Authentication
Authentication basically means that some form of identification is required.
Authentication therefore protects the network from unwanted access. In the
Security Level box, you can choose between the following types of authentication:
● None (Open System)
There is no authentication. Encryption with a fixed (unchanging) key can be
selected as an option. Based are the key length, you can choose between
WEP and AES. To do this, define a key in the Keys menu. 5 or 13 ASCII or 10
or 26 hexadecimal characters specify a weak WEP key (40/104 bits). 16 ASCII
or 32 hexadecimal characters, on the other hand, define a strong AES key (128
bits). Then select Encryption in the Basic WLAN menu.
● Low (Shared Key)
In Shared Key authentication, a fixed key is stored on the client and access
point. This is then used for authentication and encryption. In this case, you will
have to store a WEP or AES key after selecting Low (Shared Key).
