That spinning Wi-Fi icon on your Xiaomi 15 is incredibly frustrating, especially when you know you have a fast connection. This is a common hiccup with HyperOS 2, but the good news is you can almost always fix it yourself in a few minutes.
Toggle Wi-Fi and Restart Your Phone
Swipe down from the top of your screen to open the Control Center and tap the Wi-Fi icon to turn it off. Wait five seconds, then tap it again to turn it back on. This simple refresh forces your phone to search for networks again and often solves the issue right away.
If the icon is still spinning, give your Xiaomi 15 a full restart. Press and hold the power button until the power menu appears, then tap "Restart." A reboot clears out any temporary glitches in HyperOS that might be blocking the connection.
Use Airplane Mode to Reset All Radios
When a simple toggle doesn't work, a broader reset can help. Pull down the Control Center and tap the airplane icon to enable Airplane Mode. Wait about 15 seconds, then tap it again to disable it. This shuts down and restarts the Wi-Fi, Bluetooth, and cellular radios together, which can resolve deeper conflicts.
Forget the Problem Network
Your phone might be holding onto corrupted login data for your network. Go to Settings > Connections & sharing > Wi-Fi. Tap on the network name you're trying to use and select "Forget network." Now, find the network in the list again, tap it, and re-enter the password to connect fresh.
This is the fix you need if you've recently changed your Wi-Fi password or gotten a new router. Your Xiaomi 15 won't connect because it's stubbornly using the old, incorrect credentials.
Check for Simple Mistakes
It sounds basic, but it's worth verifying. Make sure you're selecting the correct network name from the list, especially if you have a dual-band router with both 2.4GHz and 5GHz networks available. Also, double-check that you're entering the password correctly, Wi-Fi passwords are case-sensitive, so watch for caps lock.
Disable Bluetooth Temporarily
Bluetooth and Wi-Fi can sometimes interfere with each other on the 2.4GHz band. Try turning off Bluetooth from your Control Center and see if your Wi-Fi connection stabilizes. If it does, you've found a simple workaround for when you need a reliable internet connection.
Turn Off Smart Network Features
HyperOS includes features designed to save data or battery that can accidentally hinder Wi-Fi. Go to Settings > Connections & sharing > Wi-Fi, then tap the menu icon (three dots) and go to Wi-Fi Assistant. Here, you can disable options like "Auto-switch to mobile data" which might be prematurely abandoning your Wi-Fi signal.
Check Power Saving and Performance Modes
If you have Battery Saver or a custom performance profile enabled, it might be limiting background network activity to conserve power. Go to Settings > Battery and make sure any power-saving mode is turned off. Also, if you're using Game Turbo mode, try exiting it, as its network optimization can sometimes behave unpredictably.
Update Your Xiaomi 15 Software
Outdated software is a common source of bugs, including Wi-Fi problems. Xiaomi regularly releases updates for HyperOS that fix connectivity issues. Go to Settings > About phone > HyperOS version and tap "Check for updates." Install any available update and restart your phone.
Verify Your Date and Time Settings
An incorrect system time can break Wi-Fi authentication because security certificates won't validate. Go to Settings > Additional settings > Date & time. Make sure "Set time automatically" is switched on. This syncs your phone's clock with network time and can resolve stubborn connection failures.
Reset Your Network Settings
If you're still stuck, resetting all network settings is a strong next step. This will erase all saved Wi-Fi networks, Bluetooth pairings, and VPN settings. Go to Settings > Additional settings > Back up and reset > Reset phone. Here, tap "Reset Wi-Fi, mobile & Bluetooth." You'll need to reconnect to your Wi-Fi and re-pair Bluetooth devices afterward.
Restart Your Wi-Fi Router
The problem might not be your phone at all. Unplug your router from power, wait a full 60 seconds, and plug it back in. This gives it a clean reboot. If other devices in your home also can't connect, the router is almost certainly the culprit. While you're at it, check your router's admin page to see if a firmware update is available.
Boot Into Safe Mode
A third-party app you installed could be causing the interference. To check, boot your Xiaomi 15 into Safe Mode. Press and hold the power button, then tap and hold the "Power off" option on your screen until the Safe Mode prompt appears. Tap "OK." If Wi-Fi works perfectly in Safe Mode, a recently installed app (like a VPN, ad blocker, or "cleaner" tool) is likely the cause. You'll need to uninstall apps one by one to find the offender.
Perform a Factory Reset
This is your last resort before considering a hardware issue. A factory reset will wipe your phone back to its original state, so back up everything important first. Go to Settings > Additional settings > Back up and reset > Reset phone and choose "Erase all data (factory reset)." After the reset, set up your phone as new and test the Wi-Fi before restoring your apps and data.
