WEP Encryption
WEP (Wireless Encryption Protocol or Wired Equivalent Privacy) encryption can be enabled for security and privacy.
WEP encrypts the data portion of each frame transmitted from the wireless adapter using one of the predefined keys.
Decryption of the data contained in each packet can only be done if the both the receiver and transmitter have the same
key.
WEP is disabled by default. To enable
WEP
, select the
WEP
option. Configure the Encryption Keys as desired and
click the
Apply
button. The encryption key setup is described below.
WEP can use open or shared keys, or may be configured to allow the clients to use either type of key. Use the
WEP
or
WPA-PSK
click-boxes beside the
WEP Method
field to select the method.
•
Select
None
to allow any wireless station to associate with each other through the access point. Wireless
devices will be able to communicate with all devices on a network unless they require the a Shared key.
•
Select
WEP
to only allow stations using a shared key encryption to associate with each other through the
access point. That is, only devices with the same key are allowed to communicate over a network with devices
that share the same key. Shared key requires additional configuration of the keys to be used. Follow the
instructions below to configure the Shared Keys.
•
Select
WPA-PSK
if you want to allow Wireless clients to specify using a pre-shared key.
Setup Encryption Keys
WEP
Keys may be configured using
Hex
or
ASCII
characters. In addition there are three levels of encryption available,
each level requires a different number of characters. Select
Hex
or
ASCII
from the
Key Type
drop-down menu. Hex or
Hexadecimal digits are defined as the numerical digits 0 – 9 and the letters A – F (upper and lower case are recognized
as the same digit). ASCII characters include numbers and letters but no spaces. An upper case ASCII character is NOT
recognized as the same lower case character, and therefore must be configured exactly as typed for all wireless nodes
using the access point. The length of the key depends on the level of encryption used.
Select the
Key Length
from the drop-down menu beside the
WEP
field. The available key lengths are 64, 128 or 152-
bit encryption. In the spaces provided, type in
Key 1
,
Key 2
,
Key 3
and
Key 4
. The length of the character string used
of the keys depends on the level (Key Length) of encryption selected. Only one key can be active at any one time. The
active key is selected by clicking the radio button for the key you want to use as the first active key.
Click the
Apply
button when you have configured WEP as desired to put the changes into effect.
Note
Keep in mind that encryption, particularly at higher levels (i.e. 128-bit) can adversely affect
thoughput. If your network has very high volume wireless traffic you may want to consider
adding more carrying capacity or decreasing the level of encryption.
