3.1.4 WPA-PSK
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i security specification draft.
Key differences between WPA and WEP are user authentication and improved data
encryption.The encryption mechanisms used for WPA and WPA-PSK are the same. The only
difference between the two is that WPA-PSK uses a simple common password, instead of
user-specific credentials. The common-password approach makes WPA-PSK susceptible to
brute-force password-guessing attacks but it’s still an improvement over WEP as it employs
an easier-to-use, consistent, single, alphanumeric password.
Therefore, if you don’t have an external RADIUS server you should use WPA-PSK (WPA -
Pre-Shared Key) that only requires a single (identical) password entered into each access
point, wireless gateway and wireless client. As long as the passwords match, a client will be
granted access to a WLAN.
3.2 Wizard Setup: General Setup
General Setup contains administrative and system-related information.
The Domain Name entry is what is propagated to the DHCP clients on the LAN. If you leave
this blank, the domain name obtained by DHCP from the ISP is used. While you must enter
the host name (System Name) on each individual computer, the domain name can be assigned
from the ZyAIR via DHCP.
