Ping on Xiaomi router: how to reduce latency to a minimum?

Have you noticed that in online games characters are teleported, video on Twitch is constantly slowing down, and voice in Discord sounds with a delay? The culprit of these problems is high ping (network response delay), and often it comes from your Xiaomi router. Even if you have a tariff at a stated speed of 1 Gbps, a real ping can spoil the entire Internet experience.

In this article, we will discuss 10 Proven ways to reduce ping specifically on Xiaomi routers (including Mi Router models) 4A/4C/4Q, AX3600, AX6000 Some methods affect firmware settings, others involve physical location of the device, and still others require changing the connection settings. Importantly, not all tips are equally effective - the result depends on your provider, type of connection (optics)./ADSL) and network loading.

Before you start, check the current ping. you can do this through the command ping google.com -n 20 In the Windows command line (or ping) -c 20 google.com at Terminal macOS/Linux). Optimal values:

• 🎮 For games: up to 30 ms (ideal - up to 15 ms)
• 📺 For streams. 4K: 50ms
• 💼 For video calls: up to 100 ms

If your performance is worse, we will start optimizing!

1. Optimization of Wi-Fi channel: choose free frequency

The most common reason for high ping on Xiaomi is an overloaded Wi-Fi channel, where routers automatically choose a channel when turned on, but over time it can be clogged by neighboring networks, especially for apartment buildings with dozens of devices sitting on the same channel.

To find a free channel:

1. Install the Wi-Fi Analyzer (Android) or NetSpot (iOS) app on your smartphone.
2. See which channels (1–13 for 2.4 GHz or 36–165 for 5 GHz) are least loaded.
3. Go to the router web interface (192.168.31.1 or miwifi.com) → Wi-Fi settings → Additional settings.
4. Manually set the selected channel (for example, 6 for 2.4 GHz or 48 for 5 GHz).

💡

On Xiaomi routers AX3600 And newer, 5GHz is better, and there's less interference, but less range. For stability in games, choose 36-48 or 149-165 channels (DFS).

If you have a dual-band router (AX1800, AX6000), divide the devices by frequency:

• 🖥️ PC/console (where ping is important) – connect 5GHz or cable.
• 📱 Smartphones/tablets – leave at 2.4 GHz (large radius).
• 💡 Smart home (lamps, sensors) – only 2.4 GHz.

2.Amendment MTU: Hidden parameter that affects ping

MTU (Maximum Transmission Unit: The maximum size of a data packet that your router can transmit without fragmentation. If the value is set incorrectly, the packets are cut into pieces, which increases latency. MTU Most providers have 1,472 or 1,500, but sometimes manual adjustments are required.

How to change MTU Xiaomi:

1. Go to the router's web interface (192.168.31.1).
2. Go to the Additional settings → Network → WAN.
3. Find the field. MTU (It can be hidden under "Show additional parameters»).
4. Try the values of 1472, 1492 or 1500 (save and test the ping after each change).

A critical feature of Xiaomi routers: on some models (for example, Mi Router) 4A) change MTU Resets after restarting. To fix the value, update the firmware to the latest version or use an alternative firmware (more on this below).

3. Incorporate QoS (Quality of Service) to prioritize traffic

QoS is a feature that distributes network bandwidth between devices according to priority, for example, you can give the maximum priority to a gaming console or PC so that ping in games does not jump. On Xiaomi routers, QoS works differently depending on the model:

Instructions for AX3600/AX6000:

• 🎮 Go to Settings. → QoS.
• 🔄 Enable the function and select Priority mode by device.
• 📱 Add in. MAC-address of your PC/console (you can find it in Settings) → Local area network → Connected devices).
• 🔝 Set a High Priority for Him.

💡

QoS is only effective if the network is loaded (for example, someone is pumping torrents).

4. Firmware Update: Bug Fixing and Optimization

Manufacturers regularly release firmware updates that fix network bugs, including those associated with high ping. On Xiaomi routers, updates are checked automatically, but sometimes manual updates are required.

How to update firmware:

1. Go to the web interface (miwifi.com).
2. Go to General settings → Update firmware.
3. If a new version is available, click Update.
4. Wait until the router is finished (the router will restart).

Do not turn off the router power during the process.|

Connect the router to the UPS (if any)|

Download backup of settings (General settings) → Backup)|

Check that the provider’s cable is stable.

-->

If automatic updates don't help, you can install beta firmware (available for some models via Mi Community).

⚠️ Warning: Beta firmware may contain critical errors that lead to router bricking, and only install them if you are ready for a possible reset before factory settings.

For Mi Router models 4A and AX3600 There are alternative firmware based on OpenWRT, which give more opportunities for fine-tuning the network (including advanced QoS and change). MTU). Installation requires unlocking the bootloader and technical skills.

5. Optimization DNS: Why Standard Servers Are Slowing Down

By default, the Xiaomi router uses DNS-servers of your provider, which are often slow or late. DNS (Google or Cloudflare can reduce ping by 10 to 30 ms.

How to change DNS:

1. Go to the Additional Settings → Network → WAN.
2. Find the Main Fields DNS and alternative DNS.
3. Enter addresses (e.g. 1.1.1.1 and 8.8.8.8).
4. Save and restart the router.

Recommended DNS-ping-reducing servers:

• 🌍 Cloudflare: 1.1.1.1 and 1.0.0.1 (fastest for most regions)
• 🔍 Google DNS: 8.8.8.8 and 8.8.4.4 (stable, but sometimes slower)
• 🛡️ AdGuard DNS: 94.140.14.14 and 94.140.15.15 (blocks ads) + low-ping)

💡

To check the speed DNS, Use nslookup in the command line or DNSPerf.

6.Physical optimization: router and cable location

Even the most advanced settings won’t help if the router is in the wrong place or using poor-quality cables.

Router location:

• 📡 Install the router in the center of the apartment, at an altitude of 1-1.5 m from the floor.
• 🚫 Remove metal surfaces, microwaves and other sources of interference.
• 🌿 Avoid placing near aquariums or houseplants (moisture worsens the signal).

Cables and connections:

• 🔌 For gaming devices, use an Ethernet cable (even 100 Mbps is better than Wi-Fi).
• 🔄 If you use PPPoE, check the quality of the telephone cable (for the use of PPPoE). ADSL) or optical patch cord (for GPON).
• 🔌 Replace Cheap Cables with Certified Cables Cat.5e or Cat.6.

If you have Xiaomi AX6000 Or another model that supports Mesh, add a second router in repeater mode, which will help you evenly distribute the load and reduce ping in remote rooms.

7. Disabling unnecessary functions: what is stopping the network

Xiaomi routers out of the box include many features that can increase latency.

What can be safely disabled:

• 🔄 IPv6 (If your provider does not support it. Pathway: Additional settings → Network → IPv6.
• 📡 Guest network (if not used). Path: Wi-Fi settings → Guest network.
• 🔒 Parental Control and Filtration MAC-addresses (if not required).
• 🔄 IGMP Proxy (if not used) IPTV). Path: Additional settings → IPTV.

Functions that are better left:

• 🛡️ Firewall (protects against attacks, but can add 1-2 ms to the ping).
• 🔄 DHCP-server (disabling will result in manual configuration) IP on all devices).

💡

On Xiaomi routers AX3600 and newer has a function OFDMA (In the Wi-Fi settings → It's better left on, because it optimizes traffic for multiple devices.

8.Reset to factory settings: Last chance

If nothing works, do a full router reset, which will remove all settings, including possible configuration errors that increase ping.

How to reset Xiaomi to factory settings:

1. Press and hold the Reset button (usually located on the back) for 10-15 seconds.
2. Wait for the reboot (indicators should blink).
3. Connect to the network. Xiaomi_XXXX (password is indicated on the router sticker).
4. Set up your router again by following the tips from this article.

⚠️ Note: After reset, all devices will be disconnected from Wi-Fi, and port settings, QoS and Wi-Fi settings. DNS Pre-reset important parameters (for example, data to connect to the provider).

If the ping remains high even after the reset, the problem may be on the provider's side.

• 📶 Signal level on the line (for ADSL/GPON).
• 🔌 Channel loading (possibly one of the neighbors "selects" the speed).
• 🔄 Routing traffic (sometimes providers route packets through congested nodes).
