How to configure a Wi-Fi Network?

Here's a step-by-step guide for setting up WLAN, i.e. on the RevPi Connect 4 module

Option 1: Using the Terminal (nmtui):

1. Open the terminal

2. Type sudo nmtui and press Enter.

3. In the menu, select "Activate a connection" and then choose your Wi-Fi network.

4. Enter the Wi-Fi password when prompted.

Option 2: Using Terminal (nmcli)

1. Open the terminal

2. Set Your Country:

   sudo raspi-config nonint do_wifi_country DE

   • This command sets the Wi-Fi regulatory domain to the specified country (in this case, Germany - DE). It's important to configure this setting to comply with local regulations.

3. Check Wi-Fi Radio Status:

   nmcli radio wifi

   • This command checks the status of the Wi-Fi radio. It will indicate whether the Wi-Fi radio is enabled or disabled.

4. Enable Wi-Fi Radio:

   sudo nmcli radio wifi on

   • If the Wi-Fi radio is not already enabled, this command turns it on.

5. List of Available Wi-Fi Networks:

   • This command lists the available Wi-Fi networks in the vicinity along with their signal strength, security type, and other relevant information.

6. Connect to Wi-Fi Network:

   • Replace "YourWiFiSSID" with the name (SSID) of your Wi-Fi network.

   • This command prompts you to enter the Wi-Fi password. Once entered, it establishes a connection to the specified Wi-Fi network.

7. Replace "YourWiFiSSID" with your Wi-Fi network name.

8. Enter the Wi-Fi password when prompted.

Option 3: Using the Graphical Desktop Interface:

1. Click on the Wi-Fi icon in the top-right corner of the desktop.

2. A list of available Wi-Fi networks will appear.

3. Click on your Wi-Fi network and enter the password when prompted.

These steps should help you connect your RevPi Connect 4 to your Wi-Fi network.
