How to Fix Xiaomi Phone GPS Not Working or Inaccurate

Wi-Fi keeps disconnecting on Xiaomi HyperOS mainly because of network reset issues, battery restrictions, router compatibility, or a temporary HyperOS Wi-Fi bug. The fastest fixes are restarting the phone and router, disabling battery optimization for system networking, resetting Wi-Fi settings, and updating HyperOS and router firmware.

Steps

Restart the phone and router

Power off the Xiaomi phone for 30 seconds. Restart the router fully. Temporary DHCP or channel conflicts often cause Xiaomi WiFi disconnecting after sleep or network switching.
Forget and reconnect to the Wi-Fi network

Open Wi-Fi settings, remove the saved network, then reconnect with the password. Corrupted saved profiles can trigger repeated disconnects on HyperOS.
Turn off battery restrictions for network-related apps

Check battery settings for Wi-Fi, system apps, and frequently used messaging apps. Aggressive background limits in HyperOS can interrupt network stability when the screen is off.
Reset network settings

Use the system reset option for Wi-Fi, mobile network, and Bluetooth. A network reset clears broken DNS, proxy, or IP settings without deleting photos or app data.
Update HyperOS and check router settings

Install the latest system update. If the hyperos wifi bug started after an update, router-side changes may help: switch from auto channel to a fixed channel, separate 2.4GHz and 5GHz bands, or use WPA2/WPA3 mixed mode carefully.

Common Issues and Fixes

Issue	Likely Cause	Fix
Wi-Fi disconnects when the screen locks	Battery saver or background restriction	Disable battery saver, allow background activity, and test with sleep mode active.
Only one network disconnects repeatedly	Router channel or encryption mismatch	Change router channel, use WPA2 temporarily, and retest.
Wi-Fi connects but no internet works	DNS or IP conflict	Reset network settings and reconnect with automatic IP and DNS first.
Problem started after a HyperOS update	HyperOS Wi-Fi bug or cached network conflict	Clear saved Wi-Fi networks, update again if a patch exists, or test in Safe Mode.
Random drops while switching rooms	Weak roaming between bands or mesh nodes	Split 2.4GHz and 5GHz SSIDs or reconnect manually to the stronger band.

Quick Tips

Public Wi-Fi portals: Public Wi-Fi portals can disconnect silently after the login session expires. Reopen the captive portal page and sign in again.
VPN and DNS tools: VPN apps, private DNS, and ad blockers can break Wi-Fi validation on Xiaomi phones. Disable each one briefly for testing.
Wireless interference: Bluetooth and Wi-Fi interference is more common on crowded 2.4GHz networks. Testing on 5GHz can confirm interference.
Factory reset: A factory reset is usually unnecessary unless reset network settings and Safe Mode both fail.

🤔Note:

If Wi-Fi disconnects only on public or office networks, the issue may be related to captive portal expiration, private DNS, VPN apps, or router-side authentication rules rather than a hardware fault on the Xiaomi phone.

Why does Wi-Fi keep disconnecting only on one Xiaomi phone?

The cause is usually local to the device, not the router. Saved network corruption, battery rules, private DNS, or a HyperOS-specific setting is often responsible.

Does resetting network settings delete files?

No. A network reset removes saved Wi-Fi, Bluetooth pairings, and mobile network settings, but it does not erase photos, apps, or documents.

💡Protip:

Before a full reset, a local backup can prevent data loss from repeated troubleshooting. A phone manager such as Dr.Fone can help export important files and device data first.
