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. 192. 168. 1. 100 is the default start address. End IP Address - This field specifies the last of the addresses in the IP address pool. 192. 168. 1. 199 is the default end address. 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. The user will be "leased" this dynamic IP Address. The range of the time is 1 ~ 2880 minutes. 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. Lease Time - The time of the DHCP client leased. 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. To update this page and to show the current attached devices, click the Refresh button. 4. 7. 3 Address Reservation Choose menu "DHCPAddress Reservation", you can view and add a reserved addresses for clients via the next screen (shown in Figure 4-21). When you specify a reserved IP address for a PC on the LAN, that PC will always receive the same IP address each time when it accesses the DHCP server. Reserved IP addresses should be assigned to the servers that require permanent IP settings. Figure 4-21 Address Reservation MAC Address - The MAC address of the PC of which you want to reserve IP address. Assigned IP Address - The IP address of the router reserved. Status - The status of this entry either Enabled or Disabled. (Pop-up Figure 4-22) Enter the MAC address (in XX-XX-XX-XX-XX-XX format. ) and IP address in dotted-decimal notation of the computer you wish to add. Click the Save button when finished.
