⚡ Dual-Band Deauth Engine

" "

⚠ WARNING: Use ONLY on networks YOU OWN! Unauthorized use is ILLEGAL!

" "

💡 This attacks BOTH 2.4GHz and 5GHz targets SIMULTANEOUSLY by rapid channel switching.
" "⚠ WiFi AP will be OFFLINE during attack and auto-restore after.

" "

🎯 Selected Targets

Scan networks first, then select targets

⚙ Attack Configuration

" "

Duration: seconds

" "

10-300 seconds recommended. AP auto-restores after attack.
