Modern Xiaomi smartphones are famous for their speed and rich functionality of the shell MIUI or HyperOS. However, even the most powerful processor and top-end communication module can be powerless in the face of a slow or unstable Internet connection. Users often face a situation where pages load for a long time, video hangs on buffering, and online games become unplayable due to high ping.
The reasons for low Internet speed can be very different, from the banal overflow of cache of network services to incorrect settings of the provider or the physical location of the router. In this article, we will discuss in detail what system parameters affect the quality of the connection and how to optimize them correctly without installing third-party software.
Don't just go to the hardware of a device, and most of the time, it's software conflicts or outdated network configurations, and fine-tuning can do wonders, turning barely creeping traffic into a steady stream of data that's necessary for a comfortable experience and entertainment.
Diagnosis and analysis of the current compound
Before making changes to deep system settings, you need to understand the real picture of what is happening. Often users confuse the speed of downloading a file with the real bandwidth of the channel.
Pay attention to the status bar indicators. If you see a 4G icon instead of LTE+ or 5G, this is the first signal that the device is not using the available network potential, it is also important to check whether there are applications running in the background that actively consume traffic, such as cloud storage or messengers with auto-save media.
⚠️ Warning: Before performing any manipulation of network settings, make sure you have access to the restore point (such as a known Wi-Fi password or enabled mobile data) so that you don’t lose touch with the outside world during the setup process.
There are several key metrics to look at when diagnosing: Ping is critical for online gaming, Download is important for streaming, and Upload is necessary for video calls and file sending.
Optimizing Wi-Fi settings on Xiaomi
Wireless is the most common way to access the network, but it is also the most prone to interference. Xiaomi smartphones have several hidden and explicit settings that can significantly improve signal stability.
First of all, you need to check the frequency range. Modern routers work in the 2.4 GHz and 5 GHz bands. If your router is dual-band, be sure to switch your smartphone to a 5 GHz network. It provides higher speeds, although it has a smaller range compared to 2.4 GHz.
- 📡 5GHz Range: Perfect for gaming and viewing 4K-video near the router, less susceptible to interference from household appliances.
- 🏠 2.4 GHz range: Better at breaking through walls, but often "clogged" with neighborhood nets and microwaves, which reduces speed.
- 🔒 Security: Make sure that the encryption protocol is used WPA2/WPA3, Older protocols can limit connection speeds.
Also in Xiaomi's Wi-Fi settings, you should turn off the Wi-Fi Assistant feature if it's not working properly. Sometimes it tries to switch you to mobile internet at the slightest signal weakening, creating an illusion of instability. Go to Settings → Wi-Fi → Wi-Fi Assistant and experiment with sensitivity thresholds.
💡
Use the Wi-Fi Analyzer app (or analog) on another device to find the least loaded channel for your 2.4GHz network and set it in your router settings manually.
Configure DNS to speed up response
One of the most effective ways to increase the speed of the Internet on Xiaomi is to change the Internet. DNS-By default, your smartphone uses servers. DNS-These are often overloaded or slow to process requests, which leads to a long “promotion” of pages before starting to load content.
Using public DNSs from major technology companies like Google or Cloudflare will speed up the process of resolving domain names, which will not increase the physical speed of the channel, but will make navigation on the network noticeably more responsive.
To change your settings, go to Settings → Connection and Sharing → Private DNS. Here, select the option “Host Name of a Private DNS Provider” and enter the address of one of the fast servers. For example, for Cloudflare it is 1.1.1.1, and for Google it is dns.google.
| DNS Provider | Main address (host) | Features | Recommendation |
|---|---|---|---|
| Cloudflare | 1.1.1.1 | High speed, focus on privacy | Recommended for games |
| Google Public DNS | dns.google | Stability, Global Infrastructure | Universal choice |
| Quad9 | dns.quad9.net | Blocking malicious sites | For enhanced security |
| OpenDNS | dns.opendns.com | Flexible content filtering | For parental control |
Once you enter the address, click Save. If the internet stops working, return the setting to Auto or Disconnected. In some cases, providers block third-party DNS, but this is rare.

Reset network settings and APN
If software failures accumulate, standard optimization techniques may not help, and in such cases a radical solution is required: resetting network settings, which will return all connection parameters to factory values, removing possible configuration conflicts.
It's important to understand the difference between completely resetting your phone and only resetting your network. The second option is secure for your personal data: photos, contacts and apps stay in place, only saved Wi-Fi passwords, Bluetooth devices and mobile network settings are deleted.
To do this, go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Confirm and wait for the communication modules to reboot. After that, re-enter the password from your Wi-Fi network.
⚠️ Note: After resetting your network settings, you will have to re-authorize on all your stored Wi-Fi networks and re-connect your Bluetooth headset or watch. Make sure you remember passwords from important access points.
Special attention should be paid to the settings of the access point (APN) Sometimes the providers change the settings, and the phone stays old. → SIM-maps and mobile networks → Access points (APN). If the list is empty or the settings look odd, click the menu button (three dots or “More”) and select Reset to default settings».
Hidden engineering menus and modem modems
There are engineering menus in the MIUI shell and Android operating system that allow you to manage network priorities, an advanced level of customization that can help lock a phone into a faster communication standard, such as forcing LTE or 5G on if the device is constantly “jumping” on 3G.
To enter the test menu, enter the phone number ##4636##. The Test menu will open. Select Phone Information. Here, in Set up your preferred network type, you can select LTE Only (4G only) mode.
Using LTE Only has its pros and cons. On the one hand, the phone stops wasting time searching and switching between 2G/3G, which stabilizes ping. On the other hand, in areas of poor coverage, you can completely lose voice communication, as for calls without VoLTE, the phone will try to switch to 3G, which is prohibited in this mode.
What to do if your voice is missing in LTE Only?
It’s also worth checking if the traffic saving mode is enabled, which can artificially limit the background activity of applications, located in the Settings section → Connection and Sharing → Data Transfer → Traffic Savings.
The Effects of System Limitations and Background Processes
The Android system on Xiaomi smartphones aggressively manages battery resources, which sometimes negatively affects the background data load. If the application “falls asleep”, it may not receive current data, creating a feeling of slow Internet when opened.
You need to configure exceptions for important applications. Go to Settings → Applications → All applications, select the desired messenger or browser, go to Battery and set the No Limits mode. This will allow the application to maintain an active network connection at all times.
- 🚀 Cache Clearing: Clean up the cache of your browser and Google Play system services regularly, as a crowded cache can slow down the processing of network requests.
- 📱 Background Processes: Check the list of running apps and close the ones you don’t need right now, especially heavy gaming or navigators.
- 🔄 Auto Updates: Disable automatic app updates via mobile in the Google Play Store and GetApps settings.
Another important aspect is screen time and sync, and if account sync is stuck because of an error, it may be constantly trying to send data, putting a strain on the channel. Check the sync status under Accounts and Sync.
💡
Integrated approach to setup: The combination of the right DNS, network reset and background control gives a more noticeable result than changing a single parameter.
