How to increase the speed of the Internet on the phone Xiaomi Redmi: the complete guide

Why Xiaomi Redmi is slowing down the Internet and how to fix it

Slow page loading, constant video buffering or sudden communication breaks are familiar to Xiaomi Redmi owners? Internet speed problems on smartphones of this line are often not due to hardware limitations, but to incorrect settings, overloaded networks or software conflicts. Even flagship models like the Redmi Note 12 Pro+ or the budget Redmi 10A can suffer from low speed due to standard MIUI parameters, which are optimized for the average user by default, rather than for maximum performance.

In this article, we’ll look at 12 proven ways to speed up mobile internet (4G/5G) and Wi-Fi on Xiaomi Redmi, including hidden MIUI settings, hardware tricks and tariff recommendations. All methods tested on 2020-2026 models and do not require root rights. And if you’ve already tried “standard” tips like rebooting a router, you’ll find solutions deeper than typical instructions.

Before you start settings, check the baseline speed through services like Speedtest or FAST.com. Write down the results: this will help assess the effectiveness of each method, for example, if ping is above 100 ms and download speeds are below 10 Mbit / s at a tariff of 50+ Mbit / s, there is definitely a problem.

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

By default, Xiaomi Redmi uses an automatic network selection mode, which does not always choose the fastest communication standard. Manual control of parameters can give speeds up to 30-50%, especially in unstable coverage.

Open the Settings. → SIM-maps and mobile networks → [yours SIM] → Network type and install:

• 📶 For 4G: Select Only. LTE (switch off 3G/2G, slow-motion).
• 🚀 For 5G: activate 5G/4G/3G/2G (Auto), but disable the option "Saving traffic" in the same menu - it artificially limits the speed.
• 🔄 For unstable signal: Enable "Enhanced" LTE" (If you have it in your model, it is a forced mode with speed over stability priority.

Also check the settings. → SIM-map → Access points (APN). Many operators (MTS, Beeline, Tele2) have standard settings. APN For example, MTS in 2026 is relevant:

Name: MTS


APN: internet.mts.ru




Proxy: not installed




Port: not installed




User name: mts




Password: mts

⚠️ Attention: If after the shift APN Internet is gone, return the standard settings! Some operators (e.g. Yota) block manual change APN.

2. set up Wi-Fi for maximum speed

Wi-Fi on Xiaomi Redmi is often slower due to automatic channel selection or outdated security protocols. The first thing to do is force the 5 GHz band (if your router supports it).

1. Go to Settings → Wi-Fi → [your network] → Change the network.
2. Turn on "Additional settings."
3. Select “Only 5 GHz” (if available) or “5 GHz preferred”.
4. Set channel width: 80 MHz (for routers with AC/AX support).

If your model doesn’t have manual range settings (like Redmi 9A), use the WiFi Analyzer app to analyze channel loads. Switch to the least loaded channel in the router settings (usually 36, 40, 44 or 149–165).

⚠️ Note: On older routers (until 2018), turning on 80 MHz can lead to communication interruptions. In this case, install 40 MHz or update the router's firmware.

3. Disconnect background traffic and optimise MIUI

MIUI aggressively caches data and stores background processes that can eat up to 30 percent of the Internet speed.

• 🔄 Go to Settings. → Annexes → Application management → Triple point (⋮) → Reset application settings. This will clear the cache of all programs without deleting data.
• 🚫 Turn off autoloading of unnecessary apps: Settings → Battery and productivity → Auto-run control. Leave only messengers and key services.
• 📉 Enable Traffic Saving (but not to be confused with Battery Saving!): Settings → Connections and sharing → Traffic savings: This will limit background activity, but it won't affect download speeds.

Pay special attention to Google Play Services and MIUI Daemon, which system processes often consume traffic in the background. To check their activity, use NetMonitor (showing traffic for each process in real time).

Critical setting for Redmi on MIUI 13/14: disable "MIUI Optimization" in developer mode (Settings → About Phone → MIUI Version → 7 taps, then Settings → Additional → Developers → MIUI Optimization).This will remove the artificial speed limits that Xiaomi has introduced to "extend battery life."

💡

If after disabling MIUI Optimization, the phone began to warm up - return the setting back and instead limit background activity through "Battery and Performance → Background Limitation".

Hardware Methods: How to Physically Enhance Signal

If the software settings didn't work, the problem could be physical limitations, like a weak operator signal or interference.

For mobile Internet:

• 📡 Use a signal repeater. 4G/5G (Xiaomi Mi Wi-Fi Repeater 2) It's a base station signal booster, and it can increase the speed of the base station. 50–100%.
• 🔋 If the phone is under 20%, switch to plane mode for 10 seconds, then back again.
• 🛠️ For models with removable back cover (Redmi 9, 8A Check the integrity of the antenna contacts. Oxidation or contamination can reduce the signal by 30-40%.

For Wi-Fi:

• 📶 Move the router closer to your phone or use the Mesh system (e.g. Xiaomi Mi Mesh Router) AX3000) large-room.
• 🔌 Connect your phone to the router via USB-cable (if the router supports USB tethering) this will give a stable 900+ Mbps, even on budget models.
• 🔄 If the speed drops when connected to 5GHz, try 2.4GHz with a 1, 6, or 11 channel – they are less prone to interference.

⚠️ Note: Do not use "signal amplifiers" on AliExpress without certification! They can violate the laws of the Russian Federation (Article 13.3 of the Administrative Code) and cause interference to neighbors).

5. Alternative DNS and VPNs to bypass restrictions

Sometimes the slow speed is not due to the phone, but to the locking of the operator or provider, for example, MegaFon and Beeline can artificially limit the speed for some services (Torrent, Netflix), decides whether to change the DNS or use a VPN.

How to change DNS to Redmi:

1. Go to Settings → Connections and Sharing → Private DNS.
2. Select "Host Name of Private DNS Provider".
3. Enter one of the addresses: dns.google (Google) 1dot1dot1dot1.cloudflare-dns.com (Cloudflare) dns.quad9.net (Quad9, blocks malicious sites)

VPNs to bypass restrictions: Free services like ProtonVPN or Warp (from Cloudflare) can increase speed by 10-50% if the operator slows down traffic. However, some VPNs, on the contrary, slow down speed – test different servers.

• 🌍 Connect to servers in your country (lesser ping).
• 🚫 Avoid. VPN speed limit (for example, TunnelBear only gives 500 MB/months).
• ⚡ Use WireGuard (built into Warp or NordVPN) – it’s faster than OpenVPN.

💡

Changing DNS only helps with name resolution issues (such as slow loading sites), and if speed is slow in Speedtest, DNS is not to blame.

6. Resetting network settings and flashing

If nothing works, the problem may be system conflicts or damaged configurations, in which case resetting network settings or flashing will help.

Reset network settings (without data loss):

1. Go to Settings → About Phone → Settings Reset → Reset your Wi-Fi, mobile network and Bluetooth settings.
2. Confirm action. The phone will reboot, and all network settings will return to factory settings.
3. After resetting manually set up APN (see Section 1) and Wi-Fi (see Section 2).

Flashing (if the reset didn't help): An outdated version of MIUI may contain speed-impairing bugs.

• 🔄 Through OTA: Settings → Updating the system.
• 📥 Manual: download the latest version from the official Xiaomi website and install through Settings → Updating the system → Triple point (⋮) → Select a firmware file.

⚠️ Warning: Don’t install custom firmware (like LineageOS) to increase internet speed! they often break the communication module on Redmi, especially in models with MediaTek (Helio G-series).

7.Verification for viruses and malware

Viruses and adware can steal traffic in the background, slowing down speeds. For example, the Android.Triada Trojan (distributed via pirated APKs) can consume up to 1 GB/day.

Install Malwarebytes or Avast and perform a full scan. Delete any threats you find, then:

1. Clear the cache in Settings → Storage → Clear the cache.
2. Check the list of installed apps for suspicious ones (for example, with names like “Super Cleaner” or “Battery Saver Pro”).
3. Disable Administrator Rights for Unknown Applications: Settings → Passwords and Security → Device Administrators.

If there are no viruses, but traffic still “leaks”, check the system applications:

• com.miui.analytics – sends data to Xiaomi (can be disabled via ADB).
• com.android.vending – Google Play Store (limit background activity).
