What you'll learn

Unlock the secrets of network diagnostics with this hands-on course, leveraging the power of Wireshark and practical simulation techniques. This course, Network Troubleshooting with Wireshark, provides scenario-driven approaches to identifying and resolving common network connectivity and performance issues that plague modern applications. First, you'll explore identifying and analyzing symptoms of high network latency and packet loss. Next, you'll discover how to pinpoint the source of slow application response times, distinguishing between client, network, and server bottlenecks. Finally, you'll learn to investigate network and application disconnects caused by abrupt TCP resets. By the end of this course, you will be proficient in using Wireshark to interpret packet captures, understand the tell-tale signs of various network faults through practical exercises, and confidently diagnose whether performance problems originate from the client, the network path, or the server infrastructure. You'll gain the practical skills to quickly isolate and troubleshoot even the most elusive network issues.
