If you're experiencing weak and unstable Wi-Fi connection on your Samsung Galaxy J7+, there are several troubleshooting steps you can follow to try and resolve the issue:

Samsung Galaxy J7+

1. Restart your device: Begin by turning off your Galaxy J7+ and then turning it back on. This simple step can often help resolve minor connectivity issues.
2. Move closer to the Wi-Fi router: Ensure that you are within a reasonable range of your Wi-Fi router. Walls and other physical barriers can weaken the signal, so try moving closer to the router to see if the connection improves.
3. Check Wi-Fi signal strength: Check the signal strength of your Wi-Fi network on your Galaxy J7+. If the signal is weak, you might need to consider using a Wi-Fi extender or repositioning your router for better coverage.
4. Forget and reconnect to the Wi-Fi network: On your Galaxy J7+, go to Settings > Wi-Fi, and locate the network you're having trouble with. Tap and hold on the network, then select "Forget" or "Forget network." Afterward, reconnect to the network by entering the password.
5. Reset network settings: Go to Settings > General Management > Reset > Reset Network Settings. This will erase all saved Wi-Fi networks on your device, so make sure you have the necessary passwords to reconnect afterward. After the reset, set up your Wi-Fi connection again and check if the issue is resolved.
6. Update device software: Keeping your device's software up to date is crucial for optimal performance. Check for any available software updates by going to Settings > Software update > Download and install.
7. Check for Wi-Fi interference: Other electronic devices or neighboring networks might be causing interference with your Wi-Fi signal. Try moving away from devices like cordless phones, microwave ovens, or Bluetooth devices. Additionally, change the Wi-Fi channel on your router to avoid interference from nearby networks.
8. Safe mode: Booting your Galaxy J7+ in safe mode can help determine if any third-party apps are causing the Wi-Fi issue. To enter safe mode, press and hold the power button until the power options menu appears. Then press and hold the "Power off" option until a prompt appears to restart in safe mode. If the Wi-Fi connection stabilizes in safe mode, it's likely that an app is causing the problem. Uninstall recently installed apps or use a process of elimination to identify the culprit.
9. Factory reset: If all else fails, you can perform a factory reset on your Galaxy J7+. Note that this will erase all data and settings on your device, so make sure to back up your important information before proceeding. To perform a factory reset, go to Settings > General Management > Reset > Factory data reset.

If the issue persists even after following these troubleshooting steps, it might be worth contacting Samsung support or your internet service provider for further assistance.
