Why Change Your Wi-Fi Channel on Xiaomi Router and When to Change It
Did you notice that the Internet on Xiaomi Mi Router has become “slow” even though the speed on the cable has remained the same? Or YouTube videos are constantly “hanging” and online games are being laid? The reason may lie in an overloaded Wi-Fi channel. In apartment buildings, neighbors routers often work at the same frequencies, creating interference. Changing the channel is an easy way to restore stability without buying new equipment.
But don't be in a hurry to change the settings at random! 80% of the time, the problem is not the channel, but the wrong choice of range (2.4 GHz vs 5 GHz), outdated firmware or weak signal. In this article, we will discuss how to check the load of channels, which to choose for maximum speed, and give a step-by-step instruction for all Xiaomi models – from the budget Mi Router 4A to the flagship AX9000.
⚠️ Important: If your router supports Wi-Fi 6 (models) AX1800, AX3000 Change of channel may require additional settings in the section OFDMA. About this in a separate section below.
How to know if your Wi-Fi channel is overloaded
Before you go into your router settings, check if it makes sense to change the channel. Here are 3 signs that interference is the problem:
- 📉 Wi-Fi speed is 2-3 times lower than cable speed (check at Speedtest).
- 🔄 Video in the video 4K or online broadcasts are "breaking", although the Internet cable is connected to 100+ Mbit/s.
- 📡 The list of available networks (on the phone or laptop) is displayed 10+ the same name (for example, the same name, «Xiaomi_XXXX»).
For accurate diagnosis, use special utilities:
| Programme | Platform | What shows |
|---|---|---|
| Wi-Fi Analyzer (inSSIDer) | Windows, macOS | Real-time channel load, neighbor signal level |
| WiFi Analyzer (VREM Software) | Android | Timetable of channel employment, recommendations for choosing free channels |
| WiFi SweetSpots | iOS | Best channels for 2.4 GHz and 5 GHz, signal strength |
🔹 Advice: If you have Xiaomi Mi Router 4C Or another model without 5GHz support, look at the channels 1, 6 and 11, they don't overlap. In the 5GHz band, choose the channels from the channel. UNII-1 (36-48) for minimal interference.
Step-by-step: how to change the channel on the router Xiaomi
The process is the same for most models, but there are nuances for the firmware MiWiFi (Chinese version) and Padavan (castom).
Method 1: Using the Mi Wi-Fi mobile application
Step 1. Open the Mi Wi-Fi app and connect to the router. If it's not on the device list, click Add Device → Router.
Step 2. Go to the Wi-Fi settings section (the gear icon next to the network name).
Step 3. Select the range:
- 📶 2.4G Wi-Fi for older devices (smartphones until 2018, smart appliances).
- 🚀 5G Wi-Fi - for modern gadgets (supports speeds up to 1 Gbps).
Step 4: Click the Channel and select the value from the list. 2.4 GHz is optimal for 1, 6 or 11; 5 GHz is optimal for 36, 40, 44, 48.
Step 5: Save settings and restart the router (Reset button in the main menu).

Method 2: Through a Web Interface (192.168.31.1)
If the app doesn’t work or you prefer a computer:
- Open your browser and type 192.168.31.1 (or miwifi.com).
- Log in (the default login and password is often admin + password from the sticker on the router).
- Go to Settings. → Wi-Fi.
- In the Basic Settings block, find the Channel field and select the value from the drop-down list.
- Click Save and wait for the reboot (1-2 minutes).
⚠️ Note: On routers with Padavan firmware (for example, after flashing), the path will be different: Additional settings → Wireless network → You can also turn on Autochannel Selection, but it doesn't always work correctly.
What if there is no channel on the list?
Which channel to choose for maximum speed: model recommendations
There is no universal “best” channel, depending on the load in your region and the standards supported. Below is a table of optimal values for popular Xiaomi routers:
| Model router | 2.4 GHz (best choice) | 5 GHz (recommended channels) | Notes |
|---|---|---|---|
| Mi Router 4A/4C | 1, 6, 11 | — | No support for 5GHz. Avoid channel 13 - it may not work on some devices. |
| AX1800/AX3000 | 6 (if free) | 36, 40, 44 | Supports Wi-Fi 6. Enable 160 MHz for maximum speed (in Additional Wi-Fi settings). |
| AX6000/AX9000 | 11 (less loaded) | 48, 149, 153 | For gaming PCs, choose channels 149-165 (less interference but shorter range). |
| Mi Router 3/3G/3Pro | 1 or 11 | 36–48 (if there is 5GHz) | On old firmware may not be a manual choice – update the software! |
A critical nuance for Wi-Fi 6: If your router supports AX-standard (models) AX1800 If you manually select a channel, turn off the automatic channel width option and set a fixed value of 80 MHz or 160 MHz.
💡
If you live in a private home or on the top floor of an apartment, try channels 12 and 13 in the 2.4 GHz band - they are less used, but can give a better signal in open areas.
Frequent Channel Change Mistakes and How to Avoid Them
Even experienced users sometimes make things worse by choosing the wrong settings. TOP-5 mistakes and their solutions:
- Select an overlap channel. In the 2.4 GHz range, channels 1-14 intersect. For example, if a neighbor uses 3 and you choose 4, interference will remain. Solution: Choose only 1, 6 or 11.
- Ignoring channel width: 40 MHz width at 2.4 GHz can interfere with other devices.Solution: Set 20 MHz for 2.4 GHz and 80 MHz for 5 GHz.
- Device incompatibility: Some gadgets (e.g., Yeelight smart bulbs) only work on channels 1 to 11. Solution: Check device requirements before changing.
- Forgot to restart the router. The changes only take effect after the reboot. Solution: Press Reboot in the settings or turn off the power for 30 seconds.
- Auto-channel selection in jammed environments. Auto often selects the busiest channel. Solution: Turn it off and select the channel manually.
⚠️ Warning: If the speed has dropped after changing the channel, check if the router is running Repeater Mode (WDS). The channel must be the same as the main router!
💡
Before changing the channel, always check the load in real time – even the “recommended” channels can be occupied in your home.
Additional settings for advanced users
If the standard channel change didn’t help, try these hidden options (not available on all models):
- 🔧 Wireless Mode: Select Wi-Fi settings 802.11n/ac/ax It's going to cut off old devices, but it's going to speed up the speed of modern devices.
- 📡 Tx Power: On Padavan models, you can increase power to 20 dBm (17 dBm by default!
- 🔄 Beamforming: Include this option in Additional Wi-Fi settings – it focuses the signal on connected devices.
- 🛡️ Interference Mitigation (Interference Mitigation): AX6000 and AX9000 optional BSS Coloring (in Wi-Fi Settings 6) It reduces the impact of neighbors.
🔹 For owners of Xiaomi Mi Router 4Q: There's a bug in this model, and when you change the channel, the Internet can disappear. IPv6 In Settings → Internet.
