This episode introduces the invisible issues that often plague network performance—factors like wireless interference, signal jitter, and high latency. We begin by explaining electromagnetic interference and how nearby devices, dense walls, or overlapping channels can affect Wi-Fi performance. Then we cover jitter—variability in packet arrival times—which affects voice and video applications most.

We conclude with a discussion of latency, what causes it, and how to measure or reduce it using tools like ping and traceroute. These symptoms often appear in performance-based scenarios where users complain of “slow internet” or “video call issues,” and understanding the terminology is crucial for identifying root causes.
