Debian系列Linux的WiFi配置

Debian系列Linux共用相同的deb安裝包，擁有大量的各類軟件，是Linux裏面最主要的生態系。包括Ubuntu及其衍生版本如Lubuntu/Mate/Kubuntu等，在ARM上也有恆好的支持如Rapsberry、LXDE、Hypriot等。

對於Linux服務器的版本如Hypriot，初始鏡像沒有鏈接無線網絡，怎麼安裝上網絡支持呢？

須要首先鏈接有線網，或者下載network-manager相應版本，而後運行dpkg -i 安裝上，而後就可使用nmcli的命令行進行網絡管理了。

sudo apt install network-manager

安裝完後，可使用下面的nmcli命令行或者nmtui進入交互界面進行管理。

Networks

#nmcli dev wifi list
SSID                              BSSID               MODE             FREQ       RATE       SIGNAL   SECURITY   ACTIVE

加入Wifi鏈接 SSID MYHOME ，在Fedora上：

nmcli con add con-name MyCafe ifname wlan0 type wifi ssid MyCafe ip4 192.168.100.101/24 gw4 192.168.100.1
