Connectivity and compatibility20

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 5 (802.11ac)IEEE 802.11a/b/g/n/ac [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.	1167 Mbps300 + 867 Mbps, AC1200 class; theoretical maximum [2]
Wi-Fi bands — what it means The bands the device broadcasts on. 2.4 GHz reaches further through walls and is needed by many smart devices that work only on it; 5 GHz is faster but fades more behind walls; 6 GHz has the least interference and only newer phones and laptops support it.	2.4 GHz, 5 GHz [1]
WAN (internet) port speed — what it means The maximum speed of the port the provider's cable plugs into. A 100 Mbps port caps the internet at that value even on a faster plan; a gigabit port passes plans up to 1 Gbps, a 2.5 Gbps port faster ones too.	100 Mbps10/100 Mbps port: internet is capped at 100 Mbps even on a faster plan [1]
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.	31 WAN + 2 LAN, all 10/100 Mbps [1]
LAN port speed — what it means The maximum speed of the ports for home devices. A 100 Mbps port caps a connected computer or TV at that value; a gigabit port is needed for fast file transfers and plans above 100 Mbps.	100 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
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 Mbps802.11n, 2×2 [1]
Wi-Fi rate at 5 GHz (max) — what it means The 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 [1]
MIMO per band — what it means How many data streams the device sends at once in each band, for example 2×2 or 4×4. More streams mean a higher peak rate and more headroom when many devices are active at once; most phones use 2 streams.	2×2 (2.4 GHz), 2×2 (5 GHz) [1]
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.	4External omnidirectional: 2 × 2.4 GHz (up to 5 dBi) and 2 × 5 GHz (up to 6 dBi) [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.	6464 devices over 2.4 GHz, 5 GHz and LAN under Xiaomi lab test conditions [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.	NoOnly WPA-PSK/WPA2-PSK is listed [1]
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.	MT7628DA [1]
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.	64 MB [1]
USB port — what it means The router's USB port takes a flash drive or disk for shared file access on the home network, and on some models a 4G modem or printer. Which devices are supported is in the note.	NoneThe interface list has only 3 Ethernet ports, a reset button and the power socket [1]
App — what it means The maker’s app used to set up and control the device.	Mi WiFi (Android, iOS) and web interface [2]
Flash memory (ROM)	16 MB [1]
Wi-Fi standards	IEEE 802.11a/b/g/n/ac, IEEE 802.3/3u [1]
Wi-Fi security	WPA-PSK/WPA2-PSK, black/white list, SSID hiding, unauthorised access prevention [1]

Control and features2

Software features — what it means Firmware features the maker lists for this model. A guest network keeps guests and smart devices apart from the main network, parental control limits time and websites, IPTV/VLAN is needed for some providers' TV service, and auto WAN/LAN detection lets the provider's cable go into any port.	Parental control, one network name for both bands, Wi-Fi scheduleSmart Connect — one name for 2.4 and 5 GHz (enabled in the web interface); 'Healthy mode' turns Wi-Fi off on a schedule; also per-device speed limits and new-device alerts. Guest network, VPN, IPv6 and IPTV are not stated [2]
Firmware	Mi Wi-Fi ROM based on OpenWRT [1]

Housing and installation3

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.	188 × 100.5 × 175 mmAs stated, axes not specified; likely with antennas raised [1]
Weight — what it means The device’s weight without packaging, per the maker.	Not stated by the manufacturer

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.
