How to get my disappeared network connection to work again?

Question

I am using Ubuntu 14.04 LTS on a laptop. Suddenly my Network possibilities have disappeared. (No network connection and no show of the network icons or in control panel) The laptop has a fixed ethernet connection and a working wifi (802.11g).

So far I have tried several things, but can not get it working.

Any suggestions?

@Andriod Dev : here are the lsusb and lspcihow can I put them in? I cannot attatch png here, or how can I copy from the terminal, I haven't figured this out yet... — FlyingDutchMan, May 16 '16 at 15:45
Just click and drag in the terminal, and then copy & paste it in your answer. — You'reAGitForNotUsingGit, May 16 '16 at 16:16

these are the needed ones, I guess. The file is a little too big for the comment field — FlyingDutchMan, May 16 '16 at 16:26
I believe the problem is exactly what @Albert described, however, I wasn't lucky in executing the solution — FlyingDutchMan, May 16 '16 at 16:27

I found an old thread:

Last upgrade crashes network manager (no internet connection, no applet)

After downgrading libnl I could restart the network manager.

Later, Ubuntu obviously suggested upgrading again libnl but also other packages. I did it and everything works.

Thanks, I have found this thread myself and tried, it did not work as expected. Maybe because, I am a novice user or maybe it didn't work. In any case, unfortunately, I still have the problem – FlyingDutchMan May 16 '16 at 15:50
