802.1x authentication for wireless LANs provides centralized, server-based
athentication of end users.
1) A client sends a “start” message to an access point, which requests the identity
of the client.
2) The client replies with a response packet containing an identity, and the access
point forwards the packet to an authentication server.
3) The authentication server sends an “accept” packet to the access point.
4) The access point places the client port in authorized state, and traffic is allowed
to proceed.
Note: It is necessary that the Radius page have to be configured if the option
“802.1x” is seleted.
If the 802.1x – Dynamic WEP option is selected, and then you only have to choose
which WEP type you want. Due to the key value will be generated by system.

64 (40) Bits, 128 (104) Bits or 152 (128) Bits
There are three levels of encryption 64 bits, 128 bits and 152 bits. The 64 bits
encryption is referenced as a lower level encryption. The 152 bits encryption is
referenced as a higher level encryption.
The 64 bits WEP encryption use 40 bits as a secret key, which can controlled by
user, and 24 bits as the initialize vector, which user can not control. These two
portions plus together is 64 bits encryption. Some other vendor’s product might refer
as 40 bits encryption. It is the same thing.
The 128 bits WEP encryption use 104 bits as a secret key, which can controlled by
user, and 24 bits as the initialize vector, which user can not control. These two
portions plus together is 128 bits encryption. Some other vendor’s product might
refer as 104 bits encryption. It is the same thing.
The 152 bits WEP encryption use 128 bits as a secret key, which can controlled by
user, and 24 bits as the initialize vector, which user can not control. The 152 bits
WEP encryption spawns a KEY ID containing 32 HEX digits.
