Enter key prompts for the new passphrase or hexadecimal key.

Key Type

Encryption Key

Hex

Enter the Encryption Key as a hexadecimal value according the following

 

guidelines:

 

Valid Hex alphanumeric characters are 0-9 and A-F.

 

64 bit hex = 5 bytes represented as xx-xx-xx-xx-xx.

 

Example: 01-A3-47-E5-C9

 

128 bit hex = 13 bytes represented as xx-xx-xx-xx-xx-xx-xx-

 

xx-xx-xx-xx-xx-xx.

 

Example: A1-B2-C3-E4-D5-F6-98-74-B7-65-A8-D3-F2

Passphrase

Enter the key as a string. A passphrase is a sentence that is translated into

 

hex by a hashing algorithm.

 

Example: My dog has spots and likes to chase cats.

 

A passphrase of more than 20 characters is recommended. Maximum length

 

is 63 characters, including spaces and punctuation characters.

 

Passphrase input is not the same as ASCII input. The passphrase input is

 

safer because it has up to 63 characters. ASCII input has a maximum of 5

 

(WEP64) or 13 (WEP128) characters and limits the number of key

 

combinations.

Please refer to the other equipment’s manual to determine the passphrase input style recommended.

Set the Encryption type to the minimum required security. The plus sign denotes that the group (broadcast) encryption method is different from the pairwise (unicast) encryption, in this case WEP and TKIP, respectively. For example, CCMP+TKIP => pairwise = CCMP, and group = TKIP.

WPA2/802.11i

The WPA2/802.11i mode complies with the Robust Secure Network specified in the IEEE standard 802.11i. It enables the AES-based strong CCMP encryption.

Enter key prompts for the new passphrase. Maximum length is 63 characters; the recommended minimum is 20 characters.

Fixed or Automatic Data Rate

The XPress DR+W can control the transmission rate. Select 0 to set a fixed data rate, or select 1 to set an automatic data rate. The default setting is 1 (auto).

TX Data rate 0=fixed, 1=auto (1) ? _
