Encryption
If an additional measure of security is desired on the wireless network, WEP
(Wired Equivalent Privacy) encryption can be enabled. WEP encrypts each
frame transmitted from the wireless adapter using one of the keys entered in
the WEP Privacy field. The Access Point or wireless adapter will accept only
encrypted frames that it can decrypt correctly. Decrypting can take place only
if the receiver has the correct key used by the transmitter.
Active Key: Active Key ID determines which Key (Key 1 to Key 4) encrypts
and decrypts the transmissions received by the Access Point.
WEP Type: The 64 or 128-bit Wired Equivalent Privacy Algorithm. Use this
to enable 64-bit or 128-bit encryption. WEP is disabled by default.
Authentication Type: Choose Open System, Shared Key or Both.
Open System: With this setting any station in the Wireless LAN can
associate with an Access Point to receive and to transmit data.
