Connectivity and compatibility17

Wi-Fi generation — what it means The 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 4 (802.11n)IEEE 802.11b/g/n [1]
Wi-Fi bands — what it means The 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 GHz2.4 GHz only; the 5 GHz band is not repeated [1]
Combined Wi-Fi rate (class) — what it means The 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.	300 MbpsN300 class: 2.4 GHz band only, 2×2 antennas [1]
Wi-Fi rate at 2.4 GHz (max) — what it means The 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 Mbps [1]
Mesh support — what it means Mesh 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 means How many RJ45 sockets the router has. Pocket models usually have none; on desktop ones a computer, TV or another router plugs into the port.	Not stated by the manufacturer
Ethernet port speed — what it means The 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.	Not stated by the manufacturer
Number of antennas — what it means How 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.	22 external antennas (2×2), both for 2.4 GHz [1]
Antenna type — what it means External 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.	External [1]
Max. connected devices — what it means How many devices can join the router's Wi-Fi at once, per the maker; any beyond that number will not connect.	16'Up to 16 devices connected simultaneously' [2]
WPA3 encryption — what it means WPA3 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.	NoWPA-PSK / WPA2-PSK encryption [1]
App — what it means The maker’s app used to set up and control the device.	Mi Home / Xiaomi HomeThe app is used to add the device and to find a spot with a steady router signal [2]
Processor / radio chip — what it means The 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.	MediaTek MT7628K, 580 MHz [1]
Wi-Fi security	WPA-PSK / WPA2-PSK [1]
Connectivity — what it means The wireless link or network the device uses. Wi-Fi connects straight to the router; Zigbee, Thread and Bluetooth Mesh work through a hub or gateway.	Wi-Fi [1]
Hub required — what it means Whether the device needs a separate hub, gateway or coordinator to work in a smart home. If so, it is sold separately unless stated otherwise.	No hub neededNo hub is needed, but an existing Wi-Fi router whose signal is extended is required [2]
RAM — what it means The 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.	8 MB [1]

Control and features2

Operating modes — what it means As 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)The maker describes only the repeater mode (wireless connection to the router). Access point and adapter modes are not mentioned [2]
WPS button — what it means Connects 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.	Not stated by the manufacturer

Power3

Rated power — what it means The rated or maximum power draw from the spec sheet. It sets the load on the socket and the energy use.	3.57 W [1]
Supply voltage — what it means The supply voltage (and current, if stated) as the maker gives it. It must match your mains or adapter.	100–240 V, 0.35 A [1]
Power source — what it means Where the device gets its power: 230 V mains, an adapter, USB, batteries or a built-in battery.	230 V mains [1]

Housing and installation3

Mounting — what it means How 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 socketThe plug is built into the housing; official photos show a European-type plug [2]
Dimensions (W × H × D) — what it means The device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf.	80 × 54 × 70 mmThe maker does not specify the order of the dimensions [1]
Weight — what it means The device’s weight without packaging, per the maker.	Not stated by the manufacturer

Model and version2

Colour — what it means The housing colour of this model. Other colours in the same series are separate products.	BlackPer official photos; the model has a black housing [2]
Manufacturer model	R03 [1]

Operating conditions4

Operating temperature — what it means The air temperature range the device is rated for. The lower limit matters outdoors, on balconies and in unheated rooms.	0–40 °C [1]
Operating humidity — what it means The rated relative humidity range, non-condensing.	10–90%Non-condensing [1]
Storage temperature	−40…70 °C [1]
Storage humidity	5–90 % RH, non-condensing [1]

Delivery, payment and returns

In your home

A reliable connection underpins your smart 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.

What to check before buying

We clarify the floor area and number of levels, where the provider’s router sits, which rooms matter for work and video, and whether cable can be run. Real speed also depends on your internet plan and the device itself.
