How to Make Your Internet Faster on Xiaomi: A Complete Guide to Accelerating Your Network

Why the Internet on Xiaomi is slowing down and how to fix it

Slow internet on Xiaomi devices is a problem that one in three users encounter, and the reasons can be both in the settings of the gadget itself and external factors, from an overloaded router to restrictions on the provider. In this article, we will discuss all possible ways to speed up the Internet – from basic to advanced, including hidden settings. MIUI, optimisation DNS, Choosing the Right Wi-Fi Frequencies and Even Hardware Solutions.

It is important to understand that the speed of the Internet depends on a set of factors.+ Wi-Fi 6 can theoretically deliver up to 9.6 Gbps, but in practice, the speed is often limited by router settings or provider fare. TV.

Start with simple methods that don't require technical knowledge, and gradually move on to more complex solutions, and if you're not confident, don't worry: each section contains step-by-step instructions with illustrations (in text format) and warnings about possible risks.

1. Checking the current Internet speed

Before optimizing your network, you need to understand how fast you are and whether it meets the provider’s stated tariff.

• 📊 Speedtest.net is a classic service from Ookla with servers around the world. Shows ping, download/return speed and connection stability.
• 🌍 Fast.com is a Netflix service optimized to check streaming speeds. Perfect for Mi users TV.
• 📱 MIUI Network Speed Test - built-in test in Xiaomi settings (available on smartphones with a smartphone) MIUI 12+). Path: Settings → Connections and sharing → Network speed test.

Do the test at least 3 times at different times of the day to help identify peak network loads. For example, in the evening the speed often drops due to the large number of connected users in your area. If the results are consistently lower than the provider's stated 30% or more, this is a reason for optimization.

⚠️ Note: When testing, turn off all backgrounds of the application and VPN (Background downloads of updates or torrent clients may distort results.

2. Optimizing Wi-Fi settings on Xiaomi

Wi-Fi settings by default MIUI Not always optimal. Here are the key parameters that we need to change:

Selecting the correct frequency (2.4 GHz vs 5 GHz)

Modern routers support two bands:

• 📶 2.4 GHz – Long range, but low speed and high load (a lot of interference from neighboring networks.
• 🚀 5 GHz – High speed and less interference, but less range. Optimal for Xiaomi smartphones and TVs in the same room with the router.

How to switch to 5 GHz:

1. Open the Settings. → Wi-Fi.
2. Click on your network name and select Change Network.
3. In the Frequency (or Range) section, select 5GHz (if available).
4. Save the settings and connect again.

Enabling Wi-Fi 6 mode (802.11ax)

If you have a smartphone (such as Xiaomi) 13 pro POCO F5) The router supports Wi-Fi. 6, activate this mode to increase the speed of 30-40%:

1. Go to Settings → Wi-Fi → Additional settings.
2. Select Wi-Fi Mode (or Wi-Fi Standard).
3. Set the value 802.11 a/b/g/n/ac/ax (or just wifi. 6, if there is such a clause).

Important: If you turn on Wi-Fi 6 The network is unstable, return the setting to 802.11 a/b/g/n/ac — Some routers are not working well with the new standard.

Disable the "Intelligent Switch" function

V MIUI There's a Wi-Fi Smart Switch that automatically switches the device to the mobile network when the Wi-Fi signal is weak, but it often doesn't work correctly, causing a loss of speed:

1. Open Settings → Connections and Sharing → Wi-Fi.
2. Click on the three dots in the upper right corner and select Additional Features.
3. Turn off the option of Intelligent Switching.

Select the 5GHz range (if available)|

Enable Wi-Fi 6 (for supported devices)|

Deactivate "Intelligent switching"|

Update the router’s firmware (via the web interface)-->

3.Tune in. DNS speed up the Internet

Domain name system (DNS) Converts the addresses of sites (e.g. mi.com) to IP-Standard addresses. DNS The service provider is often slow. DNS Google, Cloudflare or Yandex can speed up the loading of pages on the Internet 20-50%.

How to change DNS to Xiaomi:

1. Go to Settings → Connections and Sharing → Private DNS.
2. Select the host name of the private DNS provider.
3. Enter one of the addresses: 🌐 dns.google (Google DNS) ☁️ 1dot1dot1dot1.cloudflare-dns.com (Cloudflare) 🇷🇺 dns.yandex.ru (Yandex DNS, Optimized for Russia)

Save the settings and restart the device.

Use the application to check the effectiveness DNS Benchmark (available on Google Play) It tests the response speed of various devices. DNS-servers and help you choose the best.

⚠️ Attention: Change DNS may block access to certain corporate or regional resources (e.g. banking applications) if, after a shift, DNS Important sites have stopped opening, return settings to the original ones.

4. Accelerating the Mobile Internet (4G/5G)

If you're using the mobile Internet, the speed depends on the network settings, the range support, and the signal quality. Here's how to optimize. 4G/5G Xiaomi:

Selection of priority network type

By default, Xiaomi smartphones can be used 3G So you can save a lot of charge, which is a lot of speed. 4G or 5G:

1. Open the Settings. → SIM-maps and mobile networks.
2. Choose yours. SIM-map.
3. Go to Network Type.
4. Install. 4G (recommended 5G (if maintained).

4.2. disabling background traffic restriction

MIUI By default, it restricts background traffic to save battery life, and it can slow down the loading of content in apps, to remove the restriction:

1. Go to Settings → Connections and Sharing → Data Use.
2. Click on the three dots in the top right corner and select Background Limitation.
3. Disable the restriction for the desired applications (for example, YouTube, Telegram, browser).

4.3. Manual range change 4G/5G (advanced)

This method requires caution and is only suitable for power users. Incorrect settings can lead to loss of network!

If your smartphone is not catching well 4G/5G, You can manually specify supported ranges through the engineering menu:

1. Enter the dialer code ##4636##.
2. Select Phone Information.
3. Scroll down to Set your preferred network type.
4. Select LTE only (4G only) or NR/LTE/TD-SCDMA/GSM (5G only).

For Xiaomi with Qualcomm processor (e.g. Redmi Note 12 Pro)+) You can use the Network Signal Guru app (available on Google Play) to customize your ranges in detail.

💡

If the signal is lost after manually configuring the network, restart the device or reset the network settings in Settings. → System system → Resetting settings → Resetting network settings.

5. Optimization of network settings MIUI

MIUI It has a number of hidden features that can both speed up and slow down the Internet:

5.1. Disconnection of "Traffic savings"

Traffic Saving compresses data, but often leads to lags when you download media.

1. Go to Settings → Connections and Sharing → Traffic Savings.
2. Turn off the slider.
3. In the same menu, click Savings Settings and turn off data compression for all applications.

5.2. Resetting network settings

If your internet speed has dropped for no apparent reason, reset your network settings (this won’t delete personal data, but will erase stored Wi-Fi networks and passwords):

1. Open Settings → About the phone → Reset settings.
2. Select Network Resetting.
3. Confirm the action and restart the device.

5.3. Set-up of parameters TCP/IP (skilled)

Change of parameters TCP/IP It can increase the speed of downloading files:

1. Install the app TCP Optimizer (requires root rights).
2. Choose an Optimal or High Speed profile.
3. Apply the settings and restart the device.

Without root rights, you can change MTU (Maximum Transmission Unit (via the ) ADB:

adb shell settings put global captive_portal_detection_enabled 0


adb shell settings put global captive_portal_mode 0




adb shell settings put global captive_portal_server false

⚠️ Attention: Incorrect settings TCP/IP This may cause you to be unable to connect to some sites or servers.

6 Hardware Methods of Internet Acceleration

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

6.1. Replacement of Wi-Fi antenna (for smartphones)

In some Xiaomi models (such as the Redmi Note 10 Pro), a weak Wi-Fi signal is associated with poor antenna contact.

• 🔧 Check the connection of the antenna cable to the motherboard.
• 🛠️ Replace the antenna with a more powerful one (for example, from Xiaomi Mi 11).

6.2. Use of an external Wi-Fi adapter (for Mi) TV)

Xiaomi Mi TVs TV They often suffer from a weak built-in Wi-Fi module. USB Wi-Fi adapter with Wi-Fi 6 support:

• 🖥️ Suitable models: TP-Link Archer T3U, ASUS USB-AX56.
• ⚡ Requires an adapter powered by USB (Some models need an additional power supply).

Update of modem firmware
