System Management > Diagnostic

The Router has two built-in tools, DNS Name Lookup and Ping, which are used for troubleshooting network problems.

The Internet has a service called the Domain Name Service (DNS), which allows users to enter an easily remembered host name, such as www.linksys.com, instead of numerical TCP/IP addresses to access Internet resources. The DNS Name Lookup tool will return the numericalTCP/IP address of a host name.

The ping test bounces a packet off a machine on the Internet back to the sender. This test shows if the Router is able to contact the remote host. If users on the LAN are having problems accessing services on the Internet, try pinging the DNS server or other machine at the ISP’s location. If this test is successful, try pinging devices outside the ISP. This will show if the problem lies with the ISP’s connection.

Diagnostic

DNS Name Lookup/Ping  Select which tool you want to use, DNS Name Lookup or Ping. Then proceed to the appropriate instructions.

DNS Name Lookup

Before using this tool, make sure the IP address of the DNS server is entered on the Setup > Network screen; otherwise, this tool will not work.

System Management > Diagnostic > DNS Name Lookup

Look up the name  Enter the host name, and click Go. (Do not add the prefix http:// or else you will get an error message.) The Router will then query the DNS server and display the results.

Name  The host name is displayed. Address  The URL of the host is displayed.

Ping

Before using this tool make sure you know the device or host’s IP address. If you do not know it, use the Router’s DNS Name Lookup tool to find the IP address.
