WIFI

EC-Orin NX supports wireless WIFI, and the default name of the network
card in the system is "wlanx" or "wlPxp1s0" (depending on different
wifi modules). Taking "wlan0" as an example:

   linaro@sophon:~# ifconfig wlan0
   wlan0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
           ether 20:57:9e:ba:02:fc  txqueuelen 1000  (Ethernet)
           RX packets 0  bytes 0 (0.0 B)
           RX errors 0  dropped 0  overruns 0  frame 0
           TX packets 0  bytes 0 (0.0 B)
           TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

WIFI Connection

(1) Enable WIFI:

   nmcli radio wifi on

(2) Check if WIFI is successfully enabled:

   # Printing out enabled indicates success
   nmcli radio wifi

(3) Check WIFI access points:

   nmcli dev wifi

(4) Connect to a WIFI access point:

Here, "zouxftest1" is the name of the WIFI access point, and
"12345678" is the password.

The successful connection log is as follows:

You can create a wireless AP hotspot using the "nmcli" command:

   sudo nmcli device wifi hotspot ifname wlan0 con-name my-hostapt ssid zouxftest7 band bg password 12345678 channel 5

con-name: Connection name, defined here as my-hostapt

ssid: Name of the created AP hotspot, defined here as zouxftest7

band: WIFI protocol standard, chosen here as bg
