What could be causing my Samsung Galaxy E5 to have poor Wi-Fi reception and frequently disconnect from the network?

There could be several reasons for poor Wi-Fi reception and frequent disconnection on your Samsung Galaxy E5, including:

1. Signal interference: Interference from other electronic devices, walls, or physical obstructions can weaken Wi-Fi signals and cause connectivity issues.
2. Outdated firmware or software: If your phone is running an outdated firmware or software version, it can cause issues with Wi-Fi connectivity.
3. Router configuration: If the router is not configured correctly, it can cause issues with Wi-Fi connectivity.
4. Network congestion: If there are too many devices connected to the network, it can cause slow or unstable connectivity.
5. Hardware problems: If there are any hardware issues with your phone's Wi-Fi antenna or related components, it can cause poor Wi-Fi reception and frequent disconnection.

To troubleshoot the issue, you can try the following steps:

1. Move closer to the Wi-Fi router and check if the signal strength improves.
2. Restart your phone and router.
3. Update your phone's firmware and software to the latest version.
4. Reset your router to its default settings and reconfigure it.
5. Reduce the number of devices connected to the network.
6. Contact Samsung customer support or a professional repair service if the issue persists.
7. Forget and reconnect to the Wi-Fi network: Sometimes, forgetting the Wi-Fi network and then reconnecting to it can resolve connectivity issues. To do this, go to Settings > Wi-Fi, find the network you're having issues with, tap on it, and select "Forget". Then, reconnect to the network by selecting it and entering the password.
8. Disable Power Saving mode: Power Saving mode can cause your phone to disable Wi-Fi when the screen is off, which can cause disconnections. To disable Power Saving mode, go to Settings > Device maintenance > Battery > Power Saving mode and turn it off.
9. Check for app conflicts: Some apps can interfere with Wi-Fi connectivity. To check if this is the case, boot your phone in safe mode (press and hold the power button, then press and hold "Power off" until the "Reboot to safe mode" option appears, then tap on it). In safe mode, only pre-installed apps will be available. Check if the Wi-Fi connectivity issue persists. If it doesn't, then an app you installed might be causing the issue.
10. Perform a factory reset: If all else fails, performing a factory reset can resolve most software-related issues. Before doing so, make sure to back up your data, as a factory reset will erase all data from your phone. To perform a factory reset, go to Settings > General management > Reset > Factory data reset.

If the issue still persists after trying these steps, it may be a hardware problem. In this case, you may need to bring your phone to a repair center or contact Samsung customer support for further assistance.
