Hexadecimal keys are sequences of hexadecimal digits arranged into four
keys. A hexadecimal digit may be a letter from A to F or a number from 0 to
9. This type of encryption is compatible with equipment from other
manufacturers that use Wi-Fi certified 40-bit encryption.

128-bit Encryption Shared Key—This setting is compatible with 3Com
AirConnect products and products from other vendors, including Agere
and Cisco. 128-bit Encryption Shared Key security requires you to set up an

128-bit Dynamic Security Link—This setting requires that you select Access
Point Local Authentication/Encryption option under Security Settings. 128-bit
Dynamic Security Link is the highest level of access point local security,
requiring a user name and password to access the wireless LAN. The user name
and password set up on the access point must match those set up on the
client. Each network session creates a unique, one-time encryption code. If you
choose this type of security, you must also set up the user access list (see
“Setting up a User Access List”). If you check the Require Windows user
authentication check box, clients will be required to enter a user name and
password every time they associate with the network. If you leave this box
unchecked, the system will authenticate clients based on the user access list
and the saved passwords on the clients.
