Setup Instructions

1. Clone Repository and Flash the Code

1. Clone this repository to your local machine:

   git clone https://github.com/your-repo-name/esp8266-wifi-jammer.git
   cd esp8266-wifi-jammer

Flashing the Code to Node MCU

1. Open the Code

• Open the provided Wi-Fi jamming code in Arduino IDE.

2. Customize the Code

• Modify the parameters as needed:
  • CHANNEL: Set the Wi-Fi channel to target (1–14).
  • JAMMING_DURATION: Specify the duration of jamming in seconds.

3. Configure Arduino IDE

• In Arduino IDE, go to Tools and select:
  • Board: NodeMCU 1.0 (ESP-12E Module)
  • Port: Select the COM port where the Node MCU is connected.

4. Upload the Code

• Click Upload to flash the code to the Node MCU.

Execution

1. Run the Program

• Power the Node MCU, and it will start emitting jamming signals to disrupt nearby Wi-Fi networks.

2. Observe the Effects

• Devices within range will experience connectivity issues:
  • Smartphones: Loss of Wi-Fi, slow speeds, or dropped calls.
  • Laptops/PCs: Interrupted internet access or connectivity.
  • IoT Devices: Loss of communication and functionality.

Observing Effects

Device	Effect
Smartphones	Dropped Wi-Fi, slow speeds, lost calls
Laptops/PCs	Interrupted connectivity, internet disconnections
IoT Devices	Loss of functionality, inability to connect

---

Mitigation Techniques

• Strong Signal: Use high-gain antennas and position routers strategically.
• Frequency Hopping: Deploy networks using FHSS (Frequency Hopping Spread Spectrum) technology.
• Enhanced Security: Use robust encryption (e.g., WPA3) and strong passwords.

Ethical Considerations

⚠️ Important

• Unauthorized Wi-Fi jamming is illegal and can lead to severe consequences.
• Perform this project only in controlled environments with proper permissions.
• Avoid disrupting public or critical services.
