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”.
