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 Power LED is on.
2.
Verify that the Test LED lights within a few seconds, indicating that the self-test procedure is
running.
3.
After approximately 10 seconds, verify that:

a.
The Test LED is not lit.
b.
The Local port Link LEDs are lit for any local ports that are connected.
c.
The Internet Link port LED is lit.
If a port’s Link LED is lit, a link has been established to the connected device. If a port is
connected to a 100 Mbps device, verify that the port’s 100 LED is lit.
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.
•
Check that you are using the 12VDC power adapter supplied by NETGEAR for this product.
If the error persists, you have a hardware problem and should contact technical support.
Test LED Never Turns On or Test LED Stays On
When the firewall is turned on, the Test LED turns on for about 10 seconds and then turns off. If
the Test LED does not turn on, or if it stays on, there is a fault within the firewall.
If you experience problems with the Test LED:
•
Cycle the power to see if the firewall recovers and the LED blinks for the correct amount of
time.
If all LEDs including the Test LED are still on one minute after power up:
•
Cycle the power to see if the firewall recovers.
•
Clear the firewall’s configuration to factory defaults. This will set the firewall’s IP address to
192.168.0.1. This procedure is explained in
“How to Use the Default Reset Button” on page
8-7
.
If the error persists, you might have a hardware problem and should contact technical support.

Local or Internet Port Link LEDs Not On
If either the Local or Internet Port Link LEDs do not light when the Ethernet connection is made,
check the following:
•
Make sure that the Ethernet cable connections are secure at the firewall and at the hub or
computer.
•
Make sure that power is turned on to the connected hub or computer.
•
Be sure you are using the correct cable:
—
When connecting the firewall’s Internet port to a cable or DSL modem, use the cable that
was supplied with the cable or DSL modem. This cable could be a standard
straight-through Ethernet cable or an Ethernet crossover cable.
Troubleshooting the Web Configuration Interface
If you are unable to access the firewall’s Web Configuration interface from a computer on your
local network, check the following:
•
Check the Ethernet connection between the computer and the firewall as described in the
previous section.
•
Make sure your computer’s IP address is on the same subnet as the firewall. If you are using
the recommended addressing scheme, your computer’s address should be in the range of
192.168.0.2 to 192.168.0.254. Refer to
“Verifying TCP/IP Properties” on page C-7
or
“Configuring the Macintosh for TCP/IP Networking” on page C-9
to find your computer’s IP
address. Follow the instructions in
Appendix C
to configure your computer.
Note:
If your computer’s IP address is shown as 169.254.x.x:
Recent versions of Windows and MacOS will generate and assign an IP address if the
computer cannot reach a DHCP server. These auto-generated addresses are in the range of
169.254.x.x. If your IP address is in this range, check the connection from the computer to the
firewall and reboot your computer.
•
If your firewall’s IP address has been changed and you don’t know the current IP address,
clear the firewall’s configuration to factory defaults. This will set the firewall’s IP address to
192.168.0.1. This procedure is explained in
“How to Use the Default Reset Button” on page
8-7
.
•
Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet
Explorer, click Refresh to be sure the Java applet is loaded.

•
Try quitting the browser and launching it again.
•
Make sure you are using the correct login information. The factory default login name is
admin
and the password is
password
. Make sure that CAPS LOCK is off when entering this
information.
If the firewall does not save changes you have made in the Web configuration interface, check the
following:
•
When entering configuration settings, be sure to click the Apply button before moving to
another menu or tab, or your changes are lost.
•
Click the Refresh or Reload button in the Web browser. The changes may have occurred, but
the Web browser may be caching the old configuration.
Troubleshooting the ISP Connection
If your firewall is unable to access the Internet, you should first determine whether the firewall is
able to obtain a WAN IP address from the ISP. Unless you have been assigned a static IP address,
your firewall must request an IP address from the ISP. You can determine whether the request was
successful using the Web configuration manager.
To check the WAN IP address:
1.
Launch your browser and select an external site such as
www.netgear.com.
2.
Access the main menu of the firewall’s configuration at
.
3.
Under the Maintenance heading, select Router Status.
4.
Check that an IP address is shown for the WAN Port.
If 0.0.0.0 is shown, your firewall has not obtained an IP address from your ISP.
If your firewall is unable to obtain an IP address from the ISP, you may need to force your cable or
DSL modem to recognize your new firewall by performing the following procedure:
1.
Turn off power to the cable or DSL modem.
2.
Turn off power to your firewall.
3.
Wait five minutes and reapply power to the cable or DSL modem.
4.
When the modem’s LEDs indicate that it has reacquired sync with the ISP, reapply power to
your firewall.
