🔹 Why Xiaomi Phones Disconnect from Wi-Fi Automatically
One of the most frustrating issues for Xiaomi, Redmi, and POCO users is when the Wi-Fi keeps disconnecting automatically — especially while streaming, gaming, or downloading updates.
In most cases, this isn’t a hardware problem but rather a MIUI configuration issue.
The built-in “Wi-Fi Assistant” feature is designed to automatically switch between Wi-Fi and mobile data to maintain a stable internet connection.
However, on many Xiaomi devices, this causes random Wi-Fi dropouts even when the network is fine.
🔹 Step-by-Step: Stop Xiaomi from Disconnecting Automatically
Follow these exact steps to keep your Wi-Fi connection stable:
Step 1: Open Wi-Fi Assistant Settings
-
Open Settings.
-
Tap Wi-Fi.
-
Scroll down and select Additional settings (on MIUI 13 and above, it may appear as “Wi-Fi Assistant”).
→ Menu path:
Settings › Wi-Fi › Wi-Fi Assistant
Step 2: Disable Network Auto-Switching
-
In the Wi-Fi Assistant menu, find “Select best networks automatically” or “Switch to mobile data when Wi-Fi is unstable.”
-
Turn this option off.
This setting forces MIUI to stay connected to your current Wi-Fi network, even if the signal weakens temporarily.
🔹 Step-by-Step (Alternative MIUI Versions)
Depending on your MIUI version, the path might differ slightly:
-
MIUI 14 or later:
Settings › Connection & sharing › Wi-Fi Assistant › Disable “Switch to mobile data automatically.”
-
Older MIUI (11–12):
Settings › Wi-Fi › Advanced settings › Turn off “Automatically switch to mobile data.”
🔹 Additional Fixes if Wi-Fi Still Disconnects
If turning off Wi-Fi Assistant doesn’t solve it, try these in order:
1. Forget and Reconnect to Your Wi-Fi Network
-
Go to Settings › Wi-Fi › [Your Network] › Forget Network
-
Then reconnect and re-enter the password.
2. Reset Network Settings
-
Open Settings › Connection & sharing › Reset Wi-Fi, mobile networks, and Bluetooth.
This clears any corrupted network profiles that can trigger disconnections.
3. Turn Off Battery Saver for Wi-Fi Apps
-
Go to Settings › Battery › Battery saver › [App name] › No restrictions.
Some Xiaomi power-saving modes can pause Wi-Fi connections in the background.
4. Update MIUI
-
Go to Settings › About phone › MIUI version › Check for updates.
Xiaomi frequently patches network bugs through system updates.
5. (Last Resort) Factory Reset
If nothing else works:
-
Backup your data to Mi Cloud or a PC.
-
Go to Settings › About phone › Factory reset › Erase all data.
🔹 Pro Tips to Maintain a Stable Wi-Fi Connection
✅ Keep your router firmware updated.
✅ Avoid using battery saver during long downloads or streaming.
✅ Don’t enable both “Dual Wi-Fi Acceleration” and “Data switching” simultaneously.
✅ Reboot your router once a week to refresh the IP lease.
🔹 Summary: Quick Fix Checklist
Step | Action | Path |
---|---|---|
1 | Disable “Switch to mobile data” | Settings › Wi-Fi › Wi-Fi Assistant |
2 | Forget & reconnect | Settings › Wi-Fi › [Your Network] |
3 | Reset network settings | Settings › Connection & sharing › Reset Wi-Fi… |
