I'm someone who learns best visually, and I'm trying to figure out how to map my Wi-Fi network. I've seen that using terminal commands can reveal a lot of information, like the IPs of other devices, their MAC addresses, my own network details, and more. Is there a tool or method available that allows me to visually represent my network? I want to see other devices connected, understand my visibility limitations (like if there are restrictions or isolation in place), and create a comprehensive map. For instance, I noticed that places like Starbucks have various blocks; I'm looking for a way to identify those on my own network as well. Any tips or templates that can help? Thanks!

There’s no standardized template for creating a network map, but you might look into using SNMP (Simple Network Management Protocol). It allows you to get data from devices, but you would need compatible clients. There are also network scanners that try to identify devices and open ports, but you might run into limitations. Without thorough scanning, you can’t really figure out restrictions on systems that aren’t yours. Do be careful though since intense scanning could be illegal in many cases!
You should be careful when scanning networks; it’s generally only legal to do this on your own. If you’re exploring places like Starbucks, just keep in mind they have restrictions that could limit what you can see. But for your own situation, it’s good to know you're moving into a space where you’ll pay for Wi-Fi and want to learn about it. Just a heads-up, though, the ultimate goal of mapping the network sounds great for understanding issues like latency, but make sure any tools you use are appropriate for your network.
Thanks for the advice! I really appreciate you clarifying the legality part. I'm definitely sticking to my own network for the mapping.
