Use the Router's web interface to see Wifi users

Wifi transmitters have tools to help users see the list of devices that are connected to Wifi. What you need to do is access the router's web interface to find that list. First, enter the router's IP address into the address bar of the browser. On Windows, you can find the IP address of the router by accessing the command prompt (press the Win + R combination and then enter "cmd" ), then enter ipconfig in the window that appears. Find the "Default Gateway" line and this is the router's IP address . On the Mac, go to Network Preference and the IP address of the Wifi transmitter is the address next to the "Router" section .

After entering, you will be prompted to login to the router account. This account is often accompanied by instructions when buying a transmitter, and usually has a username and password "admin" . Note that if you have not changed the password of this account, you should replace it immediately if you do not want to be exploited by a hacker.

After entering the web interface, you find the items related to the list of connected devices. Here we can only say that in general because the location of this list will depend on the manufacturer's router. For example, Netgear 's router will be "Attached Devices" , or some other router is called "Device List" . Here you will be provided with a list of IP addresses, Mac addresses, and device names (if the router recognizes them) connecting to the Wifi network. You compare this list with your devices to see if Wifi is being used by strangers.

Note: Many people assume that the DHCP list on the router also shows the devices that are connected to Wifi, but this is not true. DHCP - the automatic configuration protocol for IP addresses, only showing DHCP clients: Devices that receive the automatic IP address provided by the router. If he encounters a slightly hefty hacker, he can access Wifi using static IP to bypass the list of DHCP.
