How to speed up the Internet on Xiaomi: proven methods for Redmi, POCO mi

Slow internet on Xiaomi smartphone is a problem faced by even owners of the flagship models Mi 13 Ultra or Redmi Note 12 Pro+. Lags when watching videos, eternal “spinning circles” in the browser or sudden connection breaks sometimes drive crazy, the reasons can lie in the settings of the device itself, and external factors – from an overloaded router to the limitations of the mobile operator.

In this article, we’ll break down 12 proven ways to speed up the internet on Xiaomi, starting with basic settings. MIUI And then you end up with the hidden functions of the engineering menu:

• 🔍 Diagnose the real speed of the connection (not what the operator shows)
• ⚡ Optimize Wi-Fi and mobile network settings for maximum performance
• 🛠️ Fix common bugs MIUI, internet-stop
• 📡 Extract maximum from weak signal 4G/5G long-distance Wi-Fi

Important: Not all methods are equally effective for different models. POCO F5 Snapdragon 7+ Gen 2 will help overclock mobile Internet through the engineering menu, and for Redmi 10A With a budget chipset, it's better to focus on optimizing the background processes.

1. Real speed check: why tests lie

Before you set up anything, you need to know where your Internet is going to slow down. Most users are limited to running a Speedtest or a Yandex Internet meter, but these applications often show inflated values due to the operator's caching of data, to get honest numbers:

1. Disable all background apps through Settings → Annexes → Launched.
2. Connect to a server located in your region (in Speedtest, select manually).
3. Do the test 3-5 times in a row and take the average value.

If the speed is less than 30% below the stated operator, the problem may be:

• 📶 Overloaded tower (especially relevant for the 5G densely populated)
• 🔄 Throttling traffic (the operator artificially reduces the speed after the limit is exhausted)
• 📱 Hardware limitations (cheap Redmi models often have weak Wi-Fi modules)

For accurate diagnosis, use NetMonster, which will show:

• Real bandwidth (RRC State)
• Type of connection (LTE CA, 5G NSA/SA)
• Signal level in dBm (optimum: higher) -90 dB)

⚠️ Note: If NetMonster is displayed LTE: RRC Idle, your smartphone is constantly losing connection to the tower. This is a typical problem Xiaomi on firmware. MIUI 13–14 – Network settings need to be reset.

2. Optimization of Wi-Fi settings: hidden parameters MIUI

By default. MIUI It hides a number of important Wi-Fi options that can speed up the connection significantly:

1. Go to Settings. → Wi-Fi.
2. Tap on your network name and select Change Network.
3. Activate Advanced Settings (if you don’t have an option, read more about the Engineering Menu).

In the menu that opens, pay attention to:

• 🔗 Wi-Fi mode: Choose 802.11ac (5 GHz instead 802.11n (2.4 GHz if your router supports.
• 📶 Frequency band: for Xiaomi 12/13 Series available mode 160 MHz (increases speed to the speed of the 2 Gbps).
• 🔄 Auto Connection: Disconnect if the network is unstable — MIUI may cling to a weak signal.

For models with Qualcomm Snapdragon (for example, POCO X5 Pro) Wi-Fi Assist is available, which automatically switches to mobile Internet when the signal is weak:

→ SIM-maps and mobile networks → Wi-Fi Assist settings

💡

If Wi-Fi is getting worse after the changes, reset your network settings via Settings → System system → Resetting settings → Resetting Wi-Fi, Mobile Internet and Bluetooth settings.

3. Overclocking the mobile Internet (4G/5G) through the engineering menu

Engineering menu (##4636##) Allows you to manually configure mobile network settings that are limited by default MIUI. This method is especially effective for smartphones with Qualcomm chipsets (Snapdragon). 7xx/8xx) MediaTek Dimensity.

Instructions:

1. Enter the dialer ##4636##.
2. Select Phone Information.
3. Scroll down to the Set preferred network type block.

For maximum speed, select:

• 📶 LTE/5G (Auto - for modern models (Xiaomi) 13T, POCO F5)
• 🔄 LTE only if 5G Unstable (Relevant to Redmi Note 11 Pro)+)
• ⚡ NR/LTE/TD-SCDMA/GSM — forced-mode 5G (Snapdragon only 8 Gen 1/2)

For MediaTek chipsets (e.g., Redmi Note 12 with Helio) G99) Additional settings are available in the menu ##36446337##:

• 🔧 Band Lock: specific frequency binding (e.g. Band 3 for better coverage)
• 📊 CA Configuration: Incorporation of carrier aggregation (LTE CA) speed up

⚠️ Attention: Incorrect settings in the engineering menu can lead to loss of the network. If after changes the Internet is lost, reset through Settings → SIM-map → Resetting mobile network settings.

4. Disabling background processes and optimizing MIUI

MIUI It is known for its “gluttony” to background processes that can eat up to 30% of bandwidth, especially on budget models (Redmi). 10C, POCO M5), where a weak processor can't multitask.

To free up the channel for the Internet:

1. Turn off auto-update apps in Google Play → Settings → Auto-update apps.
2. Ban background activity for unnecessary apps: Settings → Annexes → Application management → [Select an application] → Battery → Limit background activity
3. Turn off Mi Cloud Sync and Autoboot MMS In Settings → Accounts. Google/Xiaomi.

For advanced users:

• 🛠️ Install. ADB and execute commands to disable Mi-services: adb shell pm disable-user --user 0 com.miui.analytics adb shell pm disable-user --user 0 com.xiaomi.midrop
• 🔧 Use Greenify to Force Background Process Hibernation.

In the models with MIUI 14, a new feature called Smart Optimization comes in, which defines priority applications by itself:

Settings → Features → Smart Optimization → Set priorities

5.Amendment DNS: Why it works and which ones to choose

Xiaomi is using the default DNS your carrier, which is often overloaded or blocking some traffic. DNS It can speed up page loading by 20-50:

To change the DNS to Xiaomi:

1. Go to Settings. → Wi-Fi.
2. Tap your network. → Change the network → Additionally. → Settings IP.
3. Select Static and enter the selected DNS.

For the mobile Internet (3G/4G/5G) need to DNS Changer or manual prescribing through APN:

→ SIM-maps and mobile networks → [Your SIM] → Access Points (APN) → [Select APN] → DNS-servers]

⚠️ Note: Some operators (for example, MTS or Beeline) block the change DNS It's a network level, and it's only going to help. VPN DNS-over-HTTPS (e.g. 1.1.1.1 from Cloudflare).

6. Hardware restrictions: what to do if iron brakes

If all software methods have been tried and the internet is still slow, the problem may be in the hardware of the smartphone.

• 📡 Weak Wi-Fi module: budget models (Redmi) 9A, POCO C40) They are equipped with single-band 2.4 GHz chips that do not support 802.11ac.
• 📶 Outdated modem: for example, Redmi Note 8 Pro with Helio G90T supportive 5G and has a weak antenna.
• 🔋 Overheating of the processor: when loading Snapdragon 720G (Redmi Note 10 Pro: Tlottlites and slows down internet speeds.

Decisions:

• 🔧 For weak Wi-Fi: Use a signal repeater or connect via USB Ethernet adapter (works on Xiaomi) 11/12/13 series).
• 📶 For poor mobile signal: install an antenna amplifier (e.g. Xiaomi Mi WiFi Amplifier 2).
• ❄️ For overheating: Turn off High Performance Mode in Settings → Battery → Performance mode.

For models with MediaTek (for example, Redmi Note 12) modem optimization is available through the application MTK Engineering Mode:

Band Selection → LTE Band → Select priority bands (for example, Band 3, 7, 20 for Russia)

💡

If your smartphone is older than 2020 and does not support 5G, Don’t waste time setting up 5G-Better focus on optimizing networks. 4G (LTE) Or switch to Wi-Fi.

7. Network Settings Reset: When It Really Helps

If the Internet on Xiaomi is slow after the update MIUI If you change firmware, it could be a configuration conflict, and then you can reset the network completely:

Settings → System → Resetting → Resetting settings Wi-Fi, mobile Internet and Bluetooth

What's being dropped:

• 🔄 All saved Wi-Fi networks and passwords
• 📱 Settings APN (mobile Internet access points)
• 🔗 Settings of Bluetooth devices
• 📡 Settings VPN proxy

After discharge:

1. Reboot your smartphone.
2. Manually set up APN for your operator (options can be found on the provider’s website).
3. Connect to Wi-Fi and check the speed.

⚠️ Note: On some models (Xiaomi 12 Lite, POCO X4 Pro) after reset, the VoLTE option disappears. To return it, go to Settings → SIM-map → [Yours. SIM] → Enable VoLTE.
