Specifications checked against the linked manufacturer documents.Checked 18 October 2026
Wi-Fi generation — what it meansThe Wi-Fi standard version: Wi-Fi 4 (802.11n), Wi-Fi 5 (802.11ac), Wi-Fi 6 (802.11ax), Wi-Fi 7 (802.11be). A newer generation brings gains in speed and with many devices only when phones and laptops support it too; older devices still connect but use their own standard. | Wi-Fi 5 (802.11ac)IEEE 802.11ac/n/a (5 GHz), IEEE 802.11n/b/g (2.4 GHz) [1] |
|---|---|
Wi-Fi bands — what it meansThe bands the extender receives and repeats. A 2.4 GHz-only model repeats just that band, which suits smart devices and distant rooms; a dual-band one also repeats 5 GHz for fast phones and laptops. 2.4 GHz passes walls better, 5 GHz is faster but fades more. | 2.4 GHz, 5 GHzDual-band. SmartLink keeps a standby link to the router on the other band and switches to it if the main link drops [1] |
Combined Wi-Fi rate (class) — what it meansThe sum of the maximum Wi-Fi link rates of all bands between the router and your devices, per the maker. On a mobile router internet speed is usually limited by the mobile network rather than Wi-Fi. | 1167 Mbps [1] |
Wi-Fi rate at 2.4 GHz (max) — what it meansThe maximum link rate in the 2.4 GHz band per the standard. This band usually serves distant rooms and smart devices, for which a steady signal matters more than this number. | 300 Mbps802.11n, 2×2, 40 MHz channel [1] |
Wi-Fi rate at 5 GHz (max) — what it meansThe maximum link rate in the 5 GHz band per the standard. This is where fast connections of phones, laptops and TVs near the device run; the value depends on the number of MIMO streams and the channel width (80 or 160 MHz). Not applicable to 2.4 GHz-only models. | 867 Mbps802.11ac, 2×2, 80 MHz channel [1] |
Mesh support — what it meansMesh joins several routers or extenders into one network with one name: a phone moves to the nearest node by itself. Brand mesh works only with compatible models of the same brand (for example HUAWEI Mesh+ or Xiaomi Mesh), EasyMesh with supporting devices of different brands. A wired link between nodes (Ethernet backhaul) keeps speed up between floors. | Not stated by the manufacturer |
Ethernet port count — what it meansHow many RJ45 sockets the router has. Pocket models usually have none; on desktop ones a computer, TV or another router plugs into the port. | 1The port can connect a wired TV or game console [1] |
Ethernet port speed — what it meansThe maximum speed of the extender's Ethernet port. At 100 Mbps, a device connected by cable, or the link to the router in access point mode, will not exceed that value. | 100 Mbps [1] |
Number of antennas — what it meansHow many antennas the device has; whether they are external or built-in and how they are split between bands is in the note. The antenna count alone is not the same as coverage, which also depends on transmitter power, walls and placement. | Not stated by the manufacturer |
Antenna type — what it meansExternal antennas can be turned to aim the signal where you need it; built-in ones are hidden in the housing, making the device more compact. | Not stated by the manufacturer |
Max. connected devices — what it meansHow many devices can join the router's Wi-Fi at once, per the maker; any beyond that number will not connect. | Not stated by the manufacturer |
WPA3 encryption — what it meansWPA3 is the current Wi-Fi security standard and better protects the network password against guessing. Without it the device uses WPA2; some older smart devices connect only to WPA2, so a mixed WPA2/WPA3 mode is usually available. | NoOnly WPA-PSK / WPA2-PSK is listed; WPA3 is not in the specifications [1] |
App — what it meansThe maker’s app used to set up and control the device. | Mi Home / Xiaomi Homesetup also via the WPS button [2] |
Processor / radio chip — what it meansThe microcontroller or radio module inside, per the maker (for example ESP32). For firmware such as WLED and ESPHome it determines available features and whether the device can be re-flashed. | Not stated by the manufacturer |
| Wi-Fi standards | IEEE 802.11ac/n/a (5 GHz), IEEE 802.11n/b/g (2.4 GHz) [1] |
| MIMO configuration | 2×2 (2.4 GHz), 2×2 (5 GHz) [1] |
Transmit power — what it meansThe coordinator's maximum radio output. Higher power gives a steadier link to distant devices, but range in a home depends more on walls and the number of routers in the network. | < 20 dBm (2.4 GHz), < 23 dBm (5 GHz) [1] |
| Wi-Fi security | WPA-PSK / WPA2-PSK [1] |
RAM — what it meansThe amount of RAM per the maker. The firmware uses it for the connection table and features such as VPN and parental control; with many devices, spare memory affects stability. | 64 MB [1] |
Operating modes — what it meansAs a repeater the extender picks up the router's signal over Wi-Fi and rebroadcasts it. In access point mode it takes internet over a cable and creates Wi-Fi where a cable is already run, without the speed loss of rebroadcasting. Adapter mode connects a device without its own Wi-Fi (TV, set-top box, computer) to Wi-Fi via a cable. | Repeater (range extender), access point (internet via cable)Range extender mode and access point mode (internet by cable from the router into the Ethernet port) [1] |
|---|---|
WPS button — what it meansConnects to the router by pressing the WPS button on both devices, without entering a password or using an app. Works if the router has WPS and it is enabled. | YesWPS setup: press WPS on the router, then on the extender within 2 minutes [2] |
| Indicators and buttons | WPS button, reset button; signal LED (blue strong, orange weak, red disconnected) and system LED [2] |
Mounting — what it meansHow and where it is installed: in a wall box, on a wall or ceiling, on a DIN rail, on a table or in a socket. | Plugs into a socketPlugs directly into a wall socket; dimensions vary with the regional plug type [2] |
|---|---|
Dimensions (W × H × D) — what it meansThe device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf. | 84 × 100 × 82 mmDimensions vary between regions due to the plug shape [1] |
Weight — what it meansThe device’s weight without packaging, per the maker. | Not stated by the manufacturer |
Colour — what it meansThe housing colour of this model. Other colours in the same series are separate products. | Black [3] |
|---|
Rated power — what it meansThe rated or maximum power draw from the spec sheet. It sets the load on the socket and the energy use. | Not stated by the manufacturer |
|---|---|
Supply voltage — what it meansThe supply voltage (and current, if stated) as the maker gives it. It must match your mains or adapter. | 100–240 V AC, 50/60 Hz, 0.3 A (plug on the housing) [1] |
Standby power — what it meansHow much power the device draws on its own while idle. It matters for devices that run around the clock. | 2.5 WUp to 2.5 W; 3.1 W with all ports connected and all radios active [2] |
Operating temperature — what it meansThe air temperature range the device is rated for. The lower limit matters outdoors, on balconies and in unheated rooms. | 0–40 °C [1] |
|---|
Package contents — what it meansWhat comes in the box, per the maker. | Mi WiFi Range Extender, user manual, warranty card [1] |

In your home
A fast broadband plan does not fix weak signal through a wall. Several apps do not become one system by themselves. Placement and verified connections matter.
