I have installed Ubuntu 12.04. on my Dell Inspirion Mini 1018. After doing one of regular updates, my wifi stopped working, and it gives me message Wireless is disabled by hardware switch.

How can I enable it? I tried opening network connections, but there I find: Wireless Unavailable. Hardware Address 1C:65:9D:68:9E:6B

Then I tried System testing, it gives me a message:

# For some Atheros 5K RF MACs, the madwifi driver loads buts fails to
# correctly initialize the hardware, leaving it in a state from
# which ath5k cannot recover. To prevent this condition, stop
# madwifi from loading by default. Use Jockey to select one driver
# or the other. (Ubuntu: #315056, #323830)
  blacklist ath_pci"

This what I get after nm-tool :

Type: 802.11 WiFi
Driver: rtl8192ce
State: unavailable
Default: no
HW Address: 1C:65:9D:68:9E:6B

Wireless Properties

Next command I used sudo lshw -C network

As I am new on Ubuntu, I asked on Newbees forum, and here is what i did so far

One who was guiding me has no idea what to try next.

this is rough. In the thread they suggest to reset BIOS to default settings. Did you do that? If not, restart your computer and hold Ctrl-F11 immediately after startup. – phipsalabim Feb 21 '13 at 14:14

I'm not sure but I'm guessing this has nothing to do with Ubuntu: you have to press some keyboard key to activate the card (for example, Fn+F12 keys)
