Wi-Fi Configuration

If you want to configure Wi-Fi on a Raspberry Pi without a monitor (headless setup), you can do this via SSH whether by using a text based UI or issuing commands.

Here’s how you can configure your Wi-Fi:

1. SSH into the Raspberry Pi. The credentials are: root / replayos.
2. Use nmtui or nmcli to Configure your Wi-Fi.

Wi-Fi Configuration Using nmcli

To create a persistent Wi-Fi configuration file that NetworkManager will use on boot, you can use nmcli to add and modify a connection:

# Add Wi-Fi connection
nmcli connection add type wifi ifname wlan0 con-name "MyWiFi" ssid "YourSSID"

# Configure Wi-Fi security
nmcli connection modify "MyWiFi" wifi-sec.key-mgmt wpa-psk
nmcli connection modify "MyWiFi" wifi-sec.psk "YourPassword"

# Bring up the connection
nmcli connection up "MyWiFi"

Wi-Fi Configuration Using nmtui

Summary of Steps

1. Open nmtui: nmtui
2. Navigate to "Activate a connection": Use arrow keys and Enter
3. Select Wi-Fi Network: Choose your Wi-Fi network
4. Enter Wi-Fi Password: Enter the password for the network
5. Activate Connection: Wait for the confirmation of connection
6. Exit nmtui: Navigate to "Quit" and press Enter
