Recent version partially implements WPA-TKIP with wpa_supplicant. You
need a running wpa_supplicant installation with a
/etc/wpa_supplicant/wpa_supplicant.conf file. Then by setting
"use_wpa = yes" in your /etc/wifi-radar/wifi-radar.conf file and
"wpa_driver = ipw" for example, wpa_supplicant will be launched using
the ipw driver (ipw2100 or ipw2200) when you connect using this
profile.
But currently you can't set wpa_supplicant options like psk,
proto, key_mgmt etc. dynamically, i.e using wifi-radar. Your wpa_supplicant
configuration file should be set and tested already. But if you have
different networks set in wpa_supplicant.conf, then you can switch using
wifi-radar.
In the above example any option but "wpa" options can be set manually.
