Xiaomi WiFi Router 3G Review

The best budget wireless router – Xiaomi Mi WiFi Router 3 just got upgraded. – Xiaomi WiFi Router 3G is the enhanced version of it with better CPU – MT7621A MIPS dual-core 880MHz processor (Xiaomi Wireless Router Pro uses it too). Same internal 128MB SLC Nand Flash but double up and upgraded 256MB DDR3-1200 RAM. There is USB 3.0 port this round and comes with Gigabit Ethernet. As usual, it supports dual band 2X2 networks – 2.4GHz 300Mbps N and 5GHz 867Mbps AC. How does it perform? Let’s find out together…

Special Thanks
This review is possible thanks to below companies. Be sure to check them out too…

Package Content & Design
Packaging is the same as previous version but comes with bright orange colour this time. There is no global English version yet. But you can install Taiwan English firmware later when it comes out. Yes, all the information is in Chinese for China model. There are US plug power adaptor and user manual. FYI, the new AC adaptor has 1.5A compare to 1A only previously. Build quality is better too.

Xiaomi WiFi Router 3G build quality is decent with solid white plastic frame. Ultra light in weight too. Basically, both models are the same. Just 3G has USB 3.0 and 2 LED lights on Ethernet ports.

Besides that, there is a heatsink added inside the casing too. Powerful processor requires better cooling I believe.

Yes, just like Chinese version of Xiaomi Wireless Router Pro that I have. Xiaomi WiFi Router 3G supports installation via English Mi Wi-Fi app (can be found at Play Store and App Store for both Android and iOS devices). Simple and fast as usual. Basically, you need to power on it. Then connect your cable/DSL modem Internet cable to WAN port. Use smartphone to connect to Xiaomi WiFi Router 3G Wi-Fi. Then use MiWiFi App to setup Wi-Fi network name & password (you can set different admin password too). That’s it. You can start to use Xiaomi WiFi Router 3G now and access to Internet.

FYI. If you don’t have MiWiFi App, and are stuck with Chinese web interface. No worry, Google Chrome translator can help you.

It is either Mi Wi-Fi English application or web interface with Chrome translator. Personally, I use mobile app more than web interface as I can access it anywhere I want instead of using PC. As usual, there certain wordings are still in Chinese in Mi Wi-Fi app. No worry, those are not critical stuffs and all the important stuffs are working as usual. And Xiaomi added more goodies since my Xiaomi WiFi Router 3 Review. Enjoy all these useful features like guest network, security (firewall), Wi-Fi boost, photo backup, QoS, Wi-Fi timer, SAMBA, schedule reboot and more…

Yes, the built-in download manager (Xunlei) is there for you as usual. Just attach external USB hard drive to USB 3.0 port, you can turn Xiaomi WiFi Router 3G into local NAS that store downloaded movies, photos and music.

Performance Result
I use US$200 Asus RT-AC68U router (Jayce-ASUS) + $30 Xiaomi WiFi Router 3 (iCity2u) as comparison this round. As usual, all of them are placed at the same spot on 1st floor. And screenshots below was taken while I was on ground floor. Basically, both 2.4GHz and 5GHz range performance are the same on these budget routers. 3G version does have better 2.4GHz range a bit as you can see.

Mi Router 3G supports 2T2R too. I manage to get up to 150Mbps on 2.4GHz connection and 866Mbps on 5GHz on my Windows 10 PC. 72Mbps and 433Mbps for devices that don’t support 2T2R.

Yes, 4K ultra high definition videos are supported with Gigabit Ethernet from below iPerf3 result. That’s the maximum transfer rate for my devices through LAN. As for wireless, 90Mbit/s for 2.4GHz and 220Mbit/s for 5GHz on 2T2R. Better performance than previous version no doubt.

Yes, network-attached storage (NAS) alike performance is here too. Up to 100MB/s for reading from USB HDD through Gigabit Ethernet. Writing at 40MB/s by the way. And there is no system slow down at all when there is someone transfer file to/fro USB hard drive with newer powerful CPU. More RAM helps too I believe. Easily serve up to 10 devices smoothly on basic Internet surfing with some USB HDD files transferring. No slow down on real-time online gaming too. That’s great.

Any complaint? Yes, a critical one for me. You can’t read file from USB HDD through 5GHz wireless connection. It just hang there doing nothing on current latest firmware. No worry, this will (/must) be fixed in future firmware by Xiaomi. It can use some stability improvement as well. Therefore, it is recommended to set scheduled reboot everyday on early firmware versions until the stable ones come out.

Update – 5GHz file reading issue had been fixed by Xiaomi on firmware 2.24.326. Furthermore, they improved overall system stability.


  • Support up to 1167Mbps & Gigabit Ethernet

  • Packed with lot features
  • Built-in download manager
  • Value in price


  • Firmware still need to be improved

Xiaomi WiFi Router 3G is a budget yet performing wireless AC router no doubt. Loaded with lot of useful features. As usual, it performs best in small area. Interested? Do visit GearBest Website for more information.


  1. Hi!

    This article is murkily written. I can’t tell what are the transfer speed from where.
    What’s the LAN-LAN, and WAN-LAN transfer rate? Is the table with the 930-940Mbps speeds representative of that?
    I’m toying with the idea of this router for an 1000mbps FTTH connection.

    • I don’t have 1GB WAN connection. I believe most of us don’t have. Believe it or not. I am using 8MB ADSL here in Malaysia. That’s the best in my area. LOL =P

      Above result is LAN to LAN.

      • I see. Well it shouldn’t be much different I guess.
        (I imagined the port can be tested though using some other network device or PC, even without a gigabit internet service.)

  2. Up to how much storage can it support. I have 3TB external and hoping it would be supported. I can’t find anything about that storage support limit. Thanks!

  3. here the reading was at 100mbps, but the writing between 5 and 10mbps with a ssd in the usb
    Did you do what to get 40mbps of writing?

  4. Is it legal to import the Xiaomi 3G Wifi-Router to the EU and is it legal to operate it in the EU?
    While I am very happy with my Xiaomi 3G’s looks and price-performance-ratio, I am concerned about a number of legal issues which I have not seen beeing discussed in any review or product page info.
    The housing does not bear the CE-label, so my guess is that customs might not allow the import to the European Union, while still charging tax and possibly a fine.
    Even if the router passes customs one might get into deep trouble operating the router outside legal specifications.
    In Europe, Apple OS’s Wifi Analyzer complain about a misconfigured Wifi Router with Mainland-China-Region-Setting broadcasting nearby. So any one of your neighbours might find out that you are operation a Wifi router with Chinese-Region-Settings and might cause trouble.
    I have not been able to change the router’s region setting from Mainland China to Europe, even though the Mi Wifi App provides for region-settings.
    In 5GHz Band Xiaomi 3G also uses Channels above 147 which are not allowed in Europe as far as I know. And Channes 48 to 147 are only allowed if the router is able to uses Dynamic Frequency Selection (DFS) and I don’t know if the Xiaomi 3G is DFS enabled.
    Xiaomi 3G’s technical specification do not tell anything about signal strengt either. It is not transparent which of router’s 3 Signal-Strength-levels, if any, stays below a 100 mW or 200 mW signal strength.
    Flashing the Router’s OS I have not dared, since I have read some posts of technical skilled users turning the Xiaomi 3G into a brick.
    I would be happy to learn more dedails about the Xiaomi 3G Wifi.

  5. Hey there Jayce sir. There are these USB modems with 4G capability, you think i cannattach one of these sticks on the USB slot of the Xiaomi 3G to connect to the internet?

    Amazing review again btw =)
