Hak5 WiFi Pineapple × ALFA Network Integration Guide

Quick Summary: Hak5 official documentation (docs.hak5.org) explicitly designates the MediaTek MT7612U chipset as the only 802.11ac external adapter guaranteed to work reliably in all penetration testing scenarios. The ALFA AWUS036ACM shares the exact same MT7612U chipset architecture as the Hak5 MK7AC OEM module, but provides higher antenna gain via dual RP-SMA ports and enhanced thermal dissipation for prolonged 5 GHz auditing and PineAP rogue AP campaigns.

Is This Guide for You?​

  • Difficulty: Intermediate.
  • Estimated Time: 20–30 minutes.
  • Skills Used: Terminal commands, Web UI administration.
  • What You Will Achieve:
    1. Correctly connect and identify the ALFA adapter on the WiFi Pineapple.
    2. Configure dual-band 2.4 GHz + 5 GHz Recon scanning and rogue AP broadcasting in the Web UI.
    3. Select optimal antenna configurations for omnidirectional or directional audits.

Why the WiFi Pineapple Requires an External Adapter​

The WiFi Pineapple Mark VII features internal 2.4 GHz radios. To audit modern enterprise 5 GHz (802.11a/n/ac) networks, an external USB radio module is required.

Under embedded OpenWrt kernels, Realtek chipsets rely on out-of-tree drivers that frequently trigger kernel panics during high-throughput packet injection. The MediaTek mt76x2u driver in the AWUS036ACM is compiled directly into the OpenWrt kernel, offering superior DMA buffer reclamation and thermal stability.

Step-by-Step Setup​

Step 1: Hardware Connection & Power​

  1. Plug the ALFA AWUS036ACM into the USB Host port of the WiFi Pineapple Mark VII.
  2. Use a dedicated 5V/3A (15W) power adapter to prevent voltage drop.

Step 2: SSH Verification​

# Verify USB device detection
lsusb
# Expected: Bus 001 Device 003: ID 0e8d:7612 MediaTek Inc. MT7612U

# Check kernel driver binding
dmesg | grep -E "mt76|wlan"
# Expected: ieee80211phy3: mt76x2u registered as wlan3

Step 3: Web UI Configuration​

  1. Open your browser and navigate to http://172.16.42.1:1471.
  2. Navigate to Recon: Select wlan3 (5GHz) from the interface dropdown, check 2.4 GHz + 5 GHz, and click Start Scan.
  3. Navigate to PineAP: Assign wlan3 as the 5 GHz target interface for dual-band rogue AP broadcasting.
