Wifi connectivity issue with home network

[santoshi]

My Samsung phone keeps having Wi-Fi connectivity issues, while all other devices at home work perfectly. I’ve already tried restarting, forgetting the network, and basic troubleshooting, but the issue keeps coming back.
Please provide a strong and permanent solution for this. It’s getting really frustrating now.
Thank you.

Does your router provide log info that tells you why the connection was dropped?
Some will even provide signal strength (dB) of the connected device, and what the router's threshold is (may be configurable) before it decides to drop a connection.
Are you in a heavy network congested place? e.g. I get very many wifi signals from neighbors, all competing for the same band and channel.
A WiFi Spectrum Analyzer app will show you the situation there.

Try resetting the network on the phone and also rebooting the router. Go to settings/general management/reset/reset Wi-Fi and Bluetooth settings and then reset it. Then after that, power down the device by pressing and holding both the volume down and side (power) buttons at the same time until that option screen appears, then power off.

After powering down, press and hold both the volume up and side buttons at the same time until the recovery screen shows. Then using the volume buttons, move the highlight over "Wipe cache partition", then press the side button. Then use the volume button to highlight "Yes", then press side button. It then will default back to the top "Reboot system now", and just press the side button to restart the device as usual.

Restart the router and after it comes back up, reconnect the phone to the Wi-Fi network.

NOTE: When resetting the connections on the phone, it will also remove all Bluetooth connected devices as well. So anything using BT will have to go through the pairing process again.
