Appendix A: Troubleshooting
Common Problems and Solutions
Wireless-G ADSL Gateway with 2 Phone Ports
If you are having difficulties getting any Internet game, server, or application to function properly, consider
exposing one computer to the Internet using DeMilitarized Zone (DMZ) hosting. This option is available when
an application requires too many ports or when you are not sure which port services to use. Make sure you
disable all the forwarding entries if you want to successfully use DMZ hosting, since forwarding has priority
over DMZ hosting. (In other words, data that enters the Gateway will be checked first by the forwarding
settings. If the port number that the data enters from does not have port forwarding, then the Gateway will
send the data to whichever computer or network device you set for DMZ hosting.)
•
Follow these steps to set DMZ hosting:
1.
Access the Gateway’s web-based utility by going to http://192.168.1.1 or the IP address of the
Gateway. Go to the Applications and Gaming => DMZ tab. Click Enabled and enter the IP of the
computer.
2.
Check the Port Forwarding pages and disable or remove the entries you have entered for forwarding.
Keep this information in case you want to use it at a later time.
•
Once completed with the configuration, click the
Save Settings
button.
9.
I forgot my password, or the password prompt always appears when I am saving settings to the
Gateway.
•
Reset the Gateway to factory default by pressing the Reset button for 10 seconds and then releasing it. If
you are still getting prompted for a password when saving settings, then perform the following steps:
1.
Access the Gateway’s web-based utility by going to http://192.168.1.1 or the IP address of the
Gateway. Enter the default username and password
admin
, and click the
Administrations
=>
Management
tab.
2.
Enter a different password in the Gateway Password field, and enter the same password in the
second field to confirm the password.
3.
Click the
Save Settings
button.
10.I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up window.
If you have proxy settings, you need to disable these on your computer. Because the Gateway is the gateway
for the Internet connection, the computer does not need any proxy settings to gain access.
Please follow
these directions to verify that you do not have any proxy settings and that the browser you use is set to
connect directly to the network.
•
For Microsoft Internet Explorer 5.0 or higher:
1.
Click
Start,
Settings
, and
Control Panel
. Double-click Internet Options.
2.
Click the
Connections
tab.
3.
Click the
LAN settings
button and remove anything that is checked.
4.
Click the
OK
button to go back to the previous screen.
5.
Click the option
Never dial a connection
.
This will remove any dial-up pop-ups for PPPoE users.

1.
Start
Netscape Navigator
, and click
Edit
,
Preferences
,
Advanced
, and
Proxies
.
2.
Make sure you have Direct connection to the Internet selected on this screen.
3.
Close all the windows to finish.
11.To start over, I need to set the Gateway to factory default.
Hold the
Reset
button for 10 seconds and then release it. This will return the Internet settings, password,
forwarding, and other settings on the Gateway to the factory default settings. In other words, the Gateway will
revert to its original factory configuration.
12.I need to upgrade the firmware.
In order to upgrade the firmware with the latest features, you need to go to the Linksys international website
and download the latest firmware at www.linksys.com/international.
•
Follow these steps:
1.
Go to the Linksys international website at http://www.linksys.com/international and select your
region or country.
2.
Click the
Products
tab and select the Gateway.
3.
On the Gateway’s webpage, click
Firmware
, and then download the latest firmware for the Gateway.
4.
To upgrade the firmware, follow the steps in the Administration section found in
Chapter 4:
Configuring the Gateway
.
13.The firmware upgrade failed, and/or the Power LED is flashing.
The upgrade could have failed for a number of reasons.
Follow these steps to upgrade the firmware and/or
make the Power LED stop flashing:
•
If the firmware upgrade failed, use the TFTP program (it was downloaded along with the firmware). Open
the pdf that was downloaded along with the firmware and TFTP program, and follow the pdf’s
instructions.
•
Set a static IP address on the computer; refer to “Problem #1, I need to set a static IP address.” Use the
following IP address settings for the computer you are using:
IP Address: 192.168.1.50
Subnet Mask: 255.255.255.0
Gateway: 192.168.1.1
•
Perform the upgrade using the TFTP program or the Gateway’s web-based utility through its
Administration tab.
14.My DSL service’s PPPoE is always disconnecting.
PPPoE is not actually a dedicated or always-on connection.
The DSL ISP can disconnect the service after a
period of inactivity, just like a normal phone dial-up connection to the Internet.
•
There is a setup option to “keep alive” the connection.
This may not always work, so you may need to re-
establish connection periodically.

1300
16.The Power LED flashes continuously.
The Power LED lights up when the device is first powered up. In the meantime, the system will boot up itself
and check for proper operation. After finishing the checking procedure, the LED remains steady to show that
the system is working fine. If the LED continues to flash after this time, the device is not working properly. Try
to flash the firmware by assigning a static IP address to the computer, and then upgrade the firmware. Try
using the following settings, IP Address: 192.168.1.50 and Subnet Mask: 255.255.255.0.
17.When I enter a URL or IP address, I get a time-out error or am prompted to retry.
•
Check if other computers work. If they do, ensure that your computer’s IP settings are correct (IP Address,
Subnet Mask, Default Gateway, and DNS). Restart the computer that is having a problem.
•
If the computers are configured correctly, but still not working, check the
Gateway. Ensure that it is
connected and powered on. Connect to it and check its settings. (If you cannot connect to it, check the
network and power connections.)

Frequently Asked Questions
What is the maximum number of IP addresses that the Gateway will support?
The Gateway will support up to 253 IP addresses.
Is IPSec Passthrough supported by the Gateway?
Yes, it is a built-in feature that is enabled by default.
Where is the Gateway installed on the network?
In a typical environment, the Gateway is installed between the ADSL wall jack and the network.
Does the Gateway support IPX or AppleTalk?
No. TCP/IP is the only protocol standard for the Internet and has become the global standard for communications.
IPX, a NetWare communications protocol used only to route messages from one node to another, and AppleTalk, a
communications protocol used on Apple and Macintosh networks, can be used for network to network
connections, but those protocols cannot connect from the Internet to a network.
Do the Gateway’s network connections support 100Mbps Ethernet?
The Gateway supports 100Mbps over the auto-sensing network ports.
What is Network Address Translation and what is it used for?
Network Address Translation (NAT) translates multiple IP addresses on the private network to one public address
that is sent out to the Internet. This adds a level of security since the address of a computer connected to the
private network is never transmitted on the Internet. Furthermore, NAT allows the Gateway to be used with low
cost Internet accounts when only one TCP/IP address is provided by the ISP. The user may have many private
addresses behind this single address provided by the ISP.
Does the Gateway support any operating system other than Windows 98SE, Windows Millennium,
Windows 2000, or Windows XP?
Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshooting of
any non-Windows operating systems.
Does the Gateway support ICQ send file?

Frequently Asked Questions
Wireless-G ADSL Gateway with 2 Phone Ports
Yes, with the following fix: click ICQ menu -> preference -> connections tab->, and check I am behind a firewall
or proxy. Then set the firewall time-out to 80 seconds in the firewall setting. The Internet user can then send a file
to a user behind the Gateway.
I set up an Unreal Tournament Server, but others on the network cannot join. What do I need to do?
If you have a dedicated Unreal Tournament server running, you need to create a static IP for each of the network’s
computers and forward ports 7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. You can
also use a port forwarding range of 7777 ~ 27900. If you want to use the UT Server Admin, forward another port.
(Port 8080 usually works well but is used for remote admin. You may have to disable this.) Then in the
[UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080 (to match the mapped port above) and
ServerName to the IP assigned to the Gateway from your ISP.
Can multiple gamers on the network get on one game server and play simultaneously with just one
public IP address?
It depends on which network game or what kind of game server you are using.
For example, Unreal Tournament
supports multi-login with one public IP.
How do I get Half-Life: Team Fortress to work with the Gateway?
The default client port for Half-Life is 27005.
The computers on your network need to have “+clientport 2700x”
added to the HL shortcut command line; the x would be 6, 7, 8, and on up. This lets multiple computers connect
to the same server. One problem: Version 1.0.1.6 won’t let multiple computers with the same CD key connect at
the same time, even if on the same network (not a problem with 1.0.1.3).
As far as hosting games, the HL server
does not need to be in the DMZ. Just forward port 27015 to the local IP address of the server computer.
The web page hangs; downloads are corrupt, or nothing but junk characters are being displayed on the
screen. What do I need to do?
Force your Ethernet adapter to 10Mbps or half duplex mode, and turn off the “Auto-negotiate” feature of your
Ethernet adapter as a temporary measure. (Please look at the Network Control Panel in your Ethernet adapter’s
Advanced Properties tab.) Make sure that your proxy setting is disabled in the browser. Check our website at
www.linksys.com/international for more information.
If all else fails in the installation, what can I do?
Reset the Gateway by holding down the reset button until the Power LED fully turns on and off. Reset your DSL
modem by powering the unit off and then on.
Obtain and flash the latest firmware release that is readily available
on the Linksys international website, www.linksys.com/international.
How will I be notified of new Gateway firmware upgrades?
All Linksys firmware upgrades are posted on the Linksys international website at www.linksys.com/international,
where they can be downloaded for free. To upgrade the Gateway’s firmware, use the Administration tab of the
