How can I find out who is stealing my WiFi ? [Solved]

Do you feel that your high speed connection is bogged down, and you are getting a creepy feeling that someone’s stealing your bandwidth on your Wi-Fi network.

WiFiWireless network connections have become popular in past years, thanks to an increasing number of devices that utilize wireless connections. But there is a problem associated with it, or more precisely with the securing of wireless routers and devices to block unauthorized access: The device needs to use proper encryption to block third parties from accessing it. Many users do not know the differences between WEP or WPA encryption, or which of the encryption schemes they should select for best security.

That could leave their wireless routers open for unauthorized access, especially if no encryption or weak encryption is configured.
