The Raspberry Pi 5 includes an onboard WiFi module, but for better performance, you might prefer to use a USB WiFi adapter. Whether you’re aiming for greater range, enhanced bandwidth, or specific network compatibility, this guide will show you how to disable the onboard WiFi and configure a USB WiFi adapter on your Raspberry Pi 5.

Why Use a USB WiFi Adapter on Raspberry Pi 5?

While the onboard WiFi is convenient, there are several reasons you might opt for a USB WiFi adapter:

• Improved signal strength: Some USB adapters come with external antennas that provide better range and signal quality.
• Faster connection speeds: Certain USB adapters support faster wireless standards, like WiFi 6.
• Special features: Advanced adapters may support extra features such as dual-band operation or enhanced security protocols.

Step-by-Step Guide to Disable Onboard WiFi and Set Up USB WiFi

1. Disable Onboard WiFi on Raspberry Pi 5

To force the Raspberry Pi 5 to use a USB WiFi adapter, you’ll first need to disable the onboard WiFi.

• Open the boot configuration file:

  sudo nano /boot/firmware/config.txt

• Add the following line to disable the onboard WiFi:

  dtoverlay=disable-wifi

• Save and exit the file, then reboot the Raspberry Pi:

  sudo reboot

2. Check If Onboard WiFi is Disabled

After rebooting, use iwconfig to confirm that the onboard WiFi is disabled:

  iwconfig

If done correctly, the onboard WiFi interface will not appear in the output.

3. Install USB WiFi Drivers (If Necessary)

After connecting your USB WiFi adapter, you may need to install drivers, though many adapters work without additional steps. To check if your adapter is recognized, run:

  lsusb

If your adapter is listed, you’re ready to proceed. Otherwise, search for drivers on the adapter manufacturer’s website or Raspberry Pi forums.

4. Configure the USB WiFi Adapter

To connect the Raspberry Pi to your wireless network using the USB WiFi adapter, configure the wpa_supplicant.conf file:

• Open the WiFi configuration file:

  sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

• Add your network details:

  network={
      ssid="Your_SSID"
      psk="Your_WiFi_Password"
  }

• Save the file and restart the WiFi service:

  sudo systemctl restart wpa_supplicant

5. Final Reboot

Reboot your Raspberry Pi once more to ensure all changes are applied:

  sudo reboot

Now, your Raspberry Pi 5 will use the USB WiFi adapter instead of the onboard WiFi.

Conclusion

Disabling the onboard WiFi on a Raspberry Pi 5 and switching to a USB WiFi adapter is a simple process that can significantly boost your Pi’s network performance. Whether you’re looking for faster speeds, improved range, or specific wireless features, a USB adapter offers a flexible solution. By following this guide, you’ll have your Raspberry Pi 5 optimized for wireless connectivity in no time.
