This may sound funny - but it works!!
Most people in the neighborhood, who are connecting to your Wi-Fi network without permission, could be doing so unintentionally just because their computer showed them that an open wireless network in available in that area.
The data LED of your wireless router is constantly blinking and none of the family members are using the Internet at home. This might indicate that someone outside – probably one of your neighbors – is enjoying the web using your Wireless network.
To change the SSID of your wireless router, log in to your router’s admin console and rename the network under Basic Wireless setting as shown in this screenshot.
[*] Find the MAC Address of your devices
If you type “ipconfig /all” at the command prompt, you can easily find the MAC address of your computer’s network card – just look for the string “Physical Address.” The Wi-Fi Mac address of mobile devices is often listed on their Settings page.
The MAC Addresses are also listed inside the DHCP Client Table of your router.
