I'm trying to setup my laptop for wireless access. I have a dell inspiron 6400 with intel ipw3945 wireless adapter. I managed to get the adapter to work. At least iwconfig gives a sensible output and "iwlist scan" allows me to see the wirless network. The problem is how to connect? Authentication type is TTLS and encryption type PAP. I've also been supplied with a radius server address and .crt certificate. I understand wpa_supplicant supports this authentication type but I can't get it to work. Here is my setup

wpa_supplicant version: 0.4.9
Kernel: Fedora 2.6.16-1.2122_FC5smp i686

The specific command I am using is
# wpa_supplicant -c /etc/wpa_supplicant.conf -i eth1 -D ipw

and the output is "No driver interfaces build into wpa_supplicant".

I installed wpa_supplicant using the commands
#make
#make install
#cp wpa_cli wpa_supplicant /usr/local/bin

and got no errors.

I have the following in my .config file
CONFIG_IEEE8021X_EAPOL=y
CONFIG_EAP_MD5=y
CONFIG_EAP_MSCHAPV2=y
CONFIG_EAP_TLS=y
CONFIG_EAP_PEAP=y
CONFIG_EAP_TTLS=y
CONFIG_EAP_GTC=y
CONFIG_EAP_OTP=y
CONFIG_EAP_SIM=y
CONFIG_EAP_AKA=y
CONFIG_EAP_PSK=y
CONFIG_EAP_PAX=y
CONFIG_EAP_LEAP=y
CONFIG_WIRELESS_EXTENSION=y
CONFIG_DRIVER_HOSTAP=y
CONFIG_DRIVER_ATMEL=y
CONFIG_DRIVER_WEXT=y
CONFIG_DRIVER_NDISWRAPPER=y
CONFIG_DRIVER_IPW=y

My wpa_supplicant.conf file contains

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
network={
key_mgmt=IEEE8021X
eap=TTLS
identity="my username"
password="my password"
ca_cert="location of .crt file"
phase2="auth=MD5"
}


I've spent ages searching the web for information so any help would be appreciated.

Dave
