID;
is this the right approach? (At least it did allow me to find the AP and
try to bind to it).

Now, when I run wpa_supplicant in debug mode it does find the AP and it
does bind to it, but the WEP keys are never passed on to the card, and
therefore the card eventually unbinds from the AP. Here is part of the
log I'm seeing:

After that final line, I do a iwconfig on the card and it does show the
correct AP MAC address and ESSID name, but the encryption key is off.

Can anybody give me a hand here? Am I misconfiguring wpa_supplicant? Is
perhaps this mode (WEP with encryption) not supported?

Thanks in advance, and best regards.
