On beaglebone black, I’m using Ubuntu 14.04 prebuilt image.
I have a problem.
I tried to connect with wifi.
I edited /etc/network/interfaces.
iface lo inet loopback
iface eth0 inet dhcp
iface eth0 inet static
iface wlan0 inet static
in the state that does not connect the eht0,
If eth0 is dhcp , wlan0 can connect.
If eth0 is staic , wlan0 not be able to connect.
What is solution?
Ubuntu I believe uses a different network manager. connman or some such program. I could not say which for sure as I have not used Ubuntu for a very long time. However, you should be able to use google.
try googling -----> Ubuntu 14.04 how to static ip
errrr . . . its before my morning “coffee”. But problem may still be google-able, and may very well still have to do with the network manager.
Thank you for your suggestion
Also, I’m sorry reply late.
So I am not native English, I takes time to write.
Ubuntu I believe uses a different network manager
I am aware network maneger is used in GUI environment, and, should not be used on the server without a GUI
Am I wrong?
Try change auto wlan0 to allow-hotplug wlan0.
After that, I started wlan0
Message is displayed
