This question already has an answer here:

I did a software update on my HP 250 G3, after that the icon of the network manager is gone, connection is gone, if I plug an Ethernet cable in, nothing happens. If I go to settings > network, a pop up shows up

Network services are not compatible with this version of the system

OS is Ubuntu 14.04.

Screen of lshw -class network

Any idea?
