Enabling Universal Plug and Play (UPnP)
UPnP (Universal Plug and Play) allows for automatic discovery of devices that can communicate
with this router. This feature should be used with caution as it breaches firewall security. Select
Security > UPnP to display the UPnP screen.
To enable UPnP:
1.
Select the
Yes
radio box for
Do you want to enable UPnP?
to enable UPnP. If disabled, the
router will not allow for automatic device configuration.
2.
Enter an Advertisement Period, in minutes, for how often this wireless gateway should
broadcast its UPnP information to all devices within range.
3.
Enter an Advertisement Time to Live, expressed in hops, for each UPnP packet. (This is the
number of steps a packet is allowed to propagate before being discarded. Small values will
limit the UPnP broadcast range (recommended).)

Troubleshooting
This chapter gives information about troubleshooting your ProSafe 802.11g Wireless VPN
Firewall. After each problem description, instructions are provided to help you diagnose and solve
the problem.
Basic Functioning
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 30 seconds, 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 green.
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 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.

Troubleshooting
v1.0, September 2007
LEDs Never Turn Off
When the firewall is turned on, the LEDs turn on briefly and then turn off. If all the LEDs stay on,
there is a fault within the firewall.
If all LEDs 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
“Restoring the Default Configuration and
Password” on page 9-6
.
If the error persists, you might have a hardware problem and should contact technical support.
LAN or Internet Port LEDs Not On
If either the LAN LEDs or Internet LED 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
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 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 PC on your local
network, check the following:
•
Check the Ethernet connection between the PC and the firewall as described in the previous
section.
•
Make sure your PC’s IP address is on the same subnet as the firewall. 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.

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 firewall and reboot your PC.
•
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
“Restoring the Default Configuration and
Password” on page 9-6
.
•
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 http://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.
