Tools: How I Finally Understood Wi-Fi (Hint: It's Like a Rhythm Game)

How invisible waves carry your Netflix streams, Zoom calls, and Spotify playlists without getting mixed up? I was troubleshooting my router when this question hit me. The technical explanations didn't click—until I thought of rhythm games. My Buffalo router (WXR-1750DHP2) kept dropping connection. It would disconnect randomly, then reconnect a few minutes later. Classic intermittent issue. I switched to my ISP-provided modem/router combo (KAON from J:COM) and the speed actually improved. That's when I realized: my 10-year-old router was the bottleneck. But more importantly, it made me wonder: How does Wi-Fi even work? "Wi-Fi uses radio waves to transmit information. It converts digital signals (0s and 1s) into electromagnetic waves through modulation. Wi-Fi 5 uses 256-QAM, while Wi-Fi 6 uses 1024-QAM..." I had no idea what that meant. "Modulation"? "256-QAM"? "1024 patterns"? Sure, I understood waves carry information, but how? Then I thought of rhythm games—like Taiko no Tatsujin (Taiko Drum Master), Guitar Hero, or Rock Band. This is exactly how Wi-Fi works. Wi-Fi 6 can process 4x more detailed patterns than Wi-Fi 5. Imagine playing an expert-level rhythm game where notes fly by so fast you can barely see them. That's what Wi-Fi does billions of times per second. When I realized this, it finally made sense. Then I wondered: "How does Wi-Fi handle multiple devices at once?" Wi-Fi 5 handled devices one at a time (like taking turns in a rhythm game). Wi-Fi 6 uses OFDMA (Orthogonal Frequency Division Multiple Access), which lets multiple devices play simultaneously—like an orchestra. Each section plays simultaneously without interference. That's Wi-Fi 6. Wi-Fi 6 is like an orchestra where everyone plays expert-level rhythm game patterns simultaneously. Technical explanations often don't stick because we need our own mental models. Reading "256-QAM modulation" didn't help me. But thinking of rhythm games did. Finding your own analogies is how you truly understand technology. Next time my Wi-Fi drops, instead of just being annoyed, I'll think: "Ah, the rhythm game notes aren't being read correctly." And somehow, that makes it better. 😊 This thought process—from troubleshooting to understanding—is something I write about more on my blog: tielec.blog Templates let you quickly answer FAQs or store snippets for re-use.
