Xiaomi_Mi_WiFi_Router_3

The router runs MiWiFi operating systems with configuration via its web interface, Android or  iOS apps. I understand that the router’s web interface is only in Chinese, but the apps also support English. However, the original router also supports OpenWrt, and considering there aren’t that many differences, the new version should already or soon be supported. You may find more details on the product page in Chinese.

Help me understand why you’ve got a wireless throughput of up to 867 Mbps and you then cripple that with a wired throughput of 100 Mbps. If I’ve got a Gbps network set up then best case is that my wireless devices are capped at 100 Mbps talking to wired machines and worst case is that this device slows my entire network down to 100 Mbps.

Are these solely for wireless devices that connect straight to the internet over a connection that’s capped at 100 Mbps ?

According to other sellers this is a gigabit router. Can’t wait for an English firmware.

It seems to be trend, other recent chinese routers for the china market on another well known site are also 10/100 yet all claiming gigabit, they are being sold as though Cat 5e is so so last year, and its our fault for not using wifi, with broadband now getting upwards of 200-300mbit, erm kinda shots itself in the foot.

Do any ‘so called’ 300/867Mbs WiFi routers really deliver sustained throughput in the >100Mbs range? Aren’t they like ‘so called’ 500Mbs Powerline adaptors (also usually sold with 100Mbs connections)? The claimed speeds are seldom anywhere near what they achieve in real-world situations.

SOC can not be 7620A, it must 7621A which dual core. MT7620a is only two radio 802.11n and no 802.11ac

I believe that the product is called “MiWiFi”, not “Mi WiFi” (even though it is part of Xiaomi “Mi” series).

Anyway, unless you are an OpenWRT developer yourself I would wait until they add support for this:

Looks like very capable hardware for the price, wonder when a three band model will come out?

I this were a gigabit router then yeah sure but since it’s not, no thanks. I still care about wired performance and sometimes those 4 gigabit ports come in really handy.

MT7620A supports up to 5 Fast Ethernet ports and 2 Gigabit Ethernet ports. The difference is that the FE ports include the PHY and gigabit ports don’t. An external gigabit phy nowadays costs less than 1 dollar, but they prefer to ship a deceptive product.

Archer C7 TP-LINK is the cheapest I could find. Not xiaomi cheap though. Some people say it’s good but I have no experience with it.

Yes, Xiaomi specs say 100Mbps.
No, the ‘A’ variant of the SoC used in this device has two RGMII interfaces. The ‘N’ variant has an integrated PHYs for 5 fast ethernet ports and no RMIIs.

The spec above is missing lots of important parts: What is the Tx power, Rx Sensitivity (dBm), Antenna gain dB, is there a Guest Account, and of course the typical energy consumption (not the power brick capability) given that it will probably be on 24/7. I would like to see a full test under OpenWRT before considering it further.

Wrong on so many fronts.

Most dual-band routers use a second chip for the 5GHz band, and the WiFi SoC for the 2.4GHz band.
This device is no different, as explained by the other commenter.

Moreover, the MT7621 SoCs don’t have ANY integrated WiFi, and so dual band routers based on them typically include two WiFi chips, one for 2.4GHz and one for 5GHz.

Beyond that, there are multiple offerings in the MT7621 family, including a single core version.

@Harley Xiaomi has a few higher end products. I’d expect their first 3-band offering to appear at those higher price points. Agree about the OpenWRT support. I have the earlier, two antenna, version of this device. It is nominally supported in 15.05.1, but I’ve found it to have serious problems in AP mode, particularly on the 5GHz radio. For that device, the stock firmware is OpenWRT based, but depends on proprietary binary drivers and other non-standard enhancements. There are also 3rd-party OpenWRT based firmwares that use more of OpenWRT, but still depend on binary drivers. I think its good to… Read more »

I can easily get speeds of 300-400 Mbps with a decent USB antenna (not a tiny dongle, mind) and the R7000. That’s in the same room, though. It drops to 60-80 Mbps through two brick walls.

Did anyone got any idea how many wifi user can be support by this Xiaomi Mi WiFi Router 3 Dual Band APP Control with 4 Antenna? So this router wouldn’t hang or lacking . Just thinking can this be use & replace the original router from ISP in church building?

Question I have one of these working fine on the wireless network, I get ~90Mbps downlaod which is far better than I was getting with the old cisco router (now Bridged) one issue I’ve noticed is that the wired ports are only providing ~2Mbps. I know they’re 10/100 but I thought they would be able to handle more than that. Does anyone know if there is a setting missing? Oh and my internet speed is 240M, i tested the wired network just before switching to bridge mode and was getting ~215M. I uise this over cat5e in the walls to… Read more »

Hi !
I’m also interested about a new gigabit router. My network is in gigabit and my internet is in fiber optic (France – 800mb/s).

No news from Xiaomi?
