How to check the active connection to the WiFi network?
Is there any way to get the ip address of some device on the network?
I know the name of the device
And also, is it possible to determine if the device is working as an AP or as a client?

Answer 1

applications such as:
Ip tools, NeX Network Tools, Network Analizer, PingTools, etc., there are a lot of them.
All of them allow you to see poppies, names and ip-addresses, unless of course the clients in the WiFi network are isolated from each other (by default - not isolated).
