security. In event of wireless client disconnecting from an AP, a notification is
sent to the AP, which then sends the pre-authentication info to other APs in the
network.
WEP
In the WEP Index and Keys section:
a. In the Authentication field, choose O
Open System
or S
Shared Key
. If you choose
open system, a wireless client doesn't need to provide a shared key in order to
access the wireless network. Any client can associate to the router. If you
choose shared key, a wireless client must provide the correct shared key
(password) in order to access the wireless network.
b. Select the encryption type (6
64-
or 1
128-bit
). The larger size keys provide
stronger encryption, making the key more difficult to crack (for example, 64-bit
WEP has a 40-bit key which is less secure than the 128-bit WEP, which has a
104-bit key).
c. (Optional) In the passphrase field, enter an alphanumeric phrase (longer than
eight characters for optimal security) and click G
Generate Key
to generate four
unique WEP keys in the WEP Key fields below.
d. Select one of the four to use as the shared key that devices must have in order
to use the wireless network. If you did not generate a key in Step C, enter a key
directly into the WEP Key field. The length of the key should be 5 ASCII
characters (or 10 hexadecimal characters) for 64-bit WEP and 13 ASCII
characters (or 26 hexadecimal characters) for 128-bit WEP. Valid hexadecimal
characters are “0” to “9” and “A” to “F”.
STEP 8 Click S
