Do you suspect that someone is using your Wi-Fi? There are several ways to find out which devices are connected to your wireless network, and they are all simple no matter how technical you are.

Method 1 of 3:

Using Your Wireless Router

  1. 1
    Open a browser. You can use a web browser to log in to the web interface for your wireless router. You can use the web interface to set up and configure your wireless network and check who is connected to your wireless router.
  2. 2
    Type the IP address of your router in the address bar. This takes you to the web interface for your wireless router. The IP address for your wireless router is going to be different from one make and model to another. Consult the user's manual or the manufacturer's web page to find the specific IP address for your wireless router.
    • Common router IP addresses include 192.168.1.1, and 10.0.0.1.
    • You can find your router's IP address using the Command Prompt on Windows. Open the Start menu and type CMD to display the Command Prompt. Click it to open it. Then type ipconfig /all and press Enter. Look for the IP address to the right of "Default Gateway"

    Enter your username and password. If you haven't changed the username and password, input the default information. This can vary depending on the make and model of your router. Consult the user's manual or manufacturer's web page to find the default username and password for your router.
    • Common usernames and passwords include "admin" and "password".
  4. 4
    Look for a list of devices. You can find a list of connected devices in the web interface for your router. This is going to be different depending on the make and model of your router. It may be under "Connected devices" or "Attached devices" or something similar. This will show the device name and MAC address for each device connected.
    • If you notice any devices that don't belong, be sure to change your Wi-Fi password. Be sure to use WPA2-PSK encryption if it is available. This will force all connected devices to re-enter the new password to reconnect.

    • Every device that connects to the internet has a unique MAC address. Generally, you can find the MAC address for a device in the Settings menu under the Network or Internet Settings, or the about device info. You can find the MAC address for Windows, Mac, iPhone, Samsung Galaxy.

    They will show up on the hotspot's device list. You may have to log into it, or if it is on your phone, it should be displayed in your phone's menu.

    It's possible that it is a device that you don't remember. But it's also possible that you have a network intruder. I would recommend changing your Wi-Fi password (make sure to use WPA2), and then reconnecting all of your devices.
