Accelerating the Internet on Xiaomi Redmi 8: an expert guide

Many owners of the Xiaomi Redmi 8 smartphone face a situation where the device begins to slowly load pages or buffer videos for a long time, especially when the hardware of the phone is quite comfortable to work on the network. Often the problem lies not in the physical wear of the communication module, but in the software limitations or incorrect settings of the MIUI system.

In this article, we’ll look at proven methods to help you get the most out of your connection. You’ll learn how to set up access points correctly, what hidden Android settings are worth changing, and how background processes can eat up all traffic. Network optimization is the first step to stable operation.

Before you go to complex manipulations, you should rule out the trivial reasons: check the balance with the operator, make sure that there are no scheduled work on the tower, and restart the router if you use Wi-Fi. If the basic actions did not help, move to deep configuration.

Current speed analysis and problem diagnosis

The first step is always to make an objective assessment of the situation, not just to rely on the subjective sense of the brakes, but to use specialized tools to measure ping, load and recoil, which will allow you to understand exactly where the bottleneck lies.

Run the test in Speedtest by Ookla or similar. Not only do you look at megabits, but you also look at Ping, which is a high ping that often causes lags in games and heavy sites to open long-term, even if the download speed is formally high.

• 📶 Check the signal level at different points in the room – walls and appliances can screen the signal.
• 📱 Turn it off. VPN Proxy servers, if they are active, as they significantly reduce speed.
• 🔄 Reboot your smartphone to reset temporary network errors and cache DNS.

If the rates are significantly lower than the stated tariff, the problem may be on the provider’s side, but if the neighboring devices are at normal speed, then it is the settings of the Redmi 8 itself.

Configuring APN access points for mobile Internet

One of the most effective measures to speed up mobile internet is manually configuring APN (Access Point Name) access points. Operators often use standard settings that may not be optimal for your region or current network load.

To make changes, go to the Settings menu → SIM-Maps and mobile networks. Select your SIM card, then press Access Points (APN). In the upper right corner, click the plus to create a new point, or edit an existing one.

⚠️ Warning: Before changing the settings, write down or take a picture of the original values, which will quickly return everything as it was, if after editing the Internet stops working.

In the APN type field, you need to write default,supl. Make sure the protocol costs IPv4/IPv6 if your operator supports dual stack, which often helps improve server response.

Once you save a new access point, make sure to select it by putting a marker, and restart the phone. Using new parameters often gives you a tangible increase in connection stability.

Optimizing Wi-Fi Connection on Redmi 8

Smartphone Xiaomi Redmi 8 supports work in the bands 2.4 GHz and 5 GHz. However, by default, the device can cling to a more “long-range”, but slow range of 2.4 GHz, even if there is a fast network of 5 GHz.

Go to the advanced Wi-Fi settings. Find Use Wi-Fi or Wi-Fi Assistant. Here you can adjust the behavior of your phone when switching between networks. Turn off the Wi-Fi Assistant feature if it causes the phone to constantly scan the networks, consuming resources.

• 📡 Use the 5GHz band for streaming and gaming if the router is in the same room.
• 🔒 Choose a static one. IP-address in Wi-Fi network settings to avoid addressing conflicts.
• 🚫 Turn off the "accidental" MAC-address for a home network if the router is old and is not working properly with this function.

It is also worth paying attention to DNS-In the Wi-Fi settings, under "Settings" IP", Choose "Manual." In the fields. DNS 1 and DNS 2 Write down fast server addresses, such as those from Google (8.8.8.8) or Cloudflare (1.1.1.1.

Managing Background Processes and Traffic Limits

MIUI is known for its aggressive work with background processes, but sometimes parasitic applications can consume the entire channel unnoticed. Check data usage statistics to identify "infringers."

Go to Settings → Connection and Sharing → Data Transfer → Statistics. Sort the list by traffic spent. If you see an application that doesn't have to download updates or sync photos in the background, limit it.

⚠️ Note: Do not disable Google Play system services or system framework, this may disrupt notifications and_push_ service.

For each heavy application, you can set a limit. Click on the program name and select Background Connection → No restrictions (if you need to make it work) or disable background activity. This will free up the channel for your current tasks.

In addition, in the Traffic Saving section, you can activate a mode that blocks data transfer in the background for all applications except those you choose, which dramatically increases the response rate of the active application.

Using Hidden Engineering Menus and Network Reset

Android has a hidden test menu that is accessed through a set of special codes. Redmi 8 is currently code ##4636##. Enter it in the call and the "Verify" menu will open.

Select Phone Information. Find "Configure preferred network type." Make sure you choose LTE/TD-SCDMA/GSM (auto connect) or a similar 4G option. Sometimes you have 3G/2G mode, which greatly reduces speed.

Codeset: ##4636##


Way: Phone Information -> Preferred Network Type




Selection: LTE preferred

If nothing works, do a full network reset. This won't delete your photos or contacts, but it will reset your Wi-Fi passwords and Bluetooth settings. Way: Settings → Connection and Sharing → Reset Wi-Fi, cellular networks and Bluetooth.

💡

After resetting the networks, re-enter the Wi-Fi password and re-allow access to the geo-location for instant messengers, if necessary.

The Impact of DNS Cache and Browser Settings

Even with a perfect connection, slow DNS It can create the illusion of a bad Internet. A smartphone is wasting time searching. IP-- The site's address. DNS-Cache helps to solve this problem.

Modern versions of Android (and Redmi 8 is running on the current base) have a "Private DNS" feature. Find it in the settings search or in the Connection and Sharing → Private DNS section. Select "Host Name of the provider" and type in dns.google or 1dot1dot1dot1.cloudflare-dns.com.

• 🚀 Private DNS Encrypts requests and often runs faster than a standard ISP.
• 🧹 Clean your browser cache regularly, especially if you haven’t deleted your history in a long time.
• 📉 Turn off Page Preload in your browser if you have a restricted traffic tariff.

This setting applies globally to all applications that use a system solver. Changing DNS to a private server often solves the problem of long page loading starts.

💡

Integrated approach: The combination of proper APN, clean DNS and background application control gives the maximum result.

When to Consider Replacing Equipment

Sometimes software methods run out of potential. If your router was released more than 7-8 years ago, it may not physically support the modern encryption and speed standards that Redmi 8 requires.

If it is very old and cut manually from the Mini or Micro format to Nano, the contact can be unstable, which leads to a drop in speed to EDGE/3G. Replace the SIM card in the operator’s cabin with a new one with 4G/LTE support.

To sum up, Xiaomi Redmi 8 has the potential to be a comfortable surfing experience, and the network settings can unlock this potential. Remember to check system updates regularly, as Xiaomi engineers are constantly improving the modem in new firmware versions.
