Authentication Type: Select the authentication type under WEP security mode.
The Device must authenticate a wireless client before the client can join the
wireless network. There are three options: Auto, Open System and Shared Key.

Auto: Select to allow the Device automatically choose Open System or
Shared key mode according to the requests of wireless clients.

Open System: At this point, the wireless client host can pass the
authentication and be associated with the wireless devices on the premise of
providing no authentication key; but a correct key must be provided if data
transmission is to be made.

Shared key: At this point, the wireless client host must provide the correct key
to pass the authentication; otherwise, it cannot be associated with the
wireless devices, and cannot perform data transmission.
Key Format: Select the format for entering the WEP keys. The options are Hex
and ASCII.


digits are a set of characters that includes numbers 0 through 9 and letters A
through F (or a through f). Hex WEP keys are case insensitive.

ASCII: Select it to enter the WEP keys in ASCII format. ASCII WEP keys are
case sensitive.
Default Tx Key: Select one of the WEP keys as the default transmitting key to

WEP keys. You should enter a key according to the Key Format and Key Type
selected.
