Problems with WPA-PSK and madwifi driver

Hello

I have the following setup:
a) wireless router airplus 315W - WPA=PSK - Channel 11
b) notebook with a WG511T (Netgear).

The notebbok is dual boot machine with Windows XP (wireless works just fine) 
and mandrake 10.1.

I have downloaded and installed madwifi (wlan, ath-pci and ath_hal modules) 
and also wpa_supplicant.

The wpa_supplicant.conf is as follows:

# Same as previous, but request SSID-specific scanning (for APs that reject
# broadcast SSID)
network={
        ssid="eacghome.airlink"
        scan_ssid=1
        psk="klklklklklklkl&&^^klklklklklklklklklklkl"
        priority=2
}

To start device ath0 I have typed

/sbin/ifconfig ath0 up
/sbin/iwconfig ath0 channel 11
/usr/sbin/wpa_supplicant -c/etc/wpa_supplicant.conf -Dmadwifi -iath0 -d

Here is part of the ouput

Ath0 doesn't get a valid ip address.  

What am I doing wrong?  Have I missed something?

Many thanks
