Installing wpa_supplicant with madwifi support

• Get the source wpa_supplicant
• Edit .config

.config

 CONFIG_DRIVER_MADWIFI=y
 # Change include directories to match with the local setup
 CFLAGS += -I../madwif
 CONFIG_DRIVER_WEXT=y
 CONFIG_IEEE8021X_EAPOL=y
 # EAP-MD5 (automatically included if EAP-TTLS is enabled)
 CONFIG_EAP_MD5=y
 # EAP-MSCHAPv2 (automatically included if EAP-PEAP is enabled)
 CONFIG_EAP_MSCHAPV2=y
 # EAP-TLS
 CONFIG_EAP_TLS=y
 # EAL-PEAP
 CONFIG_EAP_PEAP=y
 # EAP-TTLS
 CONFIG_EAP_TTLS=y
 # EAP-GTC
 CONFIG_EAP_GTC=y 
 # EAP-OTP
 CONFIG_EAP_OTP=y
 # LEAP
 CONFIG_EAP_LEAP=y
 # PKCS#12 (PFX) support (used to read private key and certificate file from
 # a file that usually has extension .p12 or .pfx)
 CONFIG_PKCS12=y
 # Include control interface for external programs, e.g, wpa_cli
 CONFIG_CTRL_IFACE=y

• install wpa_supplicant by make && make install

Configuration for WPA-PSK

• Edit wpa_supplicant.conf

wpa_supplicant.conf

 ctrl_interface=/var/run/wpa_supplicant
 ctrl_interface_group=0
 eapol_version=1
 # ap_scan=2 was the one for me you may try 0 or 1 indstead of 2
 ap_scan=2
 fast_reauth=1

 network={
       ssid=""
       proto=WPA
       key_mgmt=WPA-PSK
       pairwise=TKIP
       group=TKIP
       psk=
 }

You have to change the values according to the response of "wpa_passphrase yourAPssid yourpassphrase ".

Starting wpa_supplicant

Now you are able to start wpa_supplicant by "wpa_supplicant -d -c/etc/wpa_supplicant.conf -iath0 -Dmadwifi ". If every thing works as expected, you can replace -d by -B for the deamon mode.

At the moment I bring up my network card manual by "ifconfig ath0 ip up" and changing the routes and add the default gateway.
