I will always recommend the game. But holding to a budget is more important.

Yeah, that method isn’t intended for enterprise work. But someone who isn’t technical can use it to help figure out what’s going on. Not a single person I’ve ever helped with wifi issues wants to map out things with a wifi analyzer. But ask them to use music and people are far more interested. Even as a thought process since (most) people understand how sound works, if they start thinking of wifi as “noise” they can better understand it.

Wifi is just radio. So, having your access point or wifi enabled router surrounded by things is bad for your wifi experience.

To a certain degree, you can do a “poor-mans” way of figuring out how good your wifi would be by just putting a speaker where the wifi should be coming from, then go someplace else in the building and ask yourself, “Can I hear the music still?”. You get an idea of how the wifi is moving about. (Keep in mind, it’s not perfect, but if you don’t want to use apps or specialized equipment and want to wing it… this will work in a pinch). Sound is better than light because wifi will penetrate walls/floors/etc, where light won’t, so you can listen against said surfaces and close doors, etc, to get a general idea of things.
