Wireless Network

Connect to a wireless router using the ROCK 4D's onboard WiFi. After a successful connection, the router will automatically assign an IP address to the ROCK 4D.

tip

The ROCK 4D has two onboard antenna connectors. You need to install the antennas in these positions; otherwise, the WiFi signal will be very poor.

Graphical Interface

① Click on the network icon

② Click the Connect button next to the WiFi network name you want to connect to

③ Enter the WiFi password and follow the prompts to complete the connection

After a successful connection, select the Details option to view detailed network connection information, such as IP address, subnet mask, gateway address, etc.

Command Line

1. Enable WiFi

radxa@radxa-4d$

sudo nmcli radio wifi on

2. Search for nearby WiFi networks

radxa@radxa-4d$

sudo nmcli device wifi list

3. Connect to a WiFi network

radxa@radxa-4d$

sudo nmcli device wifi connect <SSID> password <PASSWORD>
# Example
sudo nmcli device wifi connect wifi_demo password 12345678
