Hi,

Do this

Code:
rfkill list
Hard blocked is when you turn off wifi button on laptop!
Soft blocked seems come from something like driver/module

Code:
rfkill unblock 0
Code:
rfkill unblock 1
Then try if it works:

Code:
sudo ifconfig  wlan0 up
Restart system, it get soft blocked again after reboot!

You need some flag in booting process to let system know that don’t block it,as given below:

vim /etc/modprobe.d/modprobe.conf

Quote:
options ath_pci rfkill=0

Same thing here with my Atheros. The hard block only occurs when suspending to disk (hibernation) and "rfkill unblock all" don't release it. It started with kernel 2.6.36. Suspending to ram goes without problem. I had two options to bring wireless up again: rebooting or removing the modules and blacklisting rfkill before probing ath5k again, but I loose acer_wmi functionality.

@BanSton,

I was wrong about the kernel. First time I saw this error was shortly after I had 2.6.36 compiled. Playing recently with ConsoleKit I lost permission to manage power functions when starting KDE by console. Sent the system a "few" times to memory/disk and all came clean. The bug goes away... Sorry for misleading.

No changes made. If you have udev 1.6.4, yesterday I saw this on changelog (Slackware):
Quote:
...
a/udev-164-x86_64-2.txz: Rebuilt.
Set rfkill device writable by netdev group.
...
That 'rfkill' got my attention...
