b.
To allow access from a range of IP addresses on the Internet, select IP address range.
Enter a beginning and ending IP address to define the allowed range.
c.
To allow access from a single IP address on the Internet, select Only this PC.
Enter the IP address that will be allowed access.
3.
Specify the Port Number that will be used for accessing the management interface.
web browser access normally uses the standard HTTP service port 80. For greater security,
you can change the remote management web interface to a custom port by entering that
number in the box provided. Choose a number between 1024 and 65535, but do not use the
number of any common service port. The default is 8080, which is a common alternate for
HTTP.
4.
Click Apply to have your changes take effect.
Note:
When accessing your router from the Internet, you will type your router's WAN IP address
into your browser's Address (in IE) or Location (in Netscape) box, followed by a colon (:) and the
custom port number. For example, if your external address is 134.177.0.123 and you use port
number 8080, you must enter
in your browser.
Using Universal Plug and Play (UPnP)
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers,
access the network and connect to other devices as needed. UPnP devices can
automatically discover the services from other registered UPnP devices on the network.

Turn UPnP On:
UPnP can be enabled or disabled for automatic device configuration. The default
setting for UPnP is enabled. If disabled, the router will not allow any device to automatically
control the resources, such as port forwarding (mapping), of the router.
Advertisement Period
: The Advertisement Period is how often the router will broadcast its UPnP
information. This value can range from 1 to 1440 minutes. The default period is 30 minutes.
Shorter durations will ensure that control points have current device status at the expense of
additional network traffic. Longer durations may compromise the freshness of the device status but
can significantly reduce network traffic.
Advertisement Time To Live
: The time to live for the advertisement is measured in hops (steps)
for each UPnP packet sent. The time to live hop count is the number of steps a broadcast packet is
allowed to propagate for each UPnP advertisement before it disappears. The number of hops can
range from 1 to 255. The default value for the advertisement time to live is 4 hops, which should
be fine for most home networks. If you notice that some devices are not being updated or reached
correctly, then it may be necessary to increase this value a little.
UPnP Portmap Table
: The UPnP Portmap Table displays the IP address of each UPnP device that
is currently accessing the router and which ports (Internal and External) that device has opened.
The UPnP Portmap Table also displays what type of port is opened and if that port is still active for
each IP address.

Troubleshooting
This chapter gives information about troubleshooting your 108 Mbps Wireless Firewall Router
WGT624 v2. After each problem description, instructions are provided to help you diagnose and
solve the problem.
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 that:
a.
The Local port LEDs are lit for any local ports that are connected.
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.
b.
The Wireless port LED is lit.
c.
The Internet port 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 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.

Troubleshooting
M-10153-01
Check that you are using the 12 V DC 800mA power adapter supplied by NETGEAR for this
product.
If the error persists, you have a hardware problem and should contact technical support.
LEDs Never Turn Off
When the router is turned on, the LEDs turns on for about 10 seconds and then turn off. If all the
LEDs stay on, there is a fault within the router.
If all LEDs are still on one minute after power up:
Cycle the power to see if the router recovers.
Clear the router’s configuration to factory defaults. This will set the router’s IP address to
192.168.0.1. This procedure is explained in
“Restoring the Default Configuration and
Password” on page 8-7
.
If the error persists, you might have a hardware problem and should contact technical support.
Local or Internet Port LEDs Not On
If either the LAN LEDs or WAN LED do 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 router’s WAN 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 router’s web Configuration interface from a PC on your local
network, check the following:
Check the Ethernet connection between the PC and the router as described in the previous
section.
Make sure your PC’s IP address is on the same subnet as the router. If you are using the
recommended addressing scheme, your PC’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-6
or
“Verifying TCP/IP
Properties for Macintosh Computers” on page C-17
to find your PC’s IP address. Follow the
instructions in
Appendix C
to configure your PC.
Note:
If your PC’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 PC to the router and reboot your PC.
If your router’s IP address has been changed and you don’t know the current IP address, clear
the router’s configuration to factory defaults. This will set the router’s IP address to
192.168.0.1. This procedure is explained in
“Restoring the Default Configuration and
Password” 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 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 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.
