how to use wireshark to troubleshoot network issues

How to take the best possible captures, maximizing signal and reducing noise How to install Wireshark to both take and view captures

Throughout this course, you will open the same captures as the instructor, and use the same techniques he uses to see the same results he gets. Real problems are examined from real network captures, and the techniques used to diagnose these problems are laid bare. Instead, the key skills are trained, with a focus on making sure you understand why this skill is useful, and how the skill is used.

No time is wasted on options or features that are not heavily used. This course is specifically designed to walk you through the mindset and methodology an expert uses to diagnose problems with Wireshark. But when you get done with those courses, you still find yourself wondering “How do I actually use this stuff to resolve problems?” Most courses approach this problem with more overload diving into each menu item and option with detailed explanations. Many engineers, even ones with significant experience, feel powerless and lost when confronted with the sea of data that a network capture can provide.
