How to improve the Internet on Xiaomi smartphones: from Wi-Fi to mobile network

Slow internet on Xiaomi is one of the most common problems faced by users of both budget Redmi and flagship Mi or Mi. POCO. The reasons may lie in the wrong settings of the smartphone, overloaded router, outdated firmware or even hardware limitations of the model. But in 90% of cases, the connection speed can be increased without going to the service center - just know what parameters to adjust.

In this article, we will discuss practical optimization methods for both Wi-Fi and mobile Internet (4G/5G), including hidden settings MIUI, choice DNS, We're going to focus on problems with delays in online gaming, video buffering, and connection breaks -- typical scenarios where standard tips like "reset your phone" don't work.

Important: All instructions are relevant to the devices on MIUI 12-14 (including HyperOS), but some of the methods are universal for older versions, if your model is released before 2018 (for example, Redmi Note 5 or Mi). A1), Some features may not be available – check the availability of settings individually.

1. Diagnostics of the problem: why is the Internet slowing down?

Before optimizing the network, you need to understand what the problem is, and the slow Internet on Xiaomi can manifest itself in different ways:

• 📶 Low download speed (for example, 1-5 Mbit / s at a tariff of 100 Mbit / s).
• 🎮 High ping in games (200)+ ms) or frequent lags.
• 📺 Continuous video buffering (even in the 480p).
• 🔄 Connection breaks (Wi-Fi or mobile internet is periodically shut down).
• 📱 Different speeds on different devices (on a laptop, the Internet is fast, and on a smartphone – no).

To narrow down the range of reasons, perform a basic check:

1. Measure your speed through Speedtest or Fast.com (run the test 2-3 times in a row).
2. Check the speed on another device (like a laptop or second phone) on the same network.
3. Switch from Wi-Fi to mobile internet (or vice versa) and compare the results.
4. Run the test in Safe Mode (disables all third-party applications): press the power button → Safe regime.

If the speed is low only on Xiaomi, and other devices are fine, the problem is the settings of the smartphone. If the slowdown on all devices, it is the router or the provider. If the mobile Internet is slow even in safe mode, perhaps it is the case. SIM-map or operator settings.

2. Wi-Fi Optimization: Hidden MIUI Settings

By default. MIUI It uses standard Wi-Fi settings, which are not always optimal. Consider hidden settings that can be changed without root rights.

Selection of Wi-Fi range (2.4 GHz vs 5 GHz)

Most modern routers support two bands:

• 📡 2.4 GHz Long range but subject to interference (microwaves, neighbouring networks).
• 🚀 5 GHz – faster and more stable, but worse passes through walls.

How to check which range your Xiaomi is connected to:

1. Open the Settings. → Wi-Fi.
2. Tap by your network name → Look at the frequency line.

If you have a dual-band router but your phone only connects to 2.4GHz, try:

• 🔄 Reconnect manually to the network with 5G in the title (e.g, MyWiFi_5G).
• 📵 Disable Autoconnection in Wi-Fi settings.
• 🔧 In the router settings, disable compatibility with outdated devices (option) 802.11b/g/n → leave out n/ac/ax).

💡

If your Xiaomi doesn’t see a 5GHz network, check if your model supports it. 9A It only works at 2.4 GHz and POCO X3 Pro - on both bands.

Changing Wi-Fi Region (to increase power)

MIUI It limits the power of a Wi-Fi transmitter to regional standards, for example, in Europe, the maximum power is lower than in the United States, which can be changed through a hidden menu:

1. Open the Phone app.
2. Enter the combination: ##546368###
3. Choose Wi-Fi. → Menu (three points) → Advanced.
4. Find the Country Code and install it. US (USA).
5. Save the settings and restart the phone.

⚠️ Warning: After changing the Wi-Fi region, the network may start to conflict with neighboring access points. If you notice a deterioration in communication, return the settings to Auto or the original region.

Disable the "Intelligent Switch" function

V MIUI There is a function of intelligent switching. Wi-Fi/It's a mobile data system that automatically switches the phone to the mobile Internet if the Wi-Fi is weak, and the problem is that it often doesn't work properly, like when you're late on the network.

How to turn it off:

1. Go to Settings. → Wi-Fi.
2. Tap on the name of your network → Network settings.
3. Turn off the option of Intelligent Switching.

It is also recommended to disable Autoconnection to open networks and Notifications about new networks – they create background load on the Wi-Fi module.

3. Mobile Internet setup (4G/5G)

If Internet problems occur when using SIM-maps, check the following parameters:

3.1. Choice of type of network (LTE/5G)

By default, Xiaomi can limit the type of network to save charge. To force the maximum speed:

1. Open the Settings. → SIM-maps and mobile networks.
2. Choose yours. SIM-map → Type of network.
3. Install: For 4G: Only LTE (or LTE/3G/2G, if the coating is unstable. 5G: 5G/LTE/3G/2G (If your tariff supports 5G).

⚠️ Note: If you choose to choose only LTE In a low-coating area, the phone may lose all connection.

Update of settings APN

APN (Access Point Name is a configuration that determines how the phone connects to the operator's Internet. APN speed limiting.

How to update APN:

1. Go to Settings. → SIM-maps and mobile networks → [yours SIM] → Access points (APN).
2. Click on three points → Reset to default values.
3. If that didn't help, add APN manually (options can be taken on the website of your operator).

Example of settings APN MTS (relevant to most regions):

After saving the new APN Restart your phone and check the speed.

Verification of operator restrictions

Sometimes operators artificially limit speed due to:

• 📄 Exhausted traffic (even if unlimited tariff, "fair use" may apply").
• 🔒 Lockdowns IMEI (If the phone is purchased abroad).
• 📡 Overloaded towers (especially during rush hour).

To check:

1. Call the operator and check if there are any restrictions on your number.
2. Try inserting. SIM-If the speed is the same, the problem is not Xiaomi.
3. Install Network Cell Info Lite and check the signal strength (value) RSRP should be higher -110 dB).

4. Optimization DNS: How to speed up the loading of websites

DNS (Domain Name System is a system that converts site addresses (e.g., google.com) into IP-Standard addresses. DNS-ISPs (usually from your carrier or router) may be slow to operate. DNS Speed up page opening and reduce delays.

4.1 How to change DNS Xiaomi

2. Select the host name of a private DNS-provider.
3. Enter the address (e.g. dns.google or 1dot1dot1dot1.cloudflare-dns.com).

Recommended DNS-server:

⚠️ Attention: If after the shift DNS Some sites (e.g., banking sites) have stopped opening, return the standard settings. Some services block access through public services. DNS.

Speed check DNS

To find out which DNS It works faster for you, use the app. DNS Benchmark:

1. Run a speed test for different types of DNS.
2. Choose the two fastest ones and enter them into the settings.

Shift. DNS It's especially effective if you're slow to open a site, but speedtest speed is high, which means it's not the channel, it's the response time. DNS-server.

5. Set up router for maximum speed

If the Internet problem is manifested on all devices, including Xiaomi, the reason is in the router. 4A It can be optimized for speed.

5.1 Optimal settings of Wi-Fi on the router

Go to the router control panel (usually at 192.168.1.1 or 192.168.0.1) and check the following settings:

• 📶 Wi-Fi Channel: Install Auto or select the least loaded channel (use WiFi Analyzer app for analysis).
• 🔄 Channel width: for 2.4 GHz, choose 20 MHz (sustainable), for 5 GHz, 40 MHz or 80 MHz (faster).
• 🔒 Type of security: Use WPA2-PSK or WPA3-PSK (not WEP!).
• 📡 Transmission power: set to High (or 100%).
• 🔄 Mode of operation: for 2.4 GHz — 802.11n, 5 GHz — 802.11ac or 802.11ax (Wi-Fi 6).
