When troubleshooting a network connectivity issue, an IT Support Engineer would typically follow these essential steps:

1. Check Physical Connections: Inspect cables, connectors, and network equipment to ensure everything is properly connected and functioning.
2. Confirm Network Settings: Verify IP configurations, subnet masks, DNS settings, and gateway addresses in the network configuration settings.
3. Test Connectivity: Use network testing tools like ping or traceroute to check connectivity between devices on the network.
4. Restart Devices: Reboot the network devices including routers, switches, and modems to refresh connections.
5. Check for Software Issues: Investigate firewall settings, network protocols, and ensure network drivers are up to date.
6. Review Logs: Analyze network logs for error messages or alerts that may indicate the source of the connectivity problem.
7. Seek Support: If the issue persists, escalate the problem to higher-level support or network administrators for further assistance.

By following these troubleshooting steps systematically, IT Support Engineers can diagnose and resolve network connectivity issues effectively.
