Don't have my netbook (Dell Mini 9) in front of me right now but was working w/ it last night and I noticed I wasn't connecting to my home network via wireless. *knetworkmanager shows that networking has been disabled. Both wireless and wired does not work. *Tried to right click on knetworkmanager in the tray to select enable wireless but never saw any configuration options.

Any ideas?

I have the same problem, and yes, network-manager is running. At least, it's
running enough for me to be able to stop it and for iwconfig to not work til I
do so!

Me too, Here was the fix for me.

sudo service network-manager stop
cd /var/lib/NetworkManager/
sudo rm NetworkManager.state
sudo service network-manager start

Somehow
NetworkingEnabled=false
was false instead of true in there, yeah. I suspect on mine it's because I
hit the rfkill button. Rebooting should reset the rfkill button (it used to)
but it appears not to.

So after doing what you said I am left with KNM only offering "create new
wireless network" and not displaying available networks at all (no, the option
to choose a different network is not there).

Please file a regression-potential tagged bug against linux so that we
can fix it.

Sorry, bad phrasing. The wireless adapter itself goes back to working after
reboot, but because NetworkManager ignores that NM was disabled by the rfkill
being pressed and just assumes it's globally disabled, the result (to an end
user who doesn't know to use ifup) is like it stays disabled across reboots.

Are you by chance using the new network mangler thingy that Jonathan put in
a PPA? If so, do this:

qdbus org.kde.kded /kded org.kde.kded.loadModule networkmanagement

Nope, knetworkmanager. Just hit https://bugs.kde.org/show_bug.cgi?id=215080
too. (After like 4 reboots I convinced iwconfig that it was possible to
associate to an AP again, and eventually KNM after a few more.

Hm, you mean that network manager doesn't pick up you're wifi adapter being available
again? Can you reproduce the same with GNOME's nm-applet and maybe the Plasmoid? I've
been testing the hotplugging and rfkilling pretty extensively, and it works just fine
here.
