Setting Encryption

Before configuring encryption on the AP, determine the encryption parameters as follows:

1. Create up to four keys, where the keys can be:

— 5 printable characters or 10 hexadecimal digits if the RoamAbout PC Card

supports 40-bit WEP encryption.

— 13 printable characters or 26 hexadecimal digits if the RoamAbout PC Card

supports 128-bit encryption.

You must create at least one key. The printable character keys are case-sensitive. A

hexadecimal digit key must start with 0x, which is not counted in the number of digits.

For example, 0xABCDEF0123 is a valid 40-bit encryption hexadecimal key (10

hexadecimal digits).

2. Determine the positions for each key. There are four positions, Key 1, Key 2, Key 3,

and Key 4. The position of each key is important since all the wireless devices must

enter the same key in the same position to decipher encrypted data.

3. Determine which key to use as the transmit key.

4. Determine whether to allow or disallow the AP from communicating with clients that

do not use encryption.

For more information, refer to Wired Equivalent Privacy (WEP) Encryption on page

2-15.

Using the AP Manager

To configure encryption using the AP Manager, perform the following:

1. In the main window, select the AP in the Managed List.

2. Click on the Encryption button.

3. If this is a RoamAbout R2, select the slot to configure.

4. Enter the encryption parameters as described previously. The Deny Non-encrypted

Data setting, when checked, prevents the AP from communicating with clients that do

not use encryption.

5. Click on OK to accept the parameters.

6. If prompted, click on OK to reset the AP. Allow approximately one minute for the AP

to reset and complete its self-test. You do not need to reset the AP if you only add,

delete, or modify keys, or change the transmit key.
