‰Determine the SSID

In the wireless network, the same SSID (Service Set ID) must be assigned in each wireless device. Only wireless devices that have the same SSID assigned to them can communicate with each other through the wireless network.

In the Infrastructure Mode, the SSID is usually set in the Access Point. Therefore, you must set the same SSID in this equipment to communicate through the wireless network via the Access Point.

In the Ad Hoc Mode, you must assign the same SSID that is assigned to other client computers. To access the devices each other in the Ad Hoc Mode, the same SSID must be assigned to each device.

‰Determine the security mode

This equipment supports the following wireless security modes.

WPA/WPA2

Using the WPA/WPA2, you can restrict the access to the wireless network using the RADIUS server. The WPA/WPA2 is available only when the wireless network is established in the Infrastructure Mode.

There are two protocols for the WPA/WPA2, EAP-TLS or PEAP.

When using the EAP-TLS authentication, you must install user certification file (must be either DER, BASE64, or PKCS#7 encoding format) and CA certification file (must be exported as a private key in PKCS#7 encoding format) in the equipment. This equipment uses the user certification file to authenticate the access rights to the wireless network, and the RADIUS server authenticate this equipment using the user ID and password.

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.

yFor PEAP: Windows Server 2000, Windows Server 2003

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 Infrastructure 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.

When using WPAPSK/WPA2PSK, it is recommended to use a secure password for WPAPSK/WPA2PSK.
