How to install the Internet on Xiaomi Redmi 9: full instructions

A modern smartphone is impossible to imagine without access to the global network, and Xiaomi Redmi 9 is no exception. After buying a device or resetting to the factory settings, the first critical step is to connect to Wi-Fi or adjust mobile traffic. Often users are faced with a situation where the phone sees the router but does not connect to it, or the SIM card is active, but the web pages do not open.

In this detailed guide, we will take a look at the network configurations for your model, how to enter provider data correctly, change DNS to speed up downloads, and what to do if standard methods do not help restore a stable connection.

We will look at both automatic and manual configurations, focusing on APN hotspot parameters, which often cause Internet outages when using a mobile operator, and also address security and speed optimization.

Preparation for setup and inspection of equipment

Before you start the software manipulations in the menu MIUI, You need to make sure that the components are physically healthy, and often the problem is not a software failure, but a simple lack of signal or improper installation. SIM-Make sure your plan is active and funds are available in your account, as without this, the operator blocks the transfer of data.

If you plan to use Wi-Fi, check the router's performance on other devices.In the case of mobile internet, it's important that the SIM card is installed in the correct slot, especially if you're using two devices. SIM-In some configurations, slots may have support limitations. 4G/LTE.

Notice the indicators at the top of the screen, if you see a 4G or 5G icon, but the pages are not loading, the problem is the access point settings, and if the icon is not at all, it may not be on or the map is not defined by the system.

Set up mobile Internet through the operator

In most cases, Xiaomi Redmi 9 automatically detects the carrier and loads the necessary parameters to access the network. However, if this does not happen, you will need to create a profile of the access point (APN) To start, go to the Settings menu, then select the item. SIM-maps and mobile networks.

In the window that opens, look for the Access Points (APN) section, which may be empty or already have a profile list. If the list is empty or the current profile is not working, click the + or New Access Point button at the bottom of the screen and you will need to enter the data that your mobile operator provides.

Key fields to fill in are Name (anything, such as MTS Internet) and APN (access point address, such as internet.mts.com). The remaining fields, such as username and password, are often left blank or filled in according to the operator's specification.

• 📱 Name: arbitrary profile name for your convenience.
• 🌐 APN: technical address of the operator's gateway (required).
• 🔑 Password/login: only if required by your provider.
• 💾 Save: Be sure to click Save and activate the point.

After entering all the data, remember to save the profile and switch the tick to it. Rebooting the device after this procedure will help to fix the changes and start the connection again.

Manual configuration of APN parameters

If the automatic setup doesn't work, manual configuration is the only way out. It's important to understand that for different operators (MTS, Beeline, Megafon, Tele2), the parameters are different. Error even in one character in the APN field will lead to the fact that the Internet will not work.

Extended access point settings sometimes require you to specify the protocol type. Modern networks recommend choosing IPv4/IPv6. It is also worth checking the Authentication Type field - usually installed in PAP or CHAP, but can often remain empty.

💡

Use the APN option to copy from another phone if it is available in the access point menu, which will eliminate manual input errors and save time.

Once you have created a new access point, be sure to go back a step and make sure that the marker is on the profile you created.The system can by default leave the old, non-working profile active.

Connecting to Wi-Fi Networks and Solving Problems

Connecting to the wireless network on Xiaomi Redmi 9 is via the Settings → Wi-Fi menu. Turn on the activation slider and select your network from the list of available ones.

Users often encounter a problem when the phone writes “Receiving” IP-"and then gives an error, which may indicate a conflict." IP-addresses or problems with DHCP-router server, then change the settings IP statically.

To adjust the static IP Click on the arrow next to your network name or select "More." Change the settings. IP s DHCP You'll need to manually prescribe it. IP-address (e.g. 192.168.1.150), gateway (router address, usually 192.168.1.1) and DNS.

• 🔢 IP-Address: Unique phone address on the local network.
• 🚪 Gateway: address of your router (router).
• 📡 DNS 1: primary domain name server (can be specified 8.8.8.8).
• 🔒 Security: Type of encryption (usually) WPA2/WPA3).

Use of public use DNS-Servers from Google (8.8.8.8) or Cloudflare (1.1.1.1) often help speed up network response and bypass ISP locks if they apply.

Using DNS to Accelerate and Safety

The Android operating system that runs MIUI has an encrypted DNS feature that protects your requests from the provider and speeds up site opening. To activate, go to Settings → Connection and Sharing → Private DNS (or DNS).

By default, you have the "Auto" value. Switch the mode to the Host Name of the private DNS provider. In the field that appears, enter the service address. A popular and reliable option is the service from Google: dns.google or from AdGuard for blocking ads: dns.adguard.com.

This setting works globally for all applications and browsers on your Redmi 9.It is especially useful when using public Wi-Fi networks in shopping malls or airports where data security is at risk.

Resetting network settings and diagnostics

Once you reboot, you'll have to re-enter the Wi-Fi passwords and maybe reconfigure the APN access points if they don't automatically load, but this often solves the software bugs of the network module.

In rare cases, the problem may lie in mechanical damage to the antenna or the communication module itself, especially if the phone fell or was exposed to moisture.

💡

Network reset is a safe and effective procedure that eliminates 90% of software connection errors without deleting the user’s personal data.
