Connman is annoying

Connman is the new way of doing networking apparently but why fix what isn't broken. I know the talk about 'what if the network falls' blah blah blah but if the network should fail then I'm up the Swanny anyway. A big minus side to connman is it doesn't work well with my wireless network. I don't need wireless really but I would like to make the whole hub fairly portable (just need mains supply) rather than need a network cable.

I don't want connman anywhere near my beaglebone.

I want this → http://www.unix.com/man-page/Linux/5/interfaces/

How to remove connman and revert to traditional network interface start up.

DISABLE CONNMAN
systemctl disable connman.service
