How to turn on top speed of the Internet on Xiaomi devices: Step-by-step guide

Have you noticed that the Internet on your Xiaomi is slower than it should be? Pages load for a long time, video slows down, and online games are lagging - even with a stable connection to Wi-Fi or mobile network? The problem may lie not in the provider, but in the settings of the device itself. In this article, we will discuss 7 proven ways to increase Internet speed on Xiaomi smartphones, tablets and TV sets, including hidden features MIUI and technical nuances of network operation.

It's important to understand that the speed of the Internet depends on many factors, from the load of the provider's channel to the hardware limitations of your gadget. 80% In some cases, users lose 30-50% We will focus on unique methods for Xiaomi devices that you will not find in standard instructions, such as optimizing the operation of the module. MTK Wireless on MediaTek processors or forced channel aggregation on Qualcomm Snapdragon.

The instructions in the article are relevant for all modern Xiaomi, Redmi and other devices. POCO (including models 2023-2026 years MIUI 14/15), and also for Xiaomi TV And Mi Box. If you use custom firmware, some of the tips may not work because of the modified system files.

1.Diagnostics of the current speed: how to understand where the connection is inhibiting

Before you optimize your settings, you need to identify a bottleneck. Slow Internet can be caused by:

• 📶 Problems on the provider side (speed limitation, network congestion)
• 📱 Hardware limitations of the device (weak Wi-Fi module, outdated communication standard)
• ⚙️ Software settings (background processes, limitations) MIUI, wrong DNS)
• 🔌 External interference (large number of connected devices, thick walls, neighboring networks on the same frequency)

For accurate diagnosis:

1. Connect to the same network from another device (like a laptop), and if the speed is normal, your Xiaomi is a problem.
2. Check the speed through Speedtest or FAST.com. Run the test 3 times and record the average result.
3. Compare the metrics when connecting via Wi-Fi and mobile network (if any) SIM-More than 2 times the difference? So the problem is the wireless network settings.

Notice the ping parameter in the test results, if it is greater than 100 ms, it may indicate:

• 🔄 Router Overload (try restarting the router)
• 📡 Interference on the air (change the Wi-Fi channel in the router settings)
• 🛡️ Active. VPN Firewall (turn them off during the test)

⚠️ Note: If the speed on Wi-Fi on Xiaomi is lower than on other devices on the same network, but the mobile Internet works normally - the problem is precisely in the settings of the wireless module of the smartphone.

Optimizing Wi-Fi Connection: Choosing Frequency, Channel, and Standard

Xiaomi devices often connect to the network by default on a frequency 2.4 GHz, though 5 GHz can give in 2-3 This is how you fix it:

Go to Settings. → Wi-Fi, tap your network name and select Change Network. If there's a frequency range or Band option, set it:

• 📶 5 GHz – for maximum speed (but shorter range)
• 📶 2.4 GHz – if the signal is weak or needs to be connected from afar
• 📶 Auto – if the router supports Wi-Fi 6 (802.11ax) He can choose the best range for himself.

On some models (such as the Xiaomi 13 Pro or Redmi Note 12), this option is hidden to unlock it:

1. Enter the dialer code: ##4636##
2. Go to the Wi-Fi information tab
3. Press the Wi-Fi frequency band and select the desired range.

Another important parameter is the width of the channel. In the router settings (not the phone!) set:

• 📶 For 2.4 GHz: 20/40 MHz (automatically)
• 📶 For 5 GHz: 80 MHz (if the router supports)

⚠️ Attention: If, after switching to 5 GHz communication has become unstable, check if your router supports this range.Some budget models (e.g. Xiaomi Mi Router) 3G) work only 2.4 GHz. Also make sure that the router settings are on mode. 802.11a/n/ac/ax (not 802.11b/g/n).

3.Tune in. DNS: How to speed up the loading of sites in 2 times

Xiaomi is using the default DNS-Your ISP's servers, which are often slow, and they're replaced by public ones. DNS It can speed up the opening of pages on 30-100%.

Instructions for changing the DNS:

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.quad9.net (Quad9 malware-protected)

Save the settings and restart the device

Open the browser in incognito mode

Run a test on [DNS Leak Test](https://www.dnsleaktest.com)

Make sure that the selected one is displayed DNS (Google/Cloudflare)

Check the speed of loading sites (for example, YouTube.com)-->

For advanced users: if you are using ADB, can be forced DNS for all connections by team:

adb shell settings put global private_dns_mode hostname


adb shell settings put global private_dns_specifier dns.google

The effect of the shift DNS particularly noticeable:

• 🌍 Access to foreign websites (YouTube, Netflix, Steam)
• 🛡️ Use of VPN (decreases when connected)
• 📱 Working with applications that often access servers (Telegram, Instagram)

💡

After the shift DNS Some sites have stopped opening (for example, banking), return the provider’s settings or try Cloudflare (1.1.1.1) – it is less likely to be blocked.

4. Disabling background processes and limiting traffic for applications

MIUI It's known for aggressively optimizing background processes, but sometimes it works against the user. For example, auto-update apps or synchronize clouds can eat up to 50% of the channel at peak moments.

How to limit background traffic:

1. Go to Settings → Applications → Application Management
2. Select an app (e.g. Google Play Store or Mi Cloud)
3. Tap Mobile Data and Wi-Fi
4. Turn off the options: 🔄 Background data 📥 Autoboot (for media) ☁️ Autosynchronization

For a global limitation:

• 📵 Enable Traffic Saving Mode in Settings → Connections → Saving traffic
• 🛑 Disallow Auto-Running Applications: Settings → Battery and productivity → Autostart control
• 🔄 Turn off automatic download of updates MIUI: Settings → The phone. → Updating the system → ⚙️ → Auto-update

Pay special attention to these “gluttonous” applications:

⚠️ Note: If you are using Xiaomi TV or Mi Box, be sure to turn off automatic app updates in Settings → Annexes → Auto-update: These devices often update firmware and software in the background, which can take up to 70% of the channel at night.

5. Reset network settings and update firmware

If previous methods have not worked, the problem may be system settings. Network resets often solve problems with:

• 🔌 Permanent breaks in connection
• 📉 Abrupt speed drawdowns
• 🔒 Inability to connect to some networks

How to reset your network settings:

1. Go to Settings. → Connections and sharing → Resetting Wi-Fi, Mobile Network and Bluetooth
2. Confirm the action (you will need to enter a pattern lock or PIN)
3. Reset the device

After discharge:

• 🔄 Connect to Wi-Fi and check the speed.
• 📱 Update the firmware: Settings → The phone. → Updating the system
• 🔧 If the problem persists, check if the beta version is installed. MIUI (They often contain bugs)

For Xiaomi. TV and the Mi Box procedure is similar:

1. Settings → The Internet and the Internet → Resetting network settings
2. After reset, go to Settings. → About the device → Updating the system

💡

Network reset removes all stored Wi-Fi passwords and associated Bluetooth devices.

If the speed has dropped after the update, it is possible that the new version will be MIUI It contains bugs:

• 📉 Reverse to the previous version via Fastboot (instructions on xiaomi.eu)
• 🛠️ Install custom firmware (e.g. Pixel Experience or LineageOS)
• 📡 Check if new Wi-Fi settings (such as Wi-Fi Direct or Wi-Fi Display) have appeared that may conflict)

6. Advanced settings for experienced users

If standard methods fail, you can try deeper customizations, which require root rights or access to an engineering menu.

Method 1: Enabling channel aggregation (for Qualcomm processors)

On Snapdragon chips (e.g. Xiaomi 12 Pro, POCO F4) can be forced to LTE CA (Carrier Aggregation, which increases the speed of mobile Internet:

adb shell


su




echo "1" > /sys/module/lpm_levels/parameters/sleep_disabled




setprop persist.radio.lte_cphy true




setprop persist.radio.calls.on.ims true

Method 2: Optimization MTK Wireless (for MediaTek processors)

On devices with chips MediaTek (Redmi Note 11, POCO M4 Pro can improve the stability of Wi-Fi:

adb shell


su




iwpriv wlan0 set_mib power=0




iwpriv wlan0 set_mib txpwr=100

Method 3: Change of parameters TCP/IP

To reduce ping and increase download speed:

adb shell settings put global captive_portal_detection_enabled 0


adb shell settings put global captive_portal_server none




adb shell settings put global http_proxy :0

These methods have the greatest effect on:

• 🎮 Online games (ping decreases)
• 📥 Torrents and file sharing (upload speed increases)
• 📺 Streaming video 4K/8K (remove inhibition)

⚠️ Warning: Incorrect use of ADB-command may result in loss of warranty or unstable operation of the device.Before experimenting, back up through Settings → Additionally. → Backup and reset. If the device stopped turning on after the changes, you will need to flash it through Fastboot.

7. Alternative ways to speed up the Internet

If all of the above methods have not worked, consider these options:

1. Using an external Wi-Fi adapter (for Xiaomi) TV/Mi Box)

Built-in Wi-Fi modules in TV set-top boxes are often weaker than in smartphones. USB External adapter (recommended models:

• 📡 TP-Link Archer T2U Plus (Wi-Fi 5, up to 867 Mbps)
• 📡 ASUS USB-AC68 (Wi-Fi 6, up to 1.3 Gbps)
• 📡 Xiaomi Wi-Fi Amplifier Pro 2 (to enhance the signal)

2. Connection via Ethernet adapter

For smartphones with support USB OTG (Most of the Xiaomi models):

• 🔌 Buy an adapter. USB-C/RJ45 (for example, UGREEN Ethernet Adapter)
• 🔌 Connect the router cable directly to your phone
• 🔌 B Settings → Ethernet select Static IP and provide data from the provider

3. Set up QoS on the router

If you have access to the router settings:

• 📡 Enable QoS (Quality of Service)
• 📡 Set a priority for MAC-Addresses of your Xiaomi
• 📡 Limit traffic to other devices (such as smart devices) TV or IP-camera)

4. Change of mobile operator

If you have a problem with mobile internet, check the coverage of operators in your area:

• 📶 MTS - the best coverage in cities
• 📶 Tele2 is cheap traffic, but weak signal in villages
• 📶 Beeline – Medium quality, but often profitable rates
• 📶 Yota is unlimited internet, but speed limit after 20GB

Use the service 2ip.ru/mobile-coverage, Compare the coverage of operators at your address.
