Detect Outside User on Your Wireless Network

Here is the procedure of how you can detect an outside user is on your wireless network.

• Open your web browser and input your default gateway’s IP address.
• • Go to Start > run, and type cmd
  • Type ipconfig and press enter. It will list the default gateway. Once you have your default gateway address, open your web browser and type it in the URL bar
• Input your router’s username and password.
• • Default for Dlink routers is Username: Admin; Password: (blank)
  • Default for Netgear routers is Username: admin password: password
  • Default for Linksys products is usually username: (blank) password: admin
  • Default for Siemens routers is Username: Admin; Password: admin (all lowercase).
  • Default User Names and Passwords can be found sometimes under the router, on the label or using Google.
• If you are using the default username and password, go to the Administration tab to change it to something more secure.  From the Router’s user interface you will probably have a setting to log Users going through the router-enable it.
• Use the steps shown above finding the default gateway to find your MAC or also called physical address of all computers/devices that use wireless in your home or that will be using it. From time to time check the log to see if any unknown addresses show up. If so, then someone is leeching off your internet. MAC/physical addresses are unique hexadecimal code that identifies each Network card inside every PC that uses Ethernet. No two MAC addresses are the same.
