Can't detect all the devices on my network

[brianvi]

I know for sure that there are more people than me using the internet, but they aren't listed. I've used Wireless Network Watcher, for example, and it only lists the IP and MAC address of my computer and my router, but not those of the other devices on my network. Please help

Why do you NEED to know? The Router should show connected (DHCP) devices.

If you don't want unauthorized devices to connect to your wireless network then turn on security (WPA2).

WPA2 AES + Long Passphrase

Look in Router...
