6.The Wireless Security screen will appear. Select WEP, WPA-PSK, WPA Radius, or Radius for the Encryption Method. WEP stands for Wired Equivalent Privacy, WPA-PSK stands for Wi-Fi Protected Access Pre-Shared Key, which is a security standard stronger than WEP encryption, and RADIUS stands for Remote Authentication Dial-In User Service. If you don’t want to use encryption, select Disabled. Then, click Next to continue or Back to return to the previous screen.
WEP
Security - To use WEP encryption, select 64-bits or 128-bit characters from the drop-down menu, and enter a passphrase or key.
Passphrase - Instead of manually entering a WEP key, you can enter a passphrase in the Passphrase field, so a WEP key is automatically generated. It is case-sensitive and should not be longer than 16 alphanumeric characters. This passphrase must match the passphrase of your other wireless network devices and is compatible with Linksys wireless products only. (If you have any non-Linksys wireless products, enter the WEP key manually on those products.)
Transmit Key - The default transmit key number is 1. If your network’s access point or wireless router uses transmit key number 2, 3, or 4, select the appropriate number from the Transmit Key drop-down box.
Key 1- The WEP key you enter must match the WEP key of your wireless network. If you are using 64-bit WEP encryption, then the key must consist of exactly 10 hexadecimal characters. If you are using 128-bit WEP encryption, then the key must consist of exactly 26 hexadecimal characters. Valid hexadecimal characters are “0” to “9” and “A” to “F”.
Authentication -The default is set to Auto, where it auto-detects for Shared Key or Open system. Shared Key is when both the sender and the recipient share a WEP key for authentication. Open key is when the sender and the recipient do not share a WEP key for authentication. All points on your network must use the same authentication type.

passphrase: used much like a password, a passphrase simplifies the WEP encryption process by automatically generating the WEP encryption keys for Linksys products
