Description:
Update of network manager from version 0.9.2.0-3 to 0.9.4.0-2 causes Realtek RTL8188CUS 802.11n WLAN usb to be seen as not ready.

This cannot be started at all, rebuilding drivers does not work.

Downgrading to version 0.9.2.0-3 allowed this to work again.

Additional info:
Networkmanager 0.9.2.0-3 to 0.9.4.0-2

I have a similar problem with a RTL8189SU USB adapter.
It seems that NetworkManager-0.9.4 sees this adapter as a wired adapter instead of a wireless adapter as shown in the log below:

Apr 23 19:12:57 tao NetworkManager[898]: <info> (wlan0): driver 'r8712u' does not support carrier detection.
Apr 23 19:12:57 tao NetworkManager[898]: <info> (wlan0): new Ethernet device (driver: 'r8712u' ifindex: 3)
Apr 23 19:12:57 tao NetworkManager[898]: <info> (wlan0): exported as /org/freedesktop/NetworkManager/Devices/0
Apr 23 19:12:57 tao NetworkManager[898]: <info> (wlan0): now managed
Apr 23 19:12:57 tao NetworkManager[898]: <info> (wlan0): device state change: unmanaged -> unavailable (reason 'managed') [10 20 2]
Apr 23 19:12:57 tao NetworkManager[898]: <info> (wlan0): bringing up device.
Apr 23 19:12:58 tao NetworkManager[898]: <warn> (wlan0): couldn't get carrier state: (-1) unknown
Apr 23 19:12:58 tao NetworkManager[898]: <info> (wlan0): carrier now OFF (device state 20, deferring action for 4 seconds)
Apr 23 19:12:58 tao NetworkManager[898]: <info> (wlan0): preparing device.
Apr 23 19:12:58 tao NetworkManager[898]: <info> (wlan0): deactivating device (reason 'managed') [2]
Apr 23 19:12:58 tao NetworkManager[898]: <info> Added default wired connection 'Wired connection 1' for /sys/devices/pci0000:00/0000:00:1c.5/0000:06:00.0/usb5/5-2/5-2:1.0/net/wlan0

Downgrading to 0.9.2.0-3 solved the problem.

I just installed the latest version of networkmanager (0.9.4.0-4) which doesn't disable WEXT and everything is working now :-)

My pacman saying that the latest version is 0.9.4.0-3. Will test once I can get 0.9.4.0-4

0.9.4.0-4 seems to have resolved this. :)
