Wifi stops to work on Arch Linux

Today, my wifi stops work! Wicd is no longer detect any wifi network!

The first thing, i check ifconfig

?
Okay, no wireless card is up, check ifconfig -a

?
So, everything’s good!

I tried to make it up!

?
Shame on me, i even don’t know what RF-kill is!

Okay, i do a google and found rfkill! Install it

Then check :

?
i found that Hard blocked is when you turn off wifi button on laptop!

Soft blocked seems come from something like driver/module…I don’t know!

Any way, unblock it!

?
And now, wlan up just work fine

?
Next, i restart system! Ooops, it get soft blocked again after reboot!

So, i guess need some flag in booting process to let system know that don’t block it!

Google is friend, i found need to add

?
to /etc/modprobe.d/modprobe.conf

Okay, reboot, work!

WiCD can’t detect wireless network now!
