D-Link DWL-650 user manual Passphrase, Manual Entry Key 1 Key, Default Tx Key

CONFIGURATION UTILITY

The Access Point or wireless adapter will accept only encrypted frames that it can decrypt correctly. This will only happen if the receiver has the "WEP Key" used by the transmitter.

When WEP Encryption is enabled, there are two options: 64-bit and 128- bit.

NOTE: 64 bit WEP is the same as 40 bit WEP!

The lower level of WEP encryption uses a 40 bit (10 character) “secret key” (set by the user), and a 24 bit “Initialization Vector” (not under user control).

The panel allows the entry of four keys for 64-bit encryption and one set for 128-bit key encryption. Each key must consist of hex digits, which means that only digits 0-9 and letters A-F are valid entries.

The Configuration Utility will not apply keys that are not entered cor- rectly.

Passphrase

Alternatively, a "Passphrase" can be entered which is used as a "seed" to randomly generate the four keys. Using the "Passphrase" saves considerable time since the same keys must be entered into each node on the wireless network.

Manual Entry:

Key 1 - Key 4

These four fields can be used to manually enter the encryption keys This may be necessary if you wish this node to match keys in a diffe ent vendor's product. These fields also display the keys when they are generated using a Pass-phrase.

Default Tx Key

The button updates the wireless adapter with the four keys entered Key 1 through Key 4. Once the "Apply" button is selected, the keys are updated for the wireless adapter. Please note that the "Default T Key" is not an available option when 128 bit encryption is selected.
