After updating the OS today and rebooting, the wifi and ethernet has stopped working. Opening Network in the control panel gives me the error "The system network services are not compatible with this version".
What can I do to fix this?

I have the same problem. The above sollution seemed to get the icon back in the top right of screen, but nothing works in it– SpankalishCommented Jan 30, 2016 at 14:34

@Spankalish Maybe try rebooting, mine brought all the connection profiles right back though.– Lewis Goddard ♦Commented Jan 30, 2016 at 16:08

The Ubuntu proposed repository recently released version 3.2.21-1ubuntu1 of several libnl* packages. There currently break the networking manager in elementary OS Freya.
Step 1. Download the architecture appropriate files for these three packages.
Step 2. Downgrade the Packages and Restart the Service
sudo dpkg -i libnl-*.deb;
sudo service network-manager restart
Step 3. Make sure it doesn't happen again.
Uncheck the proposed repository from your update settings. Sometimes these checkboxes don't work, since it is older Ubuntu software, so comment out the lines in /etc/apt/sources.list

@Gabriel Any that contain the word "proposed", probably towards the end.– Lewis Goddard ♦Commented May 14, 2016 at 18:00
