|'''When the development board is not connected to Ethernet, not connected to HDMI display, but only connected to the serial port, it is recommended to use the commands demonstrated in this section to connect to the WIFI network. Because nmtui can only display characters in some serial port software (such as minicom), and cannot display the graphical interface normally. Of course, if the development board is connected to an Ethernet or HDMI display, you can also use the commands demonstrated in this section to connect to the WIFI network.'''

1) First log in to the linux system, there are the following three ways<br>
a. If the development board is connected with a network cable, you can remotely log in to the Linux system through ssh<br>
b. If the development board is connected to the debugging serial port, you can use the serial port terminal to log in to the Linux system<br>
c. If the development board is connected to the HDMI display, you can log in to the linux system through the terminal displayed on the HDMI<br><br>
2) First use the '''nmcli dev wifi''' command to scan the surrounding WIFI hotspots<br>

|-
|orangepi@orangepi:~$ '''nmcli dev wifi'''
|}

3) Then use the nmcli command to connect to the scanned WIFI hotspot, where：<br>
a. '''wifi_name''' needs to be replaced with the name of the WIFI hotspot you want to connect to<br>
b. '''wifi_passwd''' needs to be replaced with the password of the WIFI hotspot you want to connect to<br>
