1 Understand the problem

Before you can solve a problem, you have to understand it. This means you have to gather as much information as possible about the symptoms, the scope, the impact, and the possible causes of the problem. You can use tools such as ping, traceroute, ipconfig, netstat, wireshark, and nmap to test connectivity, verify configurations, monitor traffic, and scan ports. You can also consult documentation, logs, reports, and users to get more details and clues.

Adopting a structured approach: Gather data, identify symptoms, isolate the issue, test solutions, and document everything. Understanding core networking principles: TCP/IP, DNS, routing, switching, etc., form the foundation for diagnosing problems. Leveraging diagnostic tools: Ping, traceroute, packet captures, logs, and monitoring systems are your allies. Staying updated: Technologies and threats evolve, so continuous learning is crucial. Remember, problem-solving is an iterative process. Don't get discouraged if the first solution doesn't work. Analyze, adapt, and try again! This should come in under 750 characters, leaving room for you to personalize it with your specific goals and learning style.

First of all, you should check the patch-cord and NIC configuration. After that, we are ready to use different tools. If the physical connection is good you need check next-hop device.

2 Isolate the cause

Once you have a clear picture of the problem, you have to narrow down the possible causes and identify the root cause. You can use a process of elimination, a divide-and-conquer strategy, or a hypothesis-testing method to isolate the cause. For example, you can start by checking the physical layer, then the data link layer, then the network layer, and so on until you find the faulty component or configuration. Alternatively, you can split the network into smaller segments and test each one until you locate the problem area. Or, you can formulate a hypothesis based on the symptoms and test it with evidence.

3 Implement a solution

After you isolate the cause, you have to implement a solution that resolves the problem and restores the network functionality. You have to choose a solution that is feasible, effective, and appropriate for the situation. You also have to consider the potential risks and impacts of the solution on the network performance, security, and users. You have to follow the change management procedures and document the steps and results of the solution.

4 Verify the results

Once you implement a solution, you have to verify that it works and that it does not create new problems. You have to test the network connectivity, functionality, and performance using the same tools and methods that you used to diagnose the problem. You have to compare the before and after results and check if they match your expectations and goals. You also have to monitor the network for any anomalies, errors, or issues that may indicate unresolved or new problems.

5 Learn from the experience

The final step in network troubleshooting is to learn from the experience and improve your skills and knowledge. You have to review the problem-solving process and evaluate your actions and decisions. You have to identify what worked well and what did not work well. You have to analyze the root cause and the solution and see if they can help you prevent or solve similar problems in the future. You also have to update your documentation, records, and tools with the relevant information and feedback.

By following these steps, you can develop a systematic and logical approach to network troubleshooting that will help you solve problems better and faster. You will also enhance your computer networking skills and knowledge and become a more competent and confident network engineer.

The first step in solving networking problems better is to clearly understand the issue. Gather all relevant information, analyze it, and come up with a plan. Implement the plan carefully, test the solution, and document everything for future reference. Finally, review the process to learn from it and improve your problem-solving skills.

Network monitoring is essential. Know about issues before users do. Understand & remediate whatever is 'orange' BEFORE it goes 'red' and impacts the business. Be proactive and in control of your empire rather than assuming all is ok!
