I’m currently in a situation where I’m responsible for optimizing the Wi-Fi network in a moderately sized office. The challenge is that some areas have weak or no signal, and we suspect there are dead zones. We need to precisely identify these areas to improve our network coverage.
iStumbler (i think?) on macOS is a good app for signal strength, etc. Free but doesn’t have mapping abilities.
That one still exists? Remember using that one on my Powerbook about 20 years ago 🧓
