The speed of the internet on Xiaomi smartphones is one of the most common causes of discontent among users, even on flagship models like Xiaomi 14 Ultra or other devices. POCO F6 Pro can have problems with page loading, video buffering, or connection stability, not only with the operatorβs tariff or router, but also with the deviceβs settings.
In this article, we will discuss all the ways to diagnose and optimize speed β from basic checks to hidden functions. MIUI, They don't have the official instructions on them:
- π Measure the actual speed (not the speed the operator shows)
- β‘ Increase Wi-Fi and mobile internet speeds by 2-3 times
- π οΈ Fix typical network configuration errors
- π‘ Choose the best channel and connection standard (2.4 GHz vs 5 GHz vs 6 GHz)
All methods tested on current versions MIUI 14/15 and are suitable for devices from Redmi Note 12 Xiaomi Mix Fold 3. If your model is older 2020 Some menu items may differ β we will warn you about this separately.
1. How to measure the speed of the Internet on Xiaomi
Before you set up something, you need to know how fast you really are. Operators and providers often say "up to 100 Mbps," but the real values can vary by 5-10 times.
Use only these services (the rest often overstate or understate results):
- π Speedtest by Ookla β the benchmark for mobile Internet
- π FAST.com (from Netflix) β better for checking streaming videos
- πΆ nPerf β shows ping and connection stability
It is important to test under the right conditions:
- Connect to the network you check for (Wi-Fi or mobile Internet).
- Close all background applications (especially messengers and cloud services).
- Turn off the VPN if it is turned on.
- Run the test in 3β5 Meters from the router (for Wi-Fi) or in the zone of a confident signal 4G/5G.
If the speed is below the stated by more than 30%, there is a problem, for example, at a tariff of 100 Mbit / s, real 30-50 Mbit / s is normal (distance losses, network load), and 5-10 Mbit / s is a reason for action.
β οΈ Note: Xiaomi with Snapdragon processors 8 Gen 2/3 (for example, Xiaomi 13T Pro) Speedtest may be underrated due to driver limitations. CLI through ADB.
π‘
Before the test, reboot the smartphone β this will reset the network cache and give more accurate results.
2. Wi-Fi Optimization: Choosing a Channel, Standard, and Protocol
Most of the Wi-Fi speed issues on Xiaomi are due to the router settings that are not the phoneβs, and hereβs what to check first:
| Parameter | Recommended value | Why is it important? |
|---|---|---|
| Wi-Fi standard | 802.11ax (Wi-Fi 6/6E) | Increases speed by 30-40% compared to 802.11ac |
| Frequency | 5 GHz (or 6 GHz if supported) | Less interference than 2.4 GHz, but shorter range |
| Channel width | 80 MHz (or 160 MHz if the router supports) | Increases throughput by 2 times |
| Security regime | WPA3-Personal | It is safer and faster than WPA2 |
To change these settings on Xiaomi:
- Open the Settings. β Wi-Fi.
- Click on your network name and select Change Network.
- In the section Additional settings set: π Wi-Fi mode β 802.11 a/b/g/n/ac/ax (if available) πΆ Frequency β 5 GHz (priority) π Security β WPA3-PSK
If your router does not support Wi-Fi 6, but your smartphone has a module (e.g. Redmi). K70 Pro, the speed will still be limited by the router, and then the only thing that helps is to replace the hardware.

3. Acceleration of mobile Internet: settings APN network selection
Speed. 4G/5G Xiaomi is dependent on three key factors:
- Right settings APN (point-of-access).
- Selected type of network (auto, only) 4G, only 5G).
- Signal quality (coverage level and tower load).
Check the APN first:
- Go to Settings. β SIM-maps and mobile networks β [Yours. SIM] β Access points (APN).
- Click on the current profile and compare the settings with the reference ones for your operator (see the table below).
- If there is no profile, create a new one by entering the data manually.
To change the regime:
- Open the Settings. β SIM-maps and mobile networks β [Yours. SIM] β Type of network.
- Choose the right option (we recommend only). 4G stability).
- Reboot the phone.
β οΈ Note: On some Xiaomi models (e.g, POCO X5 Pro) when choosing Only 5G You may lose communications in subways or underground parking lots, in which case you return the car or 4G.
4 Hidden MIUI settings to speed up the internet
MIUI It hides a few features that can improve speed significantly, and they're not on the main menu, but they work on all devices with a high speed. MIUI 12 and newer.
Activation of the "High loading speed" mode:
- Open Settings β Special Opportunities β More
- Activate the switch High download speed.
- This feature disables background traffic optimization, which speeds up file downloads by 15-25%.
2. Disabling "Intelligent Switching" Wi-Fi/mobile":
By default. MIUI It automatically switches to mobile Internet if Wi-Fi is weak, which is useful, but often leads to packet loss and brakes:
Settings β Wi-Fi β Additional β Intelligent switching β Turn off3. reset network settings (if the speed suddenly dropped):
This method helps in 70 percent of cases where the speed has dropped dramatically for no apparent reason, and it resets all network parameters to factory settings, including:
- π± Saved Wi-Fi networks
- π Settings APN
- π‘ Mobile network preferences
How to reset:
Settings β System and device β Additional β Resetting settings β Resetting network settingsβ The "High download speed" mode is enabled"
β Wi-Fi Smart Switching Disabled
β Reset network settings (if there were problems)
β Settings checked APN-->
Programmatic acceleration methods: switching off background processes
Even on top Xiaomi, background apps can eat up to 40% of bandwidth. Here's how to fix it:
1. Restriction of background traffic:
- Go to Settings β Applications β Application Management.
- Select an app (such as YouTube or TikTok).
- Click Mobile Data and Wi-Fi β Background traffic β Limit.
2. Disabling auto-updates:
Google Play and MIUI They update applications in the background, which slows down the speed:
- π± For Google Play: Play Market β Settings β Auto-update of applications β Never.
- π For MIUI: Settings β Annexes β Auto-update β Turn it off.
3.Use of "Productivity Mode":
On smartphones with Snapdragon 8+ Gen 1/2 (for example, Xiaomi 13 Pro) has a hidden mode that prioritizes network tasks:
Settings β Battery β Performance Modes β High PerformanceIn this mode, the processor does not limit the data transfer speed, but the battery goes down faster.
β οΈ Note: On Redmi with MediaTek processors (such as Redmi Note 12), disabling background traffic for system applications (such as Mi Video or Mi Browser) can lead to errors.
π‘
Disabling auto updates and background traffic can increase download speeds by 30-50%, but requires manual monitoring of app updates.
6.The hardware causes of slow Internet and their elimination
If the software methods did not help, the problem may be in the hardware:
- πΆ antenna Wi-Fi/4G β physical damage or oxidation of contacts.
- π Weak signal β the phone canβt hold a stable connection.
- π Problems with SIM-card - wear or improper pruning.
How to check the antenna:
- Call your phone from another device.
- If the communication is interrupted or the sound is lost, the antenna is damaged.
- On Xiaomi with a metal body (such as the Mi 11), antennas are located on the sides - do not close them with your hands.
How to improve the signal:
- πΆ Use a signal repeater (for mobile internet).
- π Move the router closer to the center of the room (for Wi-Fi).
- π οΈ Replace. SIM-New card (especially if you are older than 3 years old).
If you suspect an antenna malfunction, check the error code:
##4636## β Phone Information β Network settingsThe type of network should be LTE or NR (5G). If there is HSDPA or EDGE β phone down 4G/5G, What is the problem with the communication module.
7. Alternative methods: VPN, DNS firmware
If the standard methods donβt work, try the advanced solutions:
Modification of DNS:
DNS-Operator or ISP servers can slow down the loading of sites:
- π Google DNS: 8.8.8.8 and 8.8.4.4
- π‘οΈ Cloudflare DNS: 1.1.1.1. and 1.0.0.1.
- π AdGuard DNS: 94.140.14.14 (blocking advertising)
How to change DNS to Xiaomi:
Settings β Wi-Fi β [Your Network] β Change Network β Additional β IP Settings β Static β DNS 1/22.Use of VPN circumvention:
Some operators artificially limit the speed for certain services (for example, torrents or streaming platforms). VPN helps get around it:
- π ProtonVPN β free, without logs.
- β‘ Windscribe β 10 GB of traffic per month.
Reflashing to custom software:
On some Xiaomi models, for example, POCO F3) stock-fix MIUI speed-strapped LTE up to 150 Mbps, although the module supports 300 Mbps+ Mbit/s. Installing custom firmware (e.g. Pixel Experience) removes this limitation.
β οΈ This is a risky method β it requires unlocking the bootloader and can deprive you of warranty.
