Mikrotik R11e-5HacD Mini PCIe 802.11ac Card - High Power Upgrade

In this review the Mikrotik R11e-5HacD is evaluated as a high-power miniPCIe wireless card aimed at users who need an upgraded 802.11ac radio for RouterBOARD or x86 devices running RouterOS. The bottom line: this card is for networking pros and integrators who want up to 866 Mbit throughput, 80 MHz channel support and the flexibility of a miniPCIe form factor with 2x MMCX antenna connectors. Our review finds the R11e-5HacD delivers notable throughput and alignment convenience thanks to onboard LED indicators, making installation and troubleshooting faster than many internal cards.

Key Features

• 802.11ac performance: The card supports the AC standard with up to 866 Mbit datarate, enabling faster wireless links for backhaul or high-capacity client aggregation.
• High transmit power: With a 500 mW power rating, the card is suited to long-range links and environments where stronger signal penetration is needed.
• MiniPCIe form factor: Fits RouterBOARD devices with a miniPCIe slot and many x86 boards running RouterOS, making upgrades straightforward.
• 2x MMCX antenna ports: Dual external antenna connectors provide flexibility for directional or sector antennas to shape coverage and improve link quality.
• Built-in LEDs: Onboard indicators for wireless mode, connection status, TX/RX activity and signal strength simplify installation and alignment without extra tools.
• Wide modulation support: 256-QAM and 80 MHz channel capability open higher throughput modes when paired with compatible equipment.

Who It's For

The R11e-5HacD is best for network integrators, wireless ISPs, and advanced users who operate RouterBOARD platforms such as RB953, RB912, RB922 or RB800, or run RouterOS on x86 hardware. It is particularly useful when upgrading existing miniPCIe systems to 802.11ac for higher datarates and when external antenna choice is important.

Those looking for a plug-and-play consumer USB adapter or a fully enclosed access point should look elsewhere; this is an internal module that assumes some familiarity with RouterOS configuration and hardware installation.

Pros & Cons

Pros

• High throughput potential with 802.11ac and 80 MHz channels for demanding links.
• 500 mW output gives better range and link stability compared with low-power cards.
• Onboard LEDs and dual MMCX connectors make alignment and antenna selection easier on install.

Cons

• Designed for RouterBOARD and RouterOS environments, so it is not a simple consumer plug-in option.
• Requires compatible miniPCIe slot and external antennas, adding installation complexity for some users.

Specifications

Our Verdict

The Mikrotik R11e-5HacD is a practical, high-value upgrade for RouterBOARD and RouterOS users who need stronger links and faster wireless throughput. It combines 802.11ac performance with high transmit power and helpful onboard LEDs, making it a solid choice for installers and pros who can handle miniPCIe integration.

Frequently Asked Questions

Will this work in my RouterBOARD?
The card is designed for RouterBOARD models with a miniPCIe slot such as RB953, RB912, RB922 and RB800; confirm your board exposes a compatible slot before purchasing.

Do I need external antennas?
Yes, the R11e-5HacD uses 2x MMCX connectors for external antennas, so choose antennas suited to your link goals.

Is it compatible with standard PC motherboards?
It can work in x86 devices running RouterOS if the board provides a miniPCIe slot and proper antenna routing, but it is not a general-purpose consumer adapter.
