How to Repair Xiaomi Phone That Dropped in Water (Step-by-Step)

Xiaomi hotspot not working or disconnecting is usually caused by mobile data limits, battery restrictions, AP band conflicts, or HyperOS network glitches. A stable fix often comes from restarting tethering, changing hotspot band, disabling battery optimization for system networking, and resetting network settings if the tethering issue on Xiaomi continues.

Steps

Open Settings > Personal hotspot and turn hotspot off, then on again. Also disable and re-enable Mobile data before reconnecting the second device.
Change the hotspot AP band from 5 GHz to 2.4 GHz. Older laptops, smart TVs, and some budget phones often fail to stay connected on 5 GHz.
Check Data usage, Data saver, and any carrier hotspot limit. Xiaomi hotspot not working can happen when mobile data works but tethering is blocked after a limit is reached.
Disable battery restrictions for network-related services and keep Battery Saver off while tethering. HyperOS may stop hotspot sessions in the background to reduce power use.
If hotspot still disconnects, go to Settings > Connection & sharing > Reset Wi-Fi, mobile networks, and Bluetooth. Reconnect all devices after the reset.

🤔Note:

If mobile data itself is unstable, the hotspot will also fail or disconnect. Test browsing on the Xiaomi phone first before troubleshooting tethering settings.

Common Issues and Fixes

Issue	Cause	Fix
Hotspot turns on but no internet on connected device	Mobile data session is stalled or carrier tethering is restricted	Toggle airplane mode for 10 seconds, then test mobile data first before enabling hotspot again.
Hotspot disconnects after a few minutes	Battery optimization or screen-off power management is cutting tethering	Disable Battery Saver and keep the phone unlocked during testing.
Device cannot find Xiaomi hotspot	5 GHz band or hidden SSID causes compatibility problems	Switch to 2.4 GHz and make sure hotspot visibility is enabled.
Connected device shows “Obtaining IP address”	DHCP conflict or saved bad network profile exists	Forget the hotspot on the client device and reconnect with a fresh password.
Fix hotspot HyperOS problem after update	Update changed network settings or created a system bug	Install the latest security patch and reset network settings if the issue started right after updating.

Quick Tips

Rename the hotspot SSID: Set a new password after major system updates because saved client profiles can cause repeated disconnect loops.
Check dual SIM settings: Dual SIM setups can create a tethering issue on Xiaomi when the wrong SIM is selected for mobile data.
Test USB tethering: If USB tethering works, the issue is more likely related to Wi-Fi hotspot settings than mobile data itself.
Review carrier limits: Some carriers allow mobile data but limit tethering speed or duration, even when signal strength looks normal.

💡Protip:

When troubleshooting, switch the hotspot to 2.4 GHz first. It is the fastest compatibility check for older laptops, TVs, and lower-end phones that may not stay connected on 5 GHz.

Why does Xiaomi hotspot keep turning off?

Automatic power saving, overheating, or background network restrictions are common causes. Battery Saver and thermal protection often interrupt long hotspot sessions.

Does HyperOS affect hotspot stability?

Yes. HyperOS can change battery, background, and network behavior after updates. A reset of network settings is a common fix when hotspot problems begin only after a HyperOS upgrade.
