[root@www hybrid-wl]#
# modprobe lib80211 # 因为 wl.ko 需要依赖该模块
[root@www hybrid-wl]# modprobe lib80211
[root@www hybrid-wl]#
# insmod wl.ko
[root@www hybrid-wl]# insmod wl.ko
[root@www hybrid-wl]#
添加开机启动
# cp wl.ko /lib/modules/3.10.0-514.6.1.el7.x86_64/kernel/drivers/net/wireless （将wl.ko复制进去，其中3.10.0-514.6.1.el7.x86_64是你的内核版本，可以进入modules文件夹中ls一下）
# depmod -a
# echo modeprobe wl >> /etc/rc.local
重启后，看看系统能否自动加载模块
lsmod | grep

，此时我们只需要将wlp0s29u1u6激活;
借助wireless_tools和wpa_supplicant（因为现在的无线wifi网络大多是wpa加密。所以需要移植wpa_supplicant工具）等工具实现wifi的过程
