So, your AP is fully open, right ?

Ok, I would need 2 console outputs from you:
1) The output of "iwlist wlan0 scan", before running wpa_supplicant.
2) The output of "wpa_supplicant -dd -Dwext -ieth0 -c/etc/wpa_supplicant.conf"
Note the additional -dd compared to your command line. This will give us
plenty of debug from wpa_supplicant.

It's a buffer we received from the firmware, containing BSSI data. For some
reason (most likely a huge number of IEs), it's too big to be sent to

One more question: when you run wpa_supplicant, you keep on getting those
scan completew events, but it never actually associates with your AP ? Did
I understand you right ?
