First impression - Xiaomi Mi WiFi router 3G
What's in the box
As already the predecessor, the includes What's in the box only the router, Power Supplies with NEMA-1 connector (12V - 1.5A) as well as a Chinese Manual, If you want to use the included power supply in this country, you also need an EU adapter.
Design and workmanship
Xiaomi has the case of the 3. Xiaomi routers recycled, which is why the Xiaomi 3G router visually no bit different from its predecessor. The plain white case measures 19.5 cm in length, 13.10 cm in width and 2.40 cm in height. The total weight of the router is 261g. Wall mounting is not intended. Rather, the router is intended for placement, which is why it is also equipped with four tiltable omnidirectional antennas. All connections are placed on the back. There are also the reset button and the power connector. The front side has a multicolor status LED. The build quality is not objectionable.
Although the Xiaomi router 3G optically has not experienced any update, but has done much hardware instead. Xiaomi uses one MediaTek MT7621A System-on-Chip, whose dual-core MIPS1004Kc CPU clocks up to 880 MHz. This has not only increased the number of cores compared to its predecessor, which still relies on the MT7620N system-on-chip, the processor also clocks faster, allows faster storage connectivity, is USB 3.0 compatible and can support up to five gigabit Support Ethernet connections.
As a result, the Xiaomi Mi WiFi router 3G also in terms of storage facilities a good figure. Here, the router offers a 128MB SLC Nand Flash and one 256MB DDR3-1200 memory (Model 3 only with 128MB DDR2). The connection options amount to one WAN and two LAN ports with fast Gigabit connection and a USB 3.0 socket. The 4 omnidirectional antennas are used by both 2.4G and 5G WiFi. The are supported WiFi protocols IEEE 802.11a / b / g / n / ac, IEEE 802.3 / 3u / 3ab. The maximal Data transfer rate The Xiaomi Mi WiFi Router 3G specifies Xiaomi with 300 Mbps in 2.4G WiFi and 867 Mbps in 5G WiFi. Multi-User MIMO (MU-MIMO) is not supported.
The User Interface the router is based on OpenWRT and is by default only available in Chinese. This makes the commissioning initially complicated, but the device is overall uncomplicated and with the Google Translator without any problems. Once the router is set up, you can conveniently translate the user interface via the browser. Alternatively, it is also possible to flash firmware for Hong Kong and Taiwan, which is also available in English.
If you are familiar with the matter of firmware flash and have no problem with alternative software, you can even do that LEDE firmware, Prometheus or PandoraBox flash. These are open source projects, which are also based on OpenWRT and in terms of functions and possibilities leave a much greater latitude. Guides to the individual projects can be found on the net. For the review, the original firmware was left on the router.
Web interface and functions
As mentioned earlier, Xiaomi uses a custom OpenWRT. There are hardly any differences between the individual Xiaomi router models. Although all Xiaomi routers receive different firmware updates, the web interface is mostly identical visually and functionally.
Do you surf the Web interface of the Xiaomi WiFi Router 3G, you are greeted by a detailed overview that provides not only general router status information, but also connected device, throughput, and system utilization information. In the menu item to memory management explains how to connect an external medium to the router. Access from the computer is via the Mi WiFi client possible for both Windows and OSX. For mobile devices there is the so-called Mi WiFi App (Android and iOS), about which you can also set up a Samba server.
Within the general router settings can manage the WLANs. In addition to the typical configuration of the SSID, the password and the encryption, it is also possible to adjust the transmission power, as well as the WiFi channel can be freely selected. The 2.4G and 5G networks are configured separately. Interesting is the possibility to create a completely independent guest WLAN, which acts separately from the "main WLAN". Further settings are available for DHCP, the DNS and the white or blacklist.
In the subpoint of expanding settings can be configured QoS, DDNS can be added, port forwarding rules can be created, a PPTP or L2TP VPN can be preset and there are settings to UPnP.
Xiaomi Mi WiFi App
The Xiaomi Mi WiFi app is available for Android, as well as for iOS Mobile devices. In contrast to the standard Chinese web interface of the router, the app is also available in English.

Xiaomi Mi WiFi PC Client
The PC client is officially only available in Chinese. In contrast to the app and the web interface, the PC client mainly serves the simplified transmission of data. For example, you can start downloads that are made directly through the router and stored on the connected media. As an alternative to the HTTP or FTP download, it is also possible to use the Mi WiFi client to download torrents.
Practical test of the Xiaomi WiFi Router 3G
The Xiaomi router 3G was tested in the LAN with a Realtek 8111D network card and in WLAN with an Intel chip Wireless-AC 8260 module. The connected storage medium was a Toshiba STOR.E Basics USB 3.0 hard disk.
Signal strength WLAN
The built-up by the router WLAN convinces in both the 2.4 GHz, and 5 GHz network through constant signal at high range, Although the router in terms of data throughput is not quite the much more expensive Xiaomi R3P keep in mind, however, the Xiaomi router 3G shows above-average performance in view of the price. The transition between 2.4 GHz and 5 GHz is fluent.
NAS function and data throughput
In contrast to its predecessor, the Xiaomi router is 3G instead of with USB 2.0, with USB 3.0 fitted. The management of the connected storage medium via the Mi WiFi app. The File management The app is clearly arranged and the downloading and uploading works without any problems. If you have that Samba Server Plugin Activated via the app, you can also conveniently create a network drive via the PC and access the storage medium.
If you want to use the USB 3.0 function, it must be activated separately via the web interface or the app. At the same time, it should be noted that the USB 3.0 data transfers may interfere with the 2.4G WiFi. In the test, however, no differences or impairments were noticeable. Rather, the data throughput with active or deactivated USB 3.0 function was almost identical at least in the WLAN. Only in the LAN there was a noticeable speed difference with regard to the data transmission.
Transmission in the LAN
Transmission in the WLAN
The power consumption of the Xiaomi WiFi Router 3G is in the Idle at 8.2 Watt, at normal use will be values of 10.8 Watt reached. Is an additional one hard disk connected and accessed, the consumption increases 13 Watt at. It does not matter whether the USB 3.0 function is activated or deactivated.
