Have you noticed that pages in the browser load for eternity, YouTube videos are constantly โbufferedโ, and online games are laid even with a stable Wi-Fi signal, POCO And Mi is more common than it seems, and software constraints may be the reason. MIUI, But the good news is that you can increase the speed 90 percent of the time without changing the fare or buying a new router.
In this article, we will discuss 12 Proven methods โ from basic (reboot router) to advanced (change) DNS, optimization MTU). Special attention will be paid to the โchipsโ Xiaomi, which are rarely mentioned in standard guides: for example, how to turn off background activity of system applications com.miui.analytics or why the โGame Turboโ mode sometimes slows down the network. MIUI 14/15 It is newer, but most of the methods work on older versions.
Before you start, check your current internet speeds through services like Speedtest or FAST.com. Write down the metrics so you can objectively assess the effect of each method. And remember, if the cable speed (on PC) and Wi-Fi speed on Xiaomi differ by 2-3 times, the problem is definitely with the smartphone, not the provider.
1.Diagnostics: why the Internet is slowing down on Xiaomi
Before you set up something, it is important to understand the root of the problem.
- ๐ถ Weak Wi-Fi signal: the smartphone โclingsโ to a far access point with a low signal level, instead of the near one.
- ๐ Channel congestion: the router runs on a congested channel (e.g., 2.4 GHz in an apartment building).
- ๐ฑ Restrictions MIUI: Xiaomiโs default shell restricts background traffic to save battery.
- ๐ Hardware Limits: Cheap models (e.g. Redmi) 9A) have a weak Wi-Fi module that does not pull high speeds.
- ๐ ๏ธ Firmware problems: bugs in MIUI Incorrect network settings after the update.
To narrow down the search, perform simple tests:
- Connect Xiaomi to another Wi-Fi network (like a mobile hotspot on another phone) if the speed is up, your router is a problem.
- Check the speed on another device (laptop, tablet) on the same network, and if it's fast, it's the smartphone.
- Start the plane mode for 30 seconds, then turn it off, and sometimes it resets the grid.
If you've had the same speed after you've done this, move on to the next sections, and if the problem's gone, it's a temporary failure, and you've had enough of a reboot.
2. Wi-Fi Optimization: Selecting Channel, Range and Standard
So, to start with the most common scenario, slow Wi-Fi, and the problem is that the router is not setting the optimal settings for the smartphone, and here's what you can do:
Switch to 5 GHz (if the router supports)
The 2.4 GHz band is heavily congested in cities: dozens of networks can sit on a single channel. The 5 GHz band is less crowded and supports higher speeds (up to 1.3 Gbps vs. 450 Mbps at 2.4 GHz). However, it has a smaller range - if you are far from the router, the signal can disappear.
How to turn 5 GHz on Xiaomi:
- Open the Settings. โ Wi-Fi.
- Click on your network name and select โForget Networkโ.
- Connect again โ two networks should appear in the list: with a suffix _5G (5 GHz and without (2.4 GHz).
- Select the network _5G and enter the password.
๐ก
If there is no 5 GHz network on the list, check your router settings: this range may be disabled. Go to the router control panel (usually at 192.168.1.1) and turn on the option "5 GHz Wireless" or "Dual Band".
2.2. Select a free channel in manual mode
Even in the 5 GHz band, channels can cross to find the freest one.
- Install WiFi Analyzer (or analogue) on Xiaomi.
- Run the scan - the application will show the load of channels.
- Log in to the router settings and manually set the minimum load channel (e.g. 36, 40, 44 or 149, 153, 157 for 5 GHz).
For Xiaomi Mi Router, the way will be as follows: Settings โ Wi-Fi โ Additional settings โ Canal.
2.3. Include the standard 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6)
Older routers often work in mode 802.11n (Wi-Fi 4), which limits speed to 150-450 Mbps. Modern Xiaomi smartphones (starting with the Redmi Note 8 Pro and later) support 802.11ac (up to 1.3 Gbit/s) and 802.11ax (Wi-Fi 6, up to 2.4 Gbps).
To activate the advanced standard:
- Go to the router control panel.
- Find the Wireless Mode or Wi-Fi section.
- In range settings 5 GHz select mode 802.11a/n/ac or 802.11ax (if maintained).
๐ก
If your router is older 5 In this case, the only way to speed up Wi-Fi is to buy a new router that supports Wi-Fi. 5/6.
3. Mobile Internet setting: APN, Network type and priorities
If the mobile Internet is slowed down (4G/5G), The problem may be incorrect settings of the access point (APN), You can't just check the operator's limitations or the wrong type of network:
3.1 Update the settings APN
Incorrect parameters APN โ One of the main reasons for slow mobile Internet is that even if your smartphone automatically tightens your settings, they can be outdated.
How to manually adjust APN Xiaomi:
- Go to Settings. โ SIM-maps and mobile networks โ [yours SIM] โ Access points (APN).
- Click on the three dots in the top right corner and select "New Access Point".
- Enter the parameters for your operator (see table below).
- Save and select a new APN.
| Operator. | APN name | APN | Type of authentication |
|---|---|---|---|
| MTS | mts | internet.mts.ru | PAP |
| Beeline | beeline | internet.beeline.ru | PAP |
| MegaFon | megafon | internet | PAP |
| Tele2. | tele2 | internet.tele2.ru | PAP |
| iota | yota | yota.ru | PAP |
After the change APN Reboot your smartphone โ it will accelerate the application of new settings.
3.2. Forced to turn on. 4G/5G
By default, Xiaomi can automatically switch to the 3G or 2G We're going to have a weak signal, which is a sharp slowdown, to get priority:
- Open the Settings. โ SIM-maps and mobile networks โ [yours SIM] โ Preferred type of network.
- Choose. 4G (preferably 5G/4G/3G/2G (If you have the support of five.
- Turn off the "Switch to" option. 2G to save chargeโ (if any).
What to do if there is no option "5G"?
3.3. check the operator's limitations
Sometimes providers artificially limit speeds due to:
- ๐ Exhaustion of high-speed traffic (for example, after 20 GB, the speed drops to 128 Kbps).
- ๐ Blocking torrents or streaming services.
- ๐ก Overloading of the base station during peak hours.
To check:
- Call the operator and check if the restrictions on your tariff are in effect.
- Try to connect. SIM-If the speed is the same, the problem is not Xiaomi.
- Use it. VPN (For example, Cloudflare WARP) โ If the speed is increased, the operator blocks certain resources.
System settings MIUI: What to turn off for acceleration
MIUI It's known for its "care" for the user, which often results in unnecessary restrictions. Here are the key settings that should be changed:
4.1. disable Adaptive Communication and Traffic Saving
Function "Adaptive Communication" (Settings) โ Battery and productivity โ Adaptive connectivity automatically limits mobile internet speed if the battery is running out fast. Turn it off if speed is more important than autonomy.
Also check:
- Settings โ SIM-maps and mobile networks โ Saving traffic - turn off.
- Settings โ Connections and sharing โ Data Savings โ Turn Off for All Apps.
4.2. Limit background activity of system applications
Xiaomi sins because many system services (com.miui.analytics, com.xiaomi.midrop) are constantly knocking on the network, taking away traffic and speed, to tame them:
- Open Settings โ Applications โ Application Management.
- In the search, enter analytics, find Analytics. MIUIยป and turn off "Autostart" and "Background Activityยป.
- Repeat for Mi Drop, Mi Video, Mi Browser (if not used).
Deactivate "Adaptive communication"|Disable "Traffic savings"|Prohibit background activity of system applications|Update MIUI last-minute|Reset your network settings (if nothing helps)-->
Reset the network settings
If previous methods failed, reset the network settings, which will delete all stored Wi-Fi networks and mobile Internet settings, but often solves connection problems.
Instructions:
- Settings โ About phone โ Resetting โ Resetting Wi-Fi, mobile network and Bluetooth settings.
- Confirm the action and restart the smartphone.
- Connect to Wi-Fi again and set up mobile internet.
๐ก
After you reset the network, check the speed again. If it's grown, the problem was the setting conflict. If it's not, go to the hardware.
Advanced methods: change DNS, MTU firmware
If the basic settings don't work, it's time to dig deeper, and these methods take a little bit more effort, but they can give you 30 to 50 percent speed boost.
5.1.Change. DNS Cloudflare or Google
DNS-The provider's servers often run slowly or block some sites. DNS (Cloudflare or Google can speed up page loading.
How to change DNS to Xiaomi:
- Install 1.1.1.1: Faster Internet (from Cloudflare) or manually configure:
- Go to Settings. โ Wi-Fi โ [your network] โ Change the network โ Additional settings โ Settings IP.
- Select "Static" and enter: DNS 1: 1.1.1.1 DNS 2: 1.0.0.1 (for Cloudflare) or DNS 1: 8.8.8.8 DNS 2: 8.8.4.4 (for Google).
- Save and reconnect to the network.
5.2. Optimize the parameter MTU
MTU (Maximum Transmission Unit: Maximum size of data packet that is transmitted without fragmentation; suboptimal value can cause delays; Xiaomi recommends 1472 (for Wi-Fi) or 1420 (for mobile Internet).
Change. MTU only through ADB (PC required):
- Turn on "Debugging by" USBยป (Settings โ The phone. โ Version. MIUI โ Press 7 times, then return to Settings โ Additionally. โ For developers).
- Connect your smartphone to your PC and execute the command: adb shell settings put global captive_portal_detection_enabled 0 adb shell settings put global captive_portal_mode 0 adb shell settings put global captive_portal_http_url http://connectivitycheck.gstatic.com/generate_204 adb shell settings put global captive_portal_https_url https://www.google.com/generate_204
- For modification MTU (requires root: su ifconfigigig wlan0 mtu 1472 (substitute wlan0 on rmnet_data mobile-internet).
What is ADB and how to install it?
5.3. Update or reflash your smartphone
Firmware bugs are a common cause of network problems. MIUI:
- Settings โ About the phone โ System update.
- If there are no updates but the problem persists, try the manual firmware via the Mi Flash Tool (instructions on XiaomiUI).
Important: If you update before MIUI 14/15 speed has dropped, try to roll back to the previous version or install custom firmware (for example, Pixel Experience).
Hardware solutions: antennas, cooling and module replacement
If the software methods didn't work, the problem could be the hardware.
6.1 Check for overheating
Heating above 60ยฐXiaomi is starting trottling, an artificial performance decline that affects network modules:
- ๐ก๏ธ Install the app AIDA64 and look at the temperature of the processor in the Sensors section.
- ๐ฅ If the temperature is above 50ยฐC in plain, clean the smartphone from dust (especially the charging and dynamics connector).
- โ๏ธ Use a cooling case or fan stand under intense load.
Improve signal reception
A weak signal from Wi-Fi or mobile automatically slows down.
- ๐ก Move the router closer to your smartphone or use a repeater (signal amplifier).
- ๐ถ Mobile Internet: If the home signal is weak 4G, Try an external antenna (e.g. Xiaomi Mi WiFi Amplifier 2).
- ๐ If the smartphone is bad "catchยป 5G, Check your model range support on FrequencyCheck.
6.3. Replace. Wi-Fi/mobile module (extreme case)
If all methods are tried and the speed is low, the network module may malfunction.
- ๐ฅ Falling from a height (especially at the angle where the module is located).
- ๐ Visited in water (even after drying, corrosion can damage contacts).
- โก With severe wear (over 3-4 years old).
The cost of replacing a Wi-Fi module in the service center: from 1,500 โฝ (for Redmi up to 3,000 โฝ (Before repairing, check whether it is cheaper to buy a new smartphone - sometimes it is justified.
๐ก
If you choose to replace the module yourself, buy the original part (the article can be found on the ETradeSupply website). Cheap Chinese counterparts often perform worse or do not support all ranges.
7. Alternative methods: VPN, Proxies and Specialized Applications
Sometimes, the Internet is speeded up by non-obvious methods related to circumventing restrictions or optimizing traffic.
7.1. Use it. VPN throttle-by-pass
Some providers (especially mobile) artificially reduce the speed for certain services (torrents, YouTube, Netflix). VPN Encrypts traffic, making it invisible to the operator.
Recommended VPN for Xiaomi:
- ๐ Cloudflare WARP (Free, minimal speed loss).
- ๐ ProtonVPN (there is a free rate with servers in 3 countries).
- โก 1.1.1.1 (with mode) WARP+) โ blend DNS and VPN.
How to set up:
- Install a VPN from Google Play.
- Select a server in your country (for minimum delays).
- Turn it on. VPN and check the speed.
7.2. optimize traffic with apps
There are utilities that compress traffic and speed up loading due to caching:
- ๐ฑ Opera Max (compresses data for all applications).
- ๐ UC Browser Turbo (accelerates page loading).
- ๐ฎ Game Turbo (built-in to the game) MIUI App for gamers, but can speed up regular traffic).
Note: Traffic compression can reduce the quality of images and videos, but saves megabytes and speeds up loading on weak connections.
7.3 Configure a proxy for specific tasks
Proxy servers are useful if you want to speed up access to certain resources (for example, to foreign sites), for example, to download files from abroad, you can use proxy in Europe or the United States.
How to set up a proxy on Xiaomi:
- Find a free or paid proxy (e.g., HideMy.name).
- Go to Settings. โ Wi-Fi โ [your network] โ Change the network โ Additional settings.
- Select โManual Proxy Setupโ and enter IP port.
๐ก
VPN And proxies can speed up and slow down the Internet, depending on the server. Test the different options and choose the one that gives the best result.
8. Common mistakes that slow down the Internet on Xiaomi
Many users are unwittingly slowing down the Internet speed, and here are the most common mistakes:
- ๐ Use of battery saving mode: it limits background activity and network speed. disable it in Settings โ Battery and productivity.
- ๐ฑ Installing cleaners like Clean Master: They kill network processes, leading to permanent reconnections.
- ๐ Frequent change of Wi-Fi networks: Xiaomi can โforgetโ the optimal settings with frequent reconnection.
- ๐ ๏ธ Disabling Automatic Updates: Outdated software often contains bugs that affect the network.
- ๐ก Using cheap routers without 5 GHz support: they limit speed even for modern smartphones.
Also avoid:
- ๐ซ Open Wi-Fi connections (they often limit speed).
- ๐ซ Simultaneous use of mobile Internet and Wi-Fi (can cause conflicts).
- ๐ซ Installation of custom cores or firmware without compatibility check.
๐ก
If you frequently move between Wi-Fi networks (home, work, cafe), turn on the option โAutoconnect to open networksโ (Settings) โ Wi-Fi โ But be careful, open networks are not secure!
โ ๏ธ Warning: If the speed is still low after all the manipulations, check your smartphone for viruses. Some malware (such as HiddenAds or Joker) steal traffic to display ads or mine cryptocurrency.
