在一台老旧笔记本上安装了centos7
有一个usb 的无线网卡,tp-link TL-WN725N
芯片型号RTL8188EUS 802.11n Wireless Network Adapter
希望使用此网卡，因此需要安装驱动。
到芯片官网,中文官网没找到,搜索到英文官网的驱动,下载后却无法成功编译。
搜索到一个GitHub上的驱动 ,根据说明文档 成功编译安装。
驱动地址:/lwfinger/rtl8188eu
可能需要iwconfig 之类的工具,源码/HewlettPackard/wireless-tools
设置连接WiFi 直接看这个

后期发现使用 wpa_cli 管理WIFI(连接、切换等)更简单，因为：
wpa_supplicant
Thewpa_supplicantsystem consists of the following components:
wpa_supplicant.conf
the configuration file describing all networks that the user wants the computer to connect to.
wpa_supplicant
the program that directly interacts with the network interface.
wpa_cli
the client program that provides a high-level interface to the functionality of the daemon.
wpa_passphrase
a utility needed to constructwpa_supplicant.conffiles that include encrypted passwords.

man手册：/man/8/wpa_supplicant
注：此笔记本真的很旧，只能安装32位centos7.
