Why wpa_supplicant does not connect to a -61dbm access point?

[Jörg Sommer]

Hi,

I've an Airport Extreme card (bcm4306) and I use wpa_supplicant 0.5.7
with a Debian unstable on PowerPC. My config is available at
http://www.uni-jena.de/Linux_Fedora_Core___Scientific_Linux_4_x_mit_WPA_EAP_TTLS_PAP.html

Why is it 00:00:00:00:00:00?

Does wpa_supplicant understand the "authenticated" event?

What goes wrong? Why wpa_supplicant does not connect to the network? Do
you need more informations? Which?

Bye, Jörg.
