WEP Authentication Type
WEP (Wired Equivalent Privacy) is a kind of standard to encrypt the data
frame.
• Open system: No encryption for network communication. You can
neglect the key setting on the right side.
• WEP Share Key: Both communication devices use the same key as
encryption.
• Automatic: Detect the WEP situation of the access point automatically.
ADAM-4570W/4571W will use the current key for encryption. If
ADAM-4570W/4571W’s key does not coincide with the access point’s
key, the user should reset the same key and reboot to connect.
Encryption
If the system needs WEP encryption, the user has to set the key type.
There are two kinds of encryption keys: 64 bits and 128 bits. For an open
system, the encryption function is disabled.
