I have the same problems that several people had before. Wifi ain't working.
However, installing the libnl-3-200 libnl-route-3-200 and libnl-genl-3-200 did not work, nor did downgrading.
At first it worked, however, after a reboot it stopped working again (not after the one immediately after the reinstallation but after the weekend ...) So I tried to fix it again, downgrading etc. Installing the libnl-* files did neither work using apt-get nor work by doing so manually. After hours of doing so I got frustrated and reinstalled elementaryOS for the first time. Again non aforementioned ways of fixing WiFi worked... after another hour of trying all fixes I could think of I'm now in the process of reinstalling it again (first time with active Ethernet ... )
Can anyone point out another way of fixing the WiFi
If you need any information to help me, please say so and I will do my best to deliver that info.
