1. Extract the driver package to a directory, such as the newly created directory wlan.
2,
# Make clean
# Make
After compilation, the wl. ko file will be generated.
3,
# Make API = WEXT
4
,
# Rmmod b43
 
# Rmmod ssb
 
# Rmmod bcma
 
# Rmmod wl
Skip this step if the system prompts no installation.

Add b43 \ ssb \ bcma and other drivers to the blacklist so that they cannot be loaded later.
# Ech "blacklist ssb">/etc/modprobe. d/blacklist. conf
 
 
# Ech "blacklist bcma">/etc/modprobe. d/blacklist. conf
 
 
# Ech "blacklist b43">/etc/modprobe. d/blacklist. conf

,
# Modprobe lib80211
Or
# Modprobe ieee80211_crypt_tkip
 
# Insmod wl. ko
7
,
# Cp wl. ko/lib/modules/'uname-R'/kerneldrivers/net/wireless
 
Note that the point in 'uname-R' is the key under the ESC key, and 'uname-R' is to get the kernel version. Of course, you can directly write the kernel version number here.
# Depmod-
 
# Echo modeprobe wl>/etc/rc. local
By now, the driver and configuration of the wireless network card have been completed, and the wireless network card is working properly.
