sudo sh -c 'wpa_passphrase WiFiSSID WiFiPassword >> /etc/wpa_supplicant/wpa_supplicant.conf'

That will add a new network to the bottom of your supplicant file from the command line.

To configure a Raspberry Pi OS system to connect to a Wi-Fi network and enable SSH access, you can either use the Raspi-config tool or modify the wpa_supplicant.conf file directly. Alternatively, the Raspberry Pi Imager tool can be used to configure both SSH and Wi-Fi during the initial image writing process. 

Using Raspi-config:

  1. Access Raspi-config: Open the Raspberry Pi configuration tool, either through the GUI (Preferences > Raspberry Pi Configuration) or by using the command sudo raspi-config.
  2. Navigate to Network Options: Select “Network Options” and then “Wi-Fi”.
  3. Configure Wi-Fi: Enter your network’s SSID and password.
  4. Enable SSH: In Raspi-config, under “Interface Options,” enable SSH to allow remote access.
  5. Reboot: After making changes, reboot the Raspberry Pi for the new settings to take effect. 

Modifying wpa_supplicant.conf:

  1. 1. Connect via Ethernet or SSH: If you have a wired connection, connect via Ethernet. Otherwise, connect via SSH to the Raspberry Pi after enabling SSH. 

2. Edit the file:

Use a text editor (like nano) to edit the wpa_supplicant.conf file: sudo nano /etc/wpa_supplicant/wpa_supplicant.conf. 

3. Add Wi-Fi network:

Add a new network entry with your SSID and password. Example: network={ scan_ssid=1 ssid="YourSSID" psk="YourPassword"}. 

4. Save and restart:

Save the changes and restart the networking service with sudo service networking restart. 

Using Raspberry Pi Imager:

  1. Enable SSH: In Raspberry Pi Imager, navigate to “Advanced Options” and enable SSH.
  2. Configure Wi-Fi: Select “Configure wireless LAN” and enter your Wi-Fi details.
  3. Write Image: Write the image to your SD card. 

Troubleshooting:

  • Incorrect password: Double-check your Wi-Fi password for any typos. 

Network issues: Ensure your router is configured correctly and accessible. Reboot: After making changes, always reboot the Raspberry Pi for the new settings to take effect. 

Additional Tips:

  • Find the IP address: If you’re connecting via SSH, you’ll need the Raspberry Pi’s IP address. You can find this by browsing your router’s settings or using a command like ip addr show eth0 (if using Ethernet) or ip addr show wlan0 (if using Wi-Fi) to display the IP addresses. 

Default username and password:

The default username for the Raspberry Pi is “pi” and the default password is “raspberry.” It’s highly recommended to change these for security reasons. 

Headless setup:

If you’re setting up the Raspberry Pi headless (without a monitor), you’ll need to use the methods involving the wpa_supplicant.conf file or using Raspberry Pi Imager to enable SSH and Wi-Fi before the first boot.
