My wife's nebook has Ubuntu 10.04.2 LTS (kernel 2.6.32-33-generic i686), and is using the linux driver for Realtek RTL819x wifi cards. I installed the driver ages ago with:
$ sudo add-apt-repository ppa:lexical/hwe-wireless
$ sudo apt-get update
$ sudo apt-get install rtl8192ce-dkms
and it has worked fine until an update 2 days ago.
Now "This driver is activated but not currently in use", and the wifi antenna LED is orange (I think it should be green to be on?) There is a hotkey combination ([Fn][F8]) to supposedly turn off and on the wireless antenna, but this has no effect. Also, the little network applet indicator isn't on her top panel anymore, so I can't right click it and enable wireless that way.
$ ifconfig

Normally that should list wlan0 for the wireless.

Grrr!
