How to speed up the Internet on the phone Xiaomi Redmi: from simple settings to hidden chips MIUI

Your Xiaomi Redmi slows down when loading pages, video is constantly buffered, and the Internet speed on your phone is several times lower than on other devices? The problem is familiar to most owners of smartphones in this line - even the flagship models of the Redmi Note 12 Pro+ or Redmi K60 Sometimes they suffer from lags on the network, not only because of the operators, but also because of hidden settings. MIUI, background processes, as well as hardware limitations of budget chipsets from Qualcomm and MediaTek.

In this article, we will discuss 12 proven ways to speed up the Internet on Xiaomi Redmi – from basic (change DNS, clear cache) to advanced (set up APN, turn off IPv6, optimize the kernel). All methods are tested on the Redmi 10/11/12/13 series, POCO X3/X4/X5 and Redmi K50/K60 with MIUI 13/14 firmware and HyperOS. No root or complex manipulations – only working solutions with step-by-step instructions.

Before you start, check your real internet speed with Speedtest by Ookla or nPerf. Run the test on your phone and compare it to other devices on the same network. If the difference is greater than 30%, the problem is exactly with Redmi settings.

1. DNS change: why standard servers are slowing down the Internet

Xiaomi Redmi is using the default DNS-Your operator's servers (MTS, Beeline, Megaphone, Tele2), which are often overloaded or far from your region. This increases ping and reduces download speed. DNS (Google, Cloudflare, and AdGuard can speed up the internet by 20 to 50 percent%.

How to change the DNS to Xiaomi Redmi:

• 📱 Open the Settings. → SIM-maps and mobile networks.
• 🔗 Choose yours. SIM-map → Access points (APN).
• 🖥️ Tap on the current profile (for example, Internet.mts.ru) → DNS 1 and DNS 2.
• 🔧 Enter addresses: Google DNS: 8.8.8.8 and 8.8.4.4 Cloudflare: 1.1.1.1 and 1.0.0.1 AdGuard (blocks ads): 94.140.14.14 and 94.140.15.15
• 💾 Save the settings and restart the phone.

To check the effectiveness, use the DNS Changer app (available on Google Play), which tests the speed of different DNSs in real time. If the speed has not increased after changing the servers, return the standard settings and move to the next method.

💡

After the shift DNS Some sites (e.g., banking sites) have stopped opening, and some sites have temporarily returned the operator's standard servers. DNS for security reasons.

2. APN optimization: hidden mobile internet settings

APN (Access Point Name) is the gateway through which your Redmi connects to the carrier's Internet. Wrong APN settings can limit speed even if the network signal is full. Operators rarely update these settings automatically, so they have to be manually edited.

How to set up an APN for maximum speed:

• 📡 Go to Settings. → SIM-maps and mobile networks → [yours SIM] → Access points (APN).
• ➕ Click Add Access Point and enter the settings for your operator (see table below).
• 🔄 Save your profile and select it active (check next to the name).
• 🔄 Reboot the phone.

If your operator is not in the table, look for the current APN settings on its official website (Setting up the Internet section). After changing the parameters, check the speed - sometimes the difference reaches 10-15 Mbps.

IPv6 shutdown: Why a new protocol could slow down the internet

IPv6 is a modern Internet protocol that was supposed to replace the legacy IPv4. However, many Russian carriers and sites are still not optimized for IPv6, which leads to delays and packet loss. At Xiaomi Redmi, this protocol is often turned on by default, even if it is not needed.

How to disable IPv6 on Xiaomi:

1. 📱 Go to Settings. → SIM-maps and mobile networks → [yours SIM] → Access points (APN).
2. 🖥️ Select the current one. APN → field APN.
3. ❌ Take the tick off IPv6 (Just leave it. IPv4).
4. 💾 Save and restart the phone.

To check the effectiveness, use the command in Terminal Emulator (install from Google Play):

ping -6 ya.ru

If the ping is not passing or is too high (over 100 ms), the IPv6 shutdown is justified. If the speed has not changed, return the settings back.

💡

Shutdown IPv6 This is especially true for users of MegaFon and Tele2 – these operators often have problems with routing. IPv6-traffic.

4.Cache and background cleanup: why MIUI is stealing traffic

MIUI is known for its “gluttony”: the system constantly synchronizes data, updates widgets and keeps background processes in memory, which not only consumes the battery, but also loads the network, reducing the speed of basic tasks (for example, watching videos or downloading files).

How to Free Your Network from Unnecessary Traffic:

• 🧹 Cache Clearing: Go to Settings → Annexes → App management. sort by cache size and clear data from Google Play Services, Mi Video, Browser.
• ⚡ Disabling Auto Updates: In Google Play: Settings → Auto-update of applications → Only through Wi-Fi. In the Mi App Store: Settings → Auto-update → Off.
• 🚫 Background Traffic Limitation: C Settings → SIM-maps and mobile networks → Transfer of data → Background traffic disable unnecessary applications.

For deep cleaning, use the SD Maid app (requires root for full functionality) or the built-in Security → Cleanup utility in MIUI. After cleaning, the speed can increase by 10-30%, especially if the phone has not restarted for several days before.

5. Network Mode Setup: 4G vs 5G vs "3G Only"

Many Xiaomi Redmi users mistakenly believe that 5G is always faster than 4G. In practice, it all depends on the load of the base station, the distance to it and the signal quality. Sometimes forced switching to 4G Only (LTE) or even 3G Only gives a better speed than automatic mode.

How to choose the optimal network mode:

• 📶 Go to Settings. → SIM-maps and mobile networks → [yours SIM] → Preferred type of network.
• 🔄 Try the following modes in turn (after each, test the speed in Speedtest): 5G/4G/3G/2G (Auto) - standard mode. 4G (LTE) — quicker 5G In densely built cities. 3G — It can help in rural areas or basements.
• 📊 Remember the mode in which the speed is maximum, and use it constantly.

For Redmi models with support 5G (For example, Redmi Note 11T Pro, Redmi K50) usefully SA-Standardone if the operator does not support it:

##4636## → Phone Information → Install your preferred network type → NR/LTE/TD-SCDMA/GSM (instead of NR only)

💡

If after the network change, the phone stopped catching the network at all, return the settings to the Auto and restart the device. In rare cases, manual adjustment can lead to loss of connection.

6.Wi-Fi Optimization: Why Your Router is the One That Stops Your Redmi

If speed issues only occur in Wi-Fi and mobile internet is working fine, either the router or the network settings on the phone are to blame. Xiaomi Redmi (especially models with MediaTek Helio G) often conflict with some Wi-Fi standards, such as 802.11ac or Wi-Fi 6.

How to speed up Wi-Fi on Redmi:

• 📶 Switch to 5GHz Range (if the router supports): In the router settings, select 5GHz and set the channel width of 40 MHz (instead of 80 MHz, which may be unstable). → Wi-Fi → [your network] → Range. → 5 GHz.
• 🔧 Turn off Wi-Fi Assist (automatic switch to mobile data): Go to Settings → Wi-Fi → Additionally. → Wi-Fi Assist and disable the function.
• 🔄 Change. DNS for Wi-Fi: In network settings (long tap on Wi-Fi name) → Change the network) write 1.1.1.1 in the field DNS.

If the speed is still low, try forgetting the network and reconnecting:

1. 🔗 Settings → Wi-Fi → long-press → Delete.
2. 🔄 Restart the router (turn off power for 30 seconds).
3. 📱 Connect to the network again and enter the password.

💡

If you have a dual-band router, give 2.4 GHz and 5 GHz different names (SSID) to Redmi to select the optimal range automatically.

7. Advanced Methods: Engineering Menu and Core Optimization

If standard methods don’t work, it’s time to look into the engineering menu and hidden MIUI settings, which require caution but can give you speeds of up to 30-40%.

How to speed up the Internet through the Engineering Menu:

• 📞 Enter the code: ##4636### and select Phone Information.
• 🔄 In the Set your preferred network type section, try the following combinations (test the speed after each one): LTE only - compulsory 4G. LTE/TD-SCDMA/GSM Auto - optimal for MTS/MegaFon. NR/LTE/TD-SCDMA/GSM — for 5G-device.
• 📡 In the Wi-Fi information section, check the Wi-Fi frequency. If the 2.4 GHz value is low, switch to 5 GHz in the router settings.

For models with Qualcomm Snapdragon chipsets (such as the Redmi Note 12 Pro+), you can also optimize the network core using the Network Signal Guru app (requires root), which allows you to manually select the base station with the best signal.

8 Hardware Restrictions: When the CPU or modem is to blame

If you’ve tried all the methods, but the internet speed on Xiaomi Redmi is still low, the problem may be the hardware:

• 📉 Budget chipsets (Helio) G35/G80, Snapdragon 4xx) physically unable to handle high speeds 4G/5G.
• 📡 Weak modem (for example, in Redmi) 9A or Redmi 10A) Limits speeds to 50–100 Mbps even under ideal conditions.
• 🔋 Overheating of the processor due to poor thermal paste (relevant for Redmi Note 10 Pro and older).

How to check hardware limitations:

1. 🔍 Find out the model of your Redmi chipset in Settings → The phone. → Characteristics.
2. 📊 See the maximum modem speed for your CPU (see table below).
3. 🌡️ Check the temperature of the processor using AIDA64. If it's above 60.°C under load - thermopaste replacement is required.

If your chipset is objectively weak, the only way to speed up the internet is to switch to a more powerful modem model (e.g. Redmi Note 12 Pro+ with Dimensity 1080 or Redmi K60 with Snapdragon 8+ Gen1).

💡

If you are not ready to change your phone, try using an external phone. USB-modem (e.g. Huawei) E3372) through OTG-This bypasses the limitations of the Redmi built-in modem.
