How To Setup WiFi on Raspberry Pi 3 – Here Are 5 Easy Methods

Method 1: Setting Up WiFi Using the Desktop GUI

The easiest way to configure WiFi on your Raspberry Pi 3 is using the graphical desktop interface. If you are running the standard Raspbian operating system, it comes with a desktop environment that provides a simple way to get connected. Here’s how to do it:

Boot up your Raspberry Pi 3 and wait for the desktop to load.
Look for the network icon in the top-right corner of the screen (it looks like two computers).
Click the icon to open the network menu. It will show a list of available WiFi networks.
Select your WiFi network from the list and click to connect.
Enter the password for the network when prompted.
Wait a few seconds and you should see a confirmation that you are now connected to the WiFi network.

That’s it! Your Raspberry Pi should now be online. You can open the Chromium web browser to test your connection by visiting a website.

If your WiFi network is hidden and not broadcasting its SSID publicly, you’ll need to click the “Other Network” option in the network menu and manually enter your network name and password to connect.

Method 2: Setting Up WiFi by Editing wpa_supplicant.conf

Another way to set up WiFi is by directly editing the wpa_supplicant.conf configuration file on your Pi. This file stores the WiFi networks that your Raspberry Pi 3 can connect to. Here are the steps:

Open a terminal window on your Pi. You can do this by clicking the terminal icon in the top menu bar or by pressing Ctrl+Alt+T on your keyboard.
In the terminal, type the following command and press Enter to open the wpa_supplicant.conf file in the nano text editor:
sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
In the nano editor, you will see the contents of the config file. Navigate to the bottom and add a new network block with your WiFi details like this:
network={ ssid="Your_Network_Name" psk="Your_Network_Password" }
Replace Your_Network_Name with the actual name of your wireless network, and Your_Network_Password with the password required to connect.
If your network is hidden, add the following line to the block as well:
scan_ssid=1
Press Ctrl+X, then Y, and finally Enter to save the changes to the file and exit nano.
Reboot your Raspberry Pi with the following terminal command:
sudo reboot

Once your Pi reboots, it should automatically connect to the configured WiFi network. You can verify by checking the network icon or pinging a website like google.com in the terminal.

Method 3: Setting Up WiFi Using the Command Line

You can also use command line tools like raspi-config to set up WiFi if you prefer working in the terminal. Here’s how:

Open a terminal window on your Raspberry Pi.
Run the following command to launch the raspi-config tool:
sudo raspi-config
Use the arrow keys to navigate to the “Network Options” item and press Enter.
Select “Wi-Fi” from the submenu and press Enter.
Choose your country from the list to set the correct wireless channels and press Enter.
Enter the name (SSID) of your WiFi network and press Enter.
Enter the password for the network and press Enter.
Review the settings and if they look correct, select “Finish” and press Enter.
Reboot your Pi when prompted to activate the WiFi configuration.

After rebooting, your Raspberry Pi 3 should be connected to the wireless network you configured. You can double-check by running the ifconfig wlan0 command and looking for an IP address, or by pinging a site like raspberrypi.org.

Method 4: Setting Up WiFi Headlessly (Without a Monitor)

What if you want to set up WiFi on your Raspberry Pi 3 but don’t have a spare monitor and keyboard? No problem – you can preconfigure the WiFi details on the SD card before booting up your Pi for the first time. This is handy for setting up a “headless” Pi that you’ll access remotely over the network. Here’s what to do:

Flash the Raspbian operating system image to your SD card using a tool like Etcher or the official Raspberry Pi Imager.
Once finished, do not eject the SD card from your computer just yet. Open the boot partition on the card – it will contain files like cmdline.txt and config.txt.
Create a new empty file in the boot partition called wpa_supplicant.conf. Make sure it has that exact name and extension.
Open the wpa_supplicant.conf file in a plaintext editor on your computer and paste in the following, replacing the placeholders with your actual network name and password:
“`
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US

network={
ssid=”Your_Network_Name”
psk=”Your_Network_Password”
key_mgmt=WPA-PSK
}
`` If you are in a country other than the US, change thecountry=line to your two-letter ISO country code. 5. Save thewpa_supplicant.conf` file and safely eject the SD card from your computer.
6. Insert the SD card into your Raspberry Pi 3 and power it on.

On first boot, your Pi will copy the wpa_supplicant.conf file to the proper location on the filesystem and connect to the specified wireless network automatically. You won’t even need to log in or attach a monitor!

You can then access your Pi over the network using SSH or VNC and start using it headlessly. Very handy for embedded projects or when deploying multiple Pis.

Method 5: Connecting to WiFi Using wicd-curses

One final method to set up and manage WiFi networks on the Raspberry Pi is using the wicd-curses utility in the terminal. It provides an easy pseudo-graphical interface for selecting and connecting to wireless networks. Here’s how to use it:

Open a terminal window on your Raspberry Pi and install the wicd-curses package with the following command:
sudo apt update && sudo apt install wicd wicd-curses -y
Launch wicd-curses with this command:
sudo wicd-curses
Press the right arrow key to move to the “Wireless Networks” tab. You will see a list of detected WiFi networks.
Use the up/down arrow keys to select the network you want to connect to and press the right arrow key.
If the network requires a password, enter it in the “Key” field.
Navigate to “” and press Enter to initiate the connection.
Once you see the status change to “Connected” in the bottom bar, your Pi is online! Press Q to quit out of wicd-curses.

The wicd-curses utility makes it easy to switch between wireless networks and manage connections in a terminal environment. It’s a handy tool to have if you frequently change networks or prefer working in the command line.

Troubleshooting Tips

If you encounter issues while trying to set up WiFi on your Raspberry Pi 3, here are a few troubleshooting tips that may help:

Make sure you are using the correct wireless network name (SSID) and password. Double-check for typos or case sensitivity.
If your WiFi network is hidden (not broadcasting SSID), make sure you have enabled the scan_ssid=1 option in the wpa_supplicant.conf file.
Check that your Pi is in range of the wireless router and there are no obstructions or interference.
Verify that your WiFi country code is set correctly in raspi-config or wpa_supplicant.conf, as this can affect available wireless channels.
Try rebooting your Raspberry Pi after making configuration changes to ensure they take effect.
If all else fails, you can try completely deleting the existing wpa_supplicant.conf file (after making a backup) and recreating it from scratch.
