The following sections describe how to use the WiFi connection utility to set up the required
security settings for your WiFi adapter. See Personal Security.
It also provides information about how to configure advanced security settings for your WiFi
adapter. This requires information from a systems administrator (corporate environment) or
advanced security settings on your access point (for home users). See Enterprise Security.
For general information about security settings, See Security Overview.
Set up Data Encryption and Authentication
In a home wireless network you can use a variety of simple security procedures to protect
your wireless connection. These include:
● Enable Wi-Fi Protected Access* (WPA).
● Change your password.
● Change the network name (SSID).
Wi-Fi Protected Access (WPA) encryption provides protection for your data on the network.
WPA uses an encryption key called a pre-shared key (PSK) to encrypt data before
transmission. Enter the same password in all of the computers and access point in your
home or small business network. Only devices that use the same encryption key can access
the network or decrypt the encrypted data transmitted by other computers. The password
automatically initiates the Temporal Key Integrity Protocol (TKIP) or AES-CCMP protocol for
the data encryption process.
Network Keys
WEP encryption provides two levels of security:
● 64-bit key (sometimes referred to as 40-bit)
● 128-bit key (also known as 104-bit)
For improved security, use a 128-bit key. If you use encryption, all wireless devices on your
wireless network must use the same encryption keys.
You can create the key yourself and specify the key length (64-bit or 128-bit) and key index
(the location that a specific key is stored). The greater the key length, the more secure the
key.
Key Length: 64-bit
