A good Wi-Fi connection isn’t just about routers or ISPs or bandwidth — it’s also about wave physics. Today, we’re mapping a Wi-Fi signal throughout an apartment to see how a good connection can go wrong.

And Ill never get that time back
When John, my Verizon Fios technician, set up my new fiber-optic connection, he spoke of a high-speed utopia: no drop-outs, no lag, no worries. Yet after weeks of quarantine-induced dependence on the internet, shaky connections have remained a sadly consistent part of my life. Video calls in my bedroom almost always result in dropouts; even when my computer is physically close to my router, I still freeze in at least one video meeting on most days.
Clearly, great upload and download speeds do not guarantee a great connection. But why? Enter the Verge Scienceteam (and their strange demands). With the help of a psychedelic-looking simulation and a tape measure, we actually charted the course of Wi-Fi waves through my apartment and visualized the science behind my crappy connection. Check out the video above come for the trippy data vis, stay to see what the science team put me through.
