Modern Xiaomi smartphones, which are based on the shell MIUI or HyperOS, have powerful hardware, but users often face unreasonably low data rates, this can occur for a variety of reasons, from software failures in the modem to incorrect network settings laid down by the operator. When video stream slows down and pages load eternity, there is an urgent need to optimize the system.
In this article, we will discuss the most efficient and secure ways to significantly improve mobile connectivity performance, touching on both standard methods available to each device owner and more advanced techniques that require caution. Deep network settings often work wonders to restore the comfort of using a gadget.
Before you start to do complex manipulations, you should rule out the trivial problems with covering or overloading the operator's towers. However, if the Internet flies in the next device, and your Redmi or Poco barely crawls, the problem lies in the configuration of your device. Let's move on to specific actions.
Diagnostics of the current state of the network
The first step is always to make an objective assessment of the situation, not just to rely on subjective sensations of page loading speed, but to use specialized tools to measure incoming and outgoing traffic, as well as ping, which will allow you to capture the initial indicators before and compare them with the results after setting.
There are many applications for testing, but the most reliable results are from Ookla Speedtest or Fast.com. It is important to take measurements at different times of the day and in different locations to eliminate the factor of temporary congestion of the cell tower: 4G (LTE) or 3G, The optimization methods may differ for them.
Now, if you're in a secure reception zone, but your phone is persistently holding 3G or H+, you're not prioritizing the networks correctly. In some cases, it helps to just reboot the communication module, but we'll talk about that later, and the key is to understand whether the problem is hardware or software.
⚠️ Note: Test results can vary greatly depending on the remoteness of the verification server. Always choose your operator's server or the nearest major city for the correct data.
Basic actions for reloading modules
Often, the Internet is unstable because of accumulated software errors in modem drivers. Simply turning on and off flight mode can force a device to reconnect to the nearest and less busy base station, the fastest way to shake up a connection without deep interference.
To perform this procedure, lower the notification curtain and activate the Flight Mode icon. 10-15 So you have to take a second to shut down the communication module completely, and then you deactivate the mode, and then the system re-registers on the network, and you get a fresh update. IP-Address and update the connection, and in most cases, it helps if the speed drops sharply and unexpectedly.
If the flight mode switch fails, try resetting the network settings, which will return all Wi-Fi, Bluetooth and mobile data settings to factory values. You will have to re-enter passwords from wireless networks, but this often resolves configuration conflicts.
☑️ Checklist of rapid diagnosis
Remember that a smartphone reboot is not just a screen shutdown, but a complete reboot of the Android operating system. It clears RAM and completes the hanging processes that can block network traffic. Regularly restarting the device at least once a week is a good habit for maintaining the health of the system.
Setting up APN access points
One of the most effective techniques is manually adjusting APN (Access Point Name) access points. Operators often prescribe standard settings that may not be optimal for your region or a particular smartphone model. Creating a new access point with modified parameters can significantly reduce ping and increase throughput.
To enter the settings menu, go on the Settings path → SIM-maps and mobile networks → Choose yours. SIM → Access points (APN). Here you'll see a list of existing profiles. Don't edit them directly, you'd better create a new one by clicking on the plus or the button "New AP." In the Name field, type in any name, like Fast Internet, and in the Access Point field, type in the "Name" field (APN)» Enter the address provided by the operator (usually the Internet).
The key is to change the protocol type. Find the APN type and make sure it says default, supl, or just default. In some cases, changing the APN type to IPv4/IPv6 helps. It's also worth trying to change the Network Type option to LTE or LTE/TD-SCDMA/GSM if such options are available in your firmware version.
| Parameter | Recommended value | Description |
|---|---|---|
| Name. | Custom Fast | Arbitrary profile name |
| APN | internet | Main address of operator's gateway |
| Protocol | IPv4/IPv6 | Priority protocol stack |
| Type APN | default,supl | Types of supported connections |
After making all the changes, make sure to keep the new profile and choose it active. Then it is recommended to turn on the flight mode for 10 seconds and turn it off so that the network reconnects with the new parameters. If the Internet stops working, return the default settings - not all operators support manual modifications.
⚠️ Attention: Incorrect settings APN This can cause a total loss of mobile internet. Take a note or a photo of the initial values before making changes so you can roll back.
Shift. DNS-servers to speed up response
Standard. DNS-servers that are automatically issued by the carrier are often overloaded or slow to process requests for domain name permission, replacing them with public and fast servers such as Google. DNS Cloudflare, or Cloudflare, can significantly speed up the opening of sites, especially those that are saturated with advertising and trackers.
In modern versions of Android and shell MIUI You can do this without getting root permissions. → Connection and sharing → Private DNS. The default is "Auto" or "Disabled." Select "Host Name of the provider" DNS» and enter the address dns.google or 1dot1dot1dot1.cloudflare-dns.com.
This setting applies globally to all connections, including Wi-Fi and mobile internet. DNS It also encrypts your requests by adding a privacy layer, as the provider will not be able to see which sites you visit, although it is not possible to do so. IP-The addresses will still be visible.
Does it work on older Android?
It’s worth noting that changing the DNS does not increase the physical speed of the channel provided by the operator, but reduces the response time when navigating. Sites begin to “drawn out” faster, delays disappear before starting to load content, this is especially noticeable on tariffs with high baseline speed.
Use of engineering menus and hidden codes
For advanced users, there is access to a hidden engineering menu where you can forcibly switch your smartphone to network-only mode. 4G/LTE. This prevents the device from being “rolled” into 3G In areas of unstable coverage, where the phone convulsively tries to catch the signal, losing data packets.
To get to the menu, open the Phone app and dial the code ##4636##. If the code is not working (on some global firmwares, access is closed), you can use the Activity Launcher app to find hidden activity "Testing". From the menu that opens, select "Phone Information".
Find the option “Set preferred network type” (Set preferred network type). By default, there may be a mixed mode, such as LTE/TD-SCDMA/GSM. Try to choose the LTE Only option. After that, the phone may lose voice communication (if VoLTE is not enabled), but the Internet speed will become stable, as the device will stop looking for other types of networks.
💡
Remember to return your network settings to their original state before important calls if LTE Only blocks voice communication in your region without VoLTE technology.
Using LTE Only also has a positive effect on the autonomy of the device, since the communication module stops constantly scanning the air for 2G/3G networks. However, in areas where 4G coverage is not available, the Internet will simply disappear, so use this feature wisely.
System optimization and garbage disposal
Background processes and bloated application cache can indirectly affect Internet speed, putting strain on the processor and data channel. MIUI has built-in cleaning tools, but sometimes a deeper approach is required. Removing unused applications frees up resources for system services responsible for the network.
Check the list of applications that have access to background data. Go to Settings → Applications → Traffic Management. Here you can prevent background activity for programs that do not need a constant connection (for example, games or photo editors), This will free up a channel for the browser and the navigator.
Also worth paying attention to the “Game Acceleration” feature or similar game modes, which can be activated constantly, which redistribute system resources in favor of an active application, limiting background synchronization and updates, which can positively affect ping in online games.
💡
Regularly cleaning the cache and limiting the background activity of “heavy” applications is an easy way to free up system resources for faster network operation.
Don’t forget to update your system software. Xiaomi engineers regularly release patches that fix modem errors and improve compatibility with the networks of various operators. Check for updates in the Settings → About Phone → MIUI version.
