For either an SD WiFi or a USB WiFi you can connect it to your board in the same way. The APXX series WiFi chips are SD WiFi chips. By default FriendlyElec's system supports most popular USB WiFi modules. Here is a list of the USB WiFi modules we tested:
Index Model 1 RTL8188CUS/8188EU 802.11n WLAN Adapter 2 RT2070 Wireless Adapter 3 RT2870/RT3070 Wireless Adapter 4 RTL8192CU Wireless Adapter 5 mi WiFi mt7601 6 5G USB WiFi RTL8821CU 7 5G USB WiFi RTL8812AU
You can use the NetworkManager utility to manage network. You can run "nmcli" in the commandline utility to start it. Here are the commands to start a WiFi connection:
- Change to root
$ su root
- Check device list
$ nmcli devNote: 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
$ nmcli r wifi on- Scan Surrounding WiFi Sources
$ nmcli dev wifi- Connect to a WiFi Source
$ nmcli dev wifi connect "SSID" password "PASSWORD" ifname wlan0
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.

If your USB WiFi module doesn't work most likely your system doesn't have its driver. For a Debian system you can get a driver from Debian-WiFi and install it on your system. For a Ubuntu system you can install a driver by running the following commands:
$ apt-get install linux-firmware
In general all WiFi drivers are located at the "/lib/firmware" directory.
