It seems that the acces point is found but that association doesn't succeed. I had that I use TKIP as encryption method. I just wanted to know if this is a known bug of the driver or of wpasupplicant and we may hpe that it will be solved when the final release of the 2.6.13 will be released.

I looked for CONFIG_IPW and CONFIG_IEEE80211 but I didn't find anything
in my kernel configuration file. I also opened a bughost.org and Yi Zhu
answered like you that I must use Dwext and it works with that settings.
 I would like to know how to check your 2nd point. Is it the option
"Wireless LAN drivers (non-hamradio) & Wireless Extensions" in kernel
config. Do I have to remove it if I want to use wpa_supplicant with the
-Dipw parameter ? Or is it something else ?

Thanks for your help,
