Xiaomi Mi Router AX1800 RA67 (review)


In reviewing the Xiaomi Mi Router AX1800 RA67, I had to ask why people bother to buy Wi-Fi 5 AC routers anymore? Why? Because it is Wi-Fi 6 AX1800 and at $99.95 has very good performance.

To put the Xiaomi Mi Router AX1800 RA67 in perspective, it is what financially challenged folk buy. And they know a bargain. Because at $99.95, it does everything a small apartment dweller could want. You can later buy the AX3600 and use this as a mesh satellite (see our Xiaomi AIoT AX3600 review here 9.6/10).

Details: Xiaomi Mi Router AX1800 RA67 White (global model)

  • Website here and from PC Byte as well here
  • Price: $99.95
  • Xiaomi is better known for its smartphones, where it has been a global top-5 player for some time. The brand is gaining a strong foothold in Australia via Panmi as its authorised Australian distributor.

Note: Xiaomi makes a huge range of models for different markets due to different Wi-Fi spectrum allocations and government requirements. If you are looking for other reviews, search for Xiaomi RA67.

First impression

Looks wise, it’s a pretty typical white rectangular box router with four external antennae. In terms of type, it’s an AX1800 router – made up of 2.4Ghz (574Mbps) and 5Ghz (1201Gbps). What sets it apart is a four-antenna system (unusual at this price) which supports two transmit, and two receive MU-MIMO streams. Without getting too techy, that means good throughput for a mix of 2.4Ghz and 5Ghz devices.

The 5Ghz also has OFDM and 64/256/1024QAM, which means it can aggregate spare bandwidth up to 1200Gbps. And let me tell you, it did not disappoint. At 2m from the router, the Surface Pro 7 connected at 1.2Gbps and at 5M was 721Mbps – that shows a good, strong antenna design.

Setup – perhaps the easiest I have used

  • Plug it into the Aussie Broadband Gateway via its WAN port (LAN port 4)
  • Power-up with 12V/1A Australian plug charger
  • Go to a PC and log into the Xiaomi network (no internet and no passwords at this stage)
  • Setup via in a web-browser. We could not get the Mi Home app to work.
  • It mandates new passwords for the Wi-Fi and Admin, and that is it.

Inside the router firmware

MiWiFi is a clean, simple interface, and you don’t need to change any default settings. But if you don’t have AX devices like the Samsung S21 or Microsoft Surface Pro 7, then turn off AX support as it introduces an AC compatibility mode. And it has all the usual Open WRT operating system smarts like IPv6, MAC Address clone, DHCP/DDNS/Static IP, VPN QoS, and UPnP (disabled by default). You can change LAN IP settings, although I prefer that it uses instead of the usual – especially if you want to swap out existing networks.


There are three dedicated gigabit LAN ports and one WAN port.

Tests using a Samsung S20 Ultra 5G

Speeds are MBps and -dBm signal strength

These specs are very good for this price, especially 5Ghz to 15m (and it could have gone a couple of more metres). This should cover a 15meter diameter circle or about 170m2 quite well.

GadgetGuy’s take

Using a Qualcomm IPQ 6000 processor, four independent antenna amps, and WRT open-source software (wrapped in MiWi-FI skin), it is a great router. Antenna strength is excellent. Xiaomi says that in theory it can service 128 devices. We think 10-15 on 2.4Ghz is more realistic.

If you can place this in the home’s dead centre, it will give you excellent performance. Readers ask about privacy. My take is that we have investigated using Fing Box, Trend Micro Home Security and Nortons 360, and we cannot find any data exfiltration. We think Xiaomi is a pretty safe bet. We think Xiaomi is a pretty safe, terrific value bet. You can read other GadgetGuy Xiaomi news and reviews here and viomi reviews here.
