A step-by-step guide on how to connect your Raspberry Pi 2 to a WiFi network using the command line interface.

To connect your Raspberry Pi 2 to a wireless network, you need to edit the configuration file of the operating system and restart the networking service. Follow these steps to set up a wireless connection:

  1. Open the terminal on your Raspberry Pi by clicking on the Terminal icon in the menu bar at the top left corner of the screen.

  2. Type the following command to open the WiFi configuration file in the nano text editor:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

  1. Press Ctrl + X to exit the nano editor and save your changes. If you haven’t made any changes yet, press Y to confirm saving the file and then hit Enter.

  2. Add the following lines to the end of the file:

network={
    ssid="your_wifi_network"
    psk="your_wifi_password"
}

Replace your_wifi_network with your WiFi network name and your_wifi_password with your WiFi password. Make sure to wrap the network name in double quotes if it contains spaces or special characters.

  1. Save the changes by pressing Ctrl + X, then Y, and finally Enter.

  2. Restart the networking service to apply the changes:

sudo systemctl restart dhcpcd
  1. Check if your Raspberry Pi is connected to the WiFi network by running the following command:
iwconfig

Look for the wlan0 interface and make sure it has an IP address assigned to it.

  1. If you want to test the connection, try pinging a website like Google:
ping google.com

If everything is set up correctly, you should see a series of responses from the server.

That’s it! You have successfully connected your Raspberry Pi 2 to a wireless network. Now you can use it without having to connect an Ethernet cable every time you want to access the internet.
