WiFi Pineapple: MK7AC Adapter (Hacking Hardware)

WiFi Pineapple: Tactical (MK7AC Adapter) 5 GHz Add-on

The MK7AC is Hak5's official dual-band USB adapter that adds 802.11ac (5 GHz) capability to the Mark VII, which ships with only 2.4 GHz radios built-in. Here's everything that matters:

Hardware Specs

Detail	Value
Chipset	MediaTek MT7612U
WiFi Standards	802.11 a/b/g/n/ac (WiFi 5)
Bands	2.4 GHz + 5 GHz
Interface	USB 3.0 (USB-C, with included USB-A adapter)
Antennas	2x RP-SMA (high gain, removable)
Throughput	Up to 866 Mbit/s
Dimensions	33 × 44 × 20 mm (compact dongle)
Monitor Mode + Injection	Fully supported

Why You Need It

The Mark VII's internal radios are 2.4 GHz only. In any real engagement, 5 GHz is critical because:

• Modern enterprise and residential networks heavily use 5 GHz (and increasingly 6 GHz WiFi 6E, but that's separate).

• Many clients prefer 5 GHz and won't probe for 2.4 GHz.

• Without 5 GHz, you're blind to half the traffic and can't lure clients away from 5 GHz APs via deauth + PineAP.

Setup - Practically Zero Configuration

With the Mark VII running firmware 2.0+, you literally plug the MK7AC into the USB port and Pineapple OS auto-detects it. PineAP and all modules immediately gain access to both bands — "full band attacks" as Hak5 puts it. The web dashboard will show the new radio under Networking and you can assign it to recon, PineAP, or management roles.

The USB port on the Mark VII is USB 2.0 host (the USB-C port is primarily power/Ethernet), so the MK7AC connects via the included USB-C-to-USB-A adapter into that host port, not the power port. This is a common point of confusion — it goes into the USB 2.0 host port (the rectangular one), not the USB-C power port.

Standalone Use

The MK7AC isn't locked to the Pineapple. It uses the standard MT7612U chipset which has mainline Linux kernel support (mt76 driver). You can unplug it and use it directly on any Kali/Parrot/Ubuntu box with:

bash

# Verify it's detected
lsusb | grep MediaTek

# Check interface
iwconfig

# Enable monitor mode
sudo airmon-ng start wlan1

# Or use with bettercap
sudo bettercap -iface wlan1

It works with aircrack-ng, kismet, bettercap, hcxdumptool, and anything that speaks monitor mode + injection over mt76.

Compatible Third-Party Alternatives

Since the MK7AC is just an MT7612U dongle, three officially compatible alternatives exist (per Hak5 docs):

• Alfa AWUS036ACM — most popular alternative, widely available, same chipset

• EP-AC1605 V1 — works, but V2 is incompatible (different chipset)

• Any other MT7612U-based adapter

Additionally, Pineapple OS has out-of-the-box support for MT7601U, and you can manually install drivers for ath9k, ath10k, and some Realtek chipsets via opkg.

Practical Limitations

• No 6 GHz (WiFi 6E) — the MK7AC is WiFi 5 only. For 6 GHz you'd need an AX210/AX211-based adapter with separate driver installation, and support is patchy on the Mark VII's OpenWrt base.

• USB 2.0 host port bottleneck — the Mark VII's host port is USB 2.0, so you won't get the full USB 3.0 throughput the adapter is capable of. For passive monitoring this doesn't matter; for high-throughput injection it's a mild constraint.

• One adapter at a time — the Mark VII has a single USB host port. If you want multiple 5 GHz radios for simultaneous multi-channel monitoring, you'd need a powered USB hub, and YMMV.

Pro Tips

• Position the MK7AC antennas differently from the Mark VII's built-in antennas to minimize self-interference.

• If you're doing a stationary assessment, use SMA extension cables to separate the MK7AC antennas from the Pineapple body for better signal isolation.

• The MK7AC gets warm under sustained load — this is normal for MT7612U dongles, but keep airflow in mind for long engagements.
