Neither router can be named the performance winner from the available evidence: there is no controlled, same-condition test of the ASUS RT-AX1800S against the Xiaomi Mi Router AX1800. Xiaomi publishes clear wireless and port specifications; for ASUS, check the exact model and revision, then compare local price, firmware and any mesh devices you plan to add.
ASUS RT-AX1800S vs Xiaomi AX1800: what the specifications establish
Both are Wi-Fi 6 routers in the AX1800 class. The Xiaomi figures below are manufacturer-stated theoretical link maxima, not independent test results or promised internet speeds.

| Specification | Xiaomi Mi Router AX1800 | ASUS RT-AX1800S |
|---|---|---|
| Wi-Fi bands and published rates | 2.4 GHz, 2×2 Wi-Fi 6: theoretical maximum 574 Mbps; 5 GHz, 2×2 Wi-Fi 6: theoretical maximum 1,201 Mbps. Xiaomi specifications | Not stated in the sources cited here; check the documentation for the exact model and revision. |
| Combined wireless figure | Theoretical dual-band total of 1,775 Mbps; Xiaomi says actual rate depends on the environment. This is not a single-client speed. Xiaomi product page | Not stated in the sources cited here. |
| Ethernet ports | One 10/100/1000M WAN port and three 10/100/1000M LAN ports. Xiaomi specifications | Port count is not established by the sources cited here; verify it in the documentation for your exact unit. |
| Other documented consideration | Mesh compatibility depends on generation and exact model pairing. Xiaomi mesh information | An independent review notes that the RT-AX1800S lacks DFS channel support. RTINGS review |
Why the advertised Mbps is not your internet speed
The Xiaomi’s band figures describe theoretical wireless link rates. They do not tell you what a phone or laptop will achieve, and the 1,775 Mbps combined figure should not be read as the speed available to one client. Actual results vary with the environment, client capability, distance, interference and internet connection. No matched throughput, range or latency results establish which router performs better.

Which AX1800 router should you buy?
Choose by the evidence you can verify locally
- Lean toward Xiaomi if its published port layout and specifications meet your needs. Confirm that the exact model sold in your market has the listed connections and that the seller’s price and support details suit you.
- Consider ASUS if its local price, exact hardware revision, firmware support and compatibility with your setup make it the better fit. The cited sources do not establish a general ASUS performance advantage.
- If you are choosing for a difficult layout, many clients or demanding stability needs, look for independent tests conducted in a home and with client devices similar to yours. The specifications alone cannot settle those questions.
There is no current, region-specific price or stock comparison established here, so compare listings for the same exact model in your market rather than relying on a universal price verdict.

Check the ASUS model revision before updating firmware
ASUS distinguishes the RT-AX1800S from the RT-AX1800S V2, and their firmware tracks are separate. Its support page lists V2 firmware 3.0.0.4.388_34163 dated 2026-09-29 and states that this release applies only to V2; the page also provides separate firmware for the non-V2 model. Check ASUS firmware and model details.
- Read the model label on the router and confirm whether it says RT-AX1800S or RT-AX1800S V2.
- Open the ASUS support page for that exact revision and select its matching firmware track.
- Check the release notes and model applicability before installing; do not apply a V2 file to the non-V2 unit or vice versa.
Firmware availability can change. This cited release detail is specific to the listing dated 2026-09-29 and does not establish the current security-support lifecycle for every region.

Does Xiaomi AX1800 support mesh?
Xiaomi identifies the Mi Router AX1800 as part of its first-generation mesh architecture. It says this router cannot create a mesh network with the Xiaomi Wi-Fi Range Extender AX1500, which uses a newer generation. Xiaomi’s mesh compatibility information.

Placement and channel considerations
Start with sensible router placement
ASUS’s quick-start guide recommends placing the router centrally and using the supplied power adapter. These are setup recommendations, not evidence of a guaranteed coverage radius. ASUS quick-start guide.
Account for DFS channel support
RTINGS notes that the RT-AX1800S lacks DFS channel support. That is a specific limitation reported for the ASUS model in its review; it does not prove that Xiaomi is faster or better. If DFS support matters for your wireless environment, verify the exact router’s supported channels and local regulatory rules before choosing.

What this comparison cannot determine
The available specifications and model-specific notes do not establish a controlled winner for range, throughput or latency, nor do they provide current local prices, stock or Xiaomi firmware and security lifecycle details by region. Treat those as questions to verify for your market and setup, rather than assuming the AX1800 label answers them.
