How to accurately measure the speed of the Internet on the Xiaomi router: from built-in tools to professional tests

The speed of the Internet through the Xiaomi router often becomes a bottleneck even at the tariff with the declared 1 Gbps The problem is not always in the provider: the fault may be the settings of Wi-Fi, congestion of the channel by neighboring networks or hardware limitations of the model (for example, Mi Router 4A does not support Wi-Fi 6). To separate real problems from myths, you need to correctly measure the speed – not only on the smartphone, but also directly on the router.

In this article you will find unique testing methods that even technical support specialists will not show: from the hidden functions of the Xiaomi web interface to bypassing the provider’s restrictions using the help of the service provider. VLAN-We'll look at why cable speeds and air speeds are different. 2–3 How does the channel width affect the result? 20/40/80 Why Speedtest on the phone is lying to you 30–50%.

Why Standard Speed Tests Lie: 3 Hidden Reasons

Most users measure speed through applications like Speedtest or Yandex.Internetometrist, and they get deliberately underrated results.

• 📱 Client device limitations: Even Xiaomi’s flagship 14 Ultra smartphone won’t be able to show more than 500-600 Mbps over Wi-Fi 6 because of the chip’s hardware limits. AX200 They can stretch up to 900 Mbps, and old phones can only reach 150-200 Mbps.
• 🌐 Servers for tests. Speedtest automatically selects the nearest server, but it can be overloaded or on another network (for example, MTS, when you are connected to Rostelecom%.
• 🔄 Overload router. If on Xiaomi AX3600 work together IPTV, Torrent and Smart TV, The test will show the speed, taking into account all the loads, and the real "clean" speed can be 1.5-2 times higher.

Another catch: ISPs often specify the speed of access to their network (for example, 300 Mbps), but the real rate of revenue to the global Internet is limited by peering agreements with other carriers. For example, when you download a file from a Mail.ru server, you can only get 150 Mbps, although Speedtest will show 280 Mbps.

Method 1: Built-in speed test in Xiaomi web interface

All Xiaomi routers (starting with MiWiFi firmware) R3600 and newer) have a hidden tool to check the speed directly through the WAN-This is the most accurate method, because it eliminates the impact of Wi-Fi and client devices.

To take advantage of it:

1. Connect your computer to the router via cable (LAN-port).
2. Open your browser and type 192.168.31.1 (or miwifi.com).
3. Log in (the username and password by default is usually a combination with a sticker on the bottom of the router).
4. Go to the Status → Network Map section (on new firmware, the path may differ: Additional → Diagnostics → Speed Test).
5. Click Start Test. The system automatically picks up the server and measures the real speed. WAN-port.

⚠️ Note: If the router is connected via PPPoE (with login/password authorization), the test can show a speed below real by 10-20% due to the protocol overhead).

Disconnect all devices from Wi-Fi except for test PC|

Method 2: Checking with Mi Home/Wi-Fi

The official Mi Home app (or Xiaomi Wi-Fi for older models) allows you to check the speed of the Internet, but with reservations:

• 📊 The test is conducted through Xiaomi’s cloud, so results may depend on server loads in China.
• 📶 Speed is measured over Wi-Fi, not cable, which adds to the error.
• 🔄 The app does not show ping and jitter – critical settings for online games and video calls.

Instructions:

1. Open Mi Home, select your router.
2. Go to Settings. → Internet speed.
3. Press the Speed Test. The app will show download, recoil and delay.

🔹 Tip: If the speed in the application is much lower than on the cable, try it:

• 🔄 Switch the Wi-Fi channel manually (e.g., from car to channel 36 in the 5 GHz band).
• 📶 Disable Band Steering (automatic switching between 2.4 GHz and 5 GHz).
• 🔌 Connect to the router via cable and repeat the test.

Method 3: Direct connection to the provider (bypass router)

If you suspect that the problem is in the router itself, you can connect your computer directly to the provider's cable, bypassing Xiaomi.

1. Disconnect the provider's cable from WAN-router-port.
2. Connect it directly to the Ethernet port of your PC or laptop.
3. If the provider uses PPPoE, set up the connection manually: Control Panel → Network and Internet → Network Management Center → Creating a new connection → Internet Connection → High-speed (PPPoE) Enter the login / password from the contract with the provider.
4. Run the speed test on Speedtest.net or Yandex.Internetometer.

⚠️ Note: If the direct connection speed is higher than through the router, the problem lies in the:

💡

If the provider uses a binding MAC-Address, before connecting the PC to the cable, clone MAC-router address in network card settings (in Device Manager) → Adapter properties → Additionally. → Network Address).

Method 4: Professional tools (iPerf3, WinMTR)

For a deep diagnosis, use iPerf3, a utility that measures real network bandwidth without the limitations of browser tests, which will show whether your Xiaomi router is able to “pump” the claimed 1 Gbps.

Instructions for Windows/Linux:

1. Download iPerf3 from the official website: iperf.fr.
2. Install on two devices: one will be a server (for example, a PC connected via cable), the other - a client (laptop over Wi-Fi).
3. Start the command on the server: iperf3-s
4. On the client, do it: iperf3 -c [IP-server address] -t 30 -P 10 where -t 30 — test-time (30 seconds), -P 10 — 10 parallel flow for loading.

The results of iPerf3 are interpreted as follows:

• 📈 [ID] Interval Transfer Bandwidth – Real Data Transfer Speed.
• 🔄 Sender/Receiver — If the values are very different, the problem is in the duplex (try replacing the cable).
• 🛑 Retr is the number of retransmissions of packets. > 1%, there is interference on the network.

To check the stability of the connection, use WinMTR (analogue of traceroute with packet loss statistics). Run a test on 100 packets to ya.ru or google.com. If the loss is > 1%, contact your provider.

💡

iPerf3 shows the maximum speed your network can provide, while Speedtest is limited by the speed of access to the test server.

Method 5: Alternative online services (IPv6)

If your ISP supports IPv6, standard tests like Speedtest may not show real speed.

• 🌍 Test IPv6 — Checks the speed and correctness of the setting IPv6.
• 📡 Fast.com (from Netflix) – streaming optimized, shows speed without caching.
• 🔍 DSLReports – detailed analysis with ping and buffer graphs.

🔹 How to choose a service?

If you care:

• 🎮 Game stability - watch ping and jitter in DSLReports.
• 📺 Streaming Quality – Use Fast.com (it simulates video downloads).
• 🔧 Diagnostics IPv6 — only test IPv6.

Frequent Speed Checking Mistakes and How to Avoid Them

Even experienced users make mistakes that distort test results, and here are the most common:

1. 📱 Testing on a weak device. Smartphone Redmi Note 10 with Wi-Fi 5 will not show more than 300 Mbps, even if the router produces 1 Gbps. Use PC with Ethernet or Wi-Fi 6.
2. 🌐 In Speedtest, manually select your provider’s server (e.g., Rostelecom) → Moscow).
3. 🔌 Using a damaged cable. Cat.5 It will not pull 1 Gbps - you need Cat.5e Call the cable with a tester or replace it with a knowing worker.
4. 🕒 Rush hour testing: In the evening (18:00-23:00) speeds can drop by 30-50% due to the loading of the provider’s network.

⚠️ Attention: If you are using VPN, Turn it off before the test. NordVPN or ProtonVPN servers can limit speeds to 100-200 Mbps even at a 1 Gbps rate.
