上面是我创建的群聊，欢迎新朋友的加入。

1.下载驱动源码

https://gitee.com/jun626/rtl8188eus.git

把源码拷贝到内核目录下

2.配置内核

在路径/linux-master/drivers/net/wireless下 gedit Kconfig 在最后添加 source

"drivers/net/wireless/rtl8188eus/Kconfig" gedit Makefile 添加 obj-y += rtl8188eus/

回到文件系统根目录

make linux-menuconfig Device Drivers ---> 
[*] USB support ---> 
<*> Support for Host-side USB 
<*> EHCI HCD (USB 2.0) support 
<*> OHCI HCD (USB 1.1) support 
<*> ChipIdea Highspeed Dual Role Controller 
[*] ChipIdea host controller 
[*] ChipIdea driver debug Device Drivers ---> 
[*] Network device support ---> 
[*] Wireless LAN ---> 
<*> IEEE 802.11 for Host AP (Prism2/2.5/3 and WEP/TKIP/CCMP) 
[*] Support downloading firmware images with Host AP driver 
[*] Support for non-volatile firmware download 
[*] Networking support ---> -*- Wireless ---> 
[*] cfg80211 wireless extensions compatibility 
<*> Generic IEEE 802.11 Networking Stack (mac80211)

3.文件系统

文件系统增加功能IW和WPA_SUPPLICANT

4.测试

ifconfig -a ifconfig wlan0 up iw wlan0 scan//查找WIFI

配置

cd ./etc vi wpa_supplicant.conf 内容为 
ctrl_interface=/var/run/wpa_supplicant 
update_config=1 
network={ 
    ssid="SSID" 
    psk="Password" 
} 

连接 
wpa_supplicant -D nl80211 -i wlan0 -c /etc/wpa_supplicant.conf
