Diagnostics

You can perform various diagnostics. For normal operation, these tests are not required.

To perform diagnostic tests:
1. Select ADVANCED > Administration > Diagnostics to display the following screen:
2. Perform the following diagnostics as needed:
• Ping an IP address or Host Name. Use this test to send a ping packet request to the
specified IP address or host name. This test is often used to test a connection. If the
request times out (in other words, no reply is received), this result usually means that
the destination is unreachable. Note, however, that some network devices can be
configured not to respond to a ping.
• Perform a DNS Lookup. A DNS (Domain Name Server) converts the Internet name
(for example, www.netgear.com) to an IP address. If you need the IP address of a
web, FTP, mail, or other server on the Internet, do a DNS lookup to find the IP
address.
• Display the Routing Table. This operation displays the internal routing table.
