How to speed up the Internet on Xiaomi: from simple settings to advanced tricks

Slow internet on a Xiaomi smartphone or router is a problem that every second user faces, and the reasons can be in both device settings and external factors, from the operator’s overloaded network to outdated firmware. In this article, we’ll break down 10 proven ways to speed up the internet on Xiaomi devices, including smartphones (Redmi Note 12, POCO X5, Mi 11, tablets (Pad 6) and routers (Mi Router) 4A, AX3600).

Feature of Xiaomi technique – deep customization of firmware MIUI, And we're not going to just go with basic tips like "reset the device," but we're going to go into technical nuances, from changing the parameters. MTU Prioritize traffic through Quality of Service (QoS) before setting up, for each method, we will provide step-by-step instructions with screenshots (interface descriptions) and warnings about possible risks.

Importantly, the speed of the Internet depends on three components: the device (modem model, antenna), the network (provider, connection type) and the servers (geolocation, download). We will focus on the first two, because you can't influence the third ones. If after all the manipulations, the speed hasn't increased, the problem may be on the operator's side - check this through tests on other devices.

1.Diagnostics of current speed: tools and basic tests

Before you optimize, you need to understand where the connection is inhibiting, and use these tools to make a precise diagnosis.

• 📊 Speedtest by Ookla is a classic server-select test. Run 3-5 times in a row and take the average. Pay attention to ping (latency) and jitter (stability).
• 🌐 Fast.com (from Netflix) - checks download speeds through Netflix servers, which is relevant for streaming. Shows real bandwidth without "overclocking" the results.
• 🔍 MIUI Network Diagnostics is a built-in tool in Xiaomi smartphones. → Wi-Fi → ⚙️ Additionally. → Diagnostics of the network. It will show the signal level in dBm (optimum: from -30 before -60) Wi-Fi channel (if overloaded).

⚠️ Note: If the speed on Wi-Fi and mobile network differs by 2-3 times, the problem is in the router or its settings. If both networks are slow, the operator or Xiaomi system restrictions (for example, the background traffic limit) are to blame).

For advanced users: check out DNS-service leakage DNS Leak Test, if yours. DNS-The server is different from the given one (for example, instead of Google). DNS It shows the operator's server, it can slow down the loading of sites, it is also useful to check the routing through the command in the terminal (requires). ADB):

adb shell ping -c 4 google.com

2. Optimization of mobile Internet settings (4G/5G)

Xiaomi smartphones often limit the speed of mobile Internet due to energy saving or incorrect APN-So here's what we can do:

Adjustment APN maximum speed

Wrong parameters APN (Access Point Names can reduce speeds by 30 to 50 percent. APN And create a new one:

1. Go to Settings. → SIM-maps and mobile networks → [Yours. SIM] → Access points (APN).
2. Press. + (Add APN) And enter your operator's details. Tele2 Current parameters (2026) are shown in the table below.
3. Save and select a new one. APN Reset your smartphone as active.

⚠️ Note: If after the change APN Internet is gone, check if the mode is turned on 3G Some operators (e.g. Yota) also block manual change. APN — In this case, call for support.

2.2. Compulsory incorporation 4G/5G

By default, Xiaomi can automatically switch to the 3G or 2G to save charge. To fix it. 4G (or 5G, if maintained):

• 📶 Go to Settings. → SIM-maps and mobile networks → [Yours. SIM] → Preferred type of network.
• 🔄 Select Only. 4G (LTE) or 5G/4G/3G/2G (car (if) 5G available).
• ⚡ Enable the Improved option 4G (LTE+), If you have it in your model (for example, in the Redmi Note 11 Pro).+).

💡

If there is a weak signal in your area 4G, Try manually selecting the frequency in the engineering menu. To do this, type in the phone app code ##4636##, then go to Phone Information. → Network settings → Set preferred network type.

2.3. Disabling background traffic restriction

MIUI By default, it limits the speed of background applications:

1. Open the Settings. → Annexes → Application management → Three points (⋮) → Special permits → Background use of data.
2. Select the apps you want to remove the restriction for (e.g. YouTube, Telegram).
3. Activate the Background Data switch and Unlimited Data Access.

⚠️ Attention: This will increase traffic consumption! disable the option for applications that are actively synced (e.g. cloud storage).

3. Wi-Fi acceleration: channel selection, MTU QoS

If slow Wi-Fi is the problem, check the congestion first, use applications like WiFi Analyzer (Android) or the built-in utility in Xiaomi routers, and the optimal channel is the one with the least intersections with neighboring networks.

Change of channel and bandwidth

In Xiaomi routers (for example, Mi Router) 4A, AX3600) The channel setting is done this way:

1. Open the router’s web interface at 192.168.31.1 (the username and password are usually admin).
2. Go to Wi-Fi. → Wi-Fi settings 2.4G/5G.
3. In the Channel section, select Manual and select a free channel (for 2.4 GHz - 1, 6 or 11; for 5 GHz - 36, 40, 44, 48).
4. Set the channel width at 40 MHz (for 5 GHz) or 20 MHz (for 2.4 GHz if there is a lot of interference).

⚠️ Note: Channels 12-14 in the 2.4 GHz band may be banned in your country (for example, only channel 13 is allowed in Russia.

Optimization of the parameter MTU

MTU (Maximum Transmission Unit: Maximum data packet size; incorrect value can fragment packets and slow down speed:

• 📶 For mobile internet: 1472 (if ping to 8.8.8.8 is stable).
• 📡 For Wi-Fi: 1500 (standard value).

To change MTU smartphone:

1. Install the Termux app and type commands: su ifconfig wlan0 mtu 1500 (substitute wlan0 on rmnet_data mobile-internet).
2. Continuous change requires Magisk and a module MTU Tweaker.

3.3. QoS setup on Xiaomi router

Quality of Service (QoS) allows you to prioritize traffic. In Xiaomi routers, it is configured as follows:

1. In the router's web interface, go to Additional → QoS.
2. Enable QoS and select Priority by traffic type.
3. Set the maximum download/return speed (10-15% less than the real speed of your tariff).
4. In the App Priority section, add programs that need more speed (e.g., Zoom, online games).

Make sure the router doesn’t overheat.

Choose a free channel in 5 GHz

Disable the function of "Smart Connect" (Smart Connect)

Update the router to the latest version

Check cables and connectors (if Ethernet is used)

4. Software tricks: disabling unnecessary services and optimization MIUI

MIUI It's known for being heavyweight -- background processes, advertising, and system applications can consume up to 20 percent of traffic:

Disabling Auto Updates and Background Activity

System updates, Mi Video, Mi Browser and other Xiaomi apps are often updated in the background to prevent this:

• 🔄 Go to Settings. → The phone. → Updating the system → ⚙️ → Auto-update and turn it off.
• 📱 For applications: Settings → Annexes → Application management → [Annex] → Mobile data → Background data → Shut down.
• 🚫 B Settings → Battery and performance → Power management applications set for unnecessary applications Mode Restricted.

4.2. Remove Bloatware (embedded Xiaomi applications)

Many Xiaomi apps (Mi Music, Mi Pay, GetApps) cannot be removed by standard means, but they can be disabled or removed via the app. ADB:

adb shell pm uninstall --user 0 com.miui.videoplayer  # Mi Video


adb shell pm uninstall --user 0 com.miui.player       # Mi Music




adb shell pm uninstall --user 0 com.xiaomi.midrop      # Mi Drop

⚠️ Warning: Removing system applications can lead to unstable work MIUI. Before that, create a backup copy through Settings. → Additionally. → Backup and reset.

Resetting network settings

If nothing works, reset your network settings. That will delete all stored Wi-Fi, VPN and mobile network parameters:

1. Go to Settings. → SIM-maps and mobile networks → Resetting Wi-Fi, Mobile Network and Bluetooth.
2. Confirm the action. Once you reboot, reset the networks.

Critical information: On some models (e.g, POCO F3) Network resetting also resets settings IMS (VoLTE/VoWiFi), That could cause problems with voice calls!

5. Hardware methods: antennas, cooling and external modems

If the software methods didn't work, the problem could be the hardware.

Verification of antennas and signals

A weak signal is one of the main reasons for slow Internet.

• 📶 Signal Level in the Engineering Menu (##4636## → Telephone information: Optimal value RSRP for 4G: higher -90 dBm.
• 🔍 The state of the antennas: if the speed dropped after a fall or impact, the antenna contact may have gone away (relevant for the Redmi Note 10 Pro and other models with a metal body).
• 🌡️ Overheating: if the smartphone is heated above 45°C, the modem can artificially limit the speed. AIDA64.

⚠️ Note: On models with Mediatek (e.g. Redmi) 9A) overheating of the modem is a common problem: use heat sink covers or avoid prolonged exertion (for example, online games in the sun).

5.2 Use of external USB-modem

If the built-in modem is weak (relevant to older models like Redmi 5), plug in. USB-modem (e.g. Huawei) E3372) through OTG-adapter:

1. Enable modem modem in settings USB-modem.
2. Connect the modem to the smartphone through OTG.
3. B Settings → Access Point and modem → USB-modem activate the option.

Speeds through an external modem can be 30-50% higher, especially in areas with weak signal.

5.3 Replacement SIM-maps for more modern

Old ones. SIM-Cards (especially Mini-SIM) may not support 4G+ or 5G. Replace it with the latest nano-SIM (2020 and later) in the cabin, and check if you have VoLTE activated, which can limit your speed without it.

💡

If, after the replacement, SIM-If you're not up to speed, ask the operator to "re-register on the network." Sometimes the subscriber data in the billing is updated with a delay.

Alternative solutions: VPN, DNS proxy

Sometimes slow internet is the result of operator lockdowns or suboptimal routing, and in such cases, help:

6.1. Modification DNS-server

DNS-Operator servers can slow down the loading of sites:

• 🌍 Google DNS: 8.8.8.8 and 8.8.4.4
• 🛡️ Cloudflare DNS: 1.1.1.1. and 1.0.0.1.
• 🚀 AdGuard DNS (blocking advertising: 94.140.14.14 and 94.140.15.15

To change DNS smartphone:

1. Go to Settings. → Wi-Fi → [Your network] → Change the network → Additional parameters → Settings IP.
2. Select Static and enter addresses DNS.

For mobile internet use applications like DNS Changer.

6.2. Use of VPN circumvention

Some operators (e.g, Tele2) Throttle (artificially slow down) traffic for certain services (torrents, video). VPN Helps get around this. Recommended services:

• 🔒 ProtonVPN (free, no logs).
• ⚡ Warp by Cloudflare (minimum speed losses).
• 🌐 1.1.1.1 (Cloudflare) – lightweight solution with Warp support+.

⚠️ Attention: Free of charge VPN Often limit the speed yourself. Use paid rates or customize your own for maximum effect. VPN via WireGuard.

6.3. Setup of proxy for specific applications

If only one app (like YouTube) is slowing down, set up a proxy for it:

1. Install ProxyDroid or HTTP Toolkit.
2. Enter the proxy server address (for example, proxy.example.com:8080).
3. In the application settings, specify that it should use a proxy.

7.Firmware and kernel updates: when it really helps

Outdated firmware MIUI The Linux kernel may contain speed-limiting bugs, but updating isn't always secure, especially on custom firmware.

Update MIUI through OTA

Check the relevance of the firmware:

1. Go to Settings → About the phone → System update.
2. If you have an update, download it and install it. Don't interrupt it!

⚠️ Attention: On models POCO and Redmi with unlocked bootloader OTA-updates can lead to bootloop (a looped download). Before updating, check the reviews on forums (for example, check the reviews on the forums, 4PDA).

Installation of the custom core

Advanced users can install custom cores (e.g. FrancoKernel or Kirisakura) optimized for network speed.

1. Unlock the bootloader through the official Xiaomi tool.
2. Install. TWRP and run the core through recovery.
3. In the kernel settings (EX Kernel Manager: activate the options: TCP Congestion Control → BBR WiFi TX Power → High Network Scheduler → FQ_Codel

Critical information: On some models (e.g. Xiaomi) 12T) Custom cores shut down support 5G. Before the firmware check the compatibility of the XDA Developers.

8.Extreme measures: factory reset and equipment replacement

If all methods are tried and the speed is still low, radical steps remain:

8.1. Complete reset (Hard Reset)

This will delete all the data, but it will return the smartphone to a "clean" state.

1. Create a backup through Settings → Additional → Backup and Reset.
2. Go to Settings → Additional → Backup and Reset → Reset settings.
3. Choose to erase all data and confirm.

⚠️ Note: On devices with Dynamic RAM (for example, POCO X4 Pro) after reset, it may be necessary to re-activate the function in the developer settings.

8.2 Replacement of router or smartphone

If the problem is iron, consider upgrading:

• 📶 For the router: Xiaomi models AX6000 or AX9000 Support Wi-Fi 6 and 160 MHz channel width, which gives speed up to 2-3 times.
• 📱 For a smartphone: models with a Snapdragon modem X65 (for example, Xiaomi 13 Pros support 5G+ and 4×4 MIMO, Which is critical for high speeds.

Before buying, check the support for the desired frequencies in your region through the FrequencyCheck service.

💡

If you decide to change routers, choose models with support. OFDMA and MU-MIMO — These technologies significantly improve speed when connecting multiple devices.
