How to Fix Xiaomi Phone Proximity Sensor Not Working During Calls
Xiaomi phone mobile hotspot limited connectivity is usually fixed by resetting the hotspot session, checking mobile data access, and correcting APN or band settings. In many cases, Xiaomi hotspot limited connectivity appears when the phone shares a weak mobile data connection, battery restrictions block tethering, or connected devices fail to get a valid IP address.
Steps
-
Restart mobile data and hotspot
Turn off Mobile Data, turn off Hotspot, wait 20 seconds, then enable Mobile Data first and Hotspot second. A fresh session often fixes temporary hotspot internet Xiaomi failures.
-
Check hotspot settings
Open Settings > Portable hotspot and confirm the hotspot is active, the password is correct, and the maximum connected devices limit is not reached. If available, switch between 2.4 GHz and 5 GHz.
-
Verify APN and carrier access
Open Settings > SIM cards & mobile networks > Access Point Names and confirm the active APN matches the carrier default. Incorrect APN values can block mobile data sharing even when normal browsing still works.
-
Disable battery and data restrictions
Open Settings > Apps > System apps > Settings services or related network services and remove battery saver or background data limits if present. MIUI optimization can interrupt tethering after a few minutes.
-
Reset network settings
If hotspot devices connect without internet, reset Wi-Fi, mobile network, and Bluetooth settings. A network reset often clears IP conflicts, broken DNS entries, or old hotspot profiles.
🤔Note:
If mobile data does not work directly on the Xiaomi phone, the hotspot will also fail. Test browsing on the phone before changing advanced hotspot settings.
Common Issues and Fixes
- Connected device shows “Limited connectivity” — Likely cause: invalid IP or DNS assignment. Fix: forget the hotspot on the client device, reconnect, or restart both devices.
- Hotspot connects but internet does not load — Likely cause: mobile data is weak or blocked by the carrier. Fix: test mobile data on the Xiaomi phone first and check tethering support on the SIM plan.
- Hotspot disconnects after screen lock — Likely cause: battery saver or MIUI background restriction. Fix: disable battery optimization for hotspot-related services and keep battery saver off during tethering.
- One device works, another does not — Likely cause: Wi-Fi band incompatibility. Fix: switch hotspot from 5 GHz to 2.4 GHz for older laptops, tablets, or smart devices.
- Internet is very slow — Likely cause: poor 4G/5G signal or too many connected devices. Fix: move to a stronger signal area and reduce the number of hotspot users.
Quick Tips
- Wi-Fi band choice: 2.4 GHz is more compatible; 5 GHz is usually faster but less stable at distance.
- Network tools: VPN, private DNS, or ad-blocking apps on the Xiaomi phone can break mobile data sharing.
- Dual SIM check: Dual SIM models may use the wrong SIM for data; confirm the active data SIM before enabling hotspot.
- Carrier rules: Some carriers limit tethering separately from regular phone data, even with an active data plan.
💡Protip:
If older devices cannot stay connected, switch the hotspot to 2.4 GHz first, then reconnect the client device after forgetting the saved hotspot profile.
Related Questions
Why does Xiaomi hotspot say connected but no internet?
The client device is connected to Wi-Fi, but the Xiaomi phone is not passing mobile data correctly. Common causes include weak signal, wrong APN, carrier tethering limits, or MIUI battery restrictions.
Does resetting network settings delete personal files?
No personal files are removed. Saved Wi-Fi networks, Bluetooth pairings, and mobile network preferences are cleared and must be set again.
