How to Tell If Someone Is Stealing Your Wireless Internet Signal?

When the Internet slows down, many people blame viruses or a faulty wireless connection. If the wireless connection is not protected by a password, however, anyone with a wireless router can pick up that connection, using it to browse the Internet for free. This overloads the wireless connection, increasing lag time and random disconnects. Computer users can find out if their Internet connection is being stolen by installing Zamzon Wireless Network Tool and scanning their wireless connection for additional Internet protocol addresses.

Step

Note if the Internet connection slows down dramatically or disconnects during specific times every day. For example, if the Internet connection slows down from 3 p.m. to 5 p.m. every day, note it on a piece of paper.

Step

Start Zamzom Wireless Network Tool. Write down the number it lists as your IP address. Click the "Fast Scan" button to have it scan for all IP addresses connected to your wireless connection, preferably during the time when the Internet slows down.

Step

Look in the text box below "Fast Scan" to see if any additional IP addresses are listed. If there are IP addresses listed not matching your IP address number, somebody else is using your wireless connection. Click the "X" button in the upper right corner to exit the program.
