ieee80211 phy0: Selected rate control algorithm 'rtl_rc' rtlwifi: rx_max_size 15360, rx_urb_num 8, in_ep 1 ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready I took me some time to find out I need a USB extension cable between the Beaglebone and the adapter but now the adapter powers up reliably and nothing hangs anymore. I use a Edimax nano USB adapter with a Realtek 8192 CU chipset - this is the same chipset like Adafruit sells: It seems it doesn't get an IP address - here are all the details: This will create the file /etc/wpa_supplicant/wpa_supplicant-wlan0.I can't get WiFi to work on my BeagleBone Rev A6a using the Angstrom 09-12-12 which shipped with it. Assuming your interface is named wlan0, run the following command, type your WPA or WPA2 password, and hit Enter: wpa_passphrase '*your_ssid_here*' > /etc/wpa_supplicant/wpa_nf In case you haven't configured WPA or WPA2 on your interface yet, we need to configure wpa_supplicant.

# NetworkManager users will probably want the dbus version instead.ĮxecStart=/usr/bin/wpa_supplicant -Dwext -c/etc/wpa_supplicant/wpa_supplicant-%I.conf file is very similar to but specifies the wext driver instead of defaulting to nl80211.

However, there is one downside: the 8192cu kernel module does not support the nl80211 driver, a modern method to connect to WPA and WPA2 networks and is the only 'stock' option when running systemd-networkd. If you are in the market for an inexpensive 802.11n solution for your Pi, Realtek 8192CU-based adapters are an excellent choice, and there are literally dozens to choose from and many of these great adapters are $5-10 dollars shipped on eBay.
