How to set up DNS on Xiaomi Redmi 3S: 3 ways to speed up the Internet

Smartphone Xiaomi Redmi 3S It is still popular today because of its reliability and budget price, but over time, many users face slowing internet speeds, problems accessing some sites, or frequent connection errors. In 90% of cases, these problems are solved by correct settings. DNS-servers – special addresses that translate domain names (such as google.com) into IP-addresses that are understandable to the device.

In this article, we will explain why the standard DNS The provider may be slowing down your Redmi. 3S, Which alternative servers to choose for maximum speed and security, and also show 3 working ways of configuring them: through the parameters of Wi-Fi, mobile network and using third-party applications. MIUI on your device – they may affect the availability of certain features.

Why change DNS to Xiaomi Redmi 3S?

By default, your smartphone is using DNS-servers that are automatically assigned by the ISP, and it's not always optimal for several reasons:

• 🐢 Low loading speed: provider DNS Often overloaded, which increases the response time of sites.
• 🚫 Content blocking: Some servers restrict access to certain resources (e.g. Netflix or Telegram).
• 🛡️ Lack of protection: standard DNS They do not encrypt traffic, making it vulnerable to interception.
• 🌍 Geographical restrictions: 403 Forbidden error may be detected when connecting to foreign sites.

Tests show that replacing DNS with Redmi 3S can increase page load speeds by 30-50% (the data is relevant for MIUI 9-12 firmware), and it is the only legal way to get around blocking without using a VPN that does not require root rights.

⚠️ Note: If you use a corporate or learning network (such as an office or university), change DNS It may violate security rules, and in such cases, it is better to check the permission of the administrator.

What are they? DNS-Select servers for Redmi 3S?

The choice of DNS depends on your goals, and we have collected proven options with their features:

For most Redmi 3S users, Cloudflare (1.1.1.1) is the best choice, combining speed and privacy. If you want to protect against phishing, try OpenDNS. Google DNS is suitable for accessing resources blocked in Russia (for example, Twitter or Reddit).

Method 1: Configure DNS for Wi-Fi network

This is the simplest method, which does not require additional applications to be installed, and the instructions are relevant for MIUI 9-12 (on newer versions, the path may differ slightly).

4. Scroll down to IP Settings and select Static (instead of DHCP).
5. In the DNS 1 and DNS 2 fields, enter the selected addresses (e.g. 1.1.1.1 and 1.0.0.1 for Cloudflare).
6. Save the changes and reconnect to the network.

To check if the settings have been applied, open the browser and go to the site. DNS Leak Test. The results should show up. IP-address of your choice DNS-provider.

⚠️ Note: If after the change DNS Some sites (e.g., banking sites) have stopped opening, return the standard settings, some resources block access from non-fiction sites" DNS for security reasons.

Method 2: Changing DNS for Mobile Internet (3G/4G)

Setting up a DNS for a mobile network on Redmi 3S is a bit more complicated, because MIUI doesn't provide a direct interface for that, but there's a workaround through creating a new APN. This method works on all firmware versions, including MIUI 8.

Important: Before starting, write down the current parameters. APN (You can find them in the settings. → SIM-maps and mobile networks → Access points (APN)), To bring it back if necessary.

Instructions:

1. Go to Settings. → SIM-maps and mobile networks → Access point (APN).
2. Click on your current profile (usually referred to as your carrier, such as MTS or Beeline).
3. In the field APN-select protocol IPv4 (If there is no such item, skip the step).
4. Find the DNS 1 and DNS 2 fields (if none are available, click Add New APN and fill in all required fields by copying them from the standard profile).
5. Enter the selected DNS-addresses (e.g. 8.8.8.8 and 8.8.4.4 for Google).
6. Save the changes and restart the phone.

After you reboot, check your internet speed with Speedtest. If the speed drops, return the standard APN settings.

Method 3: Using Third-Party Applications

If the first two methods didn’t work or you need flexibility (e.g., switching between the two methods quickly). DNS), Install a specialized application. 3S fit:

• 📱 1.1.1.1: Faster & Safer Internet (from Cloudflare) – simple interface, automatic connection.
• 🔒 DNS Changer – Supports customization DNS, Shows ping to servers.
• 🌐 NextDNS – allows you to create your own filters for blocking ads and trackers.

Let’s look at the example of 1.1.1.1:

1. Download the app from Google Play.
2. When you first start, press Connect and allow creation. VPN-Connections (this is necessary for redirection) DNS-traffic).
3. In the settings, select 1.1.1.1 (for maximum speed) or 1.1.1.2 (for blocking malicious sites).
4. Activate the switch in the main window of the application.

The advantage of this method is that it can quickly disable DNS without changing system settings, and it also shows statistics of blocked requests and server response times.

💡

If banking applications (e.g. Sberbank or Tinkoff) have stopped working after installing DNS applications, add them to exceptions in the application settings or temporarily disable custom DNS. Banks often block access from “non-standard” networks for security reasons.

Problems and Solutions in Configuring DNS

• 📶 Signal strength: A weak Wi-Fi or mobile network signal can mask problems with the signal. DNS.
• 🛠️ Conflict with VPN: Shut it down. VPN-pre-setting DNS.

💡

• 🧹 Clear the network cache: in Settings → Annexes → Application management → Three dots (menu) → Resetting application settings.

For advanced users: If you have root access, you can edit /system/etc/resolv.conf manually, but it’s risky – making incorrect changes can lead to loss of the Internet.

Also, look for alternative firmware (like LineageOS), which offers more flexible network settings, but installing them requires unlocking the bootloader and may take away your warranty.
