python
import subprocess
def block_connection(ip_address):
# Block the connection using firewall rules
command = f"netsh advfirewall firewall add rule name='Blocked Connection' dir=out remoteip={ip_address} action=block"
subprocess.run(command, shell=True)
# Example usage
ip_to_block = "192.168.0.100"
block_connection(ip_to_block)
In the above code, the `block_connection` function takes an IP address as input and uses the `netsh` command-line utility to add a firewall rule that blocks outgoing connections to the specified IP address. The rule is named “Blocked Connection” and is set to block the connection.
Please note that this code is specific to Windows and utilizes the `netsh` command-line utility. Different operating systems may have different methods to interact with firewalls. Additionally, modifying firewall settings may require administrative privileges.
It’s important to exercise caution when working with firewalls and security-related tasks, as incorrect configuration can have unintended consequences.

3. Right-click on your network adapter and select “Disable” from the dropdown menu. Wait a few seconds, then right-click again and select “Enable”.
4. Open the Windows Network Diagnostics tool by clicking on the Start button and typing “network troubleshooter“. Select the “Identify and repair network problems” option.
5. Follow the on-screen instructions to diagnose and fix any network issues.
6. If the issue persists, you may need to reset your firewall settings. Open the Windows Defender Firewall by typing “windows defender firewall” in the Start menu search bar and selecting the matching result.
7. Click on the “Restore defaults” option in the left pane to reset your firewall settings to their original state.
