Shutdown IPv6 On Xiaomi devices: all the ways and nuances

Protocol IPv6 As it becomes more common, many Xiaomi users still face the need to disable it, and the reasons can range from problems connecting to certain sites to conflicts with the local network or corporate security policies. In this article, we will discuss how to completely or selectively deactivate. IPv6 on various devices of the brand – from smartphones to routers.

It is important to understand that the disconnection IPv6 It doesn't always solve network problems. In some cases, errors are associated with the protocol incorrectly, whereas the real reason lies in the settings. DNS, MTU Before you make any changes, make sure your ISP does support dual-stack. IPv4 and IPv6) and does not block traffic through IPv4.

If you are using a device based on MIUI 14 or new HyperOS, the shutdown algorithm may differ from the older versions of firmware, the same applies to Xiaomi Mi Router or Redmi Router routers – their web interfaces are updated regularly, and the location of options changes. We’ve taken into account all the current changes for 2026 and collected universal methods that work on most devices.

Why you might need to disconnect IPv6 Xiaomi

Despite the fact that IPv6 It's considered the future of the Internet, but it's not always perfect, and here are the most common scenarios where Xiaomi users decide to deactivate the protocol:

• 🌐 Problems with access to websites: some resources (especially banking or government) may not work properly through the Internet. IPv6, misstep ERR_CONNECTION_REFUSED or DNS_PROBE_FINISHED_NXDOMAIN.
• 🏢 Corporate networks: offices often use only IPv4, and on IPv6 It can create conflicts with VPN proxy.
• 📶 Mobile Internet: Some operators (for example, Tele2 or Yota) IPv6 is unstable, which leads to breaks in the connection.
• 🖥️ Local area networks: if your home network has devices (such as printers or other devices) NAS), supportive IPv6, Their detection may be difficult.
• 🛡️ Security: Some users prefer to disable IPv6 Potential vulnerabilities (e.g. attacks by ICMPv6).

Before you turn off the protocol, check if it's really the problem. IPv6 You can use the settings of your router or your smartphone to test the network, and if you don't improve, it's something else.

How to turn off IPv6 on a Xiaomi smartphone (MIUI/HyperOS)

On Xiaomi smartphones disconnect IPv6 It depends on the firmware version. MIUI 12-14 And the new HyperOS algorithm is similar, but there are nuances.

For MIUI 12/13/14:

1. Open the Settings. → Wi-Fi.
2. Click on your network name (or icon) ⚙️ near).
3. Select additional settings (or IP-setting).
4. In the section IP-version (or Protocol) IP) choose IPv4.
5. Save the changes and reconnect to the network.

For HyperOS:

1. Go to Settings → Connections and Sharing → Wi-Fi.
2. Tap on the network name. → Change the network.
3. Scroll down to Advanced Settings → Settings IP.
4. Just set the value. IPv4.
5. Confirm the change.

If only option IPv4 missing, which means your firmware version does not support manual shutdown IPv6. Alternative methods may be used (see the following section).

Check the MIUI/HyperOS version in the settings

Make sure you are connected to the right Wi-Fi network

Remember the current settings DNS (kickback)

Reboot your smartphone after the changes-->

Alternative ways to disconnect IPv6 Android

If Xiaomi does not have a direct option to disable IPv6, You can use workarounds. These methods work on most Android 10 devices.+, including POCO, Redmi and Black Shark.

Method 1: Through the Developer (ADB)

This will require a computer with installed ADB and the debugging included USB smartphone.

adb shell settings put global preferred_network_mode 1


adb shell settings put global captive_portal_detection_enabled 0

These teams are required to prioritize IPv4. After performing, restart the device.

Method 2: Use of third-party applications

Apps like NetGuard or AFWall+ allow for blocking IPv6-Firewall traffic:

1. Install NetGuard from Google Play.
2. Activate the module in the application settings.
3. In the Rules section add a rule to block IPv6.
4. Restart the device.

Method 3: Change DNS

Some public DNS (For example, 1.1.1.1 from Cloudflare or 8.8.8.8 from Google automatically redirect IPv6-request IPv4, If they find problems, they can change. DNS:

1. Go to the Wi-Fi settings → Choose your network.
2. In the section DNS provide a static address (e.g. 1.1.1.1).
3. Save and reconnect.

Some of the firmware (for example, on Mi Router) 3G with alternative builds) disconnection option IPv6 In this case, it will help to reset the router to factory settings or firmware the official version of the software through MiWiFi.

Features of disconnection IPv6 Xiaomi TV and smart devices

On Xiaomi Mi TVs TV (series A2, P1, Q2) Smart devices (such as Mi Box S) IPv6 Unlike smartphones, there's no direct interface option, but there are workarounds.

For smart devices (Mi Box, smart lamps, cameras):

Most Xiaomi Smart Home devices (such as Mi Home Security Camera or Yeelight) don’t have settings. IPv6 at the firmware level, to limit their access to IPv6, necessary:

1. Shut down. IPv6 on the router (as described above).
2. Or configure firewall rules on the router by blocking IPv6-traffic MAC-device addresses.

💡

On TVs and Smart Devices Xiaomi Shutdown IPv6 Often requires changes at the router level, since the gadgets themselves do not provide such options in the interface.

Checking the results: how to make sure that IPv6 switched off

After making the changes, it is important to check whether or not the changes are IPv6 It's deactivated. There are several ways to do this:

• 🔍 Browser Testing: Open the Website test-ipv6.com or ipv6-test.com. If IPv6 It is disabled, you will see a message of type No. IPv6 address detected.
• 📱 Mobile apps: Utilities like Network Analyzer or Fing show which protocol is used to connect.
• 💻 Command Prompt (for PC): If you are testing through a computer on the same network, follow the command: ipconfig /all Absence of a line with IPv6-Address means that the protocol is disabled.
• 📡 Router Logs: In the router web interface (192.168.31.1), check the Status or Log section. IPv6 inactive.

If the tests show that IPv6 Still active, try it:

1. Reboot the device and router.
2. Check if settings are reset after rebooting (relevant for some versions) MIUI).
3. Make sure that the changes are applied to all network interfaces (Wi-Fi, mobile data, Ethernet).

💡

On some Xiaomi firmware IPv6 It can automatically activate after the system update. To avoid this, disable automatic installation of updates in the settings.
