Test Network Connection

Check if the wlan0 device exists:

ifconfig

Check if the wlan0 device is using the RTL8852BE chip driver:

readlink -f /sys/class/net/wlan0/device/driver

If the wlan0 device exists, it means the WiFi driver is loaded successfully. We proceed to connect to the WiFi network:

1. Open the /etc/wpa_supplicant.conf file and modify ssid and psk:

ssid is the WiFi name, and psk is the WiFi password.

For example:

ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
update_config=1

network={
        ssid="tspi-wifi-test_5G"
        psk="www.lckfb.com"
        key_mgmt=WPA-PSK
}

2. Create a /var/run/wpa_supplicant directory:

mkdir -p /var/run/wpa_supplicant

3. Kill any possibly running wpa_supplicant process:

killall wpa_supplicant

4. Use the wpa_supplicant command to connect to the WiFi network:

wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf

5. Obtain IP address (optional step, if IP address is not automatically obtained):

udhcpc -i wlan0

After successful connection, you can use the ping command to test if the network is connected:
