How to improve the Internet on Xiaomi Redmi: from diagnostics to advanced settings

The slow internet on Xiaomi Redmi smartphones is one of the most common problems faced by users of the budget and mid-budget models of the series. Even flagship devices sometimes “brake” in the network due to software restrictions. MIUI, In this article, we will look at 10 proven ways to improve the speed and stability of the Internet, from basic actions to hidden functions of the engineering menu.

It is important to understand that the causes of poor connection can be both external (weak signal router, overload operator network) and internal (power saving restrictions, background activity of applications). We will focus on those aspects that you can control yourself without going to the service center. If after all the manipulations the problem remains, this is an occasion to check the device for physical malfunctions (for example, damage to the antenna module).

This article is relevant for all Redmi models (including Redmi Note). 12/13, Redmi 10/11, POCO X5 etc.) working on the MIUI 12–14 Some methods are universal and suitable for other brands based on Android.

1.Diagnostics of the problem: identify the “weak link”

Before you start settings, you need to identify the source of the problem. Poor Internet speed on Xiaomi Redmi can manifest itself in different ways:

• 📶 Wi-Fi: low download speed, frequent connection breaks, inability to connect to the network.
• 📡 Mobile Internet (4G/5G): network icon is, but the pages do not load, the speed is lower 1 Mbit/s.
• ⚡ Local lags: the Internet works, but slows down only in certain applications (for example, in YouTube or Telegram).

For accurate diagnosis:

1. Check the speed through Speedtest or FAST.com. Run the test 2-3 times and write down the averages.
2. Compare the results to other devices on the same network. If you have a higher speed on your laptop or second phone, the problem is with Redmi settings.
3. Try connecting to another network (like mobile internet instead of Wi-Fi), and if the problem persists, it’s the software or hardware of the smartphone.

⚠️ Note: If the speed on Wi-Fi is below 10 Mbps and the router supports 100 Mbps+ Mbps, check the network standard. Redmi older than 2020 may not support Wi-Fi 6 (802.11ax) — In this case, the router needs to be transferred to the mode 802.11ac.

If your diagnosis shows that the problem is local (only on your Redmi), move on to the following sections, and if the speed is low on all devices, the provider or router is to blame (more on this below).

2. Wi-Fi Optimization: From Channel Selection to Hidden Settings

So, to start with the most common scenario, Wi-Fi issues, even if your Redmi sees the network, it doesn't guarantee a stable connection.

Selecting the right range (2.4 GHz vs 5 GHz)

Modern routers broadcast in two bands:

• 📶 2.4 GHz: longer range but subject to interference from other devices (microwaves, wireless headphones) ~150 Mbps.
• 🚀 5 GHz: less interference, high speed (up to 1 Gbps) but weaker passes through walls.

How to choose the best range on Xiaomi Redmi:

1. Open the Settings. → Wi-Fi.
2. Click on your network name and select Change Network.
3. If the router supports both bands, two networks with the same name will appear in the list (for example, MyWiFi_2G and MyWiFi_5G). Connect to 5 GHz for maximum speed.

⚠️ Attention: On Redmi models 9A/9C older module 5 GHz may not be available. Check the specifications of your model on the official Xiaomi website.

Manual selection of Wi-Fi channel

By default, the router chooses the channel itself, but often this leads to overlays of signals from neighboring networks.

1. Install the WiFi Analyzer app on your phone (available on Google Play).
2. Run the scan - the application will show the load of channels.
3. Select the least loaded channel (e.g. 1, 6 or 11 for 2.4 GHz).
4. Go to the router settings (usually 192.168.1.1 or 192.168.0.1) and manually set this channel.

For 5GHz, choose channels with 36-48 or 149-165 numbers (they are less loaded).

Enabling high-performance Wi-Fi mode

V MIUI There is a hidden setting that prioritizes connection speed over charge saving:

1. Go to Settings. → Wi-Fi → Additionally (or Wi-Fi settings) → Advanced settings).
2. Activate the option High Performance Wi-Fi (or Smart Wi-Fi Switching – Turn it off!).
3. Also enable Autoconnection to open networks (if you move frequently between access points).

These settings make the smartphone more actively scan the network and quickly reconnect at a cliff.

3. Mobile Internet setting: from APN prioritize

If there are problems with the mobile Internet (4G/5G), First check the basic settings:

• 📱 Make sure that the status bar is displayed 4G or 5G (not 3G or).
• 📡 Check the signal level: if it is below 2-3 sticks, the problem may be in the coverage area of the operator.
• 🔄 Reboot your smartphone – sometimes it resets “hang” network processes.

3.1. Checking and resetting of access points (APN)

Wrong settings APN (Access Point Name: A common reason for the lack of Internet access:

1. Go to Settings. → SIM-maps and mobile networks → [choose SIM] → Access points (APN).
2. If the list is empty or if there are several APN, Click Reset to Default Values.
3. For manual addition, click Add APN and enter your operator’s parameters (they can be found on the MTS, Beeline, MegaFon or MegaFon or Tele2).

Example of settings APN for MTS:

3.2. Forced selection of network standard (4G/5G)

By default, Redmi automatically selects the network standard, but sometimes it doesn't work optimally.

1. Open the Settings. → SIM-maps and mobile networks → [choose SIM] → Preferred type of network.
2. Choose. 4G (preferably 5G (If your operator supports you).
3. Turn off the auto-connection option to 2G (if any).

⚠️ Attention: On Redmi models 9/10 helio-processor G80/G90 There may be no support 5G. Check the characteristics of your model before setting up.

Resetting network settings

If nothing helps, do a complete reset of network settings:

1. Go to Settings → About Phone → Resetting → Resetting Network Settings.
2. Confirm the action – the smartphone will restart.
3. After the reboot, reset the connection to Wi-Fi and mobile network.

This method removes all stored networks and APN, So be prepared to reintroduce them.

💡

If the mobile Internet only works after a restart, check the applications in autoboot, VPN Optimizers or Optimizers block background traffic.

4. Engineering menu: hidden settings for advanced users

If standard methods don't work, you can go to the Engineering Mode, which hides parameters that the manufacturer doesn't put into the basic settings, and be careful, because the wrong changes can lead to loss of communication or network failure.

4.1 How to open the engineering menu

The method depends on the version MIUI:

• 📱 MIUI 12–14 / HyperOS: Enter the Phone app code ##4636##, then select Phone Information.
• 🔧 Older versions: Use the code ##36446337## (for MediaTek) or #808## (for Qualcomm).

If the codes don’t work, try installing the app. MTK Engineering Mode (for MediaTek processors) or Qualcomm Engineer Mode (for Snapdragon).

Optimization of network parameters

In the engineering menu, you can change:

• 📡 Network mode: Forced to enable LTE-only or NR/5G (if maintained).
• 🔄 Band Lock: Lock certain frequencies if the operator uses congested bands.
• 📶 MoSignal: Increase antenna sensitivity (relevant for low signal areas).

Example for MediaTek:

1. In the engineering menu, select MTK Settings → BandMode.
2. Choose yours. SIM-map, SIM1).
3. In the section LTE Band only keep the frequencies that your operator uses (you can find out on its website).
4. Save the settings and restart the phone.

⚠️ Warning: Sloppy changes to the engineering menu can lead to loss IMEI Before experimenting, write down your current settings or backup through Settings. → Additionally. → Backup.

5. Programmatic limitations MIUI: how to get around

MIUI It's known for aggressively optimizing background traffic, which sometimes leads to artificially slowing down the Internet:

5.1. Disabling traffic savings

Traffic Savings limits loading speed in the background:

1. Go to Settings → Connections and Sharing → Traffic Savings.
2. Turn off the Traffic Saving option.
3. In the Background Limitation section, add applications that require maximum speed to the exceptions (e.g. YouTube, Telegram).

Customization of auto-start and background activity

MIUI It blocks the background of applications, which can interfere with the stable connection, to allow background traffic:

1. Open Settings → Applications → Application Management.
2. Choose the right app (such as Chrome or Google). VK).
3. Activate options: 🔄 Auto-start 📱 Background activity 🚀 No traffic restrictions

5.3. Disabling the Smart Assistant

The Smart Assistant (or Game Turbo) function can limit the speed of the Internet in games or videos, to turn it off:

1. Go to Settings → Special features → Smart assistant.
2. Turn off the options Network Optimization and Background Limitation.

How to check:

1. Call your Redmi from another phone and walk around the room, and if you lose communications in certain places, the antenna is a problem.
2. Check if there were any physical damage (falls, moisture).

Solution: Contact a service center to diagnose an antenna cable or module. Self-repair is not recommended - the risk of damage to the board.

Processor overheating

When overheated, Redmi automatically reduces performance, including internet speed.

How to fix it:

1. Remove the cover and let the phone cool.
2. Close all background apps (especially games and video players).
3. Check the temperature through the app AIDA64 — if CPU 60°C, dust cleaning or heat paste replacement (in the service) is required).

Faulty of operation SIM-card

If you have problems with mobile internet:

• 📱 Check it out. SIM-map on another phone.
• 🔄 Clear your contacts. SIM-silk-cards (carefully!).
• 🛠️ If the slot is damaged (for example, after a fall), it must be replaced.

On the Redmi Note models 10/11 frequent problem - oxidation of contacts SIM-If you're using a card, it's because of moisture, and if you do, you can only change the module.

Alternative solutions: from VPN custom-made

If standard methods do not work, you can try non-obvious approaches.

7.1 Use. VPN circumventing operator restrictions

Some operators (especially virtual ones like Yota or Tinkoff Mobile) limit speed for certain services. VPN This can help you bypass these limitations:

1. Set it up solid. VPN-Application (e.g. ProtonVPN or Warp from Cloudflare).
2. Connect to a server in your country (for minimum delays).
3. Check the speed with the Speedtest.

If the speed went up, the problem was the operator's limitations: VPN It may be slowing down the connection itself due to encryption.

7.2. Custom firmware (for advanced users)

Stock-stock MIUI It's known for its brakes and its limitations. AOSP (Like LineageOS or Pixel Experience:

• 🚀 No background traffic restrictions.
• 🔧 More settings to optimize the network.
• 📱 Less trash in the system.

Risks:

• ⚠️ Loss of guarantee.
• 🔄 Possible bugs (e.g., non-functioning) NFC camera).
• 📱 Installation difficulty (requires unlocking the loader).

If you decide on custom firmware, follow the instructions from the forum XDA Developers or 4PDA for your model.

Alternatives DNS-server

Sometimes the slow functioning of the Internet is associated with DNS-ISP servers, to change them:

1. Install the app DNS Changer or 1.1.1.1 from Cloudflare.
2. Choose. DNS-server: 🌍 1.1.1.1 (Cloudflare) - fast and safe. 🌐 8.8.8.8 (Google DNS) — Stable, but can slow down in Russia. 🇷🇺 77.88.8.8 (Yandex DNS) — optimized for Runet.

Check the speed of loading pages.

This method is especially effective if it only slows down the browser or specific sites.

8 Prevention: How to avoid problems in the future

To avoid running into slow internet on Redmi, follow the following simple rules:

• 🔄 Regularly update the software: in new versions MIUI Frequently fix network bugs. Check for updates in Settings → The phone. → Updating the system.
