How to speed up the Internet on Xiaomi phone: proven ways

Modern Xiaomi, Redmi and Poco smartphones have a powerful hardware, but even flagship models sometimes face the problem of slow connection, which can manifest itself in long loads of pages, video buffering or breaks in calls through instant messengers. Often the cause lies not in the provider, but in software failures or incorrect settings of the device itself, which are easy to fix yourself.

In this article, we will discuss a comprehensive approach to solving the problem: you will learn to diagnose network bottlenecks, change system parameters to maximize throughput, and use hidden features of the MIUI or HyperOS shell. The right configuration can increase the real data rate by many times, especially in areas of uncertain signal reception.

Before you go to complex manipulations, you need to eliminate trivial factors: check the balance of the SIM card, make sure that the account has funds and does not exhaust the traffic limit. It is also worth rebooting the router if the problem is observed in the home Wi-Fi network. Sometimes a simple page update or restart the application is solved by temporary glitches.

Diagnostics of current connection and frequency selection

The first step is always to make an objective assessment of the situation: Don't rely on the subjective feeling of "slowly", use measurement tools. Built-in testers or third-party applications will show the real speed of Download and Upload, as well as ping. If the rates are significantly lower than the declared tariff, the problem requires intervention.

A critical parameter for Xiaomi owners is the choice of Wi-Fi range. Most modern routers operate in two bands: 2.4 GHz and 5 GHz. The 2.4 GHz range has a longer range, but is highly susceptible to interference from neighboring networks and household appliances. The 5 GHz range provides much higher speed and stability, but worse penetrates walls.

If your phone is close to the router, forced switching to 5 GHz is the most efficient way to speed up the internet. Xiaomi's Wi-Fi settings often display two networks with the same name but with the label "5G" or just a different name if you've manually set them on the router. Connect to the 5 GHz network for streaming and gaming.

The situation is different for mobile networks, so it's important to check what modem is running.

Shift. DNS-servers to speed up response

One of the most effective, but often ignored methods is the change of the DNS-By default, your phone uses servers. DNS-Addresses provided by a carrier or Internet provider can be overloaded or slow to process requests, resulting in a long page “promotion” before content loads.

Using public DNS from Google or Cloudflare allows you to speed up response time (ping) and bypass some blocking or routing errors of the provider. This is especially true for games and messaging calls, where every millisecond matters. On Xiaomi smartphones with Android 9 and above, this setting can be done without root rights through the system menu.

To perform the settings, go to Settings, then select Connection and Sharing (or “Wi-Fi”). DNS (Private DNS). The default is "Auto." Select "Host Name of the provider" DNS» (or “Manually”) and enter the address of a trusted server.

dns.google

Alternatively, Cloudflare offers:

1.1.1.1

Once you enter the address, click Save. Changes take effect instantly, and you may notice that pages start to pop up in a jerky fashion, without waiting, and that's what the fast DNS does.

💡

If after changing the DNS, some local sites or operator resources stopped opening, return the setting to the position "Auto" or "Off".

It's worth noting that DNS doesn't increase the maximum download speed, but it does speed up the navigation of websites. This is a critical difference to understand. For downloading heavy files through torrent, channel bandwidth is more important, and for surfing, domain name resolution speed is more important.

Reset network settings and flight mode

If software failures accumulate, the communication module may not work correctly. Android and the MIUI shell have a network reset function that does not delete your personal data, photos or contacts, but erases stored Wi-Fi passwords, Bluetooth device settings and mobile network settings.

This procedure returns the network stack to factory status, eliminating configuration file conflicts, often helping in cases where the phone "sees" the network but can't get it. IP-address or permanently lose connection. The path to function is usually in the Settings section → Connection and sharing → Reset Wi-Fi, mobile networks and Bluetooth.

☑️ Checklist before network reset

Remember passwords from important Wi-Fi networksMake sure you have internet on other devicesCheck the SIM card balancePerform a reset in the settings menu

Done: 0 / 4

A more radical but quick method is to completely reset the radio module through flight mode. Turn on Air Mode for 10-15 seconds, and then turn it off. This forces the phone to re-register in the operator's network and reconnect to the nearest cell tower, selecting the optimal channel.

⚠️ Warning: Once you reset your network settings, you'll have to re-enter passwords from all Wi-Fi networks and re-connect your Bluetooth headphones or watches.

Also, in the Android hidden engineering menu (not available on all models), you can try resetting your network preferences. To do this, you type in the dialer code ##4636##. If the menu opens, select Phone Information and click Run Ping Test or try to switch the network type to reset your current connection.

Optimization of MIUI and background processes

The MIUI shell is known for its aggressive work with background processes, which is usually good for the battery but sometimes interferes with the stability of the connection. Some applications can "strangle" background data transfer, thinking that you save charge, or vice versa, constantly request updates by clogging the channel.

Check your traffic savings settings. Go to Settings → Apps → Traffic Management. You can see which apps consume the most data. If you see an unknown app that eats gigabytes, it should be removed or restricted.

In addition, Wi-Fi settings have a feature called “Use Wi-Fi in Traffic Saving Mode” (or similar wording depending on the version of MIUI) to make sure it’s turned off.This mode limits background activity and can result in messengers not receiving messages on time while the screen is off.

The Developer's Secret Setup

In the Developer Menu (click on the MIUI version 7 times in About Phone), look for Agent Wi-Fi Proxy. Make sure it says No. Sometimes it lists third-party addresses that block the connection.

Also worth noting is the Wi-Fi Assistant feature, which allows your phone to use mobile internet if the Wi-Fi connection is unstable, and in some cases, enabling this feature helps avoid complete disconnections, although it consumes SIM card traffic.

Comparison of optimization methods

To make it easier for you to choose your strategy, we have systematized the basic methods and their effectiveness in different scenarios. Not all methods are the same: somewhere you need a comprehensive approach, and somewhere you need one action.

Method	Efficiency	Difficulty	Impact on data
Changing the DNS	High (for web surfing)	Low.	Safe.
The 5GHz transition	Maximum	Low.	Safe.
Resetting network settings	Medium (when failures)	Medium	Requires password entry
Engineering menu	Variable	Tall.	Risk of error

As you can see from the table, going to 5 GHz gives the greatest increase in physical speed if the router supports this standard, but if the problem is in the software sticking the module, only a complete reset of network settings will help to restart the connection process.

And the physical factor is that cases with metal inserts or magnetic rings for holders in the car can shield the antenna of the smartphone. If you notice that the speed drops in a particular case, try removing it and checking the connection again.

Frequent Questions and Challenges (FAQ)

Why is the Internet running slowly on Xiaomi in some applications?

The most likely problem is the traffic saving settings for a particular application or in the cache of the application itself. Go to Settings → Apps, find the problem program, select Traffic Savings, and select No Limits. Also clear the app cache.

Does a phone’s overcrowded memory affect internet speed?

Yes, indirectly. If the memory is critically filled (less than 500 MB left), the system is slow, processes freeze, and the browser or applications do not have time to process incoming data, creating the illusion of slow Internet. Make room for stable operation.

Should you use accelerators from the Play Market?

In most cases, no. Applications like Internet Booster often simply clean the DNS cache or turn on/off the air mode, which you can do yourself, and in fact, they can contain ads and consume resources themselves, slowing down the phone.

What if 4G is missing after MIUI update?

Check the access point settings (APN). Sometimes, after the update, the operator's parameters are lost. → SIM-maps and mobile networks → select a SIM card → Access points (APN). Click the menu (three dots) and select Reset to defaults».

Can a virus slow down the internet on your phone?

Yes, malware can use your communication channel to mine or send spam, which greatly reduces speed.Scan your device with built-in security antivirus or install a reliable third-party scanner.
