How to Enable Maximum Network Speed on Xiaomi: A Complete Guide to 2026

Have you noticed that the Internet on your Xiaomi is slower than it should be? Download speeds slow, video buffers, and online games are lagging — even with a stable Wi-Fi signal or mobile network? The problem may not lie in the provider, but in the settings of the smartphone itself. The manufacturer often limits the network settings by default to save battery power or avoid overheating. But these restrictions can be removed — and we will show you how to do this.

In this article, you will find 5 proven ways to enable full network speed on Xiaomi, Redmi and POCO devices – from basic settings to hidden MIUI features. We will also analyze why speeds can fall on specific models (for example, Redmi Note 12 Pro+ or Xiaomi 13T), and give recommendations for optimization for different types of connections: mobile Internet (4G/5G), Wi-Fi and even dual-band networks.

Before you start settings, make sure that the problem is not on the carrier or router side. Check this out simply: connect another phone to the same network. If the speed there is normal, then it is your Xiaomi. If the Internet is slow on all devices, first restart the router or contact the mobile operator.

1. Checking the current network speed: basic tests

Before you set up something, you need to understand how fast you are now and how it differs from the declared operator or provider.

• 📊 Speedtest by Ookla is the most popular test app, showing ping, upload/return speed and connection stability.
• 🌐 Netflix's Fast.com -- fast-checks speed without ads, perfect for streaming.
• 📱 MIUI Network Assistant is a firmware-based application (not available on all models) and runs through Settings. → The phone. → Network diagnostics.

Do the test 3 times in a row in different conditions:

1. Wi-Fi next to the router.
2. Mobile Internet (4G/5G) indoors.
3. On the Internet (if possible) on the street.

⚠️ Note: If the speed on Wi-Fi is below 50 Mbps, and on the mobile Internet - below 10 Mbps (for the first time). 4G), The problem requires intervention. 5G normal minimum - 50 Mbit / s.

Compare the results to your carrier or provider's rate, for example, if you have a 100 Mbps unlimited rate and the test shows 20 Mbps, that's a cause for concern. But remember, the actual speed is always lower than the stated rate (due to network losses, tower loads, etc.), Normal deviation is up to 30%.

2. Enable the maximum speed mode 4G/5G

By default, Xiaomi often limits network mode to LTE/4G, even if your smartphone supports 5G. And some MIUI firmware even activates power saving mode, which artificially strangles speed.

Open the Settings. → SIM-Maps and mobile networks and follow the following steps:

Choose. SIM-card (if two of them)|Click "Network type»|Install «5G/4G/3G/2G (auto)” or “Only 5G»|Reboot the phone.-->

• 📶 For Xiaomi. 12/13/14 series and Redmi Note 11/12 Pro: choose 5G (recommended LTE/4G/5G.
• 🔄 For older models (Redmi 9, Mi) 10T): available 4G (LTE) — Choose it.
• ⚡ If there is a paragraph, Include VoLTE/VoNR — activate it (improving call quality and speed).

When you change your settings, reboot your phone, which is a must for the changes. If the 5G option is inactive, check:

1. Does your model support 5G (the list is available on the official website of Xiaomi).
2. 5G is activated in your carrier’s tariff (sometimes a separate option is required).
3. Is the firmware updated to the latest version (more about this in the next section).

⚠️ Attention: On some firmware MIUI for China ROM) option 5G It can be hidden, and in that case, only the flashing on Global will help. ROM or EEA ROM.

💡

If the phone is running faster after 5G is turned on, go back to 4G/3G/2G (auto). 5G consumes 20-30% more power than 4G.

3. Optimizing APN settings for mobile internet

APN (Access Point Name is the "entry point" that your mobile operator provides to the Internet. APN They can limit speed or even block network access, especially after a shift. SIM-maps or firmware updates.

To check and change the APN:

1. Go to Settings. → SIM-maps and mobile networks → [choose SIM] → Access points (APN).
2. Click on the current APN profile (usually one).
3. If you don’t have settings or they’re reset, create a new profile by clicking “+” or “Add APN.”

Enter the settings for your operator (examples for popular providers):

After saving the new APN, select it from the list and restart the phone. If the speed hasn't increased, try it.

• 🔄 Delete all the others APN from the list (sometimes conflicting with each other).
• 📞 Call the operator and clarify the current settings (they may change).
• 🔧 Reset network settings to factory (Settings) → System system → Reset → Resetting network settings).

4 Hidden MIUI settings to speed up network

Xiaomi hides some network options in the engineering menu or special codes, which allow you to manually prioritize the network, disable background traffic restrictions, and even change the settings of the communication module, but beware: improper changes can lead to loss of communication or overheating of the module.

Here are the most useful commands and settings:

• 📡 Engineering menu: Enter ##4636##, then select Phone Information:
• 🔧 Flight mode + Reboot: Quick way to reset network settings without losing data: 1. Enable flight mode. 2. Turn off phone. 3. Pull out SIM-10 seconds card. 4. SIM Back, turn on your phone and turn off flight mode.
• 🚀 Disable background traffic restriction: Go to Settings → Annexes → Application management → Three dots (menu) → Special access → Battery Optimization: Find apps that should work in the background (like instant messengers), and select Unlimited.

For advanced users: If you are confident in your actions, you can change the module settings via ADB. For example, the command below includes 4G channel aggregation (increases speed by 20-50%):

adb shell settings put global captive_portal_detection_enabled 0


adb shell settings put global preferred_network_mode 9

⚠️ Note: Change settings through ADB If the signal is lost after the change, reset the network (Settings) → System system → Reset → Resetting network settings).

💡

Channel aggregation (LTE CA) speed up 4G into 2-3 It works only in areas with good coverage, and you can check the support in the engineering menu or the NetMonster app.

5. Wi-Fi Optimization: Channel Choice, Standard and Mesh Networks

If speed problems occur on Wi-Fi, it may be the wrong router settings or conflict with other devices. On Xiaomi smartphones, there are several ways to improve the reception:

• 📶 Range Selection: Modern routers operate on two frequencies - 2.4 GHz (range but low speed) and 5 GHz (high speed but smaller radius). In the Wi-Fi settings on Xiaomi, you can prioritize 5 GHz: Settings → Wi-Fi → [tap on your network] → Frequency range → 5 GHz
• 🔄 Change channel: If the router automatically selects a channel, it may conflict with neighboring networks. Use the WiFi Analyzer (Google Play) app to find the freest channel, and set it manually in the router's settings.
• 🌐 Wi-Fi standard: In the router, turn on the standard 802.11ac (or wifi 5) squat 802.11n. Xiaomi. 13/14 series and Redmi Note 12 Pro+ Wi-Fi-supported 6 — If your router supports it, activate it.

For owners of Xiaomi Mi Router or Redmi Router there are additional chips:

• 🔗 Mesh Network: If you have multiple Xiaomi routers, combine them into Mesh via the Mi WiFi app. This will eliminate dead zones and speed up roaming between dots.
• 🎯 QoS (Quality of Service): Prioritize traffic for your Xiaomi router MAC-address.

If the speed on Wi-Fi is still low, try:

1. Reboot the router (turn off the socket for 30 seconds).
2. Disable VPN or proxy (they may limit speed).
3. Check if the phone is using a traffic restriction for that network (Settings → Wi-Fi → [network] → Advanced settings → Data Limit).

Software acceleration methods: disabling limits and cache

Sometimes the speed drops, not because of the network, but because of system constraints or overloaded cache.

• 🗑️ Cache Clearing: Go to Settings → Annexes → App management, find Google Play Services and Telephony Services, then clear the cache and data.
• 🚫 Disabling traffic savings: C Settings → Battery and productivity → Save traffic disable this option – it limits background data transfers.
• 🔄 Reset DNS: Sometimes the slow functioning of the Internet is associated with DNS-ISP servers. Change them to Google. DNS: Settings → Wi-Fi → [your network] → DNS → Manually Enter: 8.8.8.8 and 8.8.4.4

If you use a VPN, try:

• Turn it off temporarily and check the speed.
• Change server (for example, in ProtonVPN or NordVPN, select a server with a minimum load).
• Change the protocol (for example, from OpenVPN to WireGuard).

For root-right Xiaomi owners, there's a radical way to turn off BBS (Background Bandwidth Saver), which limits speed in the background.

1. Root access (for example, via Magisk).
2. The BuildProp Editor app.
3. Change of parameter ro.config.hw_quickpoweron=true.

⚠️ Attention: Disconnection BBS This method can lead to increased battery consumption and overheating. Use this method only if others have not helped.

7 Hardware problems: when settings don't help

If you’ve tried all the ways but the network speed is still low, the problem may be in the hardware:

• 📶 Antenna or communication module: On Xiaomi (especially budget models like Redmi) 10A or POCO M4 Pro) antenna contact or module may break down over time RF. Signs: The signal is constantly "jumping" between 3G/4G. The phone overheats when you use the mobile Internet. 0 when driving (for example, in transport).
• 🔋 Battery: A worn-out battery (capacity below 70%) may limit the performance of the communication module. → Battery → Battery status.
• 🛠️ Damage after falling: If the phone fell or got wet, the paths on the motherboard responsible for the network could be damaged.

What to do in such cases:

1. Check the phone in the service center (diagnostics of the communication module costs ~ 500-1000 rubles).
2. If the problem is in the antenna - it can be soldered (repair price: 1500-3000 rubles).
3. If the battery is to blame, replace it (the original for Xiaomi costs 1000-2500 rubles).

For a temporary solution (if repair is not an option):

• Use an external antenna. 4G/5G (plug-in OTG-adapter).
• Turn off automatic network selection and manually select 3G (if 4G/5G is unstable).
• Use Wi-Fi instead of mobile internet where possible.
