Download the most powerful WiFi jammer 2026 – Disrupt any 2.4GHz or 5GHz network. Deauth attacks, beacon flooding, probe requests. For security research only.
This is a professional-grade WiFi deauthentication tool that can disrupt wireless networks within range. It sends deauth packets to force devices offline – useful for authorized security testing and network troubleshooting.
What this tool can do:
- ✅ Disconnect all devices from a target network
- ✅ Disconnect a single device (by MAC address)
- ✅ Flood networks with beacon frames (cloaking)
- ✅ Probe request flooding (overwhelm access points)
- ✅ Works on 2.4GHz and 5GHz bands
- ✅ Supports WPA/WPA2/WPA3 networks
| Feature | What It Does |
|---|---|
| 📡 Deauth Attack | Send 802.11 deauthentication frames – kicks devices off WiFi |
| 🎯 Targeted Attack | Kick a single device by MAC address (ignore others) |
| 🔍 Network Scanner | Detect all nearby access points and connected clients |
| 📊 Packet Injection | Raw packet injection – bypasses normal WiFi security |
| 🌐 Dual Band | Works on 2.4GHz (channels 1-11) and 5GHz (channels 36-165) |
| 🚫 Beacon Flood | Spoof hundreds of fake access points (SSIDs) |
| 🔄 Probe Flood | Overwhelm APs with probe requests – causes slowdowns |
| 📝 Packet Capture | Save captured handshakes for offline analysis |
- Security professionals testing their own network resilience
- Penetration testers performing authorized audits
- Network administrators troubleshooting WiFi interference
- Students learning wireless security (ethical hacking courses)
- Parents who want to disconnect kids' devices temporarily (with permission)
⚠️ EDUCATIONAL & AUTHORIZED USE ONLY. Using this on networks you don't own is illegal (Computer Fraud & Abuse Act).

📦 Size: ~45 MB (includes drivers and dependencies)
You need a WiFi adapter that supports packet injection. Built-in laptop cards usually DON'T work.
Compatible adapters (tested):
- Alfa AWUS036ACH (best, $40 on Amazon)
- Alfa AWUS036AC
- Panda PAU06 (budget option)
- TP-Link TL-WN722N (v1, not v2/v3)
- Windows: Run
Install_Drivers.bat(installs driver for your adapter) - Linux: No driver needed – pre-installed
- macOS: Limited compatibility – use Linux or Windows
Some AV flags packet injection tools – false positive.
The tool uses raw socket access, which antivirus may flag. It's 100% safe – only sends network packets.
📌 Why is this safe despite antivirus warnings?
The tool uses sendto() and pcap libraries – standard networking APIs. It does NOT:
- ❌ Install malware or keyloggers
- ❌ Access your files or passwords
- ❌ Send data to external servers
- ❌ Modify system files
All packet injection is local – you choose the target.
- Windows: Right-click
WiFi_Jammer.exe→ Run as administrator - Linux:
sudo python3 jammer.py
- Click "Scan Networks" – shows all nearby SSIDs
- Select target network
- Optional: Click "Scan Clients" – shows connected devices
- Choose attack mode:
- Deauth All – kick every device off the network
- Deauth Single – kick specific device (by MAC)
🔍 How does deauth attack work technically?
WiFi uses management frames to control connections. The deauthentication frame (802.11 type 0x0C) tells a device to disconnect.
These frames are unencrypted – even on WPA3 networks. The jammer spoofs the access point's MAC address and sends deauth packets to clients. Clients obey instantly, reconnecting a moment later (unless deauths are continuous).
Result: The device loses connection repeatedly – unusable until the attack stops.
| Feature | This Jammer | Windows netsh / iwconfig |
|---|---|---|
| Deauth attack | ✅ Yes | ❌ No |
| Single device targeting | ✅ Yes | ❌ No |
| Beacon flood | ✅ Yes | ❌ No |
| Packet capture | ✅ Yes | ❌ No (requires Wireshark) |
| 5GHz support | ✅ Yes (with compatible adapter) | ✅ Yes (scan only) |
| Ease of use | ✅ GUI + CLI | ❌ Command line only |
❓ Is this illegal to use?
Yes, unless you own the network. Using a jammer on networks you don't own violates the Computer Fraud and Abuse Act (CFAA) in the US and similar laws worldwide.
Legal uses:
- Testing your own home/business network
- Authorized penetration testing (with written permission)
- Academic research in controlled lab environments
- Parents on their own home network (their own devices)
Illegal uses: Hotels, cafes, schools, neighbors' WiFi, public hotspots – punishable by fines and jail time.
🖥️ Why isn't my built-in WiFi card working?
Most laptop WiFi cards (Intel, Realtek, Qualcomm) block raw packet injection in their drivers. You need an external USB adapter with open-source drivers.
Why? Chipset manufacturers don't want users sending deauth packets. Alfa and Panda adapters use chipsets that allow injection.
🔧 The jammer detects networks but can't deauth
Try these fixes:
- Confirm your adapter supports injection (check list above)
- Run as administrator (Windows) or sudo (Linux)
- Disable Windows Defender real-time protection
- Try a different USB port (USB 3.0 if possible)
- Change channel – some APs monitor for deauths
📡 Does this work on 5GHz networks?
Yes – with a 5GHz-capable adapter (Alfa AWUS036ACH, AWUS036AC). 5GHz channels (36-165) are supported. However, some 5GHz networks use 802.11ac/ax beamforming that reduces injection success.
🛡️ Can WPA3 networks be jammed?
Yes. Deauth frames are still unencrypted in WPA3. The attack works identically to WPA2. Management frame protection (MFP/802.11w) – rare in consumer routers – blocks deauth attacks.
🔄 How to stop the jammer once started?
Press Ctrl+C in the terminal window (CLI version) or click "Stop Attack" (GUI version). The tool stops sending packets immediately. Devices will reconnect within 5-10 seconds.
| Component | Requirement |
|---|---|
| OS | Windows 10/11, Ubuntu/Debian/Kali Linux, macOS (limited) |
| WiFi Adapter | External with injection support (Alfa, Panda, TP-Link WN722N v1) |
| RAM | 2 GB |
| Storage | 100 MB |
| Admin rights | Required for packet injection |
