Mixed Network Mode on Xiaomi: How to Enable and Configure for Stable Wi-Fi

Mixed network mode (or dual Wi-Fi band) on Xiaomi devices allows you to automatically switch between the 2.4 GHz and 5 GHz bands without breaking the connection. This feature is especially useful if you have devices that support only 2.4 GHz (for example, smart light bulbs or old smartphones), and others run faster at 5 GHz (laptops, modern phones). Without mixed mode, you have to create two separate networks, which complicates management and reduces convenience.

In this article, we will discuss how to enable mixed mode on Xiaomi smartphones (as an access point), Xiaomi Mi Router routers and Mi TVs. Also explain why sometimes the feature may not work, and how to fix typical errors. If you notice that devices are “lost” between networks or speed drops when switching, this guide will help you set things up correctly.

What is a mixed network mode and why it is needed

Mixed mode (or Smart Connect in Xiaomi routers) is a technology that combines two Wi-Fi networks (2.4 GHz and 5 GHz) under a single name (SSID).

• 📱 Close to the router – priority 5 GHz (high speed, but shorter range).
• 🏠 At a distance – automatic switching at 2.4 GHz (better passes through walls).
• 🔄 Smooth transition – without breaking the connection when moving around the house.

Without this feature, you would have to manually select a network (e.g., you would have to choose your network, Mi_Home_2.4G and Mi_Home_5G), It's very inconvenient:

• 🎮 Game consoles (PlayStation, Xbox), which often "stick" in the slow range.
• 🖥️ Laptops with Wi-Fi 6 support that need top speed.
• 💡 Smart devices (Yeelight, Roborock) running only 2.4 GHz.

⚠️ Note: Some Xiaomi models (e.g. Mi Router) 4A) Mixed mode is disabled by default, and activation of this mode can reduce connection stability for older devices that do not support fast roaming (802.11k/v).

How to enable mixed mode on the Xiaomi router

The instructions are suitable for most models: Mi Router 4/4A/4C, Mi AIoT Router AX3600, Redmi Router AX5 and others. Before setting up, make sure that the router firmware is updated to the latest version (check in Settings → Update).

Steps for activation:

1. Open the Mi Wi-Fi app (or Xiaomi Router for new models).
2. Go to Settings → Wi-Fi → Additional settings.
3. Find the Mixed Mode (or Smart Connect) option and turn it on.
4. Set the same network name (SSID) and password for both bands (if they differed previously).
5. Save the settings and restart the router.

Make sure the router is connected to the Internet |

Update the firmware to the latest version|

Remember your current Wi-Fi settings (SSID and password)|

Disable the guest network (if it is active)|

Check if your model supports Smart Connect (list below)

If the Smart Connect option is not on the menu, your router doesn't support it, and here's a list of models with confirmed support:

💡

If some devices stop connecting after the mixed mode is turned on, try temporarily disconnecting it and connecting to the 2.4 GHz network manually, which often solves the problem for older gadgets.

Mixed mode setting on Xiaomi smartphone (access point)

If you use a Xiaomi smartphone (e.g. Redmi Note 12, POCO X5, Mi 11) as an access point, then mixed mode works differently here. By default, the phone only creates a network at 2.4 GHz, but you can be forced to turn on 5 GHz or combined mode through hidden settings.

Instructions for MIUI 14 and newer:

1. Open Settings → Mobile Network → Modem Modem.
2. Activate the Wi-Fi Access Point.
3. Press the Access Point Settings.
4. In the Frequency Range field, select Auto (2.4/5 GHz).
5. Set a password (minimum 8 characters) and save it.

If you do not have an auto option, use the engineering menu:

Enter the phone code in the app: ##4636##


Go to "Wi-Fi Information" → "Wi-Fi settings"




Find the Wi-Fi frequency band and select Auto.

⚠️ Attention: On some firmware MIUI For the Global versions, the engineering menu can be blocked, in which case only the flashing on the EU-rum ADB-team.

Mixed regime problems and solutions

Even after you set it up properly, you can have failures, and here are the typical problems and ways to fix them:

• 🔄 Devices do not switch between ranges Check if your router supports 802.11k/v (If not, mixed mode will work worse. Solution: update the firmware or turn off the feature.
• 📶 Weak signal at 5 GHz Reduce the transmission power in the router settings (Tx Power option). or move the router closer to the center of the room.
• 🔒 Some devices do not connect Temporarily turn off WPA3 In the security settings (save only) WPA2-PSK).
• ⚡ Speed drops when you switch. This is normal for low-cost routers. Solution: lock the device into one bandwidth through its Wi-Fi settings.

Critical error: If the router starts cyclically restarting after switching on the mixed mode, reset it to factory settings (Reset button for 10 seconds) and repeat the setting without activating Smart Connect.

Mixed mode on Mi TV and Mi Box

Xiaomi Mi TVs TV 4/5 And the Mi Box S also supports interconnection, but there's a nuance here. 5 GHz for maximum speed (important for the 4K-content), but if the signal is weak, it can stick to a slow range.

How to set up:

1. Open Settings → Network and Internet → Wi-Fi.
2. Choose your network (if it is one, it is a mixed mode).
3. Click on Additional Settings.
4. Enable the option Automatic range selection (or turn it off for manual selection).

If the TV doesn't see the 5GHz network:

• 🔍 Check if your model supports 5GHz (e.g. Mi). TV 4A It only works at 2.4 GHz).
• 📡 Make sure that the router is on mode. 802.11a/n/ac (for 5 GHz).
• 🔄 Restart the TV and router.

How to check if the mixed mode works

To make sure that devices switch between ranges correctly, follow the following steps:

1. On the router: Go to Settings → Connected devices. See which network (2.4G or 5G) each device is on.
2. On your smartphone/laptop: Use the Wi-Fi Analyzer (Android) or NetSpot (Windows/macOS) app. Check which range the device is currently connected to.

Speed test:

• Take a speed measurement next to the router (should be 5 GHz).
• Move to another room and repeat the test (should switch to 2.4GHz automatically).

If the switching does not occur:

• 🔧 Check if the Smart Connect is enabled on the router.
• 📱 Update the firmware on connected devices (especially on Android smartphones).
• 🔄 Manually “forget” the network on the device and connect again.

💡

Mixed mode does not increase Internet speed, but only optimizes the connection of devices to the most suitable range. If your tariff is limited (for example, 100 Mbps), then even at 5 GHz you will not get more than this speed.

Alternatives to mixed treatment

If your router does not support Smart Connect, or the feature is unstable, consider alternative solutions:

• 🔗 Mesh systems (Xiaomi Mi Mesh): automatically switch devices between nodes without breaking the connection.
• 📡 Two separate networks: Create Mi_Home_2.4G and Mi_Home_5G with different passwords and connect devices manually.
• 🔄 By binding MAC: In the router settings, fix certain devices on the desired range.
• 🛠️ Firmware from third-party developers (such as OpenWRT): adds support 802.11k/v on unofficially supported models.

For owners of Xiaomi Mi Router 3G/3C, where there is no mixed mode, the best option is to purchase a newer model (for example, Redmi Router AX5) or use a repeater to expand the 2.4 GHz network.
