Troubleshooting

v1.0, February 2008

If any of these conditions does not occur, see the following table.

Connecting to the Wireless Voice Gateway Main Menu

If you are unable to access the gateway’s main menu from a PC on your local network, check the

following:

•

Check the Ethernet connection between the PC and the gateway as described in the previous

section.

•

Make sure that your PC’s IP address is on the same subnet as the gateway. If you are using the

recommended addressing scheme, your PC’s address should be in the range of 192.168.0.10 to

192.168.0.254. Refer to

“Preparing a Computer for Network Access:” in Appendix B

for more

information about IP address configuration.

Table 5-1. Basic Troubleshooting with LEDs

Problem

Action

Power LED is off.

If the Power and other LEDs are off when your gateway is turned on:

•

Make sure that the power cord is properly connected to your gateway

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.

LAN LEDs are off, but ports

are connected.

Check the following:

•

Make sure that the Ethernet cable connections are secure at the

gateway and at the hub or PC.

•

Make sure that power is turned on to the connected computer.

•

Be sure you are using the correct cable:

When connecting the gateway use the cable that was supplied.

Note:

If your PC’s IP address is shown as 169.254.x.x:

Recent versions of Windows and Mac OS 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 gateway and reboot your PC.

•

If your gateway’s IP address has been changed and you don’t know the current IP address,

clear the gateway’s configuration to factory defaults. This will set the gateway’s IP address to

192.168.0.1. This procedure is explained in

“Restoring Factory Default Configuration

Settings” on page 4-5

.

•

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 that 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 gateway does not save changes you have made, check the following:

•

When entering configuration settings, be sure to click

Apply

before moving to another menu

or page, 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 gateway is unable to access the Internet and your Online LED is on, you might need to

register the Cable MAC Address and Device MAC Address of you gateway with your cable

service provider.

Additionally, your PC may not have the gateway configured as its TCP/IP gateway. If your PC

obtains its information from the gateway by DHCP, reboot the PC and verify the gateway address

as described in

“Preparing a Computer for Network Access:” in Appendix B

.

Troubleshooting a TCP/IP Network Using a Ping Utility

Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet

to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP

network is made easier by using the ping utility in your PC or workstation.

Troubleshooting

v1.0, February 2008

Testing the LAN Path to Your Gateway

You can ping the gateway from your PC to verify that the LAN path to your gateway is set up

correctly.

To ping the gateway from a PC running Windows 95 or later:

1.

From the Windows toolbar, click

Start

, and then select Run.

2.

In the field provided, type ping followed by the IP address of the gateway, as in this example:

ping 192.168.0.1

3.

Click

OK

.

•

You should see a message like this one:

Pinging <

IP address

> with 32 bytes of data

•

If the path is working, you see this message:

Reply from <

IP address

>: bytes=32 time=NN ms TTL=xxx

•

If the path is not working, you see this message:

Request timed out

If the path is not functioning correctly, you could have one of the following problems:

•

Wrong physical connections

–

Make sure that the LAN port LED is on. If the LED is off, follow the instructions in

“LAN LEDs are off, but ports are connected.” on page 5-2

”.

–

Check that the corresponding Link LEDs are on for your network interface card and

for the hub ports (if any) that are connected to your workstation and gateway.

•

Wrong network configuration

–

Verify that the Ethernet card driver software and TCP/IP software are both installed

and configured on your PC or workstation.

–

Verify that the IP address for your gateway and your workstation are correct and that

the addresses are on the same subnet.

Testing the Path from Your PC to a Remote Device

After verifying that the LAN path works correctly, test the path from your PC to a remote device.

From the Windows run menu, type:

PING -n 10
