hostapd and madwifi don't work well

Sun Mar 19 19:55:01 EST 2006

hi list, well i'd like report problems i'm having with madwifi and hostapd.
first of all i had to upgrade to etch from sarge to get last libraries needed to compile hostapd, in other way it was impossible, trying to install them alone get my system totally unstable.
well after upgrading and installed whole libraries needed, i compiled madwifi-ng-r1475, everything was ok, my clients could connect and work very well by hours, no problem.
so wanted to add security, decided to use hostapd, i really want tls but for testing purposes decided start only with psk, so compiled hostapd-0.5.1, i could do this: 

make clean
make
make install

but any file was copied to system, so copied hostapd.conf from madwifi docs and try to work, i could start program and clients try to connect, even get connection by 2 seconds at intervals, but never get total connection, always stay in "Aquiring network address" and i get this from hostapd:

Ethereal always shows MDS HEADER MALFORMED PACKET.

so decided try with hostapd-0.4.8, and now get this:

ioctl[unknown???]: Invalid argument

clients of course cann't connect and always stay in "Aquiring network address"

finally decided to try with hostapd-0.5.1.deb, now get this:

www:/home/server# /etc/init.d/hostapd start
Starting advanced IEEE 802.11 management: hostapdioctl[unknown???]: Argument list too long
...failed.

www:/home/server# hostapd -dd /etc/hostapd/hostapd.conf

Deauthenticate all stations
madwifi_set_privacy: enabled=0
madwifi_set_ieee8021x: enabled=0
madwifi_set_iface_flags: dev_up=0

nothing happens, nothing works.

so decided back to initial configuration, without hostapd, but now clients disconnect each 10 minutes, so something is wrong with my system, but what?? with first implementation clients showed successfull wlan connection icon (winxp), now, they are connected but icon shows they are not, and ethereal shows MDS MALFORMED PACKET.

so two questions:

1) what should i do to get my system again working well, as first implementation?? i deleted everything related with hostapd.  should i reinstall whole system? Please tell me it's not necessary!!
2) why hostapd and madwifi aren't talking each other??

this is my hostapd.conf file:

interface=ath0
driver=madwifi
logger_syslog=-1
logger_syslog_level=2
logger_stdout=-1
logger_stdout_level=1
debug=0
dump_file=/tmp/hostapd.dump
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
ssid=MYWLAN
macaddr_acl=0
auth_algs=1
wpa_passphrase=mywlan
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP 

ok, i know it's a huge e-mail, excuse me, i hope some charitable soul could help me.

thanks in advance for your patience.
