The netdiscover utility will list all connected hosts on your local LAN. This is useful for scanning a network and determining which hosts are online.

I used this command to scan an IP range starting with 192.168.0.1.

[email protected]:~$ sudo netdiscover -r 192.168.0.1/24

This is a good way to find other hosts and to check if the WIFI network you are using has user isolation on or not… Good if you wish to capture other users packets. Or Wireshark could be used to find other hosts. But give this a try and see how you go with this.
