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.

1. Hardware Topology & Architecture​

The WiFi Pineapple Mark VII features two internal 2.4 GHz radios (wlan0 for AP Client/Management, wlan1/wlan2 for PineAP broadcasting and Recon scanning). To audit modern enterprise 5 GHz (802.11a/n/ac) networks, an external USB radio module is required.

Why Hak5 Officially Specifies MT7612U​

Under embedded OpenWrt kernels, Realtek chipsets (such as RTL8812AU / RTL8814AU) rely on out-of-tree drivers that frequently trigger kernel panics or spontaneous reboots during high-throughput packet injection and multi-SSID beacon floods. The MediaTek mt76x2u driver is compiled directly into the OpenWrt kernel, offering superior DMA buffer reclamation and thermal stability.

3. Step-by-Step Configuration​

Step 1: Hardware Connection & Power Budget​

  1. Plug the ALFA AWUS036ACM into the USB Host port of the WiFi Pineapple Mark VII.
  2. Critical Power Requirement: The WiFi Pineapple Mark VII consumes 3W~5W, and the AWUS036ACM draws up to 4.5W (900mA @ 5V) during peak 5 GHz transmissions.
    • ❌ Avoid: Unpowered laptop USB ports (500mA limit) or weak 5V/1A adapters.
    • ✅ Recommended: Dedicated 5V/3A (15W) AC adapter or high-output QC/PD power bank.

Step 2: SSH Terminal Verification​

Connect to the WiFi Pineapple via SSH (172.16.42.1):

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

# 2. Check kernel driver binding
dmesg | grep -E "mt76|wlan"
# Expected: mt76x2u 1-1:1.0: firmware: mt7662u.bin loaded
# Expected: ieee80211phy3: mt76x2u registered as wlan3

# 3. Confirm wireless interface status

Step 3: Web UI 5 GHz Recon & PineAP Setup​

  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.

4. Antenna Recommendations​

  • Omnidirectional 360° Audits: 2× ALFA ARS-NT5B7 5dBi/7dBi dual-band antennas.
  • Long-Range Directional Audits: 2× ALFA APA-M25 8dBi/10dBi dual-band directional panel antennas (60° horizontal beamwidth).

5. Troubleshooting​

Q1: Pineapple reboots immediately when AWUS036ACM is plugged in​

  • Root Cause: USB inrush current causing voltage drop.
  • Fix: Connect the AWUS036ACM prior to powering on the Pineapple, and use a 5V/3A power supply.

Q2: Interface conflicts with previous USB adapters (wlan2 collision)​

  • Root Cause: Stale /etc/config/wireless configuration.
  • Fix: Run rm -f /etc/config/wireless && wifi config && /etc/init.d/network restart.
