MAC Address - The physical address of the Router, as seen from the LAN. The value can't be changed. IP Address - Enter the IP address of your Router or reset it in dotted-decimal notation (factory default: 192.168.1.1). Subnet Mask - An address code that determines the size of the network. Normally use 255.255.255.0 as the subnet mask. Note: a. b. If you change the IP Address of LAN, you must use the new IP Address to log in the Router. If the new LAN IP Address you set is not in the same subnet, the IP Address pool of the DHCP server will change accordingly at the same timewhile the Virtual Server and DMZ Host will not take effect until they are re-configured.

4.5.2 WAN

Choose menu Network WAN, you can configure the IP parameters of the WAN on the screen below. 1. If your ISP provides the DHCP service, please choose Dynamic IP type, and the Router will automatically get IP parameters from your ISP. You can see the page as follows (Figure 4-6):

Otherwise, the DNS servers will be assigned dynamically from your ISP. Note: If you find error when you go to a website after entering the DNS addresses, it is likely that your DNS servers are set up improperly. You should contact your ISP to get DNS server addresses. Get IP with Unicast DHCP - A few ISPs' DHCP servers do not support the broadcast applications. If you cannot get the IP Address normally, you can choose this option. (It is rarely required.) Click the Save button to save your settings. 2. If your ISP provides a static or fixed IP Address, Subnet Mask, Gateway and DNS setting, select Static IP.

4.16.2 Diagnostic

Choose menu System Tools Diagnostic, you can transact Ping or Traceroute function to check connectivity of your network in the following screen.

Figure 4-72

Diagnostic Tools
Diagnostic Tool - Check the radio button to select one diagnostic too. Ping - This diagnostic tool troubleshoots connectivity, reachability, and name resolution to a given host or gateway. Traceroute - This diagnostic tool tests the performance of a connection. Note: You can use ping/traceroute to test both numeric IP address or domain name. If pinging/tracerouting the IP address is successful, but pinging/tracerouting the domain name is not, you might have a name resolution problem. In this case, ensure that the domain name you are specifying can be resolved by using Domain Name System (DNS) queries. IP Address/Domain Name - Type the destination IP address (such as 202.108.22.5) or Domain name (such as www.tp-link.com).

Appendix A: FAQ
1. How do I configure the Router to access Internet by ADSL users? 1) 2) First, configure the ADSL Modem configured in RFC1483 bridge model. Connect the Ethernet cable from your ADSL Modem to the WAN port on the Router. The telephone cord plugs into the Line port of the ADSL Modem. 3) Log in to the Router, click the Network menu on the left of your browser, and click "WAN" submenu. On the WAN page, select PPPoE for WAN Connection Type. Type user name in the User Name field and password in the Password field, finish by clicking Connect.

Figure A-1 4)

PPPoE Connection Type
If your ADSL lease is in pay-according-time mode, select Connect on Demand or Connect Manually for Internet connection mode. Type an appropriate number for Max Idle Time to avoid wasting paid time. Otherwise, you can select Auto-connecting for Internet connection mode.
