All items in this category are described in detail below. Figure 3-5-2. Wireless – Security Network Authentication: Select the network Authentication method. 802.1X and WPA require to set valid RADIUS parameters. WPA-PSK requires a valid WPA Pre-Shared Key to be set. 802.1X: As the IEEE standard for access control for wireless and wired LANs, 802.1x provides a means of authentication and authorizing devices to attach to a LAN port. This standard defines the Extensible Authentication Protocol (EAP), which uses a central authentication server to authenticate each user on the network.

DIRECT ACCESS to GW5051 Page 28 WPA / WPA2: The Wi-Fi Alliance put together WPA / WPA2 as a data encryption method for 802.11 wireless LANs. WPA is an industry-supported, pre-standard version of 802.11i utilizing the Temporal Key Integrity Protocol (TKIP), which fixes the problems of WEP, including using dynamic keys. WPA / WPA2 Pre-Shared Key: Set the WPA / WPA2 Pre-Shared Key (PSK). WPA / WPA2 Group Rekey Interval: Set the WPA / WPA2 Group Rekey Interval in seconds. Leave blank or set to zero to disable periodic re-keying. Radius Server: Set the IP address of the RADIUS server to use for authentication and dynamic key derivation. RADIUS Server: It is responsible for receiving user connection requests, authenticating the user, and then returning all of the configuration information necessary for the client to deliver the server to the user. Radius Port: Sets the UDP port number of the RADIUS server. The port number is usually 1812 or 1645 and depends on the server. Radius Key: Set the shared secret for the RADIUS connection. Data Encryption (WEP): Selecting Off disables WEP data encryption. Selecting WEP enables WEP data encryption and requires that a valid network key be set and selected unless 802.1X is enabled. WEP: It stands for Wired Equivalent Privacy, is a protocol for wireless LANs or local area networks. This WEP is defined in the 802.11 Standard. WEP is designed so security levels are maintained at the same level as the wired LAN. WEP’s aim is to provide security by encrypting data over radio waves. WEP protects data as it’s transmitted from one end point to another. WEP is used at two lowest layers, the data link and physical layer. WEP is designed to make up for the inherent security in wireless transmission as compared to wired transmission. Shared Key Authentication: Set whether shared key authentication is required to associate. A valid network key must be set and selected if required. In the end, click “Apply/Save” to effect the configuration.

DIRECT ACCESS to GW5051 Page 29 3.11.3. MAC Filter Click the third category “MAC Filter” to enter into the related configuration of the MAC address. Figure 3-5-3.

DIRECT ACCESS to GW5051 Page 31 Figure 3-5-5. Wireless – Advanced Channel: Select the appropriate channel from the list provided to correspond with your network settings. All devices in your wireless network must use the same channel in order to function correctly. Rate: The default setting is “Auto”. The range is from 1 to 54Mbps. The rate of data transmission should be set depending on the speed of your wireless network. You can select from one transmission speed, or keep the default setting, “Auto”, to have the IAD automatically use the fastest possible data rate. Multicast Rate: The default setting is 54Mbps. The range is from 1 to 54Mbps. The rate of data transmission should be set depending on the speed of your wireless network. You can select from one transmission speed, or keep the default setting, to have the IAD automatically use the fastest data rate for multicast packets. Basic Rate: Select the basic rate that wireless clients must support. Fragmentation Threshold: This value should remain at its default setting of 2346. The range is 256~2346 bytes. It specifies the maximum size for a packet before data is fragmented into multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation Threshold. Setting this value too low may result in poor network performance. Only minor modifications of this value are recommended.

DIRECT ACCESS to GW5051 Page 32 RTS Threshold: This value should remain at its default setting of 2347. The range is 0~2347 bytes. Should you encounter inconsistent data flow, only minor modifications are recommended. If a network packet is smaller than the packet RTS threshold size, the RTS / CTS mechanism will not be enabled. The IAD 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. DTIM Interval: The default value is 3. This value, between 1 and 255 milliseconds, 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 router has buffered broadcast or multicast for associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast message. Beacon Interval: The default value is 100. Its range is between 1 and 65535 milliseconds. The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the router to synchronize the wireless network. XPress™ Technology: Select to enable / disable this proprietary mode. 54g™ Mode: Select the mode to 54g Auto for the widest compatibility. Select the mode to 54g Performance for the fastest performance among 54g certified equipment. Set the mode to 54g LRS if you are experiencing difficulty with legacy 802.11b equipment. 54g protection: In Auto mode, the IAD will use RTS / CTS to improve 802.11g performance in mixed 802.11g/802.11b networks. Turn protection off to maximize 802.11g throughput under most conditions. WMM (Wi-Fi Multimedia): Select to enable / disable the support. 3.11.6.
