How to change the Wi-Fi channel on your Xiaomi phone: the complete guide

Weak Wi-Fi signal on your Xiaomi or Redmi? Constant connection breaks, low download speeds, although the router is nearby? The reason may lie in the wrong Wi-Fi channel. In urban environments where dozens of networks operate at the same frequencies, automatic channel selection is often mistaken. In this article, you will learn how to manually change the Wi-Fi channel on Xiaomi phones, why it is important, and which channels are best used for maximum stability.

It's important to understand that a Xiaomi smartphone can't directly change the router's channel, it just connects to the network you're on. But you can analyze the loading of the channels through the phone and then set the router up optimally. We'll look at both scenarios: how to check the current channel on Xiaomi and how to change it on the router (including Xiaomi Mi Router models), and you'll learn which channels are less crowded in apartment buildings and how to avoid interference from neighbors.

Why you should change your Wi-Fi channel to Xiaomi

By default, most routers (including Xiaomi Mi Router, Redmi Router and TP-Link models) use automatic channel selection. This is convenient, but not always effective. In apartment buildings on one channel (for example, 6th or 11th) can run up to 10-15 networks at a time, the result is overload of air, which manifests itself as follows:

• 📶 Wi-Fi signal is available, but pages load very slowly
• 🎮 Lags appear in online games, although the speed on tests is high
• 📺 Video in the video 4K Permission is constantly “hanging” or decreasing
• 🔄 When connected to the network, the phone gets a long time IP-address»

The problem is compounded by the fact that 2.4 GHz channels (the most common) overlap each other. For example, if the neighbor router runs on channel 6 and yours runs on channel 7, they will interfere with each other. The solution is simple: choose the least loaded channel in your range. At 5 GHz, there are fewer such problems, but there are nuances there too (we will discuss this below).

Xiaomi phones (including POCO, Black Shark) don't have a direct option to change Wi-Fi channel because the router sets the channel, but the smartphone can show the current congestion so you can choose the best option to set up your router.

How to check the load of Wi-Fi channels on Xiaomi

Before you change your channel on your router, you need to understand which channels are free in your environment, and for that, Xiaomi has built-in tools, but they're hidden in the engineering menu, and you can also use third-party apps, which are simpler and more visual.

Method 1: Using WiFi Analyzer

The easiest way is to install the free WiFi Analyzer app (available on Google Play), which shows all the networks around you and how they are distributed across channels.

1. Download and install WiFi Analyzer.
2. Open the app and go to the Channel Graph tab.
3. Look at which channels (from 1 to 13 for 2.4 GHz) are less loaded. The optimal choice is to choose channels 1, 6 or 11 - they do not overlap.
4. For 5GHz, see the ranges 36-48 (lower) or 149-165 (upper).

Example: if channel 6 has 5 networks and channel 1 only 1, it is better to choose the first one.

Method 2: Through the Engineering Menu (without root)

Xiaomi phones have a hidden engineering menu where you can see information about the current connection, including the channel.

1. Open the phone app and enter the combination: ##4636##
2. In the menu that opens, select Wi-Fi Information.
3. Look at the Wi-Fi frequency bar, where the current channel will be specified (e.g. 2437 means a 6 channel at 2.4 GHz).

⚠️ Warning: Do not change other settings in the engineering menu unless you are sure of their purpose.

💡

If the engineering menu doesn’t have channel data, try connecting to another network or restarting your phone.

How to change the Wi-Fi channel on the Xiaomi router

Now that you know which channel is less crowded, you need to configure the router. If you have a Xiaomi Mi Router (any model: Mi Router 4A, Mi Router AX3600, Redmi Router AC2100, etc.), you can do this through the Mi Wi-Fi mobile application or web interface.

Configure via the Mi Wi-Fi app

1. Open the Mi Wi-Fi app (you can download it here).
2. Go to the Wi-Fi settings section → Additional settings.
3. Select a range (2.4 GHz or 5 GHz).
4. Click on the Channel field and select the best option from the list (e.g. 1, 6 or 11 for 2.4 GHz).
5. Save the settings and restart the router.

For 5 GHz, choose channels from the bands:

• 🔹 36-48 — Lower range (better for walls)
• 🔹 149-165 — upper range (less interference, but worse passes through obstacles)

Configure via web interface

If the application is not working or you have a different router model (for example, TP-Link), use the browser:

1. Connect to the router network.
2. Enter 192.168.31.1 (for Xiaomi) or 192.168.0.1 (for other brands) in the browser address bar.
3. Sign in (the username and password is usually admin).
4. Go to the Wi-Fi section → Wireless network settings.
5. Select the channel manually and save the changes.

⚠️ Attention: After changing the channel, all devices will be disconnected from the network and must connect again. If the speed has not improved after the change, try another channel through the network. 1-2 The day (network load may change).

The Best Wi-Fi Channels for Xiaomi in 2026

Not all channels are equally good. The 2.4GHz band (the most common) has a rule: channels 1, 6 and 11 don't overlap, which means that if you choose one and neighbors choose the others, there will be minimal interference.

For 5 The situation is more complicated: there are more channels (up to GHz). 165), But not all of them are supported by all devices, like older smartphones, you might not see the channels above. 144. Channels are also banned in Russia. 120-128 (used for radar systems).

Critical information: Xiaomi routers often turn on Auto mode for 5 GHz by default, which selects channels from the lower range (36-48). If you have many neighbors with the same routers, manually switch to the upper range (149-165) - there is usually freer.

Frequent errors when changing Wi-Fi channel

Even after the channel change, Wi-Fi problems may remain, and here are the typical mistakes Xiaomi users make:

• 🔄 The router has not restarted after changing the settings.
• 📱 You didn't update the router's firmware. Older versions of the software may have bugs with manual channel settings.
• 🌐 We chose a channel that doesn't support the phone, for example, some models. POCO Do not work with 5 GHz channels above 144.
• 📡 Ignored the neighboring networks on the same channel. Even if you chose channel 1, but it has 3 other networks, interference will remain.

Another common problem is that the router automatically returns to its previous settings, which happens if:

• 🔌 Smart Connect mode enabled (combining 2.4 and 5 GHz into one network).
• 🔄 In the settings of the router is a tick Automatic channel selection.
• 📱 The router firmware dropped to factory settings (occasionally after the lights out).

To avoid these problems, after changing the channel:

1. Turn off Smart Connect in the router settings (if any).
2. Make sure the channel mode is Manual.
3. Check that the router firmware is updated (the Mi Wi-Fi app has a corresponding section).

💡

If the speed has not improved after changing the channel, check the load again after 1-2 days. Neighbors can also change the settings of their routers.

Additional settings for stable Wi-Fi on Xiaomi

If you have any problems with Wi-Fi, check these parameters:

Channel Width (Channel Width)

For 2.4 GHz, it's better to set 20 MHz, which reduces speed but increases stability. 40 MHz width gives you higher speed, but is more prone to interference.

For 5GHz, you can use 40MHz or 80MHz (if the router and phone support).

2. Wi-Fi (Mode) standard

In the router settings, select:

• 🔹 802.11 b/g/n for 2.4 GHz (maximum compatibility)
• 🔹 802.11 a/n/ac/ax for 5 GHz (if the phone supports Wi-Fi) 6)

Transmit Power (Transmit Power) 3

If the router is far from the phone, increase the signal power (Transmit Power or Tx Power option).

4. DFS mode (for 5 GHz)

52-144 channels in the 5GHz band require support for Dynamic Frequency Selection (DFS). If your router and phone support this mode, you can use these channels — they are usually freer. But be prepared for the fact that the router can automatically change the channel if you detect radar interference.

On Xiaomi phones with Wi-Fi 6 support (e.g. Xiaomi 13, POCO F5), you can turn on 802.11ax mode to improve speed and reduce latency.

1. Go to Settings. → Wi-Fi.
2. Click on your network name and select Additional settings.
3. Enable the Wi-Fi 6 option (if available).
