[. . . ] The rate of data transmission should be set depending on the speed of your wireless network. You should select from a range of transmission speeds, or you can select Auto to have the wireless router automatically use the fastest possible data rate and enable the AutoFallback feature. Auto-Fallback will negotiate the best possible connection speed between the router and a wireless client. The default setting is "Auto". The Preamble Type defines the length of the CRC (Cyclic Redundancy Check) block for communication between the router and wireless stations. Make sure to select the appropriate preamble type. Note that high network traffic areas should use the "Short Preamble". CRC is a common technique for detecting data transmission errors. If this option is enabled, the router will automatically transmit the network name (SSID) into open air at regular interval. This feature is intended to allow clients to dynamically discover the router. If this option is disabled, the router will hide its SSID. When this is done, the clients cannot directly discover the router and MUST be configure with the SSID for accessing to the router. It is used to protect your network from being accessed easily. When you enable this function, wireless clients will not be able to directly access other wireless clients. It is recommended to enable the protection mechanism. This mechanism can decrease the rate of data collision between 802. 11b and 802. 11g/802. 11n wireless stations. When the Fragmentation Threshold RTS Threshold Beacon Interval Data Rate Preamble Type Broadcast SSID Relay Blocking Protection Aggregation Short GI protection mode is enabled, the throughput of the AP will be a little lower due to many of frame traffic should be transmitted. This function is used to join multiple data packets for transmission as a single unit to increase network efficiency. The 802. 11n draft specifies two guard intervals: 400ns (short) and 800ns (long). Support of the 400ns GI is optional for transmit and receive. Enable this function will increase network efficiency. When you finish, click `Apply Changes'. You'll see the following message displayed on web browser: Press `Continue' to save the settings made and back to web management interface; press `Apply' to save the settings made and restart the router so the settings will take effect after it reboots. QoS The router supports IP QoS feature that can provide different priority to different users or data flows. [. . . ] Check the box to enable router to update time from SNTP server. The IP address or the host name of the SNTP server. You can select from the list or set it manually. When you finish, click `Apply Changes'. You'll see the following message displayed on web browser: Press `Continue' to save the settings made and back to web management interface; press `Apply' to save the settings and restart the router so the settings will take effect after it reboots. Remote Access The Remote Access function can secure remote host access to your router from LAN and WAN interfaces for some services provided by the router. [. . . ]
