How to turn on the maximum speed of the Internet on Xiaomi Redmi: from settings to upgrade

Have you noticed that the Internet on your Xiaomi Redmi is slower than it should be? Pages loaded for eternity, video is constantly “hanging” on buffering, and online games are laid at the most critical moment? The problem is not always the tariff of the mobile operator or Wi-Fi provider. Often the settings of the smartphone, background processes or even hardware limitations are to blame. In this article, we will discuss 7 proven ways to “overclock” the Internet on Redmi – from basic settings to advanced tricks that are silent even in service centers.

It's important to understand that the speed of the Internet depends on a variety of factors: this is the type of connection (3G/4G/5G or Wi-Fi 5/6), and the state of the operator's network, and the loading of the channel, and even the temperature of the smartphone processor. We will focus on those aspects that you can control yourself without consulting specialists. Most methods are universal for all Redmi models (from Redmi 9A to Redmi Note 12 Pro+), but where necessary, we will specify the nuances for specific devices.

Before you start setting up, check your current Internet speed with services like Speedtest or FAST.com. Write down the results so you can objectively assess the effectiveness of each method. And remember, if your tariff is limited (for example, 10 Mbps), no settings will exceed this limit.

1. Optimization of mobile Internet settings (4G/5G)

If you're connected to a mobile network, the first thing to do is check the network mode, and many users don't even realize that their Xiaomi Redmi defaults to 3G/4G (auto), even though it could be using 4G+ or 5G (if supported).

Open the Settings. → SIM-maps and mobile networks → [Yours. SIM-map] → Network type. Here you'll see a few options:

• 📶 2G/3G/4G (The most lazy mode: the smartphone chooses the network itself, but often gets stuck on the network. 3G, even 4G available.
• 📶 4G (recommended - enforced includes only LTE. Suitable for most users.
• 📶 4G+/5G — If your Redmi supports you 5G (For example, Redmi Note 11T Pro or newer, select this item. In some regions 5G maybe faster 4G into 2–3 once.
• 📶 Only 3G or 2G — Use only in case of problems with the coating 4G/5G.

After the change of mode, restart your smartphone. If the speed has not increased, check the frequency band used by your operator. For example, MTS and Beeline in Russia actively use the Band 3 (1800 MHz) and Band 7 (2600 MHz) band for 4G. Make sure that your Redmi supports these frequencies (see FrequencyCheck website).

⚠️ Note: Some Redmi models (e.g. Redmi) 9C or Redmi 10A) The network type menu may not have an option 5G, Even if the smartphone technically supports this standard, it's a firmware restriction. MIUI. The solution is to upgrade to the latest version or use custom firmware (more in section 6).

2. set up Wi-Fi for maximum speed

If you're connected to Wi-Fi, but the speed is not good, the problem may be the wrong settings on the router or the smartphone itself.

Go to Settings → Wi-Fi, tap the name of your network and check:

• 🔄 Frequency Range: Modern routers operate on two bands — 2.4 GHz and 5 GHz: The first is more long-range, but overloaded (especially in apartment buildings); the second is faster and more stable. 5 GHz, connect to the network with the suffix _5G (for example, MyWiFi_5G).
• 📶 Channel width: In router settings (not smartphone!), set a 40 MHz channel width for 2.4 GHz and 80 MHz for 5 GHz.
• 🔒 Type of security: Use WPA2-PSK or WPA3. Obsolete. WEP Not only is it unsafe, it also slows down the connection.

If the speed is still low after this manipulation, try changing your DNS. Your provider's default DNS is used, which can be overloaded. Go to Settings → Wi-Fi → [Your network] → Change the network → Additional settings → IP settings and select Static. In the DNS 1 and DNS 2 fields, type:

1.1.1.1


8.8.8.8

These are the DNS from Cloudflare and Google, which are usually faster.

Make sure the router supports 5GHz

Check the distance to the router (no more than 10 meters for 5 GHz)

Disable VPN (if used)

Reboot the router and smartphone-->

3. Disabling background processes and software optimization

Even if your tariff or Wi-Fi is fast, background apps can eat up traffic and slow down the Internet, such as automatically updating apps on Google Play, syncing cloud services (Mi Cloud, Google Drive) or advertising SDKs in games.

Open Settings → Applications → Application Management and analyze the list according to the following criteria:

• 📥 Auto Update: Go to Google Play, tap on the avatar → Settings → Network settings → Auto Update Apps and select Only via Wi-Fi or Do Not Update Automatically.
• ☁️ Synchronization: In Settings → Accounts and syncs: Turn off automatic sync for unnecessary services (e.g. Mi Cloud, unless you use Xiaomi backups).
• 🚫 Background Limitation: In the settings of each application (e.g. Facebook, Instagram), find the Data Use option and enable Limit Background Activity.

Pay special attention to the power saving mode. In MIUI, it defaults to limit network performance to save battery power. Go to Settings → Battery and Performance → Energy saving mode and select Performance (or Balanced if the former goes too fast).

💡

If the speed increased after switching off the background processes, but after a while it fell again, check your smartphone for viruses using Malwarebytes or Dr.Web Light. Some malware masquerades as system processes and steal traffic.

4. Reset network settings and update firmware

If previous methods have failed, the problem may be network configuration conflicts or outdated software, starting with the most radical but effective way to reset network parameters.

Go to Settings → About Phone → Settings Reset → Resetting Wi-Fi, mobile Internet and Bluetooth settings. This process will delete all stored networks and passwords, but return network settings to factory values.

1. Connect again to Wi-Fi or mobile network.
2. Run a speed test.
3. If the speed has increased, reset the networks (see sections 1 and 2).

If the reset didn't work, check the firmware version. Outdated software may contain bugs that affect Internet speed. Update MIUI to the latest version:

1. Open Settings → About the phone → System update.
2. Click Check for updates.
3. If a new version is available, download and install it.

⚠️ Note: Some Redmi models (e.g. Redmi Note 8 Pro or Redmi) K30 Pro) after major updates MIUI may reset 4G, This is why the smartphone can't see some of the operator's towers. If the speed drops after the upgrade, manually select the bar in the engineering menu (see section 5).

5. Engineering menu: hidden settings for advanced

If standard methods fail, it's time to turn to the Engineering Mode, where you can manually configure network settings that are usually hidden from the user. Be careful: the wrong changes can lead to loss of communication!

To open the engineering menu, enter the phone code in the application:

##4636##

The Test menu will open. Go to the Device Information (or Network Info) tab and note:

• 📡 Network type: This is the current standard (e.g., the standard, LTE or NR for 5G). If instead of the expected 4G/5G You see. HSPA+ (3G), problem.
• 📶 Signal Level: The value of dBm should be closer to -70 (Good signal. If it's lower -100, You are in a low-coverage area.
• 🔄 Roaming: If roaming is enabled, turn it off in the main settings (Settings) → SIM-map → roaming).

For manually configuring 4G/5G bands:

1. In the engineering menu, select Band Selection (or Set Preferred Network Type).
2. Check all the bands supported by your operator (check them on the provider's website).
3. Save the settings and restart the smartphone.

Hardware solutions: from antenna to firmware

If the software methods are exhausted, but the speed is still low, the problem may be in the hardware.

Verification SIM-cards and slots: Remove SIM-Check the slot, and sometimes the contacts become oxidized or contaminated. Rub them with alcohol and insert them. SIM If you have a Redmi with a hybrid slot (like the Redmi Note 10 Pro), make sure you don't use the second one. SIM or a memory card that may conflict with the main SIM.

Replacement of antenna: In rare cases, the problem lies in a damaged antenna (especially if the smartphone fell).

• 📉 Internet speed drops sharply when the position of the smartphone changes (for example, if you hold it horizontally).
• 📶 The network signal is constantly “jumping” between the two 3G/4G or disappear altogether.
• 🔧 In the engineering menu, the signal level (dBm) is always lower. -110, even in a good-coverage area.

If you suspect a malfunctioning antenna, contact the service center. Self-repair without experience can damage the motherboard.

Custom firmware: On some Redmi models (especially older ones like Redmi 5 or Redmi 6), standard MIUI firmware can artificially limit Internet speed. Alternatively, install custom Android-based firmware, such as:

• 🛠️ LineageOS – pure Android without the limitations of Xiaomi.
• 🚀 Pixel Experience – firmware with features from Google Pixel.
• ⚡ ArrowOS – Optimized for Performance.

Note: custom firmware installation requires unlocking the bootloader and may deprive you of warranty. For detailed instructions, see the XDA Developers forum for your model.

7. Alternative ways to speed up the Internet

If none of the above has worked, consider external solutions:

Use of the VPN: Paradoxically, but sometimes VPN This can increase Internet speed, and it happens if your ISP artificially restricts traffic (trottling). VPN-to a server in your area (e.g. via ProtonVPN or Warp from Cloudflare) and retest the speed.

USB-modem or access point: If your Redmi has a weak signal, but you have another smartphone or USB-A well-received modem, use it as an access point. Connect to its Wi-Fi from your Redmi — this often gives you a more stable connection.

Smartphone cooling: When overheated, the Redmi processor can trott (limit) performance, which also affects Internet speed. If the smartphone is hot, let it cool or use a cooling case.

💡

If all methods have been tried but the speed remains low, the problem is most likely on the operator or provider’s side, contact their support team and provide the speed test results (screenshots from Speedtest).
