How to speed up the Internet on Xiaomi: a complete guide

Slow page loading and video buffering are common companions for Xiaomi smartphone owners who over time begin to notice a decrease in connection speed. The problem can be either in the crowded cache of system applications, or incorrect DNS settings or communication module failures. Owners of Redmi and Poco devices often find that even with a powerful router signal, the real data rate drops to minimal values.

Making matters worse, the MIUI or HyperOS shell has many background processes that can consume traffic without the user’s knowledge. Before blaming the provider or buying a new router, it’s worth doing a deep diagnostic of the smartphone itself. In this article, we’ll discuss effective methods to help stabilize the connection and get the most out of your plan.

It is worth starting with a basic analysis of the current situation, since blind application of settings may not give a result if the cause lies in physical damage to the antenna or wear and tear. SIM-Diagnostics is the first step to solving a problem that allows you to weed out software errors from hardware malfunctions.

Diagnostics of current connection and identification of problems

The first step is to understand where packet loss occurs, on the operator side or inside the smartphone's local network. Use built-in tools or third-party tools to measure ping and speed. Run the test at different times of the day to eliminate the impact of the load on the provider's network during peak hours.

Note the indicators in the status bar: if E or G is displayed instead of 4G or 5G, then the phone is running in EDGE mode, which is physically unable to provide high speed. In the mobile network settings, force the LTE preference mode to prevent the device from trying to switch to outdated communication standards.

⚠️ Note: If the network indicator is constantly jumping between 3G and 4G, This may indicate poor reception in your location or problems with the location itself. SIM-Try to remove and wipe the chip contacts.

For more detailed analysis, you can use the engineering menu, available through a special code set in the Phone app. Type ##4636## to get into the testing section. This shows the real strength of the signal in dBm: values closer to -50 mean a great signal, and below -100 - a very weak one.

Optimization of Wi-Fi Module settings

Wireless connectivity often suffers from channel interference, especially in apartment buildings. Go to your router settings and try changing the broadcast channel to a less busy one (usually 1, 6 or 11 for the 2.4 GHz band). On your smartphone, go to Settings → Wi-Fi → Wi-Fi settings and make sure that the option “Use Wi-Fi even in sleep mode” is enabled.

Signal frequency is an important parameter. If your router supports dual-band, be sure to connect to a 5GHz network. This range provides significantly higher data rates and is less susceptible to interference from microwave ovens and bluetooth devices, although it has a smaller range.

• 📶 Turn off the Wi-Fi Assistant feature, which can automatically switch you to mobile internet at the slightest signal drop, causing connection breaks.
• 🔒 Check the type of encryption: use it WPA2/WPA3, Older protocols can limit speed and create vulnerabilities.
• 📡 Reset your network settings on your phone if the problem occurs after a firmware update or router change.

💡

Place the router at a height of at least 1.5 meters and away from mirrors or metal objects that shield the signal.

Remember that the accumulated DNS cache can also slow down the opening of sites. In the Wi-Fi settings, click on your network name and find the DNS field. Change the automatic settings to manual ones by writing server addresses 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google), which often speeds up server response.

Setting up mobile network and APN access points

When Wi-Fi is unavailable, the main communication channel becomes the mobile Internet (APN) — One of the most common causes of low speed on Xiaomi. → SIM-maps and mobile networks → Choose. SIM → Access points (APN).

You need to create a new hotspot or edit an existing one. Make sure the APN type field spells out default,supl or just default. Incorrect MCC and MNC settings can cause the phone to run on a 2G/3G network, even if the 4G coverage is excellent.

Name: Operator Fast


APN: Internet (or operator value)




APN Protocol: IPv4/IPv6




Type of authentication: PAP or CHAP

⚠️ Attention: After changing the settings APN be sure to restart the device and turn on the flight mode for 10 seconds to re-register on the network.

It’s also worth checking if Traffic Saving mode is activated for background apps, a feature that’s useful for saving money, often blocking notifications and updates from getting timely, creating the illusion of slow internet, and disable it for messengers and navigators in the Data Control section.

Resetting network settings and cleaning the cache

If software failures accumulate, the only correct solution is to completely reset the network settings, which will return all settings of Wi-Fi, Bluetooth and mobile communication to factory values.

To perform the reset, go along the Settings path → Connection and sharing → Reset Wi-Fi, mobile networks and Bluetooth, confirm the action and wait for the reboot of communication modules, which helps to eliminate conflicts. IP-Addresses and routing errors within the Android system.

In parallel, clear the cache of the Downloads system application and browser. Go to Settings → Apps → All applications, find the browser and click Clear Cache. Don’t confuse it with the Clear Data button, as this will delete the history and saved logins.

Disabling background processes and limitations

MIUI is known for aggressive battery optimization, which can artificially limit background activity of network modules, check battery settings for key applications and set the No Limits mode, allowing applications to fully utilize the network resource.

It's also worth disabling Adaptive Connection if it's active, which is an algorithm that tries to analyze network quality and can mistakenly switch data streams, leading to spurts in streaming or online gaming, and stability is more important than the system's attempts to guess the best channel.

• 🚫 Turn off gallery and cloud sync when you need top speed for other tasks.
• 📉 Check the list of apps consuming traffic in the background and deny network access for suspicious or unnecessary programs.
• ⚙️ In developer mode, you can find the option “Wi-Fi Aggregation”, but turning it on requires support from the router and can, on the contrary, destabilize the connection on older models.

Often the cause of the “brakes” are heavy app updates in Google Play or GetApps. Install app updates only via Wi-Fi so that the background process does not clog the channel at an important moment.

Hardware factors and equipment selection

You can't discount the physical condition of the device. If the smartphone fell or was exposed to moisture, the antenna module could move away from the contacts. In such cases, the software settings are useless, you need to disassemble and check the plumes in the service center.

Age also plays an important role. SIM-If you use the SIM card more than 5 In the years since, her contacts may have worn out and her safety standards may have become obsolete. SIM-new card with support USIM and 4G/5G Profiles often do wonders with mobile internet speed.

⚠️ Warning: When buying covers, avoid models with metal inserts or magnetic locks on the back – they can shield the signal of antennas located at the top of the case.

💡

A comprehensive approach that includes changing the DNS, setting up the APN and choosing the right Wi-Fi range solves 90% of the speed problems on Xiaomi.

If you use an old router that was released more than 7 years ago, it may not be able to cope with modern tariff speeds and the number of connected devices, in which case, you can not accelerate the Internet on your smartphone without replacing the router with a model that supports AC or AX (Wi-Fi 6).
