[. . . ] If you do not want to use CTS Protection Mode at all, select Disabled. Frame Burst Mode: This option can trigger your wireless network with higher performance. However, it should depend on the manufacturer of your wireless products, the default is Enabled. Beacon Interval: 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. 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 Router has buffered broadcast or multicast messages 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 messages. Fragmentation Threshold: This value 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 the Fragmentation Threshold too low may result in poor network performance. RTS Threshold: Using this setting can regulate your wireless network if you experience any inconsistent data flow situation, only by minor adjustment of the default value, the default value 2346 is recommended. The RTS/CTS mechanism will not be enabled if your wireless network packet less than RTS threshold value. The Router 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. The RTS Threshold value should keep at its default value of 2346.

User's Guide 20 4. 9 Security The section offers the Block Anonymous Internet Requests feature. Firewall SPI Firewall Protection: Enable this feature to use Stateful Packet Inspection (SPI) for more detailed review of data packets entering your network environment. Block Anonymous Requests: Enable this feature can restrict ICMP request such as "ping" command to probe your network from Internet users. Web Filters: Using the Web Filters feature, you may enable up to four specific filtering methods. Proxy: Use of WAN proxy servers may compromise the Router's security.
