I’m often called upon by my neighbors to troubleshoot their crummy network connections. I already have good advice for solving bad latency caused by bufferbloat but I also hear, “My network connection is weak”, and I would like a nice tool to give me a visual sense of the facts on the ground.

I looked around for tools that will do this. There’s an NetSpot for Android that has a free tier, but I wanted a free version. I found python-wifi-survey-heatmap, but it only runs on Linux.

Then I found wifi-heatmapper that is a Javascript app, and has been customized for macOS, Windows, and Linux. I’m horsing around with it to see what it’ll do.
