How to turn on the maximum Internet speed on Xiaomi Redmi Note 7

Xiaomi Redmi Note 7 has been a popular device for several years, but over time, users may notice a decrease in mobile Internet speed, often due not to hardware limitations, but to software settings, accumulated cache or changes in the operator’s network parameters.

Many owners do not even suspect that the Android system and the shell MIUI And these are hidden tools that control network protocols, and if you configure them correctly, you can make the most of the coverage. 4G/LTE. In this article, we will discuss proven methods that will help stabilize the signal and increase the speed of data downloading.

Before we get to the tricky part, we need to rule out the trivial reasons for low speeds. Often the problem lies in the banal overload of background processes or incorrectly chosen network type. The key to success is a comprehensive approach: from checking the SIM card to setting up a setup. DNS-Let's look at each step in detail.

Diagnostics of the current state of the network

The first step is always to make an objective assessment of the situation, not just relying on the subjective feeling of the slow Internet, but using specialized tools to measure incoming and outgoing traffic, which will allow you to understand the real picture and track the effectiveness of subsequent settings.

Apps like Speedtest by Ookla or Fast.com are ideal for testing. Run the test in different locations to see if the problem is local (at home, in the office) or global. If ping scores are high and download speeds are low, you need to tamper with settings.

If you see a display at the top of the screen, if you're showing 3G or H+ instead of 4G or LTE, then the phone can't hold the fourth generation signal, and then the software settings may not help, and you'll need to find the best coverage or check the health of the SIM card.

It is also important to check if traffic saving mode is enabled, which artificially limits the background activity of applications. Go to settings and make sure that traffic limits are not set to minimum values. background restriction can block timely receipt of notifications and updates.

Basic setting of the APN access point

An access point (APN) is the gateway through which your device connects to the carrier’s Internet. Often the standard settings that come with a SIM card are not optimal for modern high-speed networks. Manual adjustment of APN settings can significantly reduce ping and speed up page loading.

To enter the settings menu, go on the Settings path → SIM-maps and mobile networks → Choose yours. SIM → Access points (APN). Here you will see a list of available profiles. Click on the button "New access point" or "Create" APN», to start editing parameters manually.

You have to enter the data that corresponds to your operator in the menu that opens, and usually just change the name and access point, for example, for many operators in the APN type field, you have to write default,supl,dun, which will ensure that high-speed data protocols are used as a priority.

After making changes, be sure to save the new profile and activate it by ticking the box. Reboot the device to make the changes effective. If the Internet does not appear after the reboot, check the correctness of the entered data on the official website of your carrier.

Use of alternatives DNS-server

Standard. DNS-servers provided by the provider by default are often overloaded or slow to process requests. DNS faster and more reliable servers, such as Google DNS Cloudflare, or Cloudflare, is a way to speed up network response when you open a site, and this is especially true when you're working with heavy resources.

Modern versions of MIUI and Android have a built-in Private DNS feature, which can be found in Settings → Connection and Sharing → Private DNS. Select the option “Host Name of the DNS Provider” and enter the address dns.google or 1dot1dot1dot1.cloudflare-dns.com.

This setting encrypts. DNS-requests, which not only speeds up their processing, but also increases the security of the connection, protecting against interception by the provider. DNS Prevents the substitution of site addresses and blocking access to certain resources.

⚠️ Note: Introducing an incorrect address DNS-If the network is lost after changing the settings, return the value to Auto or Off mode».

An alternative way – using the application DNS Changer or analogues that don't require root rights. They create local rights. VPN-This method is also effective, but can slightly increase battery consumption due to constant operation. VPN-protocol.

Secrets of the engineering menu and network modes

For advanced users, there is a hidden engineering menu where you can force the modem to switch modem mode, which allows you to lock the smartphone in LTE Only mode, preventing falls in 3G in areas of uncertain reception, where the phone is constantly looking for a better network.

You can log in to the engineering menu via the code set ##4636## in the Phone app. If the code doesn't work, you may need to install a special activator app from the app store. From the menu that opens, select Phone Information.

Find the option “Configure preferred network type” and select the option LTE Only or LTE/TD-SCDMA/CDMA/EvDo/GSM/WCDMA. The first option will only work in 4G, but in areas without LTE coverage, communication can completely disappear, including incoming calls.

Using LTE Only is especially important for smartphone-based routers or when using the device as a modem for a laptop, where channel stability is important, not the presence of voice communication.

System optimization and resetting network settings

Temporary files and network services can slow down the Internet. Periodic resets return all settings to factory values, removing conflicting configurations, a secure operation that does not affect personal files, photos or contacts.

You can reset via the Settings path → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Confirm the action, then the device will restart. You will have to re-enter the passwords from the Wi-Fi networks and reconfigure the Bluetooth headsets.

It’s also worth checking the system update list. Xiaomi regularly releases security and optimization patches for modems as part of MIUI updates. An outdated firmware version may contain bugs that affect the connection speed to base stations.

Note the table above: changing the APN protocol to a combined IPv4/IPv6 often allows a device to choose a faster traffic route if the carrier supports this standard, which is especially important for accessing modern Google resources and services.

External factors and physical level

Remember that software settings are powerless against physical constraints: a thick case with metal inserts, magnetic holders in the car or just a discharged battery can significantly impair the reception of the signal with the Redmi Note 7 antenna.

The state of the SIM card itself is also important, and if you use a SIM card that was released more than 5-7 years ago, it may not support modern encryption standards and 4G+ speeds, in which case replacing the SIM card in the carrier’s cabin with a new one (USIM) will solve the problem.

💡

Periodically wipe the SIM card contacts with a soft eraser. Contact oxidation is a common cause of unstable connections and periodic network breaks.

Check if the smartphone is overheating. When the processor and modem are heated, the system automatically reduces the performance and signal power to protect the components. If the phone is hot, let it cool down and check the speed again.

⚠️ Attention: Using third-party “Internet Accelerator” apps that promise a miracle 10x speed increase often backfires, creating a constant background load and displaying ads while consuming traffic.

In conclusion, for the best result on the Xiaomi Redmi Note 7, a combination of methods is recommended: configuring the correct APN, using fast DNS and resetting network settings in a timely manner.

💡

The maximum speed is achieved not by one “magic” switch, but by a combination of correct APN settings, current firmware and high-quality base station signal.
