OR
Configure your router to spoof your computer’s MAC address. This can be done in the Basic
Settings menu. Refer to
“How to Manually Configure Your Internet Connection” on
page 3-15
.
If your router can obtain an IP address, but your computer is unable to load any Web pages from
the Internet:
•
Your computer 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 computer and verify the DNS address as described in
“Verifying TCP/IP Properties” on
page C-6
. Alternatively, you may configure your computer manually with DNS addresses, as
explained in your operating system documentation
.
•
Your computer may not have the router configured as its TCP/IP gateway.
If your computer obtains its information from the router by DHCP, reboot the computer 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 on your computer.
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 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:
3.
Click on 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 the LAN port LED is on. If the LED is off, follow the instructions in
“Local or Internet Port LEDs Not On
” on
page 9-2
.
—
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 computer.
—
Verify that the IP address for your router and your computer 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 3-15
.
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 7-9
).
•
Use the factory 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 Reset button on the rear panel of the router.
1.
Press and hold the Reset button (about 1.5 to 2 minutes to ensure reset).
2.
Release the Reset button and wait for the router to reboot.
Troubleshooting the Web Configuration Interface
The Web Configuration Interface contains an online Help system that provides information on
each configuration screen. If you do not find the answer to your question in the online Help, refer
to the NETGEAR Knowledge Base at:
A few common issues are described below.

Problems with Date and Time
The E-Mail menu in the Content Filtering section displays the current date and time of day. The
WGT634U Wireless Media 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, select or clear the check box marked “Adjust for Daylight Savings
Time”.
Problems with Saving Configuration Changes
When you click Apply to save your configuration changes, the Web Configuration Interface
sometimes does not feedback that the changes have been saved.
To make sure that your changes were saved, switch to a different configuration screen and then
switch back again. Your configuration changes should be displayed.
Troubleshooting the USB Drive
USB Hub Attached to the WGT634U is not Visible
Only one USB flash disk or external disk is supported at this time.
File Copy of Large Files to the USB Disk FAT32 File System Fails
The FAT32 file system only supports up to 4GB for an individual file. You cannot copy a 5GB file
from an NTFS system to a FAT32 file system.
Cannot Connect to the USB Drive Using Microsoft Networking
Make sure that Microsoft Networking is enabled. For more information, please contact Microsoft
for assistance.

If you cannot connect to the USB drive using the host name, such as \\WGT634U, use the IP
address.
You can also connect to the USB drive from a Web browser. Type \\ followed by the router’s IP
address, for example:
\\192.168.1.1
Cannot Attach USB Drive to USB Port
If your USB flash drive is too wide to attach to the USB port, you can purchase a USB extension
cable to attach your drive. USB cables are not included with the WGT634U Wireless Media
Router.
Troubleshooting the Firmware Upgrade
You must upgrade the firmware periodically when you log in to the administrator console. You can
use the Firmware Upgrade Assistant that appears after login or use the Router Upgrade menu in
the Main ten ace section of the main menu.
Note:
When performing a router upgrade, you should use a LAN wired connection directly
attached to the router. Do not use a wireless connection to upgrade the firmware.
When uploading software to the WGT634U Wireless Media Router, it is important not to:
•
Interrupt the upload by turning off your computer
•
Interrupt the Web browser by closing the window, clicking a link, or loading a new page.
•
Interrupt the upload by turning off the router. When the upload is complete, your router will
automatically restart.
Warning:
If the Web browser, computer, or router is interrupted, it may corrupt the software.
