To connect a Raspberry Pi to a Wi-Fi network using the WID340, follow the steps below.

1. Plug in the WID340: Plug the WID340 into an available port on the Raspberry Pi. If not enough ports are available, a USB hub can be used.
2. Edit the Wi-Fi settings: Open a terminal and run the command: sudo nano /etc/wpa_supplicant/wpa_supplicant.conf You can substitute "leafpad" for "nano" if you prefer a graphical text editor on most Raspberry Pi installations.
3. Add your Network: In the wpa_supplicant.conf file, add the following text: network={
    ssid=""
    psk=""
} Replace with the name of your Wi-Fi network, and with the password for your network. When you're finished, save the file and exit the text editor.
4. (optional) Restart the connection: The new information should be detected automatically, but if not, you can restart the WLAN0 interface to reload the wpa_supplicant.conf file using the command below: sudo ifdown wlan0
sudo ifup wlan0
