Comment # 8 on bug 819514 from a b

I have installed a laptop today with
 cat /etc/SuSE-release 
openSUSE 42.1 (x86_64)
VERSION = 42.1
CODENAME = Malachite

all latest patches installed.

the networkmanger is still behaving strange. the symptom was that the NM
insisted of starting dhcpc even when not needed.

After a lot of seraching i found:
/etc/NetworkManager/system-connections/<connectionname>

in <connectionname> I changed 
autoconnect=false -> autoconnect=true

i have no clue how to set autoconnect from nmtui or so
