HITRON CGNV2 USER’S GUIDE
WIRELESS
Authentication Select the authentication mode that you want to use:

Select Open System to allow wireless clients to
authenticate (identify themselves) to the CGNV2
before presenting their security credentials (WEP
keys).

Select Shared Key to use the WEP key in the
authentication process. When a client wants to
associate, the CGNV2 sends an unencrypted
challenge message. The client must use the WEP
key to encrypt the challenge message and return it to
the CGNV2, which then decrypts the message and
compares the result with its original message.
Open System authentication is the more secure of the
two authentication types, since while the Shared Key
system appears more robust, it is possible to derive
secure data by capturing the challenge messages.

Select Automatic to have the CGNV2 choose the
authentication method.
WPA_Personal
NOTE: These fields are only configurable when you select WPA-Personal from the
Security Mode list.
WPA Mode Select the type of WPA security that you want to use:

clients operating in either mode to connect to the
CGNV2.


Select TKIP to use the Temporal Key Integrity
Protocol.

Standard.

Select TKIP and AES to allow clients using either
encryption type to connect to the CGNV2.
