Description
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 the wireless
gateway and wireless client. As long as the passwords
match, a client will be granted access to the wireless
LAN. Select to Enable or Disable.
Advanced protocol, certified through Wi-Fi Alliance's
WPA2 program, implements the mandatory elements of
802.11i. In particular, it introduces a new AES-based
algorithm, CCMP, that is considered fully secure. Select to
Enable or Disable.
If you don't have an external RADIUS server you should
use WPA2-PSK (WPA Pre-Shared Key) that only requires
a single (identical) password entered into wireless
gateway and wireless client. As long as the passwords
match, a client will be granted access to the wireless
LAN. Select to Enable or Disable.
Switch to enable or disable WPA/WPA2 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. If WPA2-PSK is enabled, enter
a preshared key. Refer to
the shared key. Connecting clients will need to enter this
shared key to access the network.
Input the IP address of RADIUS server, if used.
Enter a RADIUS port number when WPA or 802.1x
network authentication is selected.
Enter the RADIUS Key when WPA or 802.1x network
authentication is selected.
Allows the wireless router to generate the best possible
random group key and update all the key-management
capable stations periodically.
Wireless router (if using WPA-PSK key management) or
RADIUS server (if using WPA key management) sends a
new group key out to all clients. The re-keying process is
the WPA equivalent of automatically changing the WEP
key for a wireless access point and all stations in the
WLAN on a periodic basis. Setting of the WPA Group Key
Update Timer is also supported in WPA-PSK mode.
If you don't have WPA(2)-aware wireless clients, then use
WEP key encrypting. A higher bit key offers better security.
WEP encryption scrambles the data transmitted between the
wireless stations and the wireless router to keep network
communications private. It encrypts unicast and multicast
communications in a network. Both the wireless stations and
the wireless router must use the same WEP key. Data
Encryption can be set to WEP 128-bit, 64-bit, or Disable.
