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
