Using the Client Encryption Manager

Figure 4-3 Enter WEP keys Screen

Note You can create up to four WEP keys. If a WEP key is set, the Key set box is highlighted, and the

key length is shown in the right column.

Step 3 For the WEP key that you are creating (1, 2, 3, or 4), select a WEP Key Size of 40 or 128 on the right

side of the screen. 128-bit client adapters can use 40- or 128-bit keys, but 40-bit adapters can use only

40-bit keys.

Note Use of 128-bit WEP is subject to U.S. export restrictions.

Step 4 Decide on a WEP key, and enter it in the blank field for the key you are creating. Follow these guidelines

to create a new WEP key:

• Your client adapter’s WEP key must match the WEP key used by the access point or clients with

which you are planning to communicate.

• When you are setting more than one WEP key, the WEP keys must be assigned to the same WEP

key numbers for all devices.

• Home networking WEP keys can be comprised of ASCII text.

• General purpose WEP keys are hexadecimal only and can consist of these hexadecimal characters:

0-9, A-F, and a-f.

• WEP keys must contain the following number of characters:

–

10 characters for 40-bit WEP keys

–

26 characters for 128-bit WEP keys

1 2 ... 53 54 55 56 57 58 59 60 61 62 63 ... 141 142
