There could be several reasons behind the weak and unstable Wi-Fi signal on your Xiaomi Redmi 4. Here are some possible explanations:

1. Distance from the router: If you are far away from the Wi-Fi router, the signal strength may weaken, resulting in a weak connection. Try moving closer to the router to improve the Wi-Fi signal.
2. Router issues: The problem may lie with the router itself. It could be outdated, not properly configured, or experiencing technical difficulties. Restarting the router or updating its firmware may help improve the Wi-Fi connection.
3. Network congestion: If you are in an area with many Wi-Fi networks or a crowded environment, network congestion can affect the performance of your Wi-Fi connection. This can result in a weaker signal and unstable connection. Changing the Wi-Fi channel on your router settings may alleviate this issue.
4. Interference and obstacles: Physical objects such as walls, furniture, and other electronic devices can obstruct the Wi-Fi signal, leading to a weaker connection. Additionally, other electronic devices operating on the same frequency, such as cordless phones or microwave ovens, can cause interference. Ensure that there are no major obstructions between your device and the router, and try to minimize the number of potential sources of interference.
5. Software or firmware issues: It's possible that there are software or firmware glitches on your Xiaomi Redmi 4 that are affecting the Wi-Fi connection. Ensure that your device has the latest software updates installed. If the issue persists, you may need to consider performing a factory reset or contacting Xiaomi support for further assistance or troubleshooting steps specific to your device model.
6. Wi-Fi sleep settings: Some devices have a feature called "Wi-Fi sleep" or "Keep Wi-Fi on during sleep" that conserves battery by temporarily disabling Wi-Fi when the device is idle. If this feature is enabled, it may cause the Wi-Fi signal to become unstable or disconnect frequently. Check your device's settings and ensure that Wi-Fi is set to stay connected during sleep or idle periods.
7. Hardware limitations: The Xiaomi Redmi 4 is an older device, and its Wi-Fi capabilities may not be as advanced as those of newer models. Certain hardware configurations or antenna placements may contribute to weaker signals and unstable connections. In such cases, optimizing the placement of your device or using a Wi-Fi range extender may help improve the Wi-Fi connectivity.

Considering these possibilities, it's recommended to try the basic troubleshooting steps first, such as moving closer to the router, minimizing interference, and restarting the router. If the issue persists, you can explore further options, such as updating firmware, changing router settings, performing a factory reset, or contacting Xiaomi support for specific guidance on your device model.
