madwifi_process_wpa_ie: Failed to get WPA/RSN IE

Tue Jan 5 19:16:05 PST 2010

Hi:
I am using madwifi(0.9.4-r4100-20090929)+hostapd(hostapd-0.6.9)+kernel(
2.6.30.5) in ixp425 for Atheros AR5213a CM9-GP on mini-PCI.
I try to connect from a PC client to the AP running hostapd and madwifi with
WPA with PSK, but the PC failed to connect to it.
If I run hostapd with no encryption method ,then it works well. I don't know
why.

I also changed to use kernel with 2.6.21(or 2.6.24) and madwifi driver
released 0.9.4 , but it still couldn't resolve my problem, the same error
message.

I don't know why, is there a problem with my card(Atheros AR5213a CM9-GP) or
my config file(hostapd.conf or .config in hostapd when compiling) or
something else?

Who can  help me with this problem? Thank you!

Here is some of my message, hope to help you:

=============================================================
We can see error is comming from ioctl call in driver_madwifi::set80211priv
for
op-code IEEE80211_IOCTL_GETWPAIE
This is defined in madwifi code /net80211/ieee80211_ioctl.h as
SIOCDEVPRIVATE+4. SIOCDEVPRIVATE is defined in linux/include/sockios.h
as 0x89F0.

Thanks for your help.
