Well, it seems I was pretty wrong! I have downloaded the lastest CVS snapshot from your web page. I have compiled only the hostapd module. When I try to execute it happens the next:

[root_at_victor]# ./hostapd wlan0
ioctl(SIOCGIFINDEX): No such device
ioctl[SIOCGIFFLAGS]: No such device

However, it works without problems when I execute the hostapd from my old release version (Prism2-2002-05-19). As I have said, I have installed the version Prism2-2002-05-19 of the driver but I do not thing this is the problem.

Please, let me know if you have any clue!

Thanks a lot,
