update the client keys.
◆ WEP Keys — Sets WEP key values. The user must first select ASCII or
hexadecimal keys. Each WEP key has an index number. Enter key values that match
the key type and length settings. Enter 5 alphanumeric characters or 10
hexadecimal digits for 64-bit keys, or enter 13 alphanumeric characters or 26
hexadecimal digits for 128-bit keys. (Default: Hex, no preset value)
Note.
If WEP authentication is selected for WDS communication, you will then only have
one set of encryption for the entire channel.
WPA & WPA2
Wi-Fi Protected Access (WPA) was introduced as an interim solution for the
vulnerability of WEP pending the adoption of a more robust wireless security
standard. WPA2 includes the complete wireless security standard, but also offers
backward compatibility with WPA.
◆ WPA — Clients using WPA for authentication.
◆ WPA2 — Clients using WPA2 for authentication.
◆ WPA-Auto — Clients using WPA or WPA2 for authentication.
◆ WPA Algorithms — Selects the data encryption type to use. (Default is
determined by the Security Mode selected.)
■ TKIP — Uses Temporal Key Integrity Protocol (TKIP) keys for encryption. WPA
specifies TKIP as the data encryption method to replace WEP. TKIP avoids the
problems of WEP static keys by dynamically changing data encryption keys.
■
AES — Uses Advanced Encryption Standard (AES) keys for encryption. WPA2 uses
AES Counter-Mode encryption with Cipher Block Chaining Message Authentication
Code (CBC-MAC) for message integrity. The AES Counter-Mode/CBCMAC Protocol
(AESCCMP) provides extremely robust data confidentiality using a 128- bit key. Use
of AES-CCMP encryption is specified as a standard requirement for WPA2. Before
implementing WPA2 in the network, be sure client devices are upgraded to
