wpa_supplicant connects but can't get IP?

I had an old WEP router which I was using fine with iwconfig until recently where I replaced it with a WPA2-PSK version. I switched to wpa_supplicant and it seems to connect OK but I simply can't retrieve an IP address from the router. Manually assigning a valid IP doesn't put me on the network either so I guess it's something I'm doing wrong with the connection.

My wpa_supplicant.conf looks like this:

network={
ssid="edddwire"
scan_ssid=1
key_mgmt=WPA-PSK
psk="FFFFFFFFFF"
}

It associates fine if I run:
wpa_supplicant -Dwext -ieth1 -c/etc/wpa_supplicant/wpa_supplicant.conf
Trying to associate with 00:FF:FF:FF:FF (SSID='edddwire' freq=0 MHz)
Associated with 00:FF:FF:FF:FF
WPA: Key negotiation completed with 00:FF:FF:FF:FF [PTK=CCMP GTK=TKIP]
CTRL-EVENT-CONNECTED - Connection to 00:FF:FF:FF:FF completed (auth)

wpa_cli reports:
> status
bssid=00:FF:FF:FF:FF
ssid=edddwire
pairwise_cipher=CCMP
group_cipher=TKIP
key_mgmt=WPA2-PSK
wpa_state=COMPLETED

But this error appears every now and then:

ioctl[SIOCGIFADDR]: Cannot assign requested address

The wireless card is a ipw2200. Anyone have any ideas? Thanks in advance..

Since you have a ipw2200, is the firmware installed in the /lib/firmware directory ?? Are you using static ip or dhcp ?? If using DHCP and runnning from the cli, once the supplicant connects your have to open a terminal window su - (su dash) and type:

dhclient eth0 or eth1, whatever your wireless device is named...


But let's make it easy, verify the firmware is installed, then turn on the NetworkManager services, and turn off the wpa_supplicant service if it's running and save the changes, reboot the computer, left click on the new icon in the top panel and select your AP, it should ask for the "default keyring" password, then ask for your wpa2 key....
