前幾天升級kernel 3.3

發現無線網路不能連@@

看了一下log之後發現

ADDRCONF(NETDEV_UP): wlan0: link is not ready

上網google了一下

終於找到解法了！

$ sudo pacman -S linux-headers  
$ wget http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2.6.tar.bz2  
$ tar -xv -f compat-wireless-2.6.tar.bz2  
$ cd compat-wireless-2012-04-09  
$ make  
$ sudo make install  
$ sudo make unload  
$ sudo sync; sudo reboot #重新開機這樣就OK了！
