Frequently Asked Questions - MIMO Multiplexer Ubiquiti Networks

How do I set up the MIMO Multiplexer as a Wi-Fi repeater?

Connect the device to your computer via Ethernet, access the web interface (default IP: 192.168.1.2), and follow the setup wizard to scan for your existing Wi-Fi network and enter the password.Make sure the repeater is placed within range of the main router.

What is the maximum range of the MIMO Multiplexer?

The range depends on the environment, but typically up to 100 meters indoors with clear line of sight. Walls and interference can reduce coverage.

Can I use the MIMO Multiplexer with any router?

Yes, it works with any standard Wi-Fi router (802.11 a/b/g/n/ac). It extends the signal of both 2.4 GHz and 5 GHz bands.

How do I reset the MIMO Multiplexer to factory settings?

Press and hold the reset button (located on the back) for 10 seconds until the LED flashes. The device will reboot with default settings.

Does the MIMO Multiplexer support Power over Ethernet (PoE)?

Yes, it supports 802.3af PoE, allowing you to power it through the Ethernet cable using a PoE injector or PoE switch.

What does the MIMO technology improve?

MIMO (Multiple Input Multiple Output) uses multiple antennas to increase data throughput and range by transmitting multiple data streams simultaneously.

Can I manage the MIMO Multiplexer via a mobile app?

Yes, it is compatible with the Ubiquiti UniFi Network app for easy setup and monitoring from your smartphone.

Is the MIMO Multiplexer compatible with Wi-Fi 6?

No, it supports Wi-Fi 5 (802.11ac). For Wi-Fi 6, consider newer Ubiquiti models.

What is the default username and password?

Default credentials are admin for both username and password. Change them after first login for security.

How to update firmware on the MIMO Multiplexer?

Download the latest firmware from the Ubiquiti website, go to the web interface Administration > Upgrade, upload the file, and wait for the device to reboot.

TERMS OF USE: Ubiquiti radio devices must be professionally installed. Shielded Ethernet cable and earth grounding must be used as conditions of product warranty. TOUGHCable ^TM is designed for outdoor installations. It is the customer's responsibility to follow local country regulations, including operation within legal frequency channels, output power, and Dynamic Frequency Selection (DFS) requirements.

airFiber X Compatibility

The airFiber NxN is designed for use with airFiber 5X radios, (model AF-5X) and 5 GHz airFiber X or RocketDish™ antennas.

Note: The airFiber X Antenna OMT Conversion Kit (AF-5G-OMT-S45) is highly recommended when using a RocketDish for proper fitting and improved frequency isolation.

Installation Requirements

• (2) airFiber 5X radios for AF-MPx4
• (4) airFiber 5X radios for AF-MPx8
• airFiber X or RocketDish antenna
- Clear view of the sky for proper GPS operation
- Ground wires – min. 10 AWG (5 mm ² ) and max. length: 1 m. As a safety precaution, ground the airFiber radios to grounded masts, poles, towers, or grounding bars.

WARNING: Failure to properly ground your airFiber radio will void your warranty.

Note: For guidelines about grounding and lightning protection, follow your local electrical regulatory codes.

- Outdoor, shielded Category 6 (or above) cabling and shielded RJ-45 connectors are required for all wired Ethernet connections.

Hardware Overview

airFiber NxN Multiplexer

Chain 0 Connect the antenna RF +45° to this connector.

Chain 1 Connect the antenna RF -45° to this connector.

RF Cables Connect each RF Cable pair to the corresponding RF connection chain on each airFiber 5X radio. For example, connect cable A0 to Chain 0, and cable A1 to Chain 1.

Configure the airFiber 5X Radio

Note: The airFiber 5X radios must be running airOS®F v3.2.1 or newer. The latest firmware is available at: downloads.ubnt.com/airfiber

Each airFiber 5X radio must be preconfigured for use with the airFiber NxN before installing them at the site. Configuration details are available in the airFiber X User Guide, available at: downloads.ubnt.com/airfiber

Enable airFiber NxN support on each radio:

1. Log into the airOS F Configuration Interface.
2. Click the Wireless tab.
3. Enter the additional Cable Loss value (dB):

a. 4.1 for the AF-MPx4, or
b. 7.2 for the AF-MPx8

1. For the NxN Radio setting, select Enable.

1. Click Change, and then click Apply.

Hardware Installation

The following installation shows the AF-MPx8. For the AF-MPx4 installation, only the mounting and connecting of two airFiber 5X radios apply.

1. (For AF-MPx8 only) Attach the 8x8 Radio Bracket to the 4x4 Radio Bracket using four M3x8 Screws.
