How to Prevent People from Stealing your Wi-Fi Network

Are neighbors piggybacking on your Wi-Fi network? Learn about simple ways to prevent neighbors from using your wireless Internet without permission. 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 your neighbors – are surfing the web using your Wireless (Wi-Fi) network.

Are neighbors using your Wi-Fi network?

If you would like to confirm whether an outsider is using your wireless home network, here’s a trick. First enter the router’s IP address in the browser’s address bar – here’s how to find the router’s IP Address. Then open the DHCP Client Table (it is under Status – > Local Network – > DHCP Server for Linksys routers). This shows a list of all devices connected to your wireless network including those of strangers.

How to Prevent Wi-Fi Theft

You can’t block the Wi-Fi signals from reaching your neighbor’s house but there are several things you may do to prevent them from piggybacking on your wireless network. Some of the well-known techniques to secure your Wireless networkinclude:

1. Setup a password for your Wi-Fi network – Open your router’s admin dashboard and set the wireless security mode to either WPA, WPA2 or WEP (use WPA2-mixed if possible). Now people would have to know the password before they can join your Wi-Fi network.

2. Use MAC Address Filtering – Your laptop computer, mobile phone, tablet and all other gadgets have a unique MAC address. Go to your router’s dashboard and under the Wireless Mac Filter section, add the MAC addresses of all your known devices so that only whitelisted devices can access your wireless Internet.
