What do crosstalk, jitter, reflection, and interference have in common? They all cause problems with networks. In this course, you will discover how to troubleshoot common wired and wireless connectivity issues related to attenuation, latency, crosstalk, electromagnetic interference (EMI), opens, shorts, crossed connections, transceiver mismatches and bad ports. Other issues include bottlenecks, VLAN mismatches, damaged cables, and bent pins. Additionally, you will learn how to troubleshoot incorrect antenna types and antenna placements; look at interference, overcapacity, channel overlap, distance limitations, frequency mismatches, wrong SSIDs, and mangled passphrases. Conclude by considering security type mismatches, power levels, and the need for optimized signal to noise ratios

By using the appropriate troubleshooting tools, network problems can be identified and resolved quickly. In this course, you will learn how to quickly identify problems, establish a cause, test theories, determine a plan of action, and recognize potential effects of the treatment. Begin by finding out how to implement an appropriate solution or escalate it, if required. Next, verify that things work after the solution. This involves documenting findings, actions, and outcomes. Conclude by reviewing troubleshooting equipment and software tools, such as network testers, packet sniffers, WiFi analyzers, bandwidth speed testers, command line tools, and Linux commands
