GN-1041 Operator’s Manual — Before Setting Up Wireless Network
When using the PEAP, you must install the CA certification file (must be either DER, 
BASE64, or PKCS#7 encoding format) in the equipment.  This equipment uses the user 
name and password to authenticate the access rights to the wireless network, and the 
RADIUS server authenticate this equipment using the CA certification file.
NOTE:
This equipment supports following RADIUS server.

For EAP-TLS: Windows 2000 Server, Windows 2003 Server, Funk Odyssey Server

For PEAP: Windows 2000 Server, Windows 2003 Server
WPAPSK/WPA2PSK
The WPAPSK/WPA2PSK is an authentication method using the PSK (Pre-Shared Key) 
between the Access Point and other wireless devices.  The WPAPSK/WPA2PSK 
authentication is available only when the wireless network is established in the Infra-
structure Mode.
To access the wireless network using the WPAPSK/WPA2PSK authentication, the 
same PSK Path Phrase must be assigned in both the Access Point and other wireless 
devices.  If the PSKs are same between the Access Point and other wireless devices, 
the Access Point allows them to access the wireless network through the Access Point.
The WPAPSK/WPA2PSK has stronger security than WEP because the data encryption 
is improved over WEP.  This equipment supports TKIP and AES(CCMP) encryption for 
the WPAPSK/WPA2PSK authentication.
The TKIP provides a different key for per packet with a message integrity check.  This 
key will be changed for every fixed interval.
The AES is the next-generation cryptography algorithm that the U.S. government 
improves to replace the DES and 3DES.
This authentication method is suitable for a small wireless network and easy to add the 
security because the authentication server is not required unlike the WPA/WPA2/802.1x 
authentication.
NOTE:
When using WPAPSK/WPA2PSK, it is recommended to use a secure password for 
WPAPSK/WPA2PSK.
WEP
The WEP is a data encryption method using the WEP key between the Access Point 
and other wireless devices.  Compared with WPA/WPA2/802.1x and WPAPSK/
WPA2PSK, the WEP is less security.  If the wireless network is configured in the Infra-
structure Mode and the Access Point supports WPA/WPA2/802.1x or WPAPSK/
WPA2PSK, it is recommended to use WPA/WPA2/802.1x or WPAPSK/WPA2PSK 
rather than WEP.
The WEP authentication is available for both the Infrastructure Mode and Ad Hoc 
Mode.
