How to turn on top internet speed on Xiaomi phone: the full guide 2026

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

Have you noticed that mobile internet or Wi-Fi speeds on Xiaomi suddenly drop, even though the operator or provider promises high rates? The problem isn't always with the tariff or router. Most often, hidden MIUI restrictions, improper network settings or background processes that "steal" traffic. In this article, we'll discuss 7 working ways to turn on full Internet speeds on Redmi, POCO and Mi smartphones - from basic settings to advanced tricks for power users.

It's important to understand that speed depends on three key factors: hardware capabilities (modems, antennas), software constraints (MIUI settings, background applications) and external conditions (network coverage, base station load), and we'll focus on what can be optimized on your own without going to the service center.

If you use Xiaomi with support 5G (For example, Redmi Note 12 Pro+ Xiaomi 13T), but not faster than 100 Mbps – most likely, the phone is working in mode 4G/LTE And the owners of budget models (POCO M5, Redmi 10A) Often faced with artificial speed limits due to energy-saving algorithms MIUI. Next – step-by-step solutions for each case.

1. Checking the current speed: basic tests before setting up

Before you optimize your network, you need to understand where the connection is inhibiting, and use these tools to diagnose:

• 📊 Speedtest by Ookla is a classic application for measuring ping, load/return speeds. Run the test 3 times in a row and take the average.
• 🌐 Fast.com (from Netflix) – shows real-world data streaming speeds, which is important for high-resolution video.
• 📡 CellMapper – analyzes the strength of the mobile network signal (useful for the mobile network) 4G/5G). It shows which tower the phone is connected to and how loaded it is.
• 🔍 MIUI Diagnostics – checks the integrity of network drivers and runs through code ##4636##.

⚠️ Note: If the speed on Wi-Fi and mobile networks is equally low, the problem may be in the future. DNS-servers or operator restrictions. If mobile Internet is slowing down, see the settings section. APN. If both types of connections are slow only in certain applications (like YouTube or Telegram), the settings of those programs or background optimization are to blame. MIUI.

2. Optimizing the mobile Internet (4G/5G)

Xiaomi smartphones often default to aging networks (3G/2G) compatibility mode to save battery power.This limits speeds to 50-100 Mbps even on 5G-enabled devices.

1. Open the Settings. → SIM-maps and mobile networks.
2. Choose yours. SIM-card (if there are several).
3. Go to Network Type or Preferred Network Type.
4. Install: For 5G-smartphone: 5G/4G/3G/2G (car) or Only 5G (if the cover is stable. 4G-device: 4G/3G/2G (car) or Only LTE.

Improved 4G (VoLTE)

⚠️ Note: On some models (POCO X3 Pro, Redmi Note 11) after changing the network type, you may need to restart the phone to make the changes effective. SIM-Cards – it artificially limits speed to 300 Kbps.

Critical Mistake MIUI: Some firmware (especially regional versions for India or China) may not have 5G Only option, even if the phone supports this standard, in which case changing the firmware region or manually editing the build.prop file (instructions in the section for advanced users) will help.

3.APN setup for maximum speed

APN (Access Point Name is the gateway through which your phone connects to the carrier's Internet. APN may limit the speed to 2G even 5G-Smartphone. How to check and fix it:

1. Go to Settings. → SIM-maps and mobile networks → [Yours. SIM] → Access points (APN).
2. If there are several profiles, choose the one that matches your operator (for example, Internet.beeline.ru for Beeline).
3. Click on profile and check key parameters: Parameter Value (example for MTS) Explanation MTS Internet Name Arbitrary name APNinternet.mts.ru Main gateway address Type authentication PAP or CHAP Generally does not affect the speed Type APNdefault,supl Must enable default APNIPv4/IPv6IPv6 protocol can speed up the connection
4. Save the changes and restart the phone.

💡 Useful advice: If your operator has official settings APN For maximum speed (e.g. internet.max.mts.ru), use them. You can check the current parameters on the operator's website or by phone support. APN from VPN-Applications (e.g. 10.0.0.1 in the Proxy field) – they can inhibit the connection.

4. Wi-Fi Acceleration: Channel Choice, Standard and DNS

If the speed problem only occurs when you connect to Wi-Fi, the reasons may be in the settings of the router or phone, starting with optimization on the Xiaomi side:

• 📶 Wi-Fi standard: In the settings of the router, install 802.11ac (for 5 GHz or 802.11ax (Wi-Fi 6), if your Xiaomi supports them.Old standards (802.11n) limit speed to 150 Mbps.
• 🔄 Auto Connection: Disable the option Automatic Connection to Open Networks in Settings → Wi-Fi → It'll prevent you from connecting to slow public hotspots.
• 🔒 Protection: Use WPA3 instead WPA2 — Not only is it safer, but it can also speed up connection on modern devices.
• 🌍 DNS: Replace. DNS-Public servers of the operator (Google, Cloudflare) to reduce ping and speed up the loading of sites.

🔧 Shifting guide DNS Xiaomi:

1. Connect to your Wi-Fi network.
2. Go to Settings → Wi-Fi, click on the name of your network.
3. Select Change Network → Additional settings → IP settings.
4. Install Static and write: DNS 1: 1.1.1.1 (Cloudflare) DNS 2: 8.8.8.8 (Google)
5. Save and reconnect to the network.

⚠️ Attention: If after the shift DNS Some sites (such as banking or government) have stopped opening, return settings to the site. DHCP (This is due to geolocation locks that bypass through DNS operator.

💡

To check which one DNS It works faster on your Xiaomi, use the app DNS Changer. It tests the response rates of different people. DNS-servers and select the best.

5. Hidden MIUI settings for power users

If standard methods don't work, it's time to dig deeper, and there are hidden parameters in MIUI that can artificially limit speed, and here's how to find them and change them.

🔹 Engineering menu mode (for the 4G/5G)

This method allows you to manually select the frequency ranges that your phone modem will use, and is suitable for users who know what frequencies their carrier supports.

1. Enter the dialer code: ##4636##
2. Select Phone Information (or Phone Information).
3. Scroll down to Set preferred network type and set the maximum possible mode (e.g. NR/LTE/TD-SCDMA/GSM for 5G).
4. To manually select frequencies, click Band Selection and tick your operator’s ranges (check them on the provider’s website).

🔹 Editing build.prop (root only)

This method requires superuser rights and can cause the phone to function unstable. Use at your own risk.

In /system/build.prop, find the following lines:

ro.telephony.default_network=9


persist.radio.apm_sim_not_pwdn=1




persist.radio.sib16_support=1

And replace them with:

ro.telephony.default_network=20 # Forcedly Includes LTE+5G


persist.radio.apm_sim_not_pwdn=0 # Disables modem power saving




persist.radio.sib16_support=0 # Removes speed limits

After the changes, restart your phone.

💡

Changing build.prop can lead to loss of warranty and unstable network performance. Before editing, back up the file!

6.Firmware problems and their solution

Sometimes slow internet on Xiaomi is a bug of a particular version of MIUI. Here are the typical scenarios and ways to fix them:

• 🐞 Bug with speed limit after the update: For example, in MIUI 14.0.3 for Redmi Note 11 Pro+ There was a limiting bug 5G up to 300 Mbps. the solution is to roll back to the previous version or wait for the patch.
• 🔄 Regional restrictions: Firmware for India or China may block some bands 4G/5G. Solution – changing the region through Settings → Additionally. → Region (requires an unlocked bootloader).
• 📦 Google Play Services conflict: Google's background processes can 'steal' traffic, solution to limit background activity in Settings → Annexes → Application management → Google Play Services → Battery → Background restriction.

🔍 How to check if the firmware is to blame:

1. Install an alternative launcher (like Nova Launcher).
2. Run the speed test in Safe Mode (hold the off button → Safe Mode).
3. If the speed in safe mode is higher, one of the installed applications is to blame.
4. If the speed has not changed, the problem is in the firmware or “iron”.

⚠️ Note: If after the update MIUI missing 5G or the coating deteriorated 4G, Don't rush to reset. First, check if the settings are reset. APN or network type (see section 3). Often a simple phone reboot helps.

7. Hardware restrictions: when nothing helps

If you’ve tried all the software methods, but the speed of the Internet on Xiaomi remains low, the problem may be in the hardware:

• 📡 A damaged antenna: Phone drops or moisture can disrupt the connection of the antenna to the motherboard. Symptoms: the signal is constantly floating, the speed drops when the phone changes position.
• 🔋 Worn modem: In older smartphones (Redmi) 4X, Mi A1) The modem can degrade over time, losing the ability to hold a high-speed connection.
• 🔌 Faulty. SIM-Slot: Oxidation of contacts or mechanical damage to the slot leads to poor contact with the slot SIM-a map that limits the speed to 2G.

🔧 Self-diagnosis:

1. Check the speed with another. SIM-If the speed has increased, the problem is in the old one. SIM or.
2. Install the Network Signal Guru app and see the signal level (in dBm). The values below -100 dBm indicate poor coverage.
3. If the phone is warming up in the upper part (where the modem is located), it may indicate overheating of the chip, which artificially limits speed.

💰 Replacement of an antenna or modem in the service center will cost 1,500-4,000 rubles, depending on the model. For phones older than 3 years, it is often cheaper to buy a new device than to repair an old one.
