NetEraser Review 2026: Features, Pricing, and Alternatives
Summary
- NetEraser is an open-source Wi‑Fi deauthentication tool (BW16 / RTL8720DN-based) designed to scan local 2.4GHz and 5GHz networks and send deauth frames to disconnect target APs and clients. It’s distributed as Arduino-compatible firmware with a simple web UI served from the device.
Key features
- Hardware-focused: built for Ai‑Thinker BW16 (RTL8720DN) development boards.
- Dual‑band support: deauthenticates both 2.4GHz and 5GHz networks.
- Local web interface: device creates an AP named “NetEraser” (password: neteraser) and serves a selection UI at 192.168.4.1.
- Minimal setup: Arduino IDE build and upload, board auto‑flash mode supported.
- Visual indicators: LED states for ready (green) and active deauth (red).
- GPL‑3.0 license and community source on GitHub.
How it works (technical overview)
- Flash NetEraser.ino to the BW16 board.
- Device boots as an access point; connect and open the web UI.
- Scan for nearby SSIDs, pick a target, click Start — the board sends IEEE 802.11 deauthentication frames to clients/APs.
- Stops when you click stop or on user intervention.
Pros
- Simple, self-hosted tool for local network testing and experimentation.
- Low-cost hardware requirement.
- Open-source: inspect, modify, and extend.
- Supports both common Wi‑Fi bands.
Cons and legal/ethical note
- Deauthentication attacks disrupt networks and connected users. In many jurisdictions using such a tool against networks you do not own or manage is illegal and unethical. Use only on networks you own or have explicit permission to test.
- No official releases; community repo with modest maintenance and limited support.
- Limited features compared with professional wireless‑testing toolkits (no advanced client tracking, capture, or reporting).
- Hardware-specific — not plug‑and‑play on other boards without porting.
Pricing
- NetEraser itself is free (open-source). Costs you’ll incur:
- BW16 (RTL8720DN) dev board: typically low-cost (~\(8–\)30 depending on supplier and region).
- Development environment: free (Arduino IDE).
- Optional: enclosures, power supplies, or multiple boards for broader testing.
Practical use cases
- Authorized wireless penetration testing and red‑team exercises (with permission).
- Educational demonstrations of Wi‑Fi management frame vulnerabilities.
- Hardware hobbyist experimentation and firmware development.
Alternatives
- Open-source / low-cost hardware tools:
- ESP8266/ESP32 deauth scripts (many community projects) — similar capability on cheaper boards but may be limited to 2.4GHz (ESP32 variants can vary).
- WiFi Pineapple (Hak5) — commercialized platform with broad testing features, UI, plugins; higher cost but full feature set for professionals.
- Bettercap (with compatible Wi‑Fi adapters) — advanced MITM and Wi‑Fi testing toolkit for Linux with richer feature set.
- Professional / commercial wireless test suites:
- Aircrack-ng suite + compatible adapters — packet capture, injection, cracking, and analysis for security testing.
- Ekahau / AirMagnet (enterprise tools) — professional Wi‑Fi planning and security assessment (expensive, enterprise oriented).
Verdict
- For hobbyists and developers who need an inexpensive, self‑hosted deauth tool on RTL8720DN/BW16 hardware, NetEraser is a practical, open‑source option. It’s not a substitute for professional wireless‑testing platforms if you need robust features, reporting, or commercial support. Crucially, only use NetEraser on networks where you have explicit authorization to test.
