Hi again,
I'm sorry to tell you this again, but I still have big problems with wpa_supplicant when I try to connect to an accesspoint which is behind a wall or under the roof (or on another place where the SNR is under 25 or weaker) which was always possible with the stable madwifi 0.9.3.2/3).
I'm still using ALIX/WRAP boards with voyage images, now with kernel 2.6.24, hostapd 0.5.9 and wpa_supplicant 0.5.9 and SR2/CM9/Sparklan abg cards.
The supplicant trys to connect, but my ap always gets blacklisted by the supplicant. I tried all typs of wirelesscards I had, but with every card I tried I got the same trouble.
Then I tried an old image of mine with 0.9.3.2 stable and 2.6.21-7 kernel as client with wpa_supplicant 0.5.8 and it worked. It also worked with all of my wireless devices in the office: macbook, Imac, atheros cards in Windows-PCs etc pp. They all could connect without interference.
I discovered this behavior of wpa_supplicant since I tried a few trunks after I had these ugly kernel-panics with 0.9.3.3 with "wpa_supp and hostapd together in a bridge". With all the trunks I used I had the same troubles with weak SNR rates with wpa_supplicant and this dumb blacklisting-stuff.
Last point: If I do not use encryption, the client associates imediatly, but after I send few data-packages (iperf) the device gets down (ath0 entering disabled state) and it does not go into enabled state.
My script (it builds a chain of nodes (always ap/sta <-> ap/sta <-> ap/sta <- )) :
killall hostapd
killall wpa_supplicant
ifconfig br0 down
brctl delbr br0
echo 1 > /proc/sys/net/ipv4/ip_forward
#madwifi neu laden
rmmod ath_pci
modprobe ath_pci
#wifi0 hochfahren als sta
wlanconfig ath0 create wlandev wifi0 wlanmode sta
iwconfig ath0 essid strecke1
ifconfig ath0 0.0.0.0 down
iwpriv ath0 wds 1
ifconfig ath0 0.0.0.0 up
#wifi1 hochfahren als ap
wlanconfig ath1 create wlandev wifi1 wlanmode master
iwconfig ath1 essid strecke2
iwconfig ath1 channel 52
ifconfig ath1 0.0.0.0 down
iwpriv ath1 wds 1
ifconfig ath1 0.0.0.0 up
#eth0 einschalten
ifconfig eth0 0.0.0.0 up
#bridging
brctl addbr br0
brctl addif br0 ath0
brctl addif br0 ath1
brctl addif br0 eth0
brctl setfd br0 1
#bridge hochfahren
ifconfig br0 192.168.2.22 up
hostapd -B /etc/hostapd/hostapd.conf
sleep 1
wpa_supplicant -B -i ath0 -D madwifi -b br0 -c /etc/wpa_supplicant/wpa_supplicant.conf
