Just to make sure that the problem originally reported at
http://lists.shmoo.com/pipermail/hostap/2005-July/010790.html is not
because of some mysterious doing of Win-XP supplicant, I compiled and
installed wpa_supplicant on a Linux 2.6.9 laptop and tried to authenticate
with the *802.11a/b/g Madwifi AP* with the same PCMCIA (that didn't work
on Win-XP).
wpa_supplicant compiled and ran fine, but seems to be doing nothing much
more. Here's some output...
zagreb:~# iwconfig ath0
ath0 IEEE 802.11a ESSID:"apsol54"
Mode:Managed Frequency:5.22 GHz Access Point:
00:0B:6B:34:37:0F

Link Quality=0/94 Signal level=-95 dBm Noise level=-95 dBm Rx
invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx
excessive retries:0 Invalid misc:0 Missed beacon:0
... which may be saying that the madwifi driver and hostapd didn't yet
associate to each other. Am I correct in this conclusion?
I had MADWIFI enabled in .config file for compiling wpa_supplicant.
# Driver interface for madwifi driver
CONFIG_DRIVER_MADWIFI=y
# Change include directories to match with the local setup
# CFLAGS += -I/usr/src/madwifi/wpa
The CFLAGS... is commented out because I don't have such a directory
(./wpa) in my madwifi source directory.
Some of the output on screen on running /usr/sbin/wpa_supplicant is:
zagreb:~# wpa_supplicant -i ath0 -c /etc/wpa_supplicant.conf -D madwifi -d

Sorry for the verbose output, but thought I'd provide all the data that
maybe useful.
What am I doing wrong. What else should I try?
Thanks
