I'm using Ubuntu 12.10 with Gnome 3.6 on a brand-new Samsung NP900X4C.
The installer detected the wireless adapter, took in the SSID and WPA passphrase, wrote these into /etc/network/interfaces and connected perfectly.
Once installation was finished I wanted to switch to using NetworkManager to manage the wireless adapter, since this is much more convenient than fiddling with /etc/network/interfaces every time I find a new hotspot.
Therefore I edited /etc/NetworkManager/NetworkManager.conf to set:
[ifupdown]
managed=true
When I rebooted NetworkManager, the problems started:
- The NetworkManager tray applet changed from saying device not managed to device not ready
- I lost all internet connectivity as wlan0 would not associate to the Access Point
- if I set managed=false in NetworkManager.conf and restarted both NetworkManager and networking services from the command-line, the Gnome desktop "semi-crashed" and lost all its Window Decorations, the panel, the launcher and basically became unusable.
However if I restart the computer completely after setting managed=false, wlan0 once again works perfectly.

Inmanaged=falsemode, wlan0 works after reboot because ifup configures it at boot time (if /e/n/i containsauto wlan0). Inmanaged=truemode, ifup doesn't bring interfaces up automatically; but then NetworkManager should do so. I don't know why it saiddevice not ready.

I ended up fixing this myself, see the exact steps below.
Note that there may be an easier solution but these steps definitely worked.
Make sure
network-manageris the latest version (I have 0.9.6.0-0ubuntu7 ).
You can check this with:sudo dpkg -l | grep network-managerRight-click on Network Manager tray icon -> Edit Connections -> Wireless -> Add
Manually add the parameters for connecting to your WLAN.Edit
/etc/NetworkManager/NetworkManager.confto set...[ifupdown]
managed=trueDO NOT restart
network-managerservice.Edit
/etc/network/interfacesto deactivate the auto-start of your Wireless interface (probably calledwlan0).
For example:From this:
auto wlan0
.... to this:#auto wlan0Run
/etc/init.d/network-manager force-reload
