P-873HNUP-51B Support Notes
What is the difference between Open System and Shared Key of Authentication
Type?
Open System:
The default authentication service that simply announces the desire to associate with
another station or access point. A station can authenticate with any other station or
access point using open system authentication if the receiving station designates
open system authentication.
Share Key:
The optional authentication that involves a more rigorous exchange of frames,
ensuring that the requesting station is authentic. For a station to use shared key
authentication, it must implement WEP.
What is AAA?
AAA is the acronym for Authentication, Authorization, and Accounting and refers to
the idea of managing subscribers by controlling their access to the network, verifying
that they are who they say they are (via login name and password or MAC address)
and accounting for their network usage.
What is WPA-PSK?
WPA-PSK (Wi-Fi Protected Access Pre-Shared Key) can be used if user do not have a
Radius server but still want to benefit from it. Because WPA-PSK only requires a
single password to be entered on wireless AP/gateway and wireless client. As long
as the passwords match, a client will be granted access to the WLAN.
