OR

Configure your router to spoof your PC’s MAC address. This can be done in the Basic Settings

menu. Refer to

“How to Manually Configure Your Internet Connection” on page 2-12

.

If your router can obtain an IP address, but your PC is unable to load any web pages from the

Internet:

•

Your PC may not recognize any DNS server addresses.

A DNS server is a host on the Internet that translates Internet names (such as www addresses)

to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS

servers for your use. If you entered a DNS address during the router’s configuration, reboot

your PC and verify the DNS address as described in

“Verifying TCP/IP Properties” on

page C-6

. Alternatively, you may configure your PC manually with DNS addresses, as

explained in your operating system documentation

.

•

Your PC may not have the router configured as its TCP/IP gateway.

If your PC obtains its information from the router by DHCP, reboot the PC and verify the

gateway address as described in

“Verifying TCP/IP Properties” on page C-6

.

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 very easy by using the ping utility in your PC or workstation.

Testing the LAN Path to Your Router

You can ping the router from your PC to verify that the LAN path to your router is set up correctly.

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

1.

From the Windows toolbar, click on the Start button and select Run.

2.

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

ping 192.168.0.1

3.

Click on OK.

You should see a message like this one:

Pinging <IP address> with 32 bytes of data

Troubleshooting

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

“LAN

or WAN Port LEDs Not On

” on

page 7-2

.

—

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 router.

•

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 router 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

<

IP address

>

where <

IP address

> is the IP address of a remote device such as your ISP’s DNS server.

If the path is functioning correctly, replies as in the previous section are displayed. If you do not

receive replies:

—

Check that your PC has the IP address of your router listed as the default gateway. If the IP

configuration of your PC is assigned by DHCP, this information will not be visible in your

PC’s Network Control Panel. Verify that the IP address of the router is listed as the default

gateway as described in

“Verifying TCP/IP Properties” on page C-6

.

—

Check to see that the network address of your PC (the portion of the IP address specified

by the netmask) is different from the network address of the remote device.

—

Check that your cable or DSL modem is connected and functioning.

—

If your ISP assigned a host name to your PC, enter that host name as the Account Name in

the Basic Settings menu.

—

Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many

broadband ISPs restrict access by only allowing traffic from the MAC address of your

broadband modem, but some ISPs additionally restrict access to the MAC address of a

single PC connected to that modem. If this is the case, you must configure your router to

“clone” or “spoof” the MAC address from the authorized PC. Refer to

“How to Manually

Configure Your Internet Connection” on page 2-12

.

Restoring the Default Configuration and Password

This section explains how to restore the factory default configuration settings, changing the

router’s administration password to

password

and the IP address to 192.168.0.1. You can erase the

current configuration and restore factory defaults in two ways:

•

Use the Erase function of the router (see

“Erasing the Configuration” on page 5-8

).

•

Use the Default Reset button on the rear panel of the router. Use this method for cases when

the administration password or IP address is not known.

To restore the factory default configuration settings without knowing the administration password

or IP address, you must use the Default Reset button on the rear panel of the router.

1.

Press and hold the Default Reset button until the Test LED turns on (about 10 seconds).

2.

Release the Default Reset button and wait for the router to reboot.

Problems with Date and Time

The E-Mail menu in the Content Filtering section displays the current date and time of day. The

WGR614 router uses the Network Time Protocol (NTP) to obtain the current time from one of

several Network Time Servers on the Internet. Each entry in the log is stamped with the date and

time of day. Problems with the date and time function can include:

•

Date shown is January 1, 2000. Cause: The router has not yet successfully reached a Network

Time Server. Check that your Internet access settings are configured correctly. If you have just

completed configuring the router, wait at least five minutes and check the date and time again.

•

Time is off by one hour. Cause: The router does not automatically sense Daylight Savings

Time. In the E-Mail menu, check or uncheck the box marked “Adjust for Daylight Savings

Time”.
