How to Secure My WiFi Connection
Wi-Fi connections can be open or secured. When the wireless connection is open, it does not require a password or WEP key to connect. Any computer or device within range of the wireless signal is capable of connecting to the wireless network. Secure Wi-Fi connections use an encryption type, such as WEP or WPA, to password protect the network from those who do not know the password. You can secure your Wi-Fi connection by enabling an encryption type and setting a wireless password.
Open a Web browser, and type the router's IP address into the address bar, then press "Enter." For example, enter "192.168.1.1." Refer to the router's user manual for details.
Enter the router's user name and password, then press "Enter." Common combinations are a blank user name and "admin" for the password, and "admin" for the user name and "password" for the password. Refer to the router's user manual for details.
Click the "Wireless" link. Some routers have a "Security" sub-link.
Click "WPAv2" if available, otherwise click "WPA."
Type a password to use to secure the Wi-Fi connection, then click "Save" or "Apply." Any currently connected wireless clients must disconnect, then reconnect using the new password.
