How to change TTL on Xiaomi devices: 3 proven ways

Changing the TTL (Time To Live) setting on Xiaomi devices can be required in a variety of situations, from setting network rules to bypassing provider restrictions or optimizing traffic.This parameter determines how long a data packet can live on the network before being destroyed - and adjusting it sometimes becomes the key to solving connection or speed problems.

In this article, we will discuss three main ways to change TTL on different devices of the brand: smartphones under control MIUI, Xiaomi Mi Router routers and through ADB-Each method is suitable for specific scenarios, from manual editing of system files to using standard firmware tools. It is important to understand that incorrect settings can lead to loss of network connection or unstable operation of the device, so all actions are performed carefully.

If you are not sure of your technical skills, we recommend that you test the changes on the backup device first or create a backup of current settings, and for those who are willing to experiment, go to the detailed instructions!

What is TTL and why change it to Xiaomi

TTL (Time to Live is the field in the title IP-A packet that specifies the maximum number of routers (hops) a packet can pass through before being discarded. By default, most Xiaomi devices have this setting set to a value. 64 (for Linux/Android) or 128 (Windows devices on a local network, but why would you want to change it at all?

Here are the most common reasons:

  • 🔄 Bypassing ISP restrictions: Some ISPs block traffic with a certain number of ISPs TTL (For example, to combat torrents or VPN).
  • 📡 Routing optimization: reducing TTL It can help to avoid packet looping on a network with incorrect routes.
  • 🛡️ Network Testing: When Diagnosing Connection Problems, Change TTL Helps to identify “bottlenecks».
  • 🖥️ Simulating another device: for example, changing TTL 64 to 128 can “hide” your smartphone under the guise of Windows-PC in the local network.

On Xiaomi devices, the TTL setting can be changed both softwarely (via settings or ADB) and hardwarely (on routers via a web interface).

⚠️ Attention: Change TTL A value below 32 can lead to packet loss and Internet instability. TTL 255 or higher, this can cause routing errors.

Method 1: Changing TTL on Xiaomi smartphones via ADB

For advanced users, the most flexible way is to use ADB (Android Debug Bridge), which works on most Xiaomi smartphones running MIUI, but requires an unlocked bootloader and developer mode enabled.

Here's the step-by-step instruction:

  1. Turn on the developer mode on your smartphone: Go to Settings → About Phone → MIUI version and tap on this item 7 times in a row. After that, the Settings menu → Additional item For developers will appear.
  2. Activate Debugging by USB in the Developer section.
  3. Connect your smartphone to your PC through USB-cable and confirm the debugging permit.
  4. Open the command line (or Terminal) macOS/Linux) and enter adb shell su echo "65" > /proc/sys/net/ipv4/ip_default_ttl Where 65 — newness TTL (can be replaced by any of 1 before 255).

To save the changes after the reboot, you need to edit the /etc/sysctl.conf file (root rights are required):

adb shell


su




mount -o rw,remount /system




echo "net.ipv4.ip_default_ttl=65" >> /etc/sysctl.conf




mount -o ro,remount /system




reboot

⚠️ Note: Some Xiaomi models (e.g. Redmi Note) 10 pro POCO X3 Pro) file /proc/sys/net/ipv4/ip_default_ttl It can be protected from recording, and in this case, only the firmware of the custom core will help.

Method 2: Configure TTL on Xiaomi Mi Router routers

If you need to change the TTL on the Xiaomi Mi Router (for example, Mi Router 4A, Mi Router AX6000 or Mi Router 3G), this can be done via the web interface or SSH.

For standard firmware (MIUI for routers):

  1. Connect to the router via Wi-Fi or Ethernet.
  2. Open your browser and go to 192.168.31.1 (or miwifi.com).
  3. Log in (login and password from the sticker on the router).
  4. Go to Additional settings → Network settings → IP settings.
  5. Find the TTL field (which may be called Default TTL or IP TTL) and set the desired value.
  6. Save the settings and restart the router.

For OpenWRT-based firmware (Padavan, PandoraBox):

If your router has custom firmware installed, you can change TTL via SSH:

ssh admin@192.168.31.1


echo "net.ipv4.ip_default_ttl=65" >> /etc/sysctl.conf




sysctl -p

Model routerSupport for TTL changeMethod of setting upIs firmware required?
Mi Router 4AYes.Web interface or SSHNo.
Mi Router AX6000Yes (limited)Only SSH.No.
Mi Router 3G/4CYes.Web interfaceNo.
Mi Router MiniNo.—Yeah (Castom firmware)

💡

If the router lost internet after changing the TTL, try to return the value to 64 and restart the device. Sometimes providers block non-standard settings.

Method 3: Change TTL through applications (without root)

If you don’t have root rights or don’t want to use ADB, you can try specialized apps from Google Play.However, most require an unlocked bootloader or only work on older versions of Android.

Here is a list of proven utilities:

  • 📱 TTL Editor: A simple editor to change TTL No root (not working on all Xiaomi devices).
  • 🛠️ NetGuard allows you to manage network rules, including TTL (requires adjustment through ADB).
  • 🔧 Termux is a terminal emulator through which you can manually execute sysctl commands (super user rights are required).

Example of Termux usage:

  1. Install Termux from Google Play or F-Droid.
  2. Enter the commands: pkg install tsu tsu echo "65" > /proc/sys/net/ipv4/ip_default_ttl
  3. Check the change by the team: cat /proc/sys/net/ipv4/ip_default_ttl

⚠️ Attention: Apps like TTL Editor may not work with Xiaomi MIUI 12+ Because of the security constraints, in this case, the only thing left is ADB ornament.

Check the current TTL value on Xiaomi

Before you change TTL, it's helpful to know its current value, and you can do this in a number of ways:

On a smartphone:

  • 📱 Through Termux: cat /proc/sys/net/ipv4/ip_default_ttl
  • 🖥️ Through ADB: adb shell cat /proc/sys/net/ipv4/ip_default_ttl

On the router:

  • 🌐 Through the web interface (State of the Union section) → Network statistics).
  • 🐧 Through SSH: sysctl net.ipv4.ip_default_ttl

You can also check TTL from the side, for example, from another device on the network using the ping command:

ping 192.168.31.1

The answer will be a line of ttl=64, which is the current value.

What happens if the TTL doesn’t change?
If after all the manipulations, the meaning TTL The reasons may be as follows: 1. MIUI: On newer firmware versions, Xiaomi blocks system files from being changed. The solution is to roll back to an older version or install custom firmware. 2. Kernel restrictions: Some models (e.g., Redmi) 9A) silhouette TTL In this case, only the replacement of the firmware will help. 3. VPN: If you use VPN-applications (e.g. Xiaomi) VPN), they can drop TTL - to the standard value. VPN 4. Error of Rights: When used ADB or Termux make sure you have superuser rights (su).

Frequent Mistakes and How to Avoid Them

When changing TTLs on Xiaomi devices, users often face typical problems, and here are the most common ones and ways to solve them:

Mistake.Reason.Decision
TTL resets after rebootingChanges not saved in sysctl.confEdit /etc/sysctl.conf file (root required)
Permission denied when writing in /proc/sys/Not enough rights.Use su or get root access
The Internet is gone after the change of TTLValue too low (<32)Return TTL to 64 and restart the device
TTL settings are not saved on the routerFirmware failure or manufacturer restrictionUpdate your firmware or install a custom one (like Padavan)

Another common problem is the conflict with the network rules of the provider, where some operators (such as Rostelecom or Beeline) block traffic from non-standard TTL. If the Internet stopped working after the changes, try:

  1. Return TTL to default value (64).
  2. Contact the provider and clarify their TTL policy.
  3. Use a VPN to mask the real TTL.

💡

On Xiaomi devices with MIUI 13+, changing TTL without root is almost impossible due to tightened security restrictions, in which case the only reliable way is to firmware the custom core.

Can I change TTL to Xiaomi without root?
On most modern Xiaomi devices (with MIUI 12+), it is impossible to change TTL without root rights. The exception is Mi Router routers, where this is done through the web interface. Smartphones will require either a temporary ADB or root access for permanent editing.
What is the optimal TTL value for torrents?
To bypass the restrictions of torrent trackers are often recommended to install TTL However, the effectiveness depends on the provider: some block traffic by other parameters (for example, by using the same parameters). TCP-flag MTU). Before changing, check the current recommendations on your tracker forums.
Why does Wi-Fi not work after changing TTL?
Too low a TTL (e.g. 10-20) can cause packets to fail to reach the router. Return the value to 64 and restart the device. If the problem persists, check the router's settings - it may be blocking devices with non-standard TTL.
Can I change TTL to Xiaomi through Recovery Mode?
No, Recovery Mode does not provide access to network settings. To change TTL, you either need a downloaded device with superuser rights or an ADB/Fastboot connection (but there are limited options).
Will the resetting of settings return the TTL to factory value?
Yes, hard reset will return TTL to its standard value (64 for Android).However, if you changed sysctl.conf, you may need to flash the device to completely reset.
