Redmi and Realme smartphones have become extremely popular, with millions of users relying on them daily. However, many users have recently reported a frustrating issue: Wi-Fi keeps disconnecting automatically.
The phone connects to Wi-Fi normally but then disconnects after a short time or automatically switches to mobile data without warning. This issue has become more common after recent updates such as Android 15, Realme UI 6, and newer MIUI versions.
What Is the Wi-Fi Auto Disconnect Issue
Wi-Fi auto disconnect refers to a situation where your phone connects to a Wi-Fi network successfully but loses the connection shortly after, without any manual action from the user.
In many cases, the internet may appear connected, but it stops working or drops unexpectedly.
Common scenarios include:
- Wi-Fi disconnects when the screen locks
- Internet drops during video calls or gaming
- Wi-Fi turns off during idle or nighttime use
- Wi-Fi icon shows connected, but no internet access
Which Phones Are Affected
This issue is mostly software-related and is seen in multiple devices, especially after recent updates.
Redmi devices:
- Redmi Note series
- Redmi Number series (13, 14, 15)
- Redmi K series
- POCO devices (MIUI-based models)
Realme devices:
- Realme Narzo series
- Realme Number series
- Realme GT series
- 5G Realme phones after Android 15 updates
Main Causes of Wi-Fi Auto Disconnect in Redmi & Realme Phones
Android 15 and UI Update Bugs
Major system updates often introduce temporary bugs. Android 15 and Realme UI 6 have shown issues in network handling, causing unstable Wi-Fi behavior.
Smart Wi-Fi or Auto Network Switching
Both Redmi and Realme devices include features like Wi-Fi Assistant or Smart Network Switch. These automatically switch to mobile data if Wi-Fi is considered weak, but bugs can trigger unnecessary switching.
Battery Optimization Settings
To save power, smartphones may put Wi-Fi into sleep mode when the screen is off, which leads to disconnection during idle periods.
Router Compatibility Issues
Sometimes the issue is not the phone but the router. Problems like unstable 5GHz signals, outdated firmware, or incorrect channel settings can cause frequent drops.
Corrupted Network Settings
Saved Wi-Fi configurations, DNS conflicts, or outdated network data after updates can also lead to unstable connections.
