Advanced Configuration
v1.0, July 2008
Table 5-1
explains the WLAN1 settings that are displayed in the Advanced WPS Settings
screen. These settings are based on the selections that you made in the Wireless Settings
screen (see
“Manually Configuring Your Wireless Network” in Chapter 2
). In addition,
Table 5-1
explains the modem router’s PIN number.
4.
Under WPS Settings, you can configure the following settings:
•
Disable Router’s PIN
. Only when the modem router’s PIN is enabled, you can configure
the modem router’s wireless settings or add a wireless client through WPS with the
modem router’s PIN number. The PIN function may temporarily be disabled when the
modem router detects suspicious attempts to break into the modem router’s wireless
settings by using the modem router’s PIN through WPS. You can manually enable the PIN
function by deselecting the
Disable Router’s PIN
check box.
•
Keep Existing Wireless Settings
. By default, the
Keep Existing Wireless Settings
check
box is cleared. This allows the modem router to automatically generate the SSID and
WPA/WPA2 security settings when it implements WPS. After WPS is implemented, the
modem router automatically selects this check box so that your SSID and wireless security
settings remain the same if other WPS-enabled devices are added later.
If you configure your wireless router settings and security manually, the
Keep Existing
Wireless Settings
check box will also be enabled. This will allow you to use WPS (Push
'N' Connect) to connect additional WPS capable devices to your wireless network using
the existing settings.

to save your settings.

Troubleshooting
This chapter provides information about troubleshooting your DGN2000 Wireless-N ADSL2+
Modem Router. After each problem description, instructions are provided to help you diagnose
and solve the problem. For the common problems listed, go to the section indicated.
•
Is the router on?
Go to
“Basic Functioning
.”
•
Have I connected the router correctly?
Go to
“Basic Functioning
.”
•
I cannot access the router’s configuration with my browser.
Go to
“Troubleshooting the Web Configuration Interface” on page 6-3
.
•
I have configured the router but I cannot access the Internet.
Go to
“Troubleshooting the ISP Connection” on page 6-4
.
•
I cannot remember the router’s configuration password.
Go to
“Restoring the Default Configuration and Password” on page 6-10
.
•
I want to clear the configuration and start over again.
Go to
“Restoring the Default Configuration and Password” on page 6-10
.
Basic Functioning
After you turn on power to the router, the following sequence of events should occur:
1.
When power is first applied, verify that the Power LED is on.
2.
After approximately 10 seconds, verify the following:
a.
The LAN port LEDs are lit for any local ports that are connected.
b.
The ADSL Link LED is lit.

Troubleshooting
v1.0, July 2008
If the ADSL link 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 is amber.
If any of these conditions does not occur, refer to the appropriate following section.
“Welcome” Page Displays instead of Router Management
Interface
This situation can occur if the CD Setup Wizard does not complete successfully; the unit will stay
in “Wizard Mode”. If the “Welcome” page displays instead of the Router Management interface
when you try to go to the Internet or log into the Router Management interface, you can bypass the
wizard using one of the following methods:
•
Log into the Router Management interface at
http://routerlogin.com/basicsetting.htm
.
•
Perform a factory reset to take the router out of “Wizard Mode” altogether.
Power LED Is Not On
If the Power and other LEDs are off when your router is turned on:
•
Make sure that the power cord is properly connected to your router and that the power supply
adapter is properly connected to a functioning power outlet.
•
Check that you are using the 12 V DC power adapter supplied by NETGEAR for this product.
If the error persists, you have a hardware problem and should contact Technical Support.
Power LED Is Red
When the router is turned on, it performs a power-on self-test. If the Power LED turns red after a
few seconds or at any other time during normal operation, there is a fault within the router. The
Power LED also turns red when you press the Wireless On/Off and WPS buttons on the side panel
of the router simultaneously for 6 seconds, and blinks red 3 times when you release these buttons.
However, in this case, the modem router is working normally.
If the Power LED turns red to indicate a router fault, turn the power off and on to see if the router
recovers.

v1.0, July 2008
If the power LED is still red 1 minute after power up:
•
Turn the power off and on to see if the router recovers.
•
Clear the router’s configuration to factory defaults. This sets the router’s IP address to
192.168.0.1. This procedure is explained in
“Using the Wireless On/Off and WPS Buttons to
Reset the Router” on page 6-10
.
If the error persists, you might have a hardware problem and should contact Technical Support.
LAN or ADSL Port LED Is Not On
If either the LAN LEDs or ADSL Link LED does not light when the Ethernet connection is made,
check the following:
•
Make sure that the Ethernet cable connections are secure at the router and at the hub or
workstation.
•
Make sure that power is turned on to the connected hub or workstation.
•
Be sure you are using the correct cable: when connecting the ADSL port, use the cable that
was supplied with the wireless-N modem router. If the ADSL link LED is still off, this may
mean that there is no ADSL service or the cable connected to the ADSL port is bad.
Window Appears Asking You to Reload Firmware
If a window appears with a message asking you to reload the firmware, this indicates that a
problem has been detected with the current firmware. Please follow the on-screen instructions to
access new firmware and reload the firmware into your router.
Troubleshooting the Web Configuration Interface
If you are unable to access the router’s Web Configuration Interface from a computer on your local
network, check the following:
•
If you are using an Ethernet-connected computer, check the Ethernet connection between the
computer and the router as described in the previous section.
•
Make sure that your computer’s IP address is on the same subnet as the router. 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. Follow the instructions in the online document that you can
access from
“Preparing Your Network” in Appendix B
for information about how to configure
your computer.

•
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 router, and reboot your computer.
•
If your router’s IP address was changed and you do not know the current IP address, clear the
router’s configuration to factory defaults. This sets the router’s IP address to 192.168.0.1. This
procedure is explained in
“Using the Wireless On/Off and WPS Buttons to Reset the Router”
on page 6-10
.
•
Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using
Internet Explorer, click
Refresh
to be sure that 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 you enter this
information.
If the router 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 screen or tab, or your changes are lost.
•
Click the
Refresh
or
Reload
button in the Web browser. The changes might have occurred,
but the Web browser might be caching the old configuration.
Troubleshooting the ISP Connection
If your router is unable to access the Internet, you should check the ADSL connection, then the
WAN TCP/IP connection.
ADSL Link
If your router is unable to access the Internet, you should first determine whether you have an
ADSL link with the service provider. The state of this connection is indicated with the Internet
LED.
