Internet speed on Xiaomi, Redmi and smartphones POCO It's often a headache for users -- even with a stable signal, pages load slowly, video slows down, and online games get laid. MIUI, In this article, we will discuss 12 proven ways to speed up mobile and Wi-Fi Internet, including hidden firmware features, optimization and optimization. DNS, configuration of the communication module and even hardware solutions for older models.
It's important to understand that not all methods are equally effective, for example, resetting network settings will help with software failures, but it will not save the operator from an overloaded tower. We tested every method on devices from Redmi Note 10 Pro to Xiaomi 13 Ultra – in the article only those solutions that gave measurable speed gain (from the top of the list). +15% +200% depending on the initial conditions. Let's start with the simplest steps and get to the advanced tricks for power users.
1.Diagnostics of the current speed: without it, any settings are meaningless
Before optimizing, you need to understand exactly where your Internet is slowing down. On Xiaomi smartphones, the problem can lie in:
- 📶 Weak signal (mobile network or Wi-Fi)
- 🖥️ Overloaded. DNS (Especially relevant for operators of Beeline / Tele2)
- 📱 Restrictions MIUI (background activity, energy saving)
- 🔧 Hardware limits (old modem, for example, in Redmi) 4X)
For accurate diagnosis:
- Install Speedtest by Ookla or FAST.com (from Netflix).
- Run a speed test. 3 Time in a row in different conditions: Next to the Wi-Fi router In another room On the mobile network (4G/5G)
global
Critical indicators that should be noted:
- Ping above 100ms – lags in games and delays in loading pages.
- Download speed below 10 Mbps per 4G 50 Mbps on Wi-Fi – a sign of a problem.
- Speed fluctuations ±30% between tests - unstable connection.
⚠️ Warning: If other devices (laptop, tablet) are running at normal speeds and Xiaomi isn't, the problem is the phone.
2. Optimizing the mobile Internet (4G/5G): From network selection to hidden settings
Mobile Internet on Xiaomi is often slowed down due to incorrect network mode or firmware restrictions.
2.1. Forced network selection 4G/5G (instead of "Auto")
By default, Xiaomi smartphones use Auto mode, which can connect to congested networks 3G weak 5G. Forced choice often gives you speed gain:
- Go to Settings. → SIM-maps and mobile networks → [Yours. SIM] → Type of network.
- Select Only. LTE (for 4G) or 5G (vehicle (if supported).
- Reboot the phone.
Important: On some models (Redmi) 9A, POCO M3) Option Only LTE In this case, the engineering menu will help (see section 5).
Disable VoLTE and VoWiFi (if not used)
VoLTE technologies (voice on) LTE) And VoWiFi can conflict with data, especially on older firmware:
- 📞 Settings → SIM-map → [Yours. SIM] → Challenges by LTE (disconnect)
- 📶 Settings → Wi-Fi → Additionally. → Wi-Fi Calls (Disable)
💡
If after the VoLTE shutdown, the mobile Internet disappears, return the settings back - your operator can link data to this function (relevant to Tele2).
2.3 Resetting mobile network settings
Sometimes the connection settings get contaminated after an update or operator change, and resetting helps in 60% of cases:
- Go to Settings. → SIM-maps and mobile networks → [Yours. SIM] → Settings of access points (APN).
- Click on three dots in the upper right corner → Reset to factory.
- Restart your phone and wait for the automatic setup. APN (It can take up to 5 minutes).
| Problem. | Reason. | Decision |
|---|---|---|
| The Internet is there, but the pages are not loaded | Wrong. APN or DNS | Reset APN + shift DNS (section) |
| Speed jumps (50 Mbit, then 1 Mbit) | Switching between 4G/3G | Compulsory regime Only LTE |
| High ping in games | Overloaded operator tower | Change of location or operator |
3. Wi-Fi acceleration: from channel selection to hidden features MIUI
Wi-Fi on Xiaomi is often slowed down due to two reasons: an overloaded router channel or power saving limitations. MIUI. Let's look at both cases.
3.1 Optimization of the channel and the Wi-Fi standard
If your router is running on a loaded channel (for example, a channel 6 in the 2.4 GHz range), the speed may drop by 2-3 times.
- Install the WiFi Analyzer app.
- See which channels are least loaded (in the 2.4 GHz range, choose 1, 11 or 13; in 5 GHz, any with minimal load).
- Go to the router settings (usually 192.168.0.1 or 192.168.1.1) and change the channel manually.
For maximum speed:
- 📶 Use the 5GHz band (if the router supports it).
- 🔄 Turn on the mode. 802.11ac (or Wi-Fi 5) in the router settings.
- 🚫 Turn it off. WMM (Wi-Fi Multimedia, if there are lags in games.
Disable "Intelligent switching" in MIUI
The function of intelligent switching to MIUI It automatically switches the phone between Wi-Fi and the mobile Internet if the signal is weak, but often it goes too aggressively, breaking the connection:
- Go to Settings → Wi-Fi → More
- Disable options: Autoconnect to open networks Intelligent switch Notify of open networks
Reboot the phone.
Free channel selected (via WiFi Analyzer)|The router is running 802.11ac (5 GHz)|"Intelligent switching" is disabled in MIUI|The width of the router channel is set at 40 MHz (for 5 GHz)-->
Shift DNS speed up page loading
Xiaomi is using the default DNS your carrier or provider, which is often overloaded. DNS (Google or Cloudflare can speed up site openings by 20 to 50%.
How to change DNS to Xiaomi:
- Go to Settings. → Wi-Fi.
- Click on your network. → Change the network → Additional settings → Settings IP.
- Select Static and enter: DNS 1: 1.1.1.1 (Cloudflare) DNS 2: 8.8.8.8 (Google)
Save and reconnect to the network.
Important: For mobile internet (4G/5G) DNS It changes with apps like 1.1.1.1: Faster Internet – Standard Means MIUI You can't do that.
4. Disconnect background activity and energy saving
Firmware MIUI aggressively restricts the background activity of applications to save battery life, which often leads to downloads, slow messengers and brakes in online games.
Setup of auto-start and background activity
By default. MIUI It blocks auto-runs most applications:
- Go to Settings → Applications → Application Management → Autorun.
- Enable auto-run for critical applications (e.g. Telegram, YouTube, SberBank Online).
- Go back and select Permissions → Background Activity.
- Set the right applications mode without restrictions.
How to check if the limit is MIUI appendix?
4.3 Clearing the cache and data of the Google Play Services
Sometimes slow internet is associated with crashes in Google Play Services, which are responsible for syncing and push notifications.
- Go to Settings → Applications → Application Management → All applications.
- Find Google Play Services → Warehouse.
- Click Clear the cache and Clear the data.
- Reboot the phone.
⚠️ Note: After the data is cleared, Google Play Services may temporarily disappear push notifications (for example, in Viber or WhatsApp.
5. Advanced settings: engineering menu and ADB-team
If the standard methods didn't work, it's time to dig deeper. This section contains hidden settings that don't show you. MIUI, But they can speed up the internet significantly.
5.1. Engineering menu for optimizing mobile network
You can manually select the type of network through the engineering menu, disable unnecessary bandwidth, and even increase the power of the module. Careful: incorrect settings can lead to loss of communication!

These commands are off:
- 🔍 Checking the captive portal (accelerates the connection to Wi-Fi).
- 📊 Restrictions on background traffic.
- 🔄 Automatic switching between networks.
5.3. Change of parameters TCP/IP ping-lower
For gamers and streamers, not only is the channel critical, but the quality of the connection is critical. TCP/IP:
- Install the app TCP Optimizer.
- Choose a High Speed or Gaming profile.
- Apply the settings and restart the phone.
For experienced users: Manually set the following parameters (via ADB termux):
sysctl -w net.ipv4.tcp_window_scaling=1
sysctl -w net.ipv4.tcp_timestamps=1
sysctl -w net.ipv4.tcp_sack=1
sysctl -w net.ipv4.tcp_no_metrics_save=16 Hardware solutions: if software methods do not help
If you've tried all the settings, but the Internet is still slow, the problem may be the hardware of your Xiaomi, and let's figure out what to do in this case.
Checking the communication module for physical damage
A weak signal or connection breaks may be caused by:
