know the key. The key is a string of characters that you create. When using WEP, you must determine the
level of encryption. The type of encryption determines the key length. 128-bit encryption requires a longer
key than 64-bit encryption. Keys are defined by entering in a string in HEX (hexadecimal - using characters
0-9, A-F) or ASCII (American Standard Code for Information Interchange - alphanumeric characters)
format. ASCII format is provided so you can enter a string that is easier to remember. The ASCII string is
converted to HEX for use over the network. Four keys can be defined so that you can change keys easily. A
default key is selected for use on the network.

Example:
64-bit hexadecimal keys are exactly 10 characters in length. (12345678FA is a valid string of 10 characters
for 64-bit encryption.)
64-bit hexadecimal keys are exactly 10 characters in length. (12345678FA is a valid string of 10 characters

128-bit hexadecimal keys are exactly 26 characters in length. (456FBCDF123400122225271730 is a valid
string of 26 characters for 128-bit encryption.)

WPA-Personal and WPA-Enterprise:
Both of these options select some variant of Wi-Fi Protected Access (WPA) -- security standards published
by the Wi-Fi Alliance. The WPA Mode further refines the variant that the router should employ.

WPA
WPA Mode:
WPA is the older standard; select this option if the clients that will be used with the router only support the
older standard. WPA2 is the newer implementation of the stronger IEEE 802.11i security standard. With
the "WPA2" option, the router tries WPA2 first, but falls back to WPA if the client only supports WPA.
With the "WPA2 Only" option, the router associates only with clients that also support WPA2 security.

Cipher Type:
The encryption algorithm used to secure the data communication. TKIP (Temporal Key Integrity Protocol)
provides per-packet key generation and is based on WEP. AES (Advanced Encryption Standard) is a very
secure block based encryption. With the "TKIP and AES" option, the router negotiates the cipher type with
the client, and uses AES when available.

Group Key Update Interval:
The amount of time before the group key used for broadcast and multicast data is changed.

WPA-Personal
This option uses Wi-Fi Protected Access with a Pre-Shared Key (PSK).
PRE-SHARED KEY
The key is entered as a pass-phrase of up to 63 alphanumeric characters in ASCII (American Standard
Code for Information Interchange) format at both ends of the wireless connection. It cannot be shorter than
eight characters, although for proper security it needs to be of ample length and should not be a commonly
known phrase. This phrase is used to generate session keys that are unique for each wireless client.

Example: Wireless Networking technology enables ubiquitous communication
WPA-Enterprise
This option works with a RADIUS Server to authenticate wireless clients. Wireless clients should have
established the necessary credentials before attempting to authenticate to the Server through this Gateway.
Furthermore, it may be necessary to configure the RADIUS Server to allow this Gateway to authenticate
users.

EAP (802.1X)
Authentication Timeout: Amount of time before a client will be required to re-authenticate.
RADIUS Server IP Address: The IP address of the authentication server.
