WiFi configuration in FreeBSD (including WPA/WPA2) [25/Jan/2010]   NDIS WiFi Drivers in FreeBSD (Project Evil)     RAID5/6 (using ZFS) in FreeBSD 8.x  

Ok, once you have your drivers installed for your WiFi in FreeBSD, you're ready to setup your WiFi.  I'm using an NDIS driver (see my post on Project Evil for more info) – so my wireless device is called ndis0.

I'm going to assume that you are using WPA/WPA2 and DHCP (the most common setup for WiFi) in this document.

To configure your wireless interface, add the following lines into /etc/rc.conf:

ifconfig_wlan0="WPA DHCP" Copy

Now we need to configure the WPA/WPA2 settings.  I will assume we have 2 wireless networks for this – "wifi1" and "wifi2" which have the WPA/WPA2 keys of "one" and "two" respectively.  We will prefer to connect to "wifi1" when possible.

To setup WPA/WPA, edit (or create) the file /etc/wpa_supplicant.conf and add the following:


} Copy

Next time you restart your computer, you will have a 'wlan0' interface which will attempt to connect to the listed networks (in order of priority).  You can confirm it is associated with ifconfig wlan0 – in my case, i get:

wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ether xx:xx:xx:xx:xx:xx
        inet netmask 0xffffff00 broadcast
        media: IEEE 802.11 Wireless Ethernet autoselect mode 11g
        status: associated
        ssid wlan1 channel 7 (2442 Mhz 11g) bssid yy:yy:yy:yy:yy:yy
        country US authmode WPA2/802.11i privacy OFF txpower 0 bmiss 7
        mcastrate 0.5 mgmtrate 0.5 scanvalid 60 protmode CTS roaming MANUAL
        bintval 0 Copy

Now, although it says "11g", it actually achieves 802.11n speeds so you can ignore this.
