wpa supplicant + ndiswrapper authentcation problem

I'm using ndiswrapper with wpa supplicant support, with ndiswrapper is all ok.

wg311v2 : driver installed
    device (104C:9066) present
wlan0     IEEE 802.11g  ESSID:off/any  
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated   
          Bit Rate:54 Mb/s   Tx-Power:10 dBm   Sensitivity=0/3  
          RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

A strange thing or not maybe, is that i cannot modify wlan0 parameters, for example if i use:

iwconfig wlan0 essid "WCB"

The ESSID parameter remains:off/any. Maybe is a limititaion of the wrapper, am i wrong ?

when i launch wpa_supplicant with this parameters:

wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_support.conf

Using this configuration:

ctrl_interface=/var/run/wpa_supplicant
eapol_version=1
ap_scan=1
fast_reauth=1

network={
        ssid="WCB"
        key_mgmt=WPA-PSK
        proto=WPA
        pairwise=TKIP
        group=TKIP
        psk="XXXXXX"
        priority=9
}

i got this output:

ioctl[SIOCSIWPMKSA]: Invalid argument
ioctl[SIOCGIWSCAN]: Resource temporarily unavailable

i don't understand this error... hmm

Re: wpa supplicant + ndiswrapper authentcation problem

I've used some debugging output and i descovered this message:

wpa: drop TX EAPOL in non-IEEE 802.1X mode (type=1 len=0)

Maybe a problem with the key ? or with the transmission of the key ?
This message compare every time that wpa_supplicant is "handshaking" with the router.

thanks for your attention.

Re: wpa supplicant + ndiswrapper authentcation problem

Thanks for your reply. I don't get it what exactly network manager is, i'm not using it, i don't have install it, i'll try to install it and see if something change.
Yeah i got ndiswrapper installed using the pacman procedure and i launch the module at boot but i launch the connection manually, i got it to work only two times in a week, i don't know how or why, i've did always the same procedure.

i've read that with the new version of ndiswrappper using the wext driver is raccomended, and -Dndiswrapper is for older ndiswrapper versions.

using -Dndiswrapper i got

ioctl[SIOCSIWPMKSA]: Invalid argument
Trying to associate with SSID 'WCB'
Association request to the driver failed
Authentication with 00:00:00:00:00:00 timed out.

Re: wpa supplicant + ndiswrapper authentcation problem

Ok, maybe i'm starting to understanding something more:

The problem is on the 4 way handshake procedure:

1-Card -> Router
2-Router -> Card
3-Card -> Router
4-Router -> Card

The fourth EAPOL key from router to card is zero, i don't know why, but is unvalid. And the procedure restart again, i've done some scanning also with wireshark.

In this week i got the wifi connected only two times, the time that worked i've saved a log:

Apart this two incredible exceptions, i got always this message just after the group_handshake:

Hope i find something else soon...
