This Is Why You Can’t Get WiFi Signal In That One Room In Your Home

WiFi Apartment

How is it possible that you got this powerful router, and yet this one bathroom on the second floor never gets any darn WiFi? Jason Cole, a PhD student in physics wondered the same thing, but instead of cursing at his phone like most of us do, he decided to investigate. The picture above is the result of his efforts. After “mapping his own apartment and assigning refraction values to the walls, then applying so-called Hemholtz equations to model the electromagnetic waves’, he obtained a clearer view of what happens to the signal as the router is moved around. And while he did determine that the most optimal spot to place it was in the center of his apartment, he couldn’t do that, so he used his work to find the second best spot, one which would generate the most “tendrils” of coverage to the most places.

While most of us don’t have the knowledge to find the optimal spot for our router, the image above does highlight the fact that moving things around even just a little bit can make a rather large difference and that after some trial and error, you may be able to improve your situation dramatically.
