Step by step

1. 

   Open Network acceleration

   Go to Settings, Wi-Fi, and tap Network acceleration.

   Done

2. 

   Check Switch between networks

   Switch between networks says Switch to mobile data when Wi-Fi signal is weak or network isn't available. It was on on ours. Turn it off if you want the phone to stay on Wi-Fi.

   Done

3. 

   Open the network's details

   Back on the Wi-Fi page, tap the arrow next to the network you are connected to.

   Done

4. 

   Check Privacy (MAC address)

   Privacy was Use randomised MAC on ours. Tap it to choose Use device MAC instead if your router only lets in known devices.

   Done

5. 

   Forget the network and join again

   At the bottom of the details, Forget network removes the saved password. Join the network again with the password.

   Done

6. 

   Find the reset as a last step

   Go to Settings, More connectivity options. Reset Wi-Fi, mobile networks, and Bluetooth is listed there, below Data usage. It is not on the Wi-Fi page.

   Done

7. 

   Reset network settings

   The page says it resets Wi-Fi, mobile data and Bluetooth settings. Tap Reset settings only if the other steps did not help.

   Done

If you do not see this option

• Reset not on the Wi-Fi page? On our phone it was under More connectivity options, with Wireless display, Data usage and Quick Share.
• No Network acceleration? Xiaomi says these features may not be available on some models and the paths can differ. Source: Generic User Guide for HyperOS 3.0

If this does not work

• Router blocks the phone after a change? A randomised MAC looks like a new device to the router. Use device MAC for that network. Source: Generic User Guide for HyperOS 3.0
• Drops only far from the router? With Switch between networks on, the phone moves to mobile data when the signal is weak. That is the setting doing its job. Source: Generic User Guide for HyperOS 3.0

About this guide

When Wi-Fi drops on a Xiaomi phone, the phone may be switching to mobile data on purpose, or the router may not recognise it. These four settings are where to look.

The screenshots are from our Redmi Note 15 Pro 5G with Xiaomi HyperOS 3.0.308.0 and Android 16, in Light mode. We opened these screens and changed nothing; we did not forget the network or reset anything.

Good to know

Mobile data not working instead? Xiaomi mobile data not working.
