Failed to parse WPA/RSN IE

[Joo Aun Saw]

Hi,

I'm trying to setup a WPA2 access point with hostapd and madwifi. When my station tries to associate with the access point, I get this error message "Failed to parse WPA/RSN IE from ..." before it tries to exchange keys, so WPA2 mode is not working for me. WPA1 is working for me. Another error I noticed is this "ioctl[IEEE80211_IOCTL_DELKEY]: Invalid argument". I don't know what caused those errors, and can't seem to get any useful information from the internet. Does anyone know how to fix it? Any help greatly appreciated.

Here's my hostapd.conf file:
bridge=br0
interface=ath0
driver=madwifi
logger_syslog=-1
logger_syslog_level=3
logger_stdout=-1
logger_stdout_level=3
debug=0
ctrl_interface_group=0
macaddr_acl=0
deny_mac_file=/etc/hostapd.deny
auth_algs=3
eapol_key_index_workaround=0
eap_server=0
dump_file=/tmp/hostapd.dump
ssid=myTestAP
wpa=2
wpa_passphrase=A_Secret_Password
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP CCMP

Here's a log from hostapd:
