Turn Wi-Fi On or Off auf Xiaomi
Wi-Fi on a Xiaomi phone runs through MIUI's own connectivity manager, separate from mobile data. If a network never connects automatically, the radio itself may be turned off rather than the specific network being blocked.
To check or change the state, open Settings ➔ tap Wi-Fi ➔ use the switch to enable or disable Wi-Fi. Once enabled, the phone scans for saved and nearby networks; once disabled, it stops all wireless network scanning and connections.
When to turn Wi-Fi off
Switching Wi-Fi off saves battery when you are away from any known network, since the radio no longer searches continuously. It also stops unwanted auto-connects to open public hotspots.
When to leave it on
If you rely on messaging apps, cloud backups, or large downloads at home or work, keep Wi-Fi enabled so the phone can switch away from mobile data automatically.
Note that disabling Wi-Fi does not affect mobile data or Bluetooth. Those run through separate toggles and stay active independently.
