[. . . ] If the packet is larger than the specified RTS Threshold size, the router will send RTS frames to a particular receiving station and negotiate the sending of a data frame. The default value is 2346. - 33 - TL-WR841N/TL-WR841ND Wireless N Router Fragmentation Threshold - This value is the maximum size determining whether packets will be fragmented. Setting the Fragmentation Threshold too low may result in poor network performance since excessive packets. DTIM Interval - This value determines 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. The default value is 1, which indicates the DTIM Interval is the same as Beacon Interval. Enable WMM - WMM function can guarantee the packets with high- priority messages being transmitted preferentially. Enable Short GI - This function is recommended for it will increase the data capacity by reducing the guard interval time. Note: If you are not familiar with the setting items in this page, it's strongly recommended to keep the provided default values, otherwise may result in lower wireless network performance. 4. 6. 5 Wireless Statistics Choose menu "WirelessWireless Statistics", you can see the MAC Address, Current Status, Received Packets and Sent Packets for each connected wireless station. Figure 4-17 The router attached wireless stations MAC Address - The connected wireless station's MAC address Current Status - The connected wireless station's running status, one of STA-AUTH / STA-ASSOC / STA-JOINED / WPA / WPA-PSK / WPA2 / WPA2-PSK / AP-UP / AP-DOWN / Disconnected Received Packets - Packets received by the station Sent Packets - Packets sent by the station - 34 - TL-WR841N/TL-WR841ND Wireless N Router You cannot change any of the values on this page.

Click any of them, and you will be able to configure the corresponding function. 4. 7. 1 DHCP Settings Choose menu "DHCPDHCP Settings", you can configure the DHCP Server on the page (shown in Figure 4-19). The router is set up by default as a DHCP (Dynamic Host Configuration Protocol) server, which provides the TCP/IP configuration for all the PC(s) that are connected to the router on the LAN. Figure 4-19 DHCP Settings DHCP Server - Enable or Disable the DHCP server. If you disable the Server, you must have another DHCP server within your network or else you must manually configure the - 35 - TL-WR841N/TL-WR841ND computer. Wireless N Router Start IP Address - This field specifies the first of the addresses in the IP address pool. End IP Address - This field specifies the last of the addresses in the IP address pool. Address Lease Time - The Address Lease Time is the amount of time in which a network user will be allowed connection to the router with their current dynamic IP Address. Default Gateway - (Optional. ) Suggest to input the IP address of the LAN port of the router, default value is 192. 168. 1. 1 Default Domain - (Optional. ) Input the domain name of your network. Primary DNS - (Optional. ) Input the DNS IP address provided by your ISP. Secondary DNS - (Optional. ) Input the IP address of another DNS server if your ISP provides two DNS servers. Note: To use the DHCP server function of the router, you must configure all computers on the LAN as "Obtain an IP Address automatically" mode. 4. 7. 2 DHCP Clients List Choose menu "DHCPDHCP Clients List", you can view the information about the clients attached to the router in the next screen (shown in Figure 4-20). Figure 4-20 DHCP Clients List ID - The index of the DHCP Client Client Name - The name of the DHCP client MAC Address - The MAC address of the DHCP client Assigned IP - The IP address that the router has allocated to the DHCP client. After the dynamic IP address has expired, the user will be automatically assigned a new dynamic IP address. - 36 - TL-WR841N/TL-WR841ND Wireless N Router You cannot change any of the values on this page.
