How to improve mobile Internet on Xiaomi Redmi Note 7

The Redmi Note 7 remains a popular device due to its excellent price-performance balance, but over time users may experience a drop in mobile internet speeds, especially in areas of uncertain reception where the device loses signal or switches to slower communication standards. Slow internet is often the result of accumulated system errors or incorrect operator settings, rather than hardware breakdowns.

Before you look for complex solutions, you should check the basic parameters. SIM-The card is activated by the preferred network type set to 4G (LTE). Sometimes the system switches the phone to the 3G to save charge, which critically reduces the speed of page loading and streaming video.

In this article, we will discuss proven methods that will help resuscitate a connection, how to properly configure APN access points, whether to use an engineering menu to force frequency selection, and what system commands can clear network caches, which are safe if you follow the instructions.

Basic diagnostics and resetting of network settings

The first step should always be basic diagnostics. Often the problem lies not in the phone, but in the “hung” communication module, which stops correctly processing incoming data packets from the operator, and a simple reboot may not be enough if the system has accumulated temporary files that conflict with the current network profile.

The most effective "level one" method is to completely reset your network settings, which won't delete your personal photos or contacts, but will bring all your Wi-Fi, Bluetooth and mobile Internet settings back to factory values, which is especially useful after you update your MIUI firmware.

To do this, go to Settings → Advanced Settings → Restore and Reset. Find “Reset Wi-Fi, Mobile Internet and Bluetooth settings” and confirm the action. After the reboot, you will need to re-enter wireless passwords.

⚠️ Note: After resetting the network settings, all saved passwords from Wi-Fi routers and a pair of Bluetooth devices will be deleted. Write down or take photos of complex passwords in advance so you don’t waste time restoring them.

If the situation has not changed after the reset, the problem may be physical. SIM-Older Mini-SIM cards, cropped as nano, may not make good contact with pins in the tray, and contact oxidation can cause periodic breaks in the connection.

Manually configuring APN access points

Automatic settings that come from the operator in the form of SMS, often contain outdated parameters or do not take into account the specifics of the operation of modern 4G networks. Manual editing of the access point (APN) can significantly improve the stability of ping and the response speed of the server.

To get into the settings menu, open Settings → SIM-Maps and mobile networks. Choose the right one. SIM-map, then go to "Access Points (APN)". Click the menu button (three dots or gear) and select "New Access Point" or "Reset to standard ones".

In the window that opens, you need to fill in the fields according to your operator's data. For most Russian operators (MTS, Beeline, MegaFon, Tele2), the username and password fields often remain empty, but the APN type field should contain the default,supl value.

  • 📱 Name: Enter any name, such as "FastNet".
  • 📡 Access point (APN): Enter the address indicated on your operator’s website (for example, Internet.mts.ru).
  • 🔒 Type of authentication: Select PAP or CHAP (experimentally).
  • ⚙️ Protocol APN: Set the value IPv4/IPv6.

Once saved, be sure to restart the device. A critical parameter is the APN Protocol: setting IPv4/IPv6 instead of pure IPv4 often solves problems with accessing some modern Google sites and services.

Done: 0 / 1

Don't be afraid to experiment with the type of protocol. If you have IPv6, try switching to IPv4. In some regions, providers still don't have full support for the new standard, causing delays in connection installation.

Using an engineering menu to select frequencies

Xiaomi Redmi Note 7 is based on the Snapdragon processor, which has a hidden engineering menu that allows you to force the phone to switch to certain LTE frequencies. This is useful if the operator's base station is overloaded on one frequency, but free on another.

To enter the menu, dial ##4636## in your phone. Select Phone Information. Find Set Preferred Network Type.

Here you will see a drop-down list with many options. The default is usually LTE/TD-SCDMA/CDMA/EVDO/GSM/WCDMA. Try selecting a mode that only says LTE Only or LTE/WCDMA. This will prevent the phone from switching to EDGE or 3G, even if the 4G signal becomes weak.

⚠️ Attention: Regime "LTE Only" can cause incoming calls to stop passing if your carrier does not support VoLTE technology. Use this mode only for Internet distribution or when calls are not important.

Also in this menu you can see the signal level in dBm. Normal value is considered from -80 to -95 dBm. If the value is below -110 dBm, the phone will constantly lose network, and no software settings will help - only a change of location or antenna will help.

What do the dBm numbers mean?
The signal in dBm is a negative number, and the closer it is to zero, the better the signal, -70 dBm is better than -100 dBm Values below -115 dBm is considered a dead zone where communication is virtually impossible.> Using the engineering menu is a powerful tool, but it requires caution.Do not change the settings that are not sure, as this can lead to the complete disappearance of the network before rebooting. MIUI It has a lot of background processes that can consume traffic and load the modem. Aggressive battery optimization sometimes kills the processes that are responsible for the stability of the connection, or vice versa, prevents the communication module from working at full capacity. → Battery and performance: Make sure the power saving mode is off or set to Classic mode". The "Economic" mode often restricts background data transfer, which causes notifications to arrive with a delay, and pages loaded with jerks. It is also worth clearing the cache of Google system services and framework services. → Annexes → All apps. Find "Google Play Services" and click "Clean Up" → "Clear the cache." This won't delete your data, but update the service information. 🚀 Turn off traffic savings: Check if the traffic limiter is turned on in the notification curtain. 📉 Reset DNS: Try to prescribe a static one. DNS (8.8.8.8.8 in Wi-Fi settings or via an application. 🔄 Base Station Update: Turn on and off Flight Mode for 10 seconds to reconnect to the nearest tower. If the time on the phone is knocked down, the site security certificates may not pass the check, and the browser will write "No Internet connection", although the network is formally there. 7 It has a glass back cover, which is good for the signal, but the antenna inserts are located at the ends. 10-15 dBm. Try to take off the case and check the speed in the same place. If the difference is significant, then the accessory is blocking the antenna. SIM-If it is deformed or contaminated, contact with the card will be unstable. The table below shows the main causes of signal drop and methods of their elimination: Problem Symptom Solution Contact Pollution Periodic disappearance of the network Wipe contacts SIM The old-fashioned stainless stainless stainless 4G, Frequent switching Updates MIUI up to the last version of the wrong APN Internet is, but sites are not loaded Create a new access point manually Overheat modem Reduce speed when loading Remove the case, let cool If after all the manipulations the Internet works poorly only in one particular room, perhaps it is the thickness of the walls or materials of the building. In this case, only Wi-Fi calling or a signal repeater will help. Resetting to factory settings as a last resort If software failures become critical and nothing helps, then the radical method remains - a complete reset (Hard Reset). This will put the phone back out of the box, removing all the setting conflicts that may have accumulated over the years of use.Be sure to back up your data to the Mi Cloud cloud or your computer before the procedure.Reset will destroy all photos, contacts and installed apps. Go to Settings. → The phone. → Resetting settings → Delete all data. Don't restore the backup of the applications immediately after reset. First, check the Internet on a clean system. If the speed is high, then one of the installed applications or their conflict created the problem. 💡A complete reset is a guaranteed way to fix network software errors, but it takes time to reconfigure the phone and install apps. In rare cases, the problem can be hardware - failure of the antenna module or plume. If, even after a reset and inspection from another SIM-No signal on the card, you'll need a diagnosis at the service center (FAQ) Why the Redmi Note 7 is on the lookout 4G, But the Internet doesn't work? Most often, it means an error in the settings of the access point. APN or lack of balance/traffic on the operator. APN And try to turn on/off flight mode. Is it safe to use code ##4636##? Yes, this is the standard Android engineering menu, LTE Only) may temporarily prevent you from receiving regular voice calls if VoLTE is not supported. Could installing a third-party launcher affect Internet speed? However, some accelerators or cliners from third-party applications may conflict with Xiaomi system services, disrupting the network. What if 4G is missing after the MIUI update? Network settings often fly out after the update. Reset the network settings (not a full phone reset) in the recovery menu. Also check if your preferred network type has reset to 3G/2G.
