无论是SD WiFi还是USB WiFi, 它们的连接方式都是一样的。正基科技的APXX系列芯片属于SD WiFi，另外系统默认也已经支持市面上众多常见的USB WiFi，已测试过的USB WiFi型号如下：

序号	型号
1	RTL8188CUS/8188EU 802.11n WLAN Adapter
2	RT2070 Wireless Adapter
3	RT2870/RT3070 Wireless Adapter
4	RTL8192CU Wireless Adapter
5	mi WiFi mt7601

You can use the NetworkManager utility in FriendlyCore to manage its network. You can run "nmcli" in the commandline utility to start it. Here are the commands to start a WiFi connection:

• Check device list

sudo nmcli dev

Note: if the status of a device is "unmanaged" it means that device cannot be accessed by NetworkManager. To make it accessed you need to clear the settings under "/etc/network/interfaces" and reboot your system.

• Start WiFi

sudo nmcli r wifi on

• Scan Surrounding WiFi Sources

sudo nmcli dev wifi

• Connect to a WiFi Source

sudo nmcli dev wifi connect "SSID" password "PASSWORD"

The "SSID" and "PASSWORD" need to be replaced with your actual SSID and password.If you have multiple WiFi devices you need to specify the one you want to connect to a WiFi source with iface
If a connection succeeds it will be automatically setup on next system reboot.

如果你的USB WiFi无法正常工作, 大概率是因为文件系统里缺少了对应的USB WiFi固件。对于Debian系统, 可以在/Debian-WiFi里找到并安装USB WiFi芯片的固件。而对于Ubuntu系统, 则可以通过下列命令安装所有的USB WiFi固件:

$ sudo apt-get install linux-firmware

一般情况下, WiFi的固件都存放在/lib/firmware目录下。
