How to Improve the Quality of the Internet on Xiaomi: A Complete Guide

Owners of Xiaomi, Redmi and Poco smartphones often face a situation where the device shows complete network division, but pages in the browser load agonizingly long. The problem lies not only in the operator’s tariffs or router power, but also in the specific settings of the MIUI or HyperOS shell. The system can aggressively save energy by disabling communication modules, or use suboptimal DNS parameters for your region.

The solution is a complex approach, from simple reboots to deep-tuning engineering menus. In this article, we will explore proven methods that will help you speed up the Internet and make the connection stable. We will touch on both the software aspects and the physical features of signal reception in modern gadgets.

Before we go into complex manipulations, we need to rule out the obvious causes of failures. The most common cause of unstable work is the conflict of static problems. IP-Make sure that your router does not have a situation where two devices are trying to occupy the same address, and it is also worth checking whether the traffic limit is not exhausted, since some operators slow down after reaching a certain threshold.

⚠️ Note: Before making changes to the access point settings (APN) Make sure to take a screenshot of the current settings or write them down, which will allow you to quickly restore access to the network if the new values are incorrect for your operator.

Diagnostics and primary network settings

The first step should always be to diagnose correctly. Don’t go straight to hidden menus if the problem is solved by simply changing the mode of operation of the communication module. Xiaomi owners have access to an extended statistics menu where you can see the real connection speed and signal level in decibels (dBm), rather than in conditional sticks.

For accurate signal quality data, go to Settings → About Phone → All specs → Usage Statistics (the path may vary depending on the version of MIUI). Here you will see details on Wi-Fi and mobile data. If the LTE signal level drops below -110 dBm, the problem is most likely physical: you are in a poor coverage area or the smartphone body blocks the antenna.

Automotive mode sometimes mistakenly switches your phone to 3G or Edge in areas of unstable 4G coverage. To lock in the standard, open the engineering menu by typing in the "ringer" code ##4636##. Select "Phone Information" and in the "Set up your preferred network type" field select LTE only or LTE/TD-SCDMA.

• 📶 Check the signal level in dBm: the values are closer to 0 better than -120.
• 🔄 Reboot the communication module via flight mode: turn on for 10 seconds and turn off.
• 📱 Make sure the cover does not contain metallic elements shielding the antenna.

Using the code ##4636## gives you access to the test menu, where you can not only select the type of network, but also run the Ping test. This helps determine whether the delay is on the operator side or when transferring data packets. If the ping to the Google server is high, it makes sense to change the ping to the Ping server. DNS-server.

Optimization of Access Point Settings (APN)

Setting up an APN is one of the most effective ways to speed up mobile internet on Xiaomi smartphones. Communications providers often provide standard settings that may not take into account the specifics of work in your region or the current load on base stations. Creating your own APN profile allows you to bypass some of the provider’s limitations.

To enter the settings menu, go on the Settings path → SIM-maps and mobile networks → Choose yours. SIM → Access points (APN). Click the “New Access Point” button or icon «+». Here you need to enter data provided by your operator, which is easy to find on the official website.

In the APN type field, it is best to prescribe default,supl,dun. dun allows you to use the phone as a modem without restrictions, and supl speeds up location determination via satellites. The protocol preferably set IPv4/IPv6, since many modern services have already moved to the new addressing standard, which can positively affect the response speed.

After saving a new profile, make sure to select it by placing a marker next to the name. Then it is recommended to turn on the flight mode for 5-10 seconds to re-register the network with new parameters. If the Internet is lost, check the correct spelling of the APN address - the register of letters is usually not important, but spaces are not allowed.

⚠️ Note: Do not delete standard profiles APN, Leave them as a backup option in case your manual settings stop working after the firmware update.

Wi-Fi Acceleration: DNS and Frequency Ranges

Wi-Fi problems on Xiaomi are often associated with incorrect work DNS-servers of the provider or congestion of the channel. DNS Google or Cloudflare can significantly reduce the response time in games and speed up the opening of sites. This is especially true if the provider uses congested name servers.

In modern versions of MIUI and Android, you can write DNS for each Wi-Fi network separately. Go to the Wi-Fi settings, click on the arrow or gear icon next to your network. Find the "IP settings" item and switch it from "DHCP" to "Static." In the fields "DNS 1" and "DNS 2" enter the addresses: 1.1.1.1 and 8.8.8.8.

Another important aspect is the frequency range. Routers support 2.4 GHz and 5 GHz. 2.4 GHz is more long-range, but is heavily noisy by neighbouring routers and Bluetooth devices. 5 GHz provides high speeds, but worse passes through walls. If you're in the same room with a router, force your smartphone to connect to a 5 GHz network.

• 🚀 Use it. DNS 1.1.1.1. for maximum response speed.
• 📡 Connect to 5 GHz if you are close to the router.
• 🔒 Avoid channels 1, 6 and 11 at 2.4 GHz if they are busy with neighbors.

Also worth noting is the Wi-Fi Assistant feature in smartphone settings, which allows the phone to automatically switch to mobile internet if the Wi-Fi signal becomes too weak, preventing the phone from hanging on dying Wi-Fi instead of using fast 4G.

Resetting network settings and cleaning the cache

Errors in network configurations are a common reason why Xiaomi's Internet is starting to get unstable, and over time, old Wi-Fi profiles, erroneous routing, and conflicting hosts records accumulate in the system. A complete reset of network settings returns communication modules to factory status.

This operation can be performed via the Settings menu → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Please note that this procedure will remove all saved passwords from Wi-Fi networks and associated Bluetooth devices. However, it will not affect your personal files, photos or applications.

adb shell pm clear com.android.providers.downloads

In addition to system reset, it is useful to clear the cache of system services responsible for downloads. This can be done through the application menu by finding Downloads or Download Manager, and selecting Clear Cache. In some cases, cleaning the cache of the Google Play service helps, since it actively uses the background connection for updating.

💡

Network reset is a “nuclear” method that solves 90% of software connection problems, but requires re-entering passwords from Wi-Fi.

After the reset, the phone will restart, and in the first few minutes, the system will re-register in the operator's network and scan the surrounding Wi-Fi networks, at which point there may be temporary instability, which will pass in 2-3 minutes, and if the problem persisted from the failure, now it should disappear.

Hidden MIUI Functions and System Optimization

The MIUI shell and the new HyperOS have an aggressive energy saving system that can limit the background activity of network modules. To improve communication, you need to configure battery performance for network applications. Go to Settings → Battery → Settings and make sure that you do not turn on extreme energy saving mode when you do not need it.

It’s also worth checking your settings for specific applications. If you only have a bad Internet experience in one program (like Telegram or Instagram), go to Settings → Apps → All Apps → [App Name] → Battery and select No Limits mode, which will allow the app to maintain a permanent connection without interruption by the system.

In the engineering menu (#4636###), there is another useful feature called “Running Ping Verification” that allows you to test the connection to various servers. If the test shows a packet loss (Packet Loss) of more than 1-2%, this indicates a problem on the provider side or physical damage to the antenna module of the phone.

• 🔋 Turn off energy saving for messengers and navigators.
• 🧹 Clean the cache regularly through the Security app».
• 📲 Update the Google Play Services component through the Play Market Store.

Remember that a phone's overflowing memory can also indirectly affect network speed: When the system partition is full, the operating system lacks the resources to buffer network packets, and try to keep at least 10-15% of the total internal memory free.

⚠️ Warning: Do not use “Internet accelerators” from third-party app stores. at best, they are useless, and at worst, they show ads and collect your data, further straining the system.

Hardware factors and operator choice

No amount of customization will help if the problem is hardware or lack of coverage. Xiaomi’s budget and mid-range smartphones often feature modems that support Carrier Aggregation only in theory or in a limited number of combinations, which means that the phone may not be able to combine multiple frequency bands to improve speed.

You can check your model's supported bands on specialized sites, knowing the exact model of the processor and modem. If your carrier uses predominantly the B7 (2600 MHz) band in your area and the phone does not catch it well, no magic with APN will work, in which case only a change of operator or use of an external antenna amplifier will help.

💡

Use apps like NetMonster or CellMapper to see which base station your phone is connected to and at what frequency, and help you understand why speeds drop in certain places.

Also, consider the physical condition of the device: smartphone crashes could have caused antenna plumes to unplug or micro-cracks on the board. If the phone started catching the network much worse after the fall than before, even with a full signal, there is a likely hardware malfunction that requires a visit to the service center.

In conclusion, improving the quality of the Internet on Xiaomi is a process of adjusting to specific operating conditions. Start with simple steps like changing the DNS and checking the APN, then move on to resetting, only if these methods do not help, you should think about changing the operator or repairing the device.
