I registered on my Lubuntu 16.04.2 LTS Server via Wi-Fi, and every time I launch the docker container, my connection is deleted. Since I'm relatively new to docker, I can only guess that this is due to the creation of a virtual docker network. I should also mention that I disabled ipv6, but it does not make any difference if enabled.
Here is my syslog , it shows what happens when I run sudo docker run -it ubuntu bash. I see that the container / ubuntu asks for 2-3 seconds before it freezes. Doing it with help --net=hostworks, but that is not what I want.
ifconfig shows
