Item Description
Ping or Trace an IP
address Ping – Used to send a ping packet request to a specified IP address—most often, to
test a connection. If the request times out (no reply is received), it usually means that
the destination is unreachable. However, some network devices can be configured
not to respond to a ping. The ping results will be displayed in a new screen; click
“Back” on the Windows menu bar to return to the Diagnostics screen.
Traceroute (often called Trace Route) – Lists all Routers between the source (this
device) and the destination IP address. The Trace Route results will be displayed in a
new screen; click “Back” on the Windows menu bar to return to the Diagnostics
screen.
Perform a DNS
Lookup A DNS (Domain Name Server) converts the Internet name (e.g. www.netgear.com) to
an IP address. If you need the IP address of a Web, FTP, Mail or other Server on the
Internet, you can do a DNS lookup to find the IP address.
Display the Routing
Table This operation will display the internal routing table. This information is used, most
often, by Technical Support.
Reboot the Router Used to perform a remote reboot (restart). You can use this if the Router seems to
have become unstable or is not operating normally.
Note : Rebooting will break any existing connections either to the Router (such as this
one) or through the Router (for example, LAN users accessing the Internet).
However, connections to the Internet will automatically be re-established when
possible.
Packet Trace Packet Trace selects the interface and starts the packet capture on that interface.
