Xiaomi Redmi Note 7 has been a popular device for several years, but over time users can face a noticeable drop in connection speeds. This is often due not to equipment wear, but to the accumulation of software errors or incorrect network settings. Modern applications require a stable data flow, and even minor delays can turn using the gadget into a test.
There are many ways to optimize communication modules without having to flash or call a service center. In this article, we will discuss proven methods that will help you regain maximum network performance. DNS-servers and use hidden engineering menus of the Android system.
Before you start complex manipulations, you should rule out the trivial reasons for slow work: check the balance of the operator, make sure that there is no technical work on the provider side, and assess the signal level in your location. If external factors are all right, then the problem lies in the software part of your Redmi Note 7.
Basic diagnostics and reboot of network modules
The easiest and often overlooked way to address speed issues is to completely reboot network settings. The MIUI operating system on the Redmi Note 7 accumulates temporary files and cache of network services that can cause conflicts over time, and simply turning off the screen does not clear that data, requires deeper intervention.
You need to reset your network settings, which will bring your Wi-Fi, Bluetooth and mobile internet settings back to factory values, and this will not delete your personal files, contacts or photos, but will forget your stored passwords from Wi-Fi networks. After the procedure, the phone will work with the network "cleanly", without the old configuration errors.
☑️ Actions before network reset
To perform the reset, go to the settings menu, select About Phone and find the reset point. In some versions of the firmware, the path may be different: Settings → Advanced Settings → Recovery and Reset → Reset Wi-Fi, mobile Internet and Bluetooth. Confirm the action and wait for the device to restart.
⚠️ Note: After resetting your network settings, you will need to re-enter passwords from all Wi-Fi routers you have previously connected to. Make sure you remember this data or it is stored in a cloud account.
Optimization of Access Point Settings (APN)
A key element of the mobile Internet is the access point settings, or APN (Access Point Name), and operators periodically update their gateways, and automatic settings that once came to SMS may no longer be relevant or contain errors.
To change the settings, open the settings of SIM cards and mobile networks. Find the "APN" and create a new record. It is important to enter the name and address of the server correctly. For most operators in Russia and the CIS, standard settings are relevant, but sometimes changing the protocol from IPv4 to IPv6 or adding DNS helps.
| Parameter | Value for adjustment | Description |
|---|---|---|
| Name. | FastInternet | Arbitrary name of new point |
| APN | internet | Main address of operator's gateway |
| Type APN | default,supl | Types of protocols supported |
| Protocol | IPv4/IPv6 | Recommended dual protocol |
Once you have entered, be sure to save the profile and activate it by ticking the appropriate box. Put your smartphone in flight mode for 10 seconds and return it to reconnect with the new settings. If the speed has not changed, try removing old, unused access points from the list.
💡
If the Internet stopped working after changing the APN, go back to the access point menu, click the menu (three dots) and select Reset to Standard. The system will download the current settings of your operator.
Use of fast-tracking DNS-server
The speed of opening sites depends not only on the communication channel, but also on the response time. DNS-Providers often use their standard servers, which can be overloaded or slow to process requests, replacing them with public and fast servers. DNS Google or Cloudflare are an effective way to speed up the response of the Redmi Note 7.
In modern versions of Android (starting with version 9) and shell MIUI There is a built-in function "Private" DNS». It allows you to encrypt. DNS-requests and forward them to the selected server without installing additional applications. This works for both mobile Internet and Wi-Fi connections.
Go to Connect and Share or search for DNS settings. Select DNS Host Name and enter the address of one of the fastest servers. Cloudflare (1.1.1.1) and Google (8.8.8.8) servers are considered the most stable, which provide minimal latency.
List of fast DNS servers
After you set the settings, check the speed through a specialized test, and you may notice that pages start loading instantly, even if the overall channel speed remains the same, by reducing the time you spend searching for a site address.
Wi-Fi settings: frequencies and ranges
When using a wireless network on Xiaomi Redmi Note 7, it is critical to choose the right frequency range. The device supports 2.4 GHz and 5 GHz networks. The 2.4 GHz range is more long-range, but is heavily noisy with neighboring routers and household appliances, which leads to a drop in speed.
If your router supports 5GHz, make sure to switch your smartphone to this network, which provides higher bandwidth and is less prone to interference, but its range is shorter, so to speed up the Internet, move closer to the signal source.
You also need to look at the settings of the router itself, and sometimes it helps to change the channel in the settings of the router to a less loaded one. In the menu of the smartphone in the Wi-Fi section, you can see the speed rating: if it is low with a good signal, the problem is most likely interference or a channel.
⚠️ Note: Not all routers support 5 GHz. If you don't see a name with a prefix in the list of available networks «5G» or a separate name, which means your router is only running at 2.4 GHz.
Hidden settings and engineering menu
For advanced users, the Redmi Note 7 provides access to an engineering menu where you can force the network mode to switch. Often the phone is stuck in 3G or H+ mode, even when there is 4G/LTE coverage. Forced installation of the preferred type of network can solve the problem.
To enter the test menu, open the Phone app and dial the combination ##4636##. The hidden menu will open before you. Select Phone Information. Here, find the drop-down list "Set up your preferred network type."
Recommended choice: LTE Only (LTE only)
Or: LTE/TD-SCDMA/WCDMA (Auto)Choosing LTE Only mode will make the communication module ignore 2G and 3G towers, which will speed up switching between base stations and stabilize ping in games. However, remember that in areas with poor 4G coverage, communication can completely disappear, since the phone will not be able to switch to 3G.
💡
Using LTE Only mode on the engineering menu is a radical but effective way to make the phone hold onto fast 4G internet while ignoring the slow networks of previous generations.
To return to standard system behavior, select LTE/WCDMA/GSM (auto connect) mode, which will allow automatic switching between communication standards based on signal quality.
Removal of system debris and background processes
Internet speed is indirectly affected by CPU and RAM loads, and if there are many heavy applications running in the background, they can consume traffic and create queues, and Xiaomi is particularly aggressive in its background processes and advertising in system applications.
It is recommended to regularly clean the browser and system services cache. Go to Settings → Apps → All Apps. Find browsers (Chrome, Mi Browser) and click Clear → Clear cache. Also check the list of running processes and close the unnecessary ones.
Turn off the Mi Assistant or Memory Cleanup function in the background if they are constantly hanging in memory, consuming resources. Also, disabling app auto-update via mobile network in Google Play will save your traffic and speed up active tasks.
