MOXA AirWorks AWK-1200-AP User’s Manual Web Console Configuration
3-4
WPA Mode: WPA is the older standard; select this option if the clients that will be used with the
Access Point only support the older standard. WPA2 is the newer implementation of the stronger
IEEE 802.11i security standard. With the “WPA2” option, the Access Point tries WPA2 first, but
falls back to WPA if the client only supports WPA. With the “WPA2 Only” option, the Access
Point associates only with clients that also support WPA2 security.
Cipher Type: The encryption algorithm used to secure the data communication. TKIP (Temporal
Key Integrity Protocol) provides per-packet key generation and is based on WEP. AES (Advanced
Encryption Standard) is a very secure block based encryption. With the “TKIP and AES” option,
the Access Point negotiates the cipher type with the client, and uses AES when available.
Group Key Update Interval: The amount of time before the group key used for broadcast and
multicast data is changed.
WPA-Personal
This option uses Wi-Fi Protected Access with a Pre-Shared Key (PSK).
Pre-Shared Key: The key is entered as a pass-phrase of up to 63 alphanumeric characters in
ASCII (American Standard Code for Information Interchange) format at both ends of the wireless
connection. It cannot be shorter than eight characters, although for proper security it needs to be of
ample length and should not be a commonly known phrase. This phrase is used to generate session
keys that are unique for each wireless client.
Example:
Wireless Networking technology enables ubiquitous communication
WPA-Enterprise
This option works with a RADIUS Server to authenticate wireless clients. Wireless clients should
have established the necessary credentials before attempting to authenticate to the Server through
this Gateway. Furthermore, it may be necessary to configure the RADIUS Server to allow this
Gateway to authenticate users.
Authentication Timeout: Amount of time before a client will be required to re-authenticate.
RADIUS Server IP Address: The IP address of the authentication server.
RADIUS Server Port: The port number used to connect to the authentication server.
RADIUS Server Shared Secret: A pass-phrase that must match with the authentication server.
MAC Address Authentication: If this is selected, the user must connect from the same computer
whenever logging into the wireless network.
