Hostapd 0.4.2, madwifi and windows xp sp2

Hello all,

I'm trying to set up a WPA enabled AP using madwifi and hostapd. I have 
a XP sp2 client that is able to associate with the network, and hostapd 
seems happy with it, but cannot send or receive any data (ie, no dhcp, 
ping, etc). The curious thing is that hostapd indicates that the client 
is authorized.

Some details:
The card is a netgear atheros pci card (PCI ID 168c:0013 rev 01), and 
works just fine with madwifi in WEP mode. I've used this card in managed 
mode for some time with WEP and its worked well.
Using hostapd 0.4.2 from debian unstable
Madwifi from CVS (I cant seem to build hostapd against madwifi from CVS)
XP Client has a broadcom card and has SP2 installed- so WPA support 
should be enabled.

The details from my hostapd.conf file:

 interface=ath0
 driver=madwifi
 logger_syslog=-1
 logger_syslog_level=2
 logger_stdout=-1
 logger_stdout_level=2
 dump_file=/tmp/hostapd.dump
 ctrl_interface=/var/run/hostapd
 ctrl_interface_group=0
 eapol_key_index_workaround=0
 macaddr_acl=0
 auth_algs=3
 ssid=the matrix
 wpa=1
 wpa_passphrase=password
 wpa_key_mgmt=WPA-PSK
 wpa_pairwise=TKIP
 wpa_group_rekey=600


Below is the output from hostapd -dd hostapd.conf.
 
Thanks in advance for any help!
