Slow loading of pages, interruption of video stream and endless waiting for a response from the server are a familiar picture for many owners of Xiaomi, Redmi and Poco smartphones. The problem of unstable connection can be hidden not only in a weak signal of the operator, but also in software failures or incorrect settings of the MIUI operating system (now HyperOS).
In this article, we’ll look at the best practices to help you boost your web experience on Xiaomi without buying any additional hardware. We’ll look at both standard and advanced customization options available to every device owner.
Before we go to radical measures like resetting, we should try to optimize the current state of the system. Cache data, background processes, and specific access point settings can significantly affect data rate. Let's start with a basic, but most effective, action.
Basic diagnostics and reboot of the communication module
The first step should always be to check the physical state of the signal simulation. Often the communication module simply "hangs" or accumulates errors when switching between cell towers. 10-15 It causes the radio to shut down completely and then re-enter the operator's network. IP-Select the nearest base station and address.
If a simple restart doesn't work, you need to check your mobile network settings. Make sure that the Settings menu is on the Settings menu. → SIM-maps and mobile networks → Preferred network type selected mode 4G (LTE) or 5G, If your tariff and coverage allow, sometimes the phone switches to the phone itself. 3G or 2G energy saving, which reduces speed critically.
It is also important to pay attention to the physical location. SIM-If you haven't touched the tray in a while, the contacts may have oxidized or become contaminated. Take out the card, wipe the contacts with soft cloth, and make sure that it sits tightly in the slot. For dual-sim devices, it is important to check which SIM card is assigned to transfer data, since the second one can be configured to the mode. 2G.
⚠️ Attention: Before extraction SIM-Make sure your phone is turned off or use the Hot Replace feature if supported by your model to avoid damage to contacts or software glitches.
There's another thing about VoLTE, and if your carrier supports this technology, turning it on can improve voice quality, but in rare cases, on older towers, it causes Internet speed to drop. SIM-maps and check the results.
Shift. DNS-servers to speed up response
One of the most effective ways to speed up the loading of web pages is to change the DNS-Servers. Providers often use overloaded servers by default, which increases response times. DNS Google or Cloudflare can significantly strengthen the Internet, making navigation more responsive.
To perform this procedure on modern versions of Android and shells MIUI/HyperOS You don't need root rights. You need to go to Settings. → Connection and sharing → Private DNS. Here you can manually write down the address of a reliable server.
- 🚀 dns.google is a reliable server from Google, providing a stable connection.
- ⚡ 1dot1dot1dot1.cloudflare-dns.com — one of the fastest DNS worldly.
- 🛡️ dns.adguard.com – Blocks Advertising at the Level DNS, speeding up page loading.
Once you enter the address, you need to click Save and restart the device. The changes will take effect immediately. It is worth noting that using third-party DNS can help bypass some ISP locks, but will not increase the physical speed of the channel if it is limited by the tariff.
💡
Before changing the DNS, write down the current settings or take a screenshot so that in case of problems, you can return everything as it was by selecting the “Auto” or “Switched off” mode.
If the speed hasn't changed since the DNS change, try switching between different options. Sometimes the server that's physically farther away is faster because of the lower load. Experiment to find the optimal solution for your region.
Resetting Access Point Settings (APN)
APN settings are a key parameter that determines how your phone connects to the carrier’s Internet, and errors in that data, or their obsolescence after a tariff change, can lead to a critical drop in speed, and resetting those settings to factory values often solves the problem.
To perform the reset, go to the Settings menu → SIM-maps and mobile networks → Choose yours. SIM-map → Access points (APN). In the list that opens, click on the menu (three dots or the “More” button) and select “Reset to default settings.” The phone will automatically download the current settings from the operator.
| Parameter | Description | Impact on speed |
|---|---|---|
| Name | Profile name (e.g. MTS Internet) | Low (for identification only) |
| APN | Access point (for example, Internet.mts.ru) | Critical (without the correct value there is no network) |
| Proxy | Address of the proxy server | High (incorrect proxy blocks traffic) |
| Port | Portal of connection | Average (must match the operator's requirements) |
In some cases, manual adjustments like APN can help. Go to the Active AP edit, find the APN Type field and make sure it says default, supl, or just default. If it says you have extra options, delete them. Also, in the APN Protocol field, you should choose IPv4/IPv6 for maximum compatibility.
☑️ Checking settings APN
After settings, be sure to turn on and off mobile data transmission. If the Internet does not work, check whether the access point itself is activated (whether the checkmark or circle next to the profile is located). Without an active access point, the connection will not be established.
Optimizing Wi-Fi Connection
If the problem is observed when connecting to the home network, it is worth checking the Wi-Fi settings on the Xiaomi smartphone itself. MIUI shell has features that can interfere with stability. First of all, turn off the Wi-Fi Assistant or Wi-Fi Acceleration, which try to switch to mobile Internet at a weak signal, causing breaks.
It is also important to pay attention to the Wi-Fi frequency. If your router is dual-band, try to connect to a 5 GHz network rather than 2.4 GHz. 5 GHz provides a much higher data rate, although it has a shorter range. For stationary use in one room, this is ideal.
Network resets are a more radical but powerful method, which will delete all stored Wi-Fi passwords and Bluetooth settings, but return the network stack to its original state. You can find this option by Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.
⚠️ Warning: Resetting network settings will remove all saved passwords from Wi-Fi networks.Make sure you remember the password from your home router before performing this operation.
Hidden commands for diagnosis
And don't forget the router's position. Metal structures, mirrors, and microwaves are jamming, and moving the router to an open location or lifting it up higher can give you a speed boost comparable to replacing the hardware.
Using an engineering menu to select ranges
For advanced users, it is possible to force the modem to run on bandwidths, especially in areas where the phone is constantly jumping between 3G and 4G, losing signal, and the engineering menu allows you to lock in the preferred standard.
Open the Phone app and dial ##4636##. From the menu that opens, select Phone Information. Find "Configure preferred network type «LTE only” (Only LTE), so that the phone doesn't go into 3G, even if 4G will become weak.
- 📶 LTE Only - forced labor only in the 4G, precludes falling 3G/2G.
- 📡 GSM Only - useful in remote villages where only Edge is caught.
- 🔄 NR/LTE/GSM — priority-free 5G (if maintained).
Using LTE Only mode can cause incoming calls to stop going through if the carrier does not have VoLTE technology configured, so use this method with caution and only if you are confident in supporting 4G voice calls in your area.
The alternative is to use network mode switching applications that create a desktop widget, which allows you to quickly change 4G/3G/2G modes with a single touch without logging into the deep settings menu, which is convenient when traveling.
💡
Forced 4G fixation (LTE) helps avoid constant reconnections in unstable reception areas, but can disable the ability to receive regular voice calls without VoLTE.
Impact of Updates and Reset to Factory Settings
Sometimes the cause of bad Internet are software bugs in the current version of firmware. Xiaomi regularly releases security and system optimization updates, which may contain patches for communication modules. → The phone. → Version. MIUI/HyperOS.
If the problem has occurred after a recent update, there may be errors in the new version, in which case it is worth waiting for the next patch or, if the situation is critical, roll back to the previous version through the service center, however, it is often the update to the latest stable version that helps.
If none of these methods worked, the last resort is a complete data reset, which will remove all apps, photos and contacts, returning the phone to the “out of the box” state.
⚠️ Warning: Full Hard Reset permanently deletes all user data. Make sure you have an up-to-date backup before you begin the cleanup process.
After reset, don't restore all applications from backup. First, check the Internet on a clean system. If the speed is high, then one of the applications installed earlier, which was in conflict with network services, created the problem.
