The parameters include Authentication Type, Fragment Threshold, RTS Threshold, Beacon Interval, preamble Type …… You should not change these parameters unless you know what effect the changes will have on this router. Parameters Description Fragment Threshold Fragment Threshold specifies the maximum size of packet during the fragmentation of data to be transmitted. If you set this value too low, it will result in bad performance. RTS Threshold When the packet size is smaller the RTS threshold, the wireless router will not use the RTS/CTS mechanism to send this packet. Beacon Interval The interval of time that this wireless router broadcast a beacon. Beacon is used to synchronize the wireless network. DTIM Period The DTIM period you specify here indicates how often the clients served by this access point should check for buffered data still on the AP awaiting pickup. Data Rate The “Data Rate” is the rate this access point uses to transmit data packets. The access point will use the highest possible selected transmission rate to transmit the data packets. Preamble Type The “Long Preamble” can provide better wireless LAN compatibility while the “Short Preamble” can provide better wireless LAN performance. Broadcast ESSID If you enable “Broadcast ESSID”, every wireless station located within the coverage of this access point can discover this access point easily. If you are building a public wireless network, enabling this feature is recommended. Disabling “Broadcast ESSID” can provide better security. IAPP If you enable “IAPP”, it will allow wireless station roaming between IAPP enabled access points within the same wireless LAN. CTS Protect It is recommended to enable the protection mechanism. This mechanism can decrease the rate of data collision between 802.11b and 802.11g wireless stations. When the protection mode is enabled, the throughput of the AP will be a little lower due to many of frame traffic should be transmitted. Tx Power You can adjust the wireless transmit power here. By reduce the tx power can let the wireless signal only cover your working area.
31 Turbo Mode By enable the turbo mode can enhance the throughput up to 35Mbps. WMM WMM stands for Wi-Fi Multimedia. It is a standard created to define quality of service (QoS) in Wi-Fi networks.
