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

“Local or Internet 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.

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 192.168.1.1. 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 5 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

WGT624 v3 wireless 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, 2003. 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”.
