If you're researching for legitimate purposes (security auditing, penetration testing with authorization, or academic study), here's what was commonly available on GitHub in 2021:
While not strictly a GitHub code repository in the sense of a script, the project for the ESP8266 microcontroller was wildly popular in 2021. It allowed anyone to flash a $3 Wi-Fi chip with firmware that creates a web interface to kill Wi-Fi networks. Many GitHub forks of this project appeared, labeled with keywords like "wifi kill" or "jammer."
In many countries, sending unauthorized deauthentication packets is illegal.

: Often called "AP Isolation" or "Privacy Mode," this wireless router setting prevents connected devices from communicating directly with each other. If the attacker cannot talk to your device, they cannot spoof your ARP table.
While software disruption differs technically from hardware radio jamming, regulatory bodies like the FCC strictly penalize intentional interference with wireless communications.
Why was 2021 a significant year for this tool? Run these or with explicit written permission
Ability to kick specific devices or everyone off the network 4.2.2. ARP Poisoning: Uses scapy.all.ARP packets 4.2.2.
Unlike de-auth attacks, ARP spoofing doesn't require a special Wi-Fi card; it works on almost any standard laptop. High "Script Kiddie" Risk: Many 2021 repos were "honeypots" or contained . Users looking to "troll" friends would download an or run a script that actually stole Effectiveness:
Historically, an app called "WiFi Kill" existed for rooted Android devices. By 2021, the original app was largely dead, but its legacy lived on in Python scripts and updated forks. These tools mimicked the functionality: scanning a local network and disconnecting selected devices. if not illegal
Older WiFi standards do not encrypt or authenticate management frames (like deauthentication packets), allowing any device in range to forge them. ARP Trust:
The sophistication in 2021 came from automating the reconnaissance phase: scripts that used airodump-ng to find all nearby clients, then killed everyone except the attacker.
Misuse of these tools can disrupt authorized services and is unethical, if not illegal, when used on networks without permission. Defending Against WiFi Kill
