Add WiFi Connectivity

Connect my pandaboard wifi (STA) to an Access Point.

Create wpa_supplicant.conf if it's not being created.


mkdir -p /etc/wpa_supplicant
sudo nano -w /etc/wpa_supplicant/wpa_supplicant.conf


ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=root
network={
    ssid="ap_name"
    key_mgmt=WPA-PSK
    psk="ap_password"
    id_str="home"
}


Test your wpa_supplicant.conf:
wpa_supplicant -BW -Dwext -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf

edit your /etc/network/interfaces

auto wlan0
iface wlan0 inet dhcp
    wireless_essid ap_name
    pre-up wpa_supplicant -BW -Dwext -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf
    post-down killall -q wpa_supplicant


iface home inet dhcp
