(So-called 40-bit WEP encryption is the same as that offered by the
64 bits
setting. On all
wireless networking products, only 40 bits of a 64-bit key, and 104 bits of a 128-bit key, are input
by the user.)
The default setting is
Disable
. Selecting any other setting enables the WEP key input controls
(for example, the
Passphrase
input box and
Generate
button). WEP itself is not enabled in the
profile until you complete WEP key input.
Selecting
64
,
128
, or
256 bits
also causes input boxes to appear. These boxes show and accept
only “hex” (hexadecimal, that is, base 16) notation. In hex, the numbers 0 through 9 and the
letters A through F are all considered digits (the letters stand for the values we normally refer to
as ten through fifteen). When typing into one of these boxes you must type two hex digits, or your
input is considered incomplete.
If you select
64 bits
, boxes for four WEP keys appear; a
Default Key
control is also displayed.
The
Default Key
control is a drop-down list for indicating which of the four keys is currently in
use on the network. The current key must be selected here, or you will not be able to connect.
If you select
128 bits
, thirteen boxes for a single key will appear.
The
256 bits
setting can only be used on connections to devices in the same product family as
your adapter. Selecting
256 bits
causes 29 input boxes to appear.
A WEP key may be supplied to you in the form of a passphrase, a series of values in hex, or a
plain text string that is not a passphrase.
See the preceding section for instructions on using a passphrase.
If you are given a key or keys in hex, type the values directly into the hex input boxes.
A plain text string must be converted into hexadecimal notation for input. Consult the
conversion charts in appendix A, and then type the correct values directly into the hex
input boxes.
