configure wifi

old

edit /etc/network/interfaces manually uncomment lines around wlan0 (or your identifier) adding SSID and passphrase

See the article Setting up WiFi with BeagleBone Black at Adafruit for copious details.

new - connmanctl

At least for me using the old method above was not available starting with debian jessie. You need to use connmanctl now. with the 8.4 and 8.5 images wifi tether is on by default. Turn it off to configure as follows. This will allow your BBB to obtain an ip address via DHCP from your Access point allowing you to ssh in.
