    Hi
    In your wifi router it should show a list of users connected in something like 'Wireless Access Control' or the likes....

    Hi
    You can always use nmap as well.... It will show everything on the network;

    Code:
    ip route (for ip range and netmask)
    nmap -sn xxx.xxx.xxx.xxx/xx
    or
    nmap -sn `ip route | grep -m2 "src" |cut -f1 -d"d"`

    I use sudo iotop -i wlan0 (put your wifi interface name here if wlan0 is not what you have)
    It will show everyone using you wifi - you'll be shocked at how many linux apps talk on the internet.
    Opensuse 15.1 with VirtualBox VM's (Windows 98, XP, 7, 8.1, 10 & OpenSUSE 15.0)

    Unix since 1974 (pdp-11 in "B" , Interdata 7/32 in "C") (AT&T, Tandy, Convergent, IBM, NCR, HP flavors)
    Linux since 1995 (mandrake, redhat, fedora, centos, now OpenSUSE)

    Question Re: Detect wifi users

    What is your WiFi access point?
    • The Linux systems?
    • A Router which is connected to an ISP?

    For the case of the Linux systems, the previous answers have to be considered plus:
    • A rigorous inspection of the systemd journal;
    • Continuous monitoring of the WiFi interface with Wireshark – you'll have to setup filters to inspect for attempts to access the wireless interface.

    For the case of a Router connected to your ISP it's a little bit easier:
    • Inspect the Router's WiFi administration for the list of MACs which have accessed the wireless channel's SSID – check that list against the MAC addresses of your devices.
    • Consider only allowing access for known MAC addresses – a bit of a pain when visitor arrives – you'll have to specifically add that MAC address to the list of allowed addresses …
