wifi-deauth-test

A small Tkinter GUI that walks you through deauthenticating one client from a Wi-Fi network you own or are explicitly authorized to test. It is a guided front-end for the aircrack-ng suite (airmon-ng, airodump-ng, aireplay-ng).

If you just want the result and not the click-flow, wifite2 and airgeddon already do all of this.

⚠️ Responsible use

Sending 802.11 deauthentication frames to a network or client you do not own, or do not have written permission to test, is illegal in most jurisdictions (e.g. the US Computer Fraud and Abuse Act, the UK Computer Misuse Act).

This tool exists to test the resilience of your own network, for lab exercises, and for learning how the attack works. It targets a single client at a time. You are responsible for how you use it.

What it does

A step-by-step wizard:

Step	Screen	Under the hood
1	Select Wi-Fi card — lists wireless interfaces, flags which support monitor mode	iw dev, iw <phy> info
2	Monitor mode (on confirm) — saves current card state first	airmon-ng check kill, then airmon-ng start <iface>
3	Scan networks — 10 s scan, then a table of ESSID / BSSID / channel / signal / encryption	airodump-ng → CSV
4	Scan clients — 15 s scan locked to the chosen BSSID + channel, lists associated client MACs	airodump-ng --bssid <b> -c <ch> → CSV
5	Deauth — 30 s with a live countdown (auto-stops) or infinite (until you click Stop deauth)	aireplay-ng --deauth 0 -a <bssid> -c <client> <mon>
6	Stop & Reset card — always visible, any screen	see below

Reset behaviour

Before it touches the card, the tool records:

• the interface name and MAC address
• whether NetworkManager was running

Stop & Reset card (and closing the window) then:

1. kills any running airodump-ng / aireplay-ng
2. airmon-ng stop <mon>
3. renames / sets the interface back to managed if needed
4. restores the original MAC if it changed
5. systemctl start NetworkManager

The card ends up exactly as it was before step 2.

Requirements

• Linux
• root (sudo)
• aircrack-ng, iw, iproute2, python3-tk

sudo apt install aircrack-ng iw iproute2 python3-tk

• A Wi-Fi adapter whose driver supports monitor mode + packet injection. Many built-in Intel cards inject poorly; ath9k_htc (Atheros) and RTL8812AU adapters are the common choices.

---

Usage

sudo python3 wifi_deauth.py

Then follow the wizard. The card is only modified after you confirm the prompt on step 1 → 2, and is fully restored by Stop & Reset card.

Selftest

The airodump-ng CSV parser has a self-check that needs no hardware and no root:

python3 wifi_deauth.py --selftest

Limitations

• Scan durations are fixed (10 s / 15 s). Bump SCAN_NET_SECS / SCAN_CLIENT_SECS at the top of wifi_deauth.py if devices are slow to appear.
• The CSV is parsed by naive comma-splitting; an ESSID that contains a comma can shift columns.
• WPA3 / 802.11w (protected management frames) makes deauth ineffective — that is expected, not a bug.
• One client at a time, by design.
