I have the BeagleBone Black Wireless, and I have flashed Ubuntu 16.04 to it. I am trying to make the WiFi to work but have so far failed. I have already tried to modify the /etc/network/interfaces file by adding the following commands for wlan0, without any luck:

auto wlan0
   iface wlan0 inet static
   address 192.168.1.2
   netmask 255.255.255.0
   gateway 192.168.1.1
   wireless-mode ad-hoc
   wireless-essid BBB

In some forums, people suggest using connmanctl, however, there is no such preinstalled package in Ubuntu. Also I can’t download it to the BBBw, because its WiFi is not working. I tried connecting the BBBw to the internet via a usb connection with a PC, I edited this connection to “shared to other computers” but again, I had no Internet connection to the BBBw.

To sum up, my question is: Is there an easy way to make the WiFi of the BBBw (with Ubuntu) to work, without the need to use the connmanctl?

If not, any detailed information on how to install the connmanctl would be very much appreciated.

I am including the whole /etc/network/interfaces file, with the part that I added, which appears after the comment “The following lines for the wlan0 were added by me”.

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp
# Example to keep MAC address between reboots
#hwaddress ether DE:AD:BE:EF:CA:FE

# The following lines for the wlan0 were added by me
# Ad-Hoc wifi
auto wlan0
   iface wlan0 inet static

#Using the appropriate ethernet service, tell connman to setup a static IP address for that service:
