Measured millet WiFi amplifier wall is good

The house is too big and the router signal is too bad, and the network is unstable, making the downcast party, who is a big family, miserable. WiFi signal is a headache for big houses. In order to solve the signal problem, most people may choose to purchase signals and routers with better wall-to-wall or routing bridges to achieve an increase in WiFi area. The demand for WiFi signal amplifiers has also been increasingly favored by machine users.


WiFi signal amplifiers on the market are varied, some are oversized, some are inconvenient, and others are expensive. But personally, I was not very optimistic about the WiFi signal amplifier, mainly considering his signal-passing capability. It may not be as good as a router, but it is also ugly. Therefore, what I expected at the beginning was to use route bridging if the signal coverage in my home was incomplete in order to achieve full coverage of the room signal.

While releasing the new millet router, Xiaomi also released a router accessory, the Xiaomi WiFi amplifier. The first impression of this signal amplifier is that it is compact, cheap, and better than the WiFi amplifier on the market. In fact, we are more concerned with his signal amplification capabilities and stability, so to bring everyone an inexpensive millet WiFi amplifier experience.

Millet WiFi amplifiers use plastic packaging, which may not be cartoned for price reasons. The whole WiFi amplifier body is made of white plastic. The body length is 121mm, width is 28mm, thickness is 8mm, and the whole length is similar to a signature pen. The flat design of the bar may make people at first glance not see his function, and more people may think of it as a large U disk or an external antenna.

Although the function cannot be seen through the appearance, the related function can be identified through the logo on the outer shell. There is a logo and reset hole and indicator on the side of the shell. On the other side, a “WiFi” logo is printed. . Millet WiFi amplifier is divided into two parts, a part of the motherboard part is a long section, while the other part is the USB side can be disassembled to change direction.

USB2.0 interface


Millet WiFi amplifier uses a standard USB2.0 interface as a power supply and data interface, taking into account the needs of different environments, the USB interface is designed as a rotary interface, up to 180 ° adjustable design. In terms of personal feelings, this 180-degree rotating USB interface phone makes this WiFi amplifier more practical, and it can basically adapt to the wide and narrow environment.

Millet WiFi amplifier from the side of the past, perhaps at the first glance I feel that it borrowed from the millet router mini design style, especially the USB interface at the round shell design and mini circular similarity of up to 90%. The body thickness of 8mm makes it almost the same as the thickness of a signature pen. At the same time, the model, ID number and manufacturer of the millet WiFi amplifier are also printed on the side of the side, so that everyone can understand the product information more clearly.

For millet WiFi amplifiers, besides the unique 180° rotation USB interface, it's even easier to install. The millet WiFi amplifier installation requires only two steps. First, insert the Xiaomi WiFi amplifier into the router that you want to match, and then complete the relevant settings through the Xiaomi smart home. Of course, if the home is using a new millet router, you can directly save the above two steps of the installation process, until the millet WiFi amplifier self-fitting can be used normally.


If you find that you can't complete the adaption or find the device when you first use it, you can use a pin or pin to reset the millet WiFi amplifier through the reset hole, and then perform related operations. Another highlight is its flexibility, which can be plugged into any USB power port after the first fit, such as a patch panel with a USB interface, a mobile power supply, a computer, or even you can connect it with an OTG cable. Mobile phones can be connected.

For non-new millet router users and Xiaomi WiFi amplifier management, Xiaomi Smart Home APP is a must-have mobile application. From the perspective of the connection between the APP and the WiFi amplifier, it is not complicated. When you open the Xiaomi Smart Home App, the phone will automatically prompt you to find the Xiaomi WiFi amplifier device, and then complete the relevant configuration and connection according to the prompts. The Xiaomi WiFi amplifier network name is also more obvious, mainly in our original WiFi network name plus a "_plus" characters.

In order to detect the signal amplification ability and stability of the millet WiFi amplifier, the channel, signal strength, download and upload speeds were tested in a 4M network environment in different rooms through WiFi Analyzer and SpeedTest software. Because the wall thickness of the room is about 20CM, the results are tested when the router signal is relatively weak.

In the same room, the signal of the Xiaomi WiFi amplifier is not as good as the room where the router signal router signal is slightly cut. The signal amplification capability of the Xiaomi WiFi amplifier is highlighted and far exceeds the router signal.

Poor router signal room, millet WiFi amplifier is also higher than the router signal

Through the test results, it can be found that the Xiaomi WiFi amplifier and the router in the same room and the signal in a relatively good area can fully reflect the signal amplification ability of the Xiaomi WiFi amplifier, but its signal capability is still not as good as the signal strength of the router itself; in the poor signal room In addition, although the Xiaomi WiFi amplifier can receive the signal from the router and the instability of the signal from the router becomes unstable, the download and upload test results of the network in any area have certain differences, but it is also considered as satisfaction. In terms of wall penetration ability, by placing it in a room, a router in the living room, and then testing in another room, the signal is almost the same as the router.


In general, the Xiaomi WiFi amplifier is simple, compact, easy to install, and relatively inexpensive. It belongs to the general public. In a small room that can receive stable routing signals, it can amplify the signal of the route a lot, stability is better, and it is also considered to be very good in wall penetration. Therefore, Xiaomi WiFi Amplifier is a small thing that everyone can afford to use, and it is also a necessary artifact that can make a big house have a good network.
