Authentication timeout with wext driver and ipw3945 card

[Giuliano Pasqualotto]

Hi Dan,
thank you for your reply.

>This could be your problem.  Use ap_scan=1 or ap_scan=2.
I've tried both, and in the first case wpa_supplicant tries to connect
continuously
without results, and in the output I notice this phrase:
     ...
     ioctl[SIOCSIWENCODEEXT]: Invalid argument
     Driver did not support SIOCSIWENCODEEXT
     WPA: Failed to set PTK to the driver.
     ...
In the second case nothing significant seems to happen (well, to me).

For the point (a)... Configuration is correct I hope, anyway,
that's the "iwlist" output:

My kernel is the vanilla 2.6.21.5, the ipw3945 driver is the 1.2.2 (firmware
1.14.2),
and I've built 802.11 stack and mac like a module, during kernel compiling.
I've already enabled debugging for mac, ieee802.11 and ipw driver, tell me
if (and how) I could give you more informations.

Thank you in advance Dan :-)
