How to Set Up Wi-Fi on Xiaomi Devices: From Smartphone to Router

Devices Xiaomi — from smartphones to smart lamps — require proper configuration Wi-Fi for stable operation. But even experienced users encounter problems: the network can't find the device, the speed drops significantly, or the router Mi Router refuses to save settings. In this article, we'll look into it. All methods of setting up Wi-Fi on different devices Xiaomi, including hidden functions MIUI 15 And HyperOS, as well as resolved errors.

Ecosystem feature Xiaomi - tight integration between devices. For example, a smartphone on MIUI can automatically connect to the router Mi Router 4A without entering a password if both devices are linked to the same account Mi AccountBut this same feature sometimes leads to conflicts, when, for example, the TV Mi TV"forgets" the network after an update. We'll tell you how to avoid such situations and configure Wi-Fi is optimal for your needs—whether it's gaming, 4K streaming, or smart home computing.

1. Setting up Wi-Fi on Xiaomi smartphones (MIUI 15 / HyperOS)

To open advanced settings, go to Settings → Wi-Fi, tap on your network name and select Change networkHere you can:

• 🔄 Enable auto-connection (useful for smart home)
• 📶 Set up network priority (5 GHz or 2.4 GHz)
• 🔒 Edit security type (WPA3 is not supported by all routers)
• 📊 Enable traffic statistics to monitor consumption

Please note the function Wi-Fi Direct (on the menu Additionally). It allows you to transfer files between devices. Xiaomi at a speed of up to 300 Mbps — faster than Bluetooth, but with a shorter range (up to 10 meters).

⚠️ Attention: If after updating to HyperOS If your smartphone no longer detects 5 GHz networks, check your regional settings. Some firmware versions block this frequency for countries where it's not officially supported. Solution: change the region to India or USA in the developer settings.

2. Connect to a hidden Wi-Fi network on Xiaomi

Hidden networks (with SSID broadcast disabled) are often used for increased security, but setting them up Xiaomi has its nuances. Unlike the iPhone, where you only need to enter the network name manually, on MIUI need to:

1. Go to Settings → Wi-Fi → Add network
2. In the field Network name (SSID) Enter the exact name (case sensitive!)
3. Select security type (WPA2/WPA3 or another)
4. Enter the password and save

If the network does not connect, check:

• 🔠 Input accuracy SSID (spaces at the beginning/end are not allowed)
• 🔑 Match encryption type (e.g. WPA2-PSK [AES])
• 📡 Distance to the router (hidden networks are less visible at the edge of the coverage area)

Make sure that the router is actually broadcasting the SSID (check it in its settings)

Restart your router and smartphone

Disable VPN or proxy on your phone

Try connecting from another device to check the network-->

On routers Mi Router The hidden network can be configured in the web interface at 192.168.31.1, in the section Wi-Fi → Wi-Fi Settings → Hide Network (SSID)After applying the changes, the router will reboot and all devices will be disconnected.
