How to increase the speed of the Internet on Xiaomi: from check to optimization

The speed of the Internet on Xiaomi smartphones depends on many factors: from network settings and firmware to external interference and limitations of the provider. Even on top models like Xiaomi 14 Ultra or POCO F6 Pro, users face slowdowns in page loading, jerks in online games or low download speeds. The reasons can lie in hardware limitations (for example, outdated Wi-Fi module in budget models), and in software settings – from background applications to incorrect DNS parameters.

In this article, we will analyze all the ways to diagnose and speed up the Internet on Xiaomi, Redmi and other devices. POCO — From basic checks to hidden functions MIUI. You'll learn how to test your speed correctly, which settings to change first, and what to do if the problem isn't in your phone, but in your router or SIM card. MIUI 14/15, which are not available in Android and can significantly improve connection stability.

1. How to Check Internet Speed on Xiaomi

Before you optimize a connection, you need to objectively assess its current state, and using the wrong testing methods can give false results — for example, the speed in the browser and in specialized applications often varies by 20-30%.

• 📱 Disable all background apps (especially messengers and cloud services) through Settings → Annexes → They consume traffic and distort the results.
• 🌐 Use Speedtest by Ookla or FAST.com (from Netflix) – they show real download/return speeds, not theoretical maximums.
• 📡 Check the speed at different points in the house: the router, in the far corner and next to the window, which will help to identify areas of poor Wi-Fi coverage.
• 🔄 Make sure you do it. 3 test-in-series 1-2 You can get a little bit of a rundown, and you can average the results.

Important: if you are testing mobile Internet (4G/5G), turn off Wi-Fi and vice versa.Simultaneous use of two networks in MIUI can lead to routing conflicts, which will cause the real speed to be lower than expected.See also the network indicator in the notification panel - if instead of "4G+" or "5G" displays "H+" or "3G", the problem may be in the settings of the SIM card or the coverage of the operator.

2. Wi-Fi Optimization: From Channel Selection to Hidden MIUI Settings

Wi-Fi is the most common way to connect, but it's also the most problematic way, and even if the router supports Wi-Fi 6 and the Xiaomi 13T Pro is equipped with an 802.11ax module, the real speed may be many times lower than the stated speed.

Selecting the right range and channel

Modern routers operate in two bands: 2.4 GHz (range but low speed) and 5 GHz (high speed but weak signal through walls). MIUI You can manually specify the priority range:

1. Go to Settings. → Wi-Fi.
2. Click on your network name and select Change Network.
3. Activate the option Additional settings.
4. In the Frequency Range section, select 5GHz (preferably) or Auto (if the router supports both bands).

If your router is running 802.11n/ac/ax, but your smartphone only connects to 2.4GHz, the problem may be channel settings. Use applications like WiFi Analyzer to find the least loaded channel in your region (e.g., channels 1, 6, or 11 for 2.4GHz).

💡

If the speed hasn't changed after the channel change, try restarting the router and smartphone at the same time, and sometimes the network settings cache in MIUI is reset only after a full reboot.

Hidden Wi-Fi settings in MIUI

MIUI has hidden parameters in the firmware that are not displayed in the standard menu.

1. Open the phone app and enter the combination: ##4636##
2. Go to the Wi-Fi Information section.
3. Pay attention to the parameters Connection speed (should be close to the maximum for your standard) and Signal strength (optimally: -50 dBm and above).
4. If the speed is below 150 Mbps when connected to 5 GHz, try changing Wi-Fi mode in the router settings to 802.11ac (instead of mixed b/g/n/ac).

Another useful trick is to disable the Smart Wi-Fi Switch function, which in MIUI often works incorrectly.

1. Go to Settings → Wi-Fi → More
2. Turn off the option of Automatic Open Network Connection and Smart Mobile Data Switching.

3. Accelerating the Mobile Internet (4G/5G): from APN pre-network

Mobile Internet on Xiaomi can be slowed down due to incorrect APN settings, operator restrictions or incorrect network mode.

• 📶 Make sure that the status bar is displayed 4G+ or 5G, not H+ or 3G. If the indicator shows an outdated standard, the problem may be in the SIM card or network settings.
• 🔄 Reboot your smartphone and force reconnect to the network: turn on Flight Mode for 30 seconds, then turn off.
• 📱 Check if traffic savings are activated in Settings → SIM cards and mobile networks → Traffic savings: This feature limits background speed.

3.1. APN setup for maximum speed

Incorrect APN (Access Point Name) settings are one of the main reasons for slow mobile Internet, and even if the smartphone automatically loaded the operator's settings, they can be outdated.

1. Go to Settings → SIM cards and mobile networks → [Your SIM card] → Access Points (APN).
2. Click on the three dots in the top right corner and select New APN.
3. Enter the settings for your operator (see the table below for examples for popular providers).
4. Save your settings and select a new APN as active.

If the Internet is gone after changing the APN, go back to the standard settings and contact the operator for support - there may be speed limits on your tariff.

3.2. Selection of network mode: 4G, 5G or Auto?

In MIUI, you can manually specify the priority network type, and the default is Auto, but sometimes it leads to an unstable connection, to change the mode:

1. Go to Settings → SIM cards and mobile networks → [Your SIM card] → Preferred network type.
2. Choose one of the options: 4G Only (LTE) if 5G is unstable in your region, 5G/4G/3G/2G (auto) for maximum compatibility, 5G only if you are confident in coverage (relevant to the Xiaomi 13/14 series with 5G support).

⚠️ Note: Some Redmi models (e.g. Redmi Note 12) use only 5G If the phone calls stop coming after the change in settings, return the car.

Programmatic acceleration methods: from cleaning the cache to changing the DNS

Even with ideal network settings, speeds can be slowed by software limitations in MIUI.

• 🧹 Clearing the cache DNS: enter in the address bar of the browser chrome://net-internals/#Dns (for Chrome) and press Clear host cache.
• 🚫 Disabling Auto Updates: Go to Settings → Annexes → Auto Update Apps and Select Only via Wi-Fi or Never.
• 🔧 Resetting network settings: Settings → The phone. → Resetting settings → Resetting Wi-Fi, mobile network and Bluetooth settings, which will delete all stored networks and APN, So write down your passwords in advance.
• 🛡️ Virus Check: Some malicious apps consume traffic in the background.Use Security from Xiaomi to scan.

One of the most effective ways to accelerate is to change DNS-servers. They're used by default. DNS Your provider, who often work slowly, to change them:

1. Go to Settings → Connections and Sharing → Private DNS.
2. Select the Private DNS Host Name and type: dns.google for Google DNS. 1dot1dot1dot1.cloudflare-dns.com for Cloudflare.

Close all background applications

Disable VPN (if used)

Reboot the router (for Wi-Fi)

Enable flight mode for 30 seconds and turn off

Check that no traffic savings are activated-->

5. Hardware restrictions: what to do if iron brakes

If all software methods have been tried, but the speed remains low, the problem may be the hardware limitations of your device.

• 📡 Outdated Wi-Fi: Redmi budget models (e.g. Redmi) 9A) equipped with a Wi-Fi 4 module (802.11n), which cannot physically provide speeds above 150 Mbps. The solution is to use an Ethernet cable via a USB-OTG adapter (if the model supports the).
• 🔋 Processor overheating: when heated above 60°C MIUI Automatically restricts performance, including network operations. Check the temperature in Settings → The phone. → Battery status.
• 🔌 Antenna problems: If mobile internet speed drops when holding the phone in a certain way, it may indicate that the antenna plume has detached (relevant to the Internet). POCO X3 Redmi Note 10, the solution is the service center.

For flagship owners (Xiaomi 12/13/14 series), it is worth checking whether the processor's power saving mode is activated. In MIUI, it can limit the clock frequency of the communication module.

1. Go to Settings → Battery and Performance → Performance Modes.
2. Choose High Performance (instead of Balanced or Energy Saving).

⚠️ Attention: On some firmware MIUI High performance can lead to accelerated battery discharge, if after activation the phone began to run out of power. 3-4 One hour, return the balanced.

6.Router problems: when it's not the phone's fault

In 60% of cases, low Internet speeds on Xiaomi are not due to the phone, but to incorrect router settings.

• 🔄 Reboot router: disconnect it from power for 1 minute.This will reset cache and time constraints.
• 📦 Router firmware update: legacy software may limit speed for individual devices. Check the current version in the router's web interface (192.168.1.1 or 192.168.0.1).
• 🔒 Limitations on MAC-address: some routers (especially from providers) limit speeds for unknown devices. MAC-The address of your Xiaomi whitelist.
• 🌍 Regional settings: If the router is purchased abroad, the frequency range may be limited in its settings. For example, in the US and Europe, different 5 GHz channels are used.

If you have a dual-band router, try splitting 2.4 GHz and 5 GHz networks into different SSIDs (names), which will allow you to manually select the range on your smartphone.

1. Go to the router's web interface.
2. Find the Wi-Fi section or Wireless Network.
3. Turn off the option of Combining ranges (or Smart Connect).
4. Give different names for 2.4 GHz and 5 GHz (e.g, MyWiFi_2G and MyWiFi_5G).

💡

If the internet speed on Xiaomi is lower than on other devices on the same network, the problem is precisely in the phone or its settings. If it slows down on all devices, the router or provider is to blame.

7.Alternative methods: VPN, proxy and specialized applications

If standard methods don't work, you can try out-of-the-box solutions, which don't always work, but in some cases, they can speed up the connection significantly.

• 🔒 VPN To circumvent restrictions: some providers artificially reduce the speed for certain services (for example, torrents or streaming). VPN We recommend Windscribe or ProtonVPN (free versions with restrictions).
• 🔄 Network optimization applications: Internet Speed Meter Lite - monitors speed in real time. Network Signal Guru - analyzes the signal strength and offers optimal settings.
• 📡 Use of external antenna: for models with support USB-OTG (for example, POCO F5) You can connect an external Wi-Fi antenna to an adapter, and that's true for areas with very low signal.

One of the most radical methods is to change firmware to custom (like LineageOS or Pixel Experience), which in some cases gives a speed gain of 15-20% due to an optimized kernel, but this method is only suitable for advanced users, because it requires unlocking the bootloader and can lead to loss of warranty.
