Slow internet on Xiaomi devices is a problem faced by both owners of budget Redmi and flagship Mi 13 Ultra or Xiaomi devices. POCO F5. The reasons may lie in the wrong settings of the smartphone, overloaded Wi-Fi network, outdated router software or even restrictions on the part of the mobile operator. But in 90% of cases, you can increase the speed without buying new equipment β just know what parameters to adjust.
In this article, we will discuss practical methods of speeding up the Internet at the smartphone level (including hidden settings). MIUI), And at the router level, as in Xiaomi Mi Router, Redmi Router and AiOT Router, we'll focus on problem diagnosis, and you'll learn to distinguish hardware from software constraints so you don't waste time on useless manipulation. MIUI 14/15 and router firmware 2023β2026 year-end.
Before you start setting up, check your current Internet speed with apps like Speedtest by Ookla or Fast.com (from Netflix). Write down the results, which you'll need to evaluate the effectiveness of the changes. If the speed on Wi-Fi and mobile networks differs by many times, the problem is more likely the router or its location. If both networks slow down, the settings of the smartphone or the operator's tariff are to blame.
Please note: some methods (e.g., change of DNS shutdown IPv6) You may be in conflict with your ISP's policies, and you make all the changes at your own risk, but if you follow the instructions, the risks are minimal.
1. Optimizing the mobile Internet (4G/5G) Xiaomi
If the internet is slowing down on the mobile network, not via Wi-Fi, start by checking the fare. Go to your carrierβs application (for example, MTS Connect, My Beeline or Tele2) and make sure that:
- πΆ The tariff plan is not exhausted (especially if you have a βno-limitβ with a restriction after a certain traffic).
- π± Network mode corresponds to the capabilities of the smartphone (for example, POCO X5 Pro 5G should be operating 5G/4G/3G, not 4G).
- π Roaming is disabled if you are not abroad (sometimes the smartphone accidentally goes to roaming the home network).
Next, go to the smartphone settings:
- Open the Settings. β SIM-maps and mobile networks.
- Choose yours. SIM-map β Type of network.
- Set up a preferred network type: 5G/4G/3G/2G (For stability, you can choose only 4G, if 5G in your region is unstable.
Hidden setting MIUI: Enable the Improved Mode LTE (Enhanced 4G), It reduces the delays in data transmission:
- Enter the dialer code: ##4636##
- Go to Phone Information β Select Set your preferred network type.
- Choose. LTE/UMTS auto (PRL) or NR/LTE/UMTS auto (for 5G-device).
π‘
If the Internet is gone after the network change, reboot your smartphone. Sometimes the mobile phone module takes time to reconnect.
If the speed is still low, try resetting the settings. APN:
- Go to Settings. β SIM-maps and mobile networks β Access point (APN).
- Click on three dots in the upper right corner β Reset to default values.
2. Wi-Fi acceleration on Xiaomi: from channel selection to router firmware
Wi-Fi is the most capricious connection, because its speed is affected by the settings of the smartphone, the router, and even neighboring networks.
- π‘ Check whether your Wi-Fi is running at 2.4GHz (range longer but speed lower) or 5GHz (faster but worse through walls).
- π Go to your router settings (usually at 192.168.31.1 or miwifi.com) and see how many devices are connectedβsomeone may be stealing your traffic.
- π Use the WiFi Analyzer app (available on Google Play) to see the congestion of channels. If your channel has many neighbors, that's why you're stuck.
Optimal settings of the Xiaomi router:
| Parameter | Recommended value | Explanation |
|---|---|---|
| Wi-Fi mode | 802.11ac (5 GHz) / 802.11n (for 2.4 GHz) | Newer standards (ax) are not supported by all devices. |
| Channel width | 40 MHz (5 GHz) / 20 MHz (2.4 GHz) | Greater width = higher speed, but more interference. |
| Canal | Auto (or manually select the least loaded) | Use WiFi Analyzer for analysis. |
| Security | WPA2-PSK or WPA3-PSK | Avoid the outdated. WEP β It's not only unsafe, it's also inhibiting the connection. |
If you have a Xiaomi router with MiWiFi firmware, upgrade to the latest version:
- Go to the routerβs web interface (miwifi.com).
- Go to General settings β Update firmware.
- If the update is not available, download the firmware from the official Xiaomi website and download it manually.
How to reset the Xiaomi router to factory settings?
A critical mistake of many users: the use of DNS-The default provider (usually DNS Your ISP, which is often slowing down. Replace it with faster alternatives:
- On your smartphone: Settings β Wi-Fi β Additional β IP settings β Static.
- In the field DNS 1 specify 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google).
- In the field DNS 2 specify 1.0.0.1 or 8.8.4.4.
3. Hidden settings MIUI speed up the Internet
MIUI It has a few "secret" features that can dramatically improve Internet speed, but they're hidden in the developers or the engineering menu!
Disabling background traffic restriction:
By default. MIUI restricts Internet consumption to background applications to remove the restriction:
- Go to Settings β Applications β Application Management.
- Select an app (such as YouTube or Telegram) β Data limitation.
- Turn off the option to limit background traffic.
Enabling Developer Mode and Optimizing the Network Buffer:
- Activate Developer Mode: Settings β About Phone β MIUI version (click 7 times).
- Back to Settings β Additionally. β For developers.
- Find the parameters: π Limit background processes β Set the standard limit. πΆ Turn off the absolute speed limit (if any). π§ Turn on 4x MSAA (Improves graphics performance, indirectly affects content loading speed).
Network reset: If nothing helps, perform a complete network reset, which will delete all stored Wi-Fi and passwords, but often solves connection problems:
- Settings β About the phone β Reset settings β Reset network settings.
- Confirm the action and restart the smartphone.
Make a backup copy of Wi-Fi passwords
Write down the settings. APN mobile operator
Make sure that the smartphone has enough charge (at least 50%)
Disable important background tasks (such as downloading files)-->
4. Hardware methods: antennas, cooling and router location
If the software settings didn't work, the problem might be physical limitations.
- π‘ The router is standing in the corner of the room or behind furniture β the signal is weakened.
- π₯ Overheating of the router (especially relevant for Xiaomi Mi Router) 4A Redmi Router AC2100) This leads to automatic power reduction.
- π± A smartphone has a damaged Wi-Fi or mobile network antenna (often after falls).
The optimal location of the router:
- π Place the router in the center of the apartment, at an altitude of 1-1.5 meters from the floor.
- π« Avoid neighborhoods with microwaves, cordless phones, and other sources of interference.
- π If you have a dual-band router, divide the 2.4 GHz and 5 GHz networks into different ones. SSID (names) so that devices are automatically connected to the optimal frequency.
Checking the antenna of the smartphone:
If the mobile internet speed has dropped after a physical injury (hit, fall), the antenna contact may have gone off.
- Call your smartphone from another phone and walk around the room with it.
- If in some places the connection disappears completely (even where it was before), and on other devices the signal is stable, the problem is in the antenna.
- In the service center Xiaomi antenna diagnostics is ~500β1000 rubles.
π‘
If the router overheats, set it vertically (for better ventilation) or use a cooling stand.Overheating above 70Β°C can reduce speed by 30 to 50%!
5. Alternative methods: VPN, Proxies and traffic optimization
Sometimes the Internet is slowed down not because of hardware problems, but because of the limitations of the provider.
- π VPN β It masks your traffic by bypassing some types of locks.We recommend Cloudflareβs ProtonVPN or Warp (free).
- π Shift. DNS β If the provider blocks certain sites, try it. DNS AdGuard (94.140.14.14), which also filters ads.
- π¦ Traffic Optimizers β apps like Internet Speed Master or NetOptimizer (available on Google Play) automatically select the best settings for your network.
How to set up a VPN on Xiaomi:
- Download the app VPN (For example, ProtonVPN from Google Play.
- Register and select a server in your country (for maximum speed).
- Turn it on. VPN and check the speed - sometimes it grows 2-3 times due to bypassing the "throttling" of the provider.
Warning of VPN:
β οΈ Note: some banking applications (SberBank, Tinkoff) and services (Public Services) block access when turned on VPN. Disable it before using such services.
Proxy servers are a less reliable, but sometimes effective way to set up proxy servers on Xiaomi:
- Go to Settings. β Wi-Fi β Additionally. β proxy server.
- Select Manual and enter the proxy address (e.g. proxy.example.com) and port (8080).
- Save your settings and reconnect to the network.
6.Diagnostics of problems: how to understand who is to blame β smartphone, router or provider
Before you can set up something, you need to pinpoint the source of the problem. Here's a simple diagnostic algorithm:
Step 1. Check the speed on different devices:
- π± If the smartphone Xiaomi Internet is slow, and on a laptop or other phone β normal β smartphone-challenge.
- π» If on all devices through Wi-Fi slowly, and on cable (if it is possible to connect a laptop via Ethernet) β normal β router.
- π‘ If both cable and Wi-Fi are slow β provider.
Step 2. Check ping and stability:
Open Command Prompt (on PC) or PingTools app (on Android) and execute the command:
ping -n 50 8.8.8.8If packet loss (>5%) or high ping (>100 ms is a problem as a connection, not as a speed per se:
- Interference on the line (for mobile Internet).
- The router's overloaded channel.
- Faulty cable (if a wired connection is used).
Step 3: Check the load on the network:
If the speed drops at a certain time (e.g. in the evening), your channel may be overloaded by other users.
- π Apartment buildings with a common Internet (for example, from Rostelecom on technology) PON).
- πΆ Mobile Internet during rush hour (18:00β23:00).
π‘
If you have a Xiaomi Mi Router, go to its settings (miwifi.com) and look at the load graph in the Network Status section. If the load peaks coincide with the speed drop, the problem is congestion.
7.Firmware and kernel updates: when it really helps
Outdated software is one of the main reasons for slow Internet, but updates need to be installed correctly.
Update MIUI smartphone:
- Go to Settings β About the phone β System update.
- If you have an update, install it. Pay attention to the file size: if it's larger than 1 GB, connect to Wi-Fi.
- After the update, reset the cache: Settings β Memory. β Clear the cache.
Update of the firmware of the Xiaomi router:
For Xiaomi routers (Mi Router, Redmi Router, AiOT Router series), the current firmware can increase speed by 20-30%.
- Go to the routerβs web interface (miwifi.com or 192.168.31.1).
- Go to General settings β Update firmware.
- If automatic updates are not available, download the firmware from the official Xiaomi website (support section) and download it manually.
Reflashing to custom software:
For power users: some Xiaomi routers (e.g. Mi Router) 3G or R3P) They support alternative firmware like OpenWRT or Padavan, which can give you speed gains from an optimized core, but:
β οΈ Warning: Unofficial firmware can take away your warranty and may contain vulnerabilities, and install them only if you are confident in the sources and are prepared for possible compatibility issues.
Update the kernel on the smartphone (for advanced):
On some Xiaomi devices (e.g, POCO F1 Or Redmi Note 10 Pro, you can install a custom core (e.g., FrancoKernel) that optimizes the network stack:
- Unlocked bootloader (bootloader).
- Superuser rights (root).
- Experience with TWRP and ADB.
8.Extreme measures: factory reset and equipment replacement
If none of these methods work, there are radical solutions left, and only use them after a full diagnosis!
Reset smartphone to factory settings:
This will delete all the data, but it will return the network parameters to their original state.
Make a backup copy (through Settings) β Additionally. β Backup)
Record passwords from Wi-Fi and accounts
Make sure that the smartphone has enough charge (at least 70%)
Get out. SIM-card and memory card (if any)-->
For discharge:
- Settings β About the phone β Reset settings β Reset all settings.
- Confirm the action and wait for the reboot.
Replacement of router or smartphone:
If the hardware is outdated (for example, the Xiaomi Mi Router 3 2016 router or the Redmi smartphone) 4X), It may not be up to date with the current requirements:
- π‘ Router: If he doesn't support it 802.11ac (Wi-Fi 5) or MU-MIMO, It's time to change.
- π± Smartphone: If it doesn't support 4G+ (Carrier Aggregation or 5G, a) the operator shall provide such networks.
Choosing the new Xiaomi router:
