How to Maximize Wi-Fi Speed ​​on a Xiaomi Phone: A Step-by-Step Guide

Slow internet on Xiaomi It's especially annoying when other devices on the same network work without problems. The cause may lie in both the smartphone's settings and firmware features. MIUIIn this article we will discuss 7 proven methodsthat will help increase Wi-Fi speed on any phone Xiaomi - from budget Redmi to the flagship Mi And POCO.

It's important to understand that connection speed depends on a variety of factors, from the router standard to the bandwidth. We'll focus on those parameters that can be optimized. directly on the phone, without purchasing new hardware. Some methods require administrator rights, but most are available to any user.

If you're still unsatisfied with your speed after trying all these tips, the problem may be with your ISP or router. In this case, you should check the speed on other devices and contact technical support.

1. Optimize Wi-Fi settings in MIUI

Firmware MIUI hides several useful options that are disabled by default. Enabling them can significantly improve connection stability and speed. Let's start with the basic settings:

Go to Settings → Wi-Fi, tap on your network name and select Change networkHere, pay attention to three key parameters:

• 🔄 Auto-connection: Enable this if your phone frequently loses network connection after sleep. This will make the device more actively search for familiar access points.
• 📶 Wi-Fi Performance Mode: activate in Settings → Wi-Fi → AdvancedThis option prioritizes speed over battery saving.
• 🔒 Security type: if your router supports WPA3, select it instead WPA2 - this reduces delays during authorization.

Pay special attention to the parameter Frequency bandOn modern routers it is better to choose 5 GHz instead of 2.4 GHz, if your Xiaomi supports this range. To check compatibility, go to Settings → About phone → Full specifications → Networks and find the line Wi-Fi standards. If it is indicated there 802.11ac or 802.11ax, your device works with 5 GHz.

Don't forget about the function Intelligent switching (Smart Switch) in some models XiaomiShe automatically chooses between 2.4 GHz And 5 GHz depending on the conditions. To enable it, go to Settings → Wi-Fi → Advanced → Smart Switch.

2. Reset network settings and cache

Over time, temporary files and incorrect configurations accumulate in the system, which can slow down Wi-Fi performance. A complete reset of network settings often resolves the issue without any additional steps.

Follow these steps:

1. Open Settings → Connections and Sharing → Reset Wi-Fi, mobile network, and Bluetooth settings.
2. Confirm the action. The phone will reboot, and all saved networks will be deleted.
3. After rebooting, reconnect to Wi-Fi by entering the password.

If the reset does not help, clear the cache of system applications responsible for the network:

• 📱 Go to Settings → Applications → Manage applications.
• 🔍 Find Settings (the app with the gear icon) and select Storage → Clear Cache.
• 🔄 Repeat for apps Wi-Fi And Google Play Services.

After these steps, the speed should stabilize. If the problem persists, proceed to the next methods.

3. Change Wi-Fi regional settings

One of the little known tricks for Xiaomi — changing regional Wi-Fi restrictions. By default, the phone may not use all available channels due to local regulations. Changing the region USA or Europe often opens access to additional channels 5 GHz, which reduces network congestion.

To do this:

1. Activate developer modeby pressing 7 times on MIUI version V Settings → About phone.
2. Return to Settings → Advanced → For developers.
3. Find the item Wi-Fi Region (or Wi-Fi country code) and select US.
4. Restart your phone.

After rebooting, check the available networks. If previously 5 GHz If it wasn't showing up, it should now. Please note: This method may violate local radio frequency laws. Use at your own risk.

What happens if I select a non-existent region?

If you enter an incorrect country code (for example, XX), your phone may lose the ability to connect to some networks. In this case, reset your Wi-Fi settings or return to the original region.

For models POCO and new ones Redmi The path may differ. If you don't find the item Wi-Fi Region, try using the ADB command:

adb shell settings put global wifi_country_code US

4. DNS and MTU optimization

Incorrect settings DNS And MTU can significantly slow down page loading, even if speed tests show high results. We optimize these parameters manually.

First, let's change your DNS. By default, providers often use slow servers. We recommend switching to:

• 🌍 1.1.1.1 (Cloudflare) - fast and secure;
• 🌐 8.8.8.8 (Google) - reliable, but may collect data;
• 🛡️ 9.9.9.9 (Quad9) - with filtering of malicious websites.

To change DNS to Xiaomi:

1. Press and hold your finger on the name of your network in Settings → Wi-Fi.
2. Select Change Network → Advanced → IP Settings.
3. Install Custom and enter the selected DNS in the fields DNS 1 And DNS 2.

Now let's optimize MTU (Maximum Transmission Unit). An incorrect value leads to packet fragmentation and loss of speed. For most networks, the optimal MTU is 1472To change it:

1. Connect to Wi-Fi.
2. Install the application MTU Tools from Google Play.
3. Run the test and apply the recommended value.

5. Disable background processes and save traffic

MIUI aggressively optimizes background processes, which sometimes leads to artificially limited Wi-Fi speed. This is especially noticeable on budget models. Redmi, where the system tries to save resources.

The first thing you need to do is turn it off traffic saving:

1. Go to Settings → Connections and Sharing → Data Saver.
2. Turn off the slider Saving Wi-Fi traffic.
3. In the section Background limitation add frequently used applications to exceptions (for example, YouTube, Telegram).

Next, we will limit the background activity of system applications:

• 📵 Open Settings → Applications → Manage applications.
• 🔍 Find Google Play Services, Mi Video, Mi Browser and other pre-installed programs.
• 🚫 For each, select Limit background activity And Disable autostart.

On Xiaomi models with Snapdragon 4xx and 6xx processors (e.g., Redmi Note 10, POCO M3), background optimization is especially aggressive. After disabling restrictions, background download speeds can increase by 30-50%.

If after these steps some applications stop updating in the background (for example, instant messengers), add them to the exceptions in the section Settings → Battery → Battery optimization.

6. Updating the firmware and Wi-Fi kernel

Slow Wi-Fi is sometimes caused by firmware bugs or outdated module drivers. Xiaomi regularly releases updates that fix such issues. Check your version is up to date. MIUI:

Go to Settings → About phone → System updateIf a new version is available, install it. Please note two points:

• 🔄 Stable branch (Stable) suitable for everyday use;
• 🧪 Developer (Developer) may contain recent fixes, but is less stable;
• 📡 Regional firmware: For best Wi-Fi compatibility, choose Global or EEA.

If the update didn't help, try manually re-flashing the firmware. Wi-Fi moduleTo do this:

1. Download the latest firmware version for your model from the official website. Xiaomi.
2. Go to Settings → About phone, tap 10 times on Kernel version.
3. Select the downloaded file and wait for the installation to complete.
