[Solved][Sumsung530U][wireless issue] wlan0 disappeared

Several hours ago, My laptop suddenly disconnected from the wifi. When I tried to connect again, I was surprised that my wlan0 disappeared from `iwconfig`. I wasn't updating the system at that time, and restarting the system doesn't work either. I found my wifi driver iwlwifi threw many errors in the log(errors.log):

Re: [Solved][Sumsung530U][wireless issue] wlan0 disappeared

Uuhhh.... what did you try?  What information have you already found?  Have you looked for information?

Rfkill?  Modules [re]load?  Pants?  Cheeseburgers?  7?

1. `rfkill list` shows nothing was blocked
2. I've tried to restart the computer and reload r8169 module. I also tried to rebuild the kernel image and reinstall some related packages( namely, wireless_tools, wpa_supplicant)
3. I'm sorry, but what do you mean by 'Pants'  'Cheeseburgers' or  '7' (I'm not native English speakers)

I downgrade the kernel from 3.6.11 to 3.6.9, and the problem was fixed
