Xiaomi N300

Manufacturer: Xiaomi

The Xiaomi N300 is a compact Wi-Fi extender designed to expand wireless coverage in homes and small spaces. Built around a single-band Wi-Fi 4 (802.11n) architecture, it delivers up to 300 Mb/s of wireless throughput while keeping energy consumption notably low at just 3.57W during operation. Its modest physical footprint — 80 mm tall, 70 mm wide, and 54 mm thick — makes it easy to place discreetly wherever additional coverage is needed.

On the feature side, the N300 includes beamforming and MU-MIMO support, which help focus the wireless signal and handle multiple connected devices more efficiently. Security is covered through WPA and WPA2 protocols. The unit ships with two external antennas and has a total volume of 302.4 cm³. It does not include LAN ports, a WPS button, mesh Wi-Fi capability, or a dedicated smartphone management app.

Pros
  • Beamforming support helps direct the wireless signal toward connected devices for more consistent coverage
  • MU-MIMO capability allows multiple devices to receive data simultaneously rather than in sequence
  • WPA2 security protocol provides a solid level of wireless network protection
  • Very low operating power consumption of 3.57W keeps energy usage minimal during continuous use
  • Compact dimensions make it easy to position in tight or inconspicuous spaces
Cons
  • Single-band Wi-Fi 4 limits maximum throughput to 300 Mb/s, which may not satisfy bandwidth-heavy households
  • No LAN port means wired device connections are not possible
  • Mesh Wi-Fi is not supported, restricting its use in larger multi-node network setups
  • No WPS button makes connecting devices slightly less convenient
  • Lacks a dedicated smartphone app, so users cannot manage the extender through a mobile interface
Who is this for?

This extender is well-suited for users in small spaces or single-room environments where modest wireless coverage is all that's needed. Its low power draw and compact build make it a practical fit for those who want a simple, unobtrusive device that stays on continuously without adding noticeably to energy consumption. Users with a limited number of connected devices will also benefit from its MU-MIMO and beamforming support, which help maintain stable connections for light to moderate everyday tasks like browsing, streaming at standard quality, or handling smart home accessories.

Who is this NOT for?

Users with high-bandwidth demands — such as 4K streaming, large file transfers, or online gaming — will likely find the 300 Mb/s ceiling restrictive. The absence of a LAN port makes it unsuitable for anyone needing wired device connectivity through the extender. It is also a poor fit for larger homes or multi-floor setups, as it does not support mesh Wi-Fi and cannot be integrated into a distributed network system for seamless whole-home coverage.

General info:

Wi-Fi version Wi-Fi 4 (802.11n)
Wi-Fi speed 300 Mb/s
Wi-Fi bands Single-band
operating power consumption 3.57W
LAN ports 0

The Xiaomi N300 operates on a single-band Wi-Fi 4 (802.11n) network, offering a maximum wireless speed of 300 Mb/s. It has no LAN ports, making it a purely wireless extender by design. During normal use, the device draws just 3.57W of power, reflecting a notably lean energy profile for everyday operation.

The N300 has a compact build, measuring 80 mm tall, 70 mm wide, and 54 mm thick, with a total volume of 302.4 cm³. It is equipped with two external antennas, which sit outside the main body to assist with wireless signal distribution.

Final Verdict

The Xiaomi N300 is a straightforward Wi-Fi extender that delivers on its core purpose for the right audience. Its beamforming and MU-MIMO support give it a practical edge in managing multiple simultaneous connections within a limited range, and its remarkably low power consumption makes it a sensible choice for always-on deployment. That said, its single-band Wi-Fi 4 foundation and lack of LAN ports or mesh support clearly place it in the category of light-duty solutions. For users in small spaces with modest connectivity needs, the N300 is a functional and energy-efficient option — but those with more demanding network requirements will need to look beyond what this device is designed to offer.
