1. Preparing your phone for Wi-Fi connection

Before you begin setting up, make sure that your Redmi Ready for wireless networks. Even new phones sometimes require some preparation—especially if you purchased a device with firmware for a different region.

First of all, check MIUI version in the section Settings → About phone. Outdated versions may not support modern security protocols (e.g. WPA3), which will lead to connection issues with new routers. If the firmware version is older than 2023, we recommend updating via Settings → System Update.

It is also worth making sure that on the phone the Wi-Fi module is enabledSometimes users accidentally disable it through the Quick Settings panel or airplane mode. You can check this by swiping down from the top of the screen—the Wi-Fi icon should be lit in the drop-down menu.

• 📜 Network name (SSID) — it’s usually written on the router’s sticker
• 🔑 Password — case sensitive, check your keyboard layout
• 📡 Security type (WPA2, WPA3) - if you don't know, check your router settings

⚠️ Attention: If your Redmi I connected to this network before but now I can't connect, try delete saved network in the Wi-Fi settings. Old authorization data may conflict with the new router settings.

4. Select your network from the list. If it's not there:
   • 🔍 Make sure your router is turned on and broadcasting its SSID (sometimes hidden)
   • 📶 Check if you are too far from the router (especially relevant for 5 GHz)

Enter your password and click ConnectIf a security warning appears, confirm the connection.

If the connection is successful, a checkmark will appear next to the network name and a Wi-Fi icon will appear in the status bar. You can use the app to check your connection speed. Speedtest or built-in test in Settings → Wi-Fi → [network name] → Speed.

Even after proper configuration, users Redmi Sometimes we encounter connection errors. Let's look at the most common issues and how to fix them.

"Connecting... Saved, but no internet access" — one of the most common mistakes. The reasons can be various:

• 🔌 Problems on the provider's side (check if the internet works on other devices)
• ⚙️ Incorrect IP settings (try switching between DHCP and static IP)
• 🔒 MAC address blocking (check your router settings)

To fix this error:

1. Forget the network in Wi-Fi settings.
2. Reboot your router (turn it off for 30 seconds).
3. Try connecting again by selecting manually Obtain an IP automatically.

"Wi-Fi is connected, but pages won't load." — often related to DNS settings. Try manually specifying Google's DNS servers (8.8.8.8 And 8.8.4.4) in the network settings.

⚠️ Attention: If the problem occurs only on Redmi, and other devices are working fine, check the settings VPN And Saving traffic in MIUI. Sometimes these features block internet access.

If your Redmi If your phone connects to the network, but the speed leaves much to be desired, try the following optimization methods. Let's start with the phone's settings.

MIUI has a built-in Wi-Fi performance mode, which can be included in Settings → Accessibility → Performance modeThis option disables background app activity when you're using Wi-Fi to download large files or stream.

For deeper customization:

• 📉 Limit background traffic for unnecessary applications in Settings → Applications → Data Management
• 🔄 Turn off auto-update applications in Google Play via mobile data
• 📡 Use a fixed channel on the router instead of automatic selection (especially relevant for densely populated areas)

If you use Redmi For games or video calls, turn on the mode Game Turbo (available in the notification shade or via Settings → Accessibility). This feature prioritizes network traffic for games and reduces latency.

Don't forget about physical factors: thick walls, microwaves, and even aquariums can degrade the signal. If possible, place the router closer to where the phone is used or use signal repeaters.

6. Security: How to protect your connection

Public Wi-Fi networks (in cafes, hotels, airports) are convenient, but often unsafe. Attackers can intercept traffic or create fake access points. On phones Redmi There are several functions for protection.

First rule: Never connect to open networks without encryption.If the network doesn't require a password, there's a high risk that your data (including logins and passwords) could be intercepted. You can enable this option in MIUI. Warn about unsafe networks in the Wi-Fi settings.

For additional protection:

• 🔐 Use VPN (for example, built into MIUI Mi VPN or third-party solutions like ProtonVPN)
• 🛡️ Turn on MIUI Firewall V Settings → Security
• 🔄 Update your firmware regularly – new versions of MIUI fix vulnerabilities

If you frequently connect to corporate networks, pay attention to the settings Safety certificates V Settings → Security → AdvancedHere you can install root certificates for secure networks (for example, EAP-SIM or PEAP).

⚠️ Warning: Avoid using functions like Wi-Fi Direct or Mi Share in public places. These technologies create direct connections between devices, which can be exploited for attacks.

For maximum home security, configure the router guest network with a separate password. Connect guest devices to it, and keep the main network for your own devices only.

7. Specific settings for different Redmi models

While most Wi-Fi features are universal across all Redmi, some models have unique features. For example, flagship devices (Redmi Note 13 Pro+, Redmi K60) support Wi-Fi 6 And 160 MHz channels, which requires appropriate router configuration.

For budget models (Redmi 10A, Redmi 12C) the following restrictions apply:

• 📶 No support 5 GHz (only 2.4 GHz)
• 🔌 Limited maximum speed (up to 150 Mbps)
• 🔄 No support MU-MIMO and other modern technologies

If you have one of the latest models (Redmi Note 13 or newer), check for the presence of the function Wi-Fi AssistIt automatically switches between Wi-Fi and mobile data to ensure a stable connection. It turns on in Settings → Connections → Wi-Fi Assist.
