Important Notice In order to make right use of WPA, please ensure that your current Wireless Adapter’s driver, and Wireless Utility can support it, WPA needs 802.1x authentication (when RADIUS mode is chosen), though the Operating System must also support 802.1x protocol. For Microsoft’s OS family, only Windows XP has incorporated this by default. The rest of the OS must installed 3er party’s client software such as Funk ODySSey. User’s Guide 9 -WPA-Preshared key There are two encryption options for WPA Pre-Shared Key, TKIP and AES. TKIP stands for Temporal Key Integrity Protocol. TKIP utilizes a stronger encryption method and incorporates Message Integrity Code (MIC) to provide protection against hackers. AES stands for Advanced Encryption System, which utilizes a symmetric 128-Bit block data encryption. To use WPA Pre-Shared Key, enter a password in the WPA Shared Key field between 8 and 63 characters long. You may also enter a Group Key Renewal Interval time between 0 and 99,999 seconds. WPA Algorithms Please choose your algorithms method. You can select between TKIP or AES. WPA Shared Key Please input the Pre-Shared Key. The key should be 8 characters or 63 characters in alphanumeric. Group Key Renewal Please input the period of renewal time. The default selection is 300 seconds.
-WPA RADIUS WPA RADIUS uses an external RADIUS server to perform user authentication. To use WPA RADIUS, enter the IP address of the RADIUS server, the RADIUS Port (default is 1812) and the shared secret from the RADIUS server. WPA Algorithms Please choose your algorithms method. You can select between TKIP or AES. Radius Server Address Please input your RADIUS Server IP address. RADIUS Server Port Please input the Authentication port of your RADIUS server. The default port being used is 1812 RADIUS Shared Key The RADIUS server will accept the authentication if both Shared Key matched. Group Key Renewal Please input the period of renewal time.

Please follow the format that it required when an address is input. * Click Apply to save your settings. User’s Guide 16
4.7 Advanced Wireless Authentication Type: Auto: Auto is the default authentication algorithm. It will change its authentication type automatically to fulfill client’s requirement. Open System: Open System authentication is not required to be successful while a client may decline to authenticate with any particular other client. Shared Key: Shared Key is only available if the WEP option is implemented. Shared Key authentication supports authentication of clients as either a member of those who know a shared secret key or a member of those who do not. IEEE 802.11 Shared Key authentication accomplishes this without the need to transmit the secret key in clear. Requiring the use of the WEP privacy mechanism. Transmission Rate: The rate of data transmission should be set depending on the speed of your wireless network. You can select from a range of transmission speeds, or you can select AUTO to have the AP automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed between the AP and a wireless client. The default setting is AUTO. Beacon Interval: The Beacon Interval value indicates the frequency interval of the beacon. Enter a value between 20 and 1000. A beacon is a packet broadcast by the AP to synchronize the wireless network. The default value is 100. User’s Guide 17
RTS Threshold: This value should remain at its default setting of 2346. Should you encounter inconsistent data flow, only minor modifications are recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will not be enabled. The AP sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right to begin transmission. Fragmentation Threshold: This value specifies the maximum size for a packet before data is fragmented into multiple packets. It should remain at its default setting of 2346. If you experience a high packet error rate, you may slightly increase the Fragmentation Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor modifications of this value are recommended. DTIM Interval: This value indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the Access Point has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Access Point Clients hear the beacons and awaken to receive the broadcast and multicast messages. * Click Apply to save your settings. User’s Guide 18
