Complete step-by-step guide to getting WiFi running for your BeagleBone Black
UWN100 / UWN200
Tested with Debian image: BBB-eMMC-flasher-debian-7.4-2014-03-04-2gb.img Perform steps 1 and 2 without plugging in the WiFi device. All steps are performed as root user:
1. Create file /etc/wpa_supplicant/wpa_supplicant.conf
Change my_ssid to be the SSID name, and my_psk to be the alphanumeric text key (not hexadecimal) of up to 63 characters.
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid="my-ssid"
scan_ssid=1
psk="my-psk"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
auth_alg=OPEN
}
2. Modify /etc/network/interfaces file
Place these four lines at the top of the file:
allow-hotplug ra0
iface ra0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
3. Final steps
Plug in the USB WiFi adapter, and then type: ifup ra0 Then, power down safely (e.g. press switch S3 on the BBB), unplug the Ethernet cable and power back up. Log on to your router and check what IP address has been assigned to your BBB. You're done.
