To get wlan working on your Freerunner, you can follow these steps:
1. create and edit a suitable /etc/wpa_supplicant/wpa_supplicant.conf (use your favourite search engine to find the syntax)
2. execute `ifup eth0`
3. execute `wpa_supplicant -ieth0 -c/etc/wpa_supplicant/wpa_supplicant.conf -B` (-B for running as daemon)
4. get a IP via dhcp: `udhcpc eth0`
That's it, your wlan should now work!
Sample wpa_supplicant.conf:
ctrl_interface=/var/run/wpa_supplicant eapol_version=1 ap_scan=1 # WPA2: network={ ssid="your ssid" scan_ssid=1 proto=RSN key_mgmt=WPA-PSK pairwise=CCMP TKIP group=TKIP CCMP psk="secret key" priority=50 } # WPA: network={ ssid="your_ssid" scan_ssid=1 psk="secret key" priority=10 } # WEP: network={ ssid="your_ssid" scan_ssid=1 key_mgmt=NONE wep_tx_keyidx=0 wep_key0="secret key" priority=8 } # Open: network={ ssid="your ssid" key_mgmt=NONE priority=5 }
A very ugly /etc/init.d/wlan startscript:
#!/bin/sh # # wlan This shell script starts and stops wlan. # # processname: wlan # Source function library. #. /etc/rc.d/init.d/functions # "written" by HdR RETVAL=0 prog="wlan" # test -f /etc/default/$prog && . /etc/default/$prog start() { echo -n "Starting $prog: " ifconfig eth0 up wpa_supplicant -ieth0 -c/etc/wpa_supplicant/wpa_supplicant.conf -B sleep 10 udhcpc eth0 RETVAL=$? return $RETVAL } stop() { # Stop daemons. echo -n "Shutting down $prog: " killall wpa_supplicant ifconfig eth0 down # killproc gpsd RETVAL=$? return $RETVAL } # See how we were called. case "$1" in start) start ;; stop) stop ;; restart|reload) stop start RETVAL=$? ;; *) echo "Usage: $0 {start|stop|restart}" exit 1 esac exit $RETVAL
An alternative way to automate adds the wpa_supplicant details to /etc/network/interfaces:
iface eth0 inet dhcp wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
Now `ifup eth0` will start up wpa_supplicant and udhcpc for you, and `ifdown eth0` will stop them, in theory at least. In practise udhcpc can time out before wpa_supplicant has finished connecting to the access point, and if udhcpc has failed to get an address ifdown exits without stopping wpa_supplicant and bringing down the interface.
The second method seems to work reliably on the GTA02, I couldn't get the manual method to work when WPA/PSK is involved. Also you must do ifdown usb0 before the ifup eth0. Then you also need to setup the resolv.conf manually as it does not seem to get the dns server from the dhcp server.
