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.

•
“Basic Functions” on page 7-1
•
“Troubleshooting the Web Configuration Interface” on page 7-2
•
“Troubleshooting the ISP Connection” on page 7-4
•
“Troubleshooting a TCP/IP Network Using a Ping Utility” on page 7-5

Basic Functions
After you turn on power to the firewall, the following sequence of events should occur:
1.
When power is first applied, verify that the PWR LED is on.
2.
After approximately 2 minutes, verify that:
a.
The TEST LED is not lit.
b.
The LAN port LEDs are lit for any local ports that are connected.
c.
The Internet port LED is lit.
If a port’s LED is lit, a link has been established to the connected device. If a LAN port is
connected to a 100 Mbps device, verify that the port’s LED is green. If the port is 10 Mbps, the
LED will be amber.
If any of these conditions does not occur, refer to the appropriate following section.
Power LED Not On
If the Power and other LEDs are off when your firewall is turned on:
•
Make sure that the power cord is properly connected to your firewall and that the power
supply adapter is properly connected to a functioning power outlet.
