How to increase the speed of the Internet on the phone Xiaomi Redmi: from simple settings to hidden features MIUI

Slow internet on Xiaomi Redmi is a problem faced by every second owner of this line of smartphones. The reasons can lie in the settings of the device itself, and in the peculiarities of the network. 4G/5G Unlike iPhones or Samsung flagships, Redmi phones often suffer from aggressive background optimization. MIUI, It's a system that restricts network traffic "to save battery life," but the good news is: 90% Problems are solved software without contacting the service center.

In this article, we will discuss specific methods for all Redmi models (from Redmi Note). 4X redmi 13 Pro+), This includes the developer's hidden settings, the choice of optimal frequencies, and even hardware solutions for the most "exploited" cases. MIUI 14/15, Xiaomi has introduced new traffic management algorithms, all of which are tested on real devices, without water or abstract tips.

Before you start settings, check the basic speed of your Internet.

1. Turn off Wi-Fi and leave only the mobile network (or vice versa).
2. Run the speed test on Speedtest or FAST.com.
3. Write down the ping, download and return metrics – they will be useful for comparison after optimization.

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

If you have slow mobile Internet, the problem most often is that you have wrong network settings or carrier restrictions, and let's start with the simplest one: choosing the right network mode.

Xiaomi Redmi is often installed as default mode 4G/3G/2G (Auto) which leads to "sticking" on slow networks 3G or 2G In a weak signal, forced choice is only 4G (or 5G, If supported, it can increase the speed of 30-70%.

How to change the network mode:

1. Go to Settings. → SIM-maps and mobile networks.
2. Choose yours. SIM-card (if there are several).
3. Click Network Type and install Only 4G (or 5G/4G/3G/2G support-model 5G).
4. When you change, restart your phone.

💡

On the Redmi Note. 12 Pro+ The newer menu may not have the option 4G. In this case, use the preference. 5G — It will make your phone ignore it. 3G/2G.

Additional settings for 4G/5G

• 📶 Enable VoLTE (voice through) 4G): Settings → SIM-map → Challenge 4G. This will free up the network’s resources for data.
• 🔄 Turn off automatic network selection: manually select operator in Settings → Mobile network → Network operators.

2. set up Wi-Fi for maximum speed

If you have a Wi-Fi problem, check your router's real speed first, connect your phone to the same network as your computer, and compare it. If you have a high speed on your PC and a low speed on your Redmi, you're to blame for your smartphone settings.

The most common reason for brakes is automatic Wi-Fi frequency selection. Many routers broadcast simultaneously at 2.4 GHz (long but slow range) and 5 GHz (fast but with less coverage area). By default, Xiaomi connects to 2.4 GHz, even if 5 GHz is available.

How to forcefully connect to 5 GHz:

1. Open the Settings. → Wi-Fi.
2. Click on your network name and select Change Network.
3. In the Frequency field (if any) set 5 GHz.
4. If there is no option, rename it. SSID Your router, adding at the end of the _5G (for example, MyWiFi_5G).

On the Redmi Note 11 Pro and older MIUI 14+ The manual frequency selection option is hidden. To return it, turn off the Intelligent Connection in the Wi-Fi settings.

Optimization DNS and MTU

Wrong settings DNS slow down 10-40%. By default, operators and providers use their DNS-servers that are not always optimal.

How to change the DNS to Xiaomi Redmi:

1. Go to Settings. → Wi-Fi, click on your network.
2. Select Additional → Settings IP and set up a static.
3. In the fields DNS 1 and DNS 2 Enter: 1.1.1.1 (Cloudflare) 8.8.8.8 (Google)
4. Save and reconnect to the network.

Set up static IP|Change. DNS either 1.1.1.1 or 8.8.8.8|Deactivate "Intelligent connection"|Rename SSID 5 GHz|Check the speed after the changes-->

3. Hidden developer settings to speed up the Internet

Xiaomi Redmi has a hidden menu for developers where you can fine-tune networking, which is not visible in standard settings, but has a huge impact on speed.

How to turn on the developer mode:

1. Go to Settings. → The phone.
2. Click 7 times on the MIUI version (you will be notified "You became a developer").
3. Return to the main settings menu and a new section for developers will appear.

Now we turn to the key settings:

• 📡 Turn off background restriction: For developers → Network → Limit background traffic → Otknock..
• 🔧 Enable aggressive Wi-Fi switching: For developers → Network → Aggressive switching of Wi-Fi to mobile network → On (useful for weak signal).
• 🚀 Increase the buffer TCP: For developers → Network → Buffer size TCP → Set 1024 KB (by default 512 KB).
• 🔄 Turn off automatic synchronization: For developers → Network → Autosynchronization → Otknock..

💡

Setting up Aggressive Wi-Fi switching is useful if you have unstable Wi-Fi.The phone will move to the mobile network faster when the connection is cut, but it will increase traffic consumption.

Warning: Not all options in the developer menu are safe, such as changing the settings Max. number of Wi-Fi connections or Scan Wi-Fi in sleep mode can lead to loss of connection or increased battery consumption.

⚠️ Note: Redmi with MediaTek processors (e.g. Redmi Note 11, Redmi) 10C) buffering TCP If the phone gets hot, return the value to 512 KB.
