
Auth Type: In the drop-down list, choose an authentication method. The options are Open System or
Shared Key .
o
If you choose Open System , any client will be able to authenticate, as long as it conforms to any
MAC address filter policies you have set. In an open system, authentication packets are sent
without encryption.
o
If you choose Shared Key , the W7x sends a challenge text string (unencrypted) to devices that try
to communicate with the access point. The device that requests authentication encrypts the
challenge text and returns it to the access point. If the challenge text is correctly encrypted, the
access point authenticates the requesting device.
If you don’t know which authentication type will be used, it’s recommended to select Auto .

Input Type : Select Hex or ASCII .

Key Length : Choose a key length. 64-bit hex keys require 10 characters, and 128-bit keys require 26

WPA-PSK, WPA2-PSK
When you select a wireless security Type , the configuration options for that mode appear.
WPA (Wi-Fi Protected Access) improves on the security features of WEP (Wired Equivalent Privacy). WPA
technology can work with existing Wi-Fi products that are enabled with WEP. WPA improves data encryption using
the Temporal Key Integrity Protocol (TKIP), which scrambles the encryption keys using a hashing algorithm, and
adds integrity checking to ensure that keys haven’t been tampered with.
If your wireless network uses WPA security with a pre-shared key (PSK) , select WPA-PSK or WPA2-PSK from the
Type drop-down list. If your network doesn’t use a PSK, see the following section.
