I need to set up online game hosting or use other Internet applications.

If you want to play online games or use Internet applications, most will work without doing any port

forwarding or DMZ hosting.

There may be cases when you want to host an online game or Internet

application. This would require you to set up the Router to deliver incoming packets or data to a specific

computer.

This also applies to the Internet applications you are using. The best way to get the information on

what port services to use is to go to the website of the online game or application you want to use. Follow

these steps to set up online game hosting or use a certain Internet application:

1.

Access the Router’s web interface by going to http://192.168.1.1 or the IP address of the Router. Go to

the Applications & Gaming => Port Forwarding tab.

2.

Enter any name you want to use for the Customized Application.

3.

Enter the External Port range of the service you are using. For example, if you want to host Unreal

Tournament (UT), you would enter the range 7777 to 27900.

4.

Check the protocol you will be using, TCP and/or UDP.

5.

Enter the IP address of the PC or network device that you want the port server to go to. For example,

if the web server’s Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the field

provided. Check “Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter” for

details on getting an IP address.

6.

Check the

Enable

option for the port services you want to use. Consider the example below:

When you have completed the configuration, click the

Save Settings

button.

9.

I can’t get the Internet game, server, or application to work.

If you are having difficulties getting any Internet game, server, or application to function properly, consider

exposing one PC 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 Router will be checked first by the forwarding settings.

If the port number that the data enters from does not have port forwarding, then the Router will send the data

to whichever PC or network device you set for DMZ hosting.)

Follow these steps to set DMZ hosting:

1.

Access the Router’s web-based utility by going to http://192.168.1.1 or the IP address of the Router.

Go to the Applications & Gaming => Port Forwarding tab.

2.

Disable or remove the entries you have entered for forwarding.

Keep this information in case you

want to use it at a later time.

3.

Go to the Applications & Gaming => DMZ tab.

4.

Select

Enable

next to DMZ. In the DMZ Host IP Address field, enter the IP address of the computer you

want exposed to the Internet.

This will bypass the NAT technology for that computer. Please refer to

“Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter” for details on getting

an IP address.

5.

Once completed with the configuration, click the

Save Settings

button.

10.I forgot my password, or the password prompt always appears when I am saving settings to the

Router.

Reset the Router 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 Router’s web-based utility by going to http://192.168.1.1 or the IP address of the Router.

Enter the default password admin, and click the Administrations => Management tab.

2.

Enter a different password in the Router Password field, and enter the same password in the second

field to confirm the password.

3.

Click the

Save Settings

button.

11.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 Router 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 LAN.

•

For Microsoft Internet Explorer 5.0 or higher:

1.

12.To start over, I need to set the Router to factory default.

Hold the

Reset

button for 10 seconds and then release it. This will return the password, forwarding, and other

settings on the Router to the factory default settings. In other words, the Router will revert to its original

factory configuration.

13.My power LED will not stop flashing.

Press and hold the reset button for five seconds. If this does not work, your firmware may be corrupted. To

upgrade the firmware, follow the steps in “Appendix C: Upgrading Firmware.”

14.I need to upgrade the firmware.

In order to upgrade the firmware with the latest features, you need to go to the Linksys website and download

the latest firmware at www.linksys.com.

Follow these steps:

1.

Go to the Linksys website at http://www.linksys.com and download the latest firmware.

2.

To upgrade the firmware, follow the steps in “Appendix C: Upgrading Firmware.”

15.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 PC; 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 Administration tab of the Router’s web-based utility.

16.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.

1.

To connect to the Router, go to the web browser, and enter http://192.168.1.1 or the IP address of the

Router.

2.

Enter the password, if asked. (The default password is admin.)

If the connection is lost again, follow steps 1- 6 to re-establish connection.

17.I can’t access my e-mail, web or I am getting corrupted data from the Internet.

The Maximum Transmission Unit (MTU) setting may need to be adjusted. By default, the MTU is set at 1500.

For most DSL users, it is strongly recommended to use MTU 1492.

•

If you are having some difficulties, perform the following steps:

1.

To connect to the Router, go to the web browser, and enter http://192.168.1.1 or the IP address of the

Router.

2.

Enter the password, if asked. (The default password is admin.)

3.

Look for the MTU option, and select

Manual

. In the Size field, enter 1492.

4.

Click the

Save Settings

button to continue.

•

If your difficulties continue, change the Size to different values. Try this list of values, one value at a time,

in this order, until your problem is solved:

1462

1362

1300

18.When I enter a URL or IP address, I get a time-out error or am prompted to retry.

•

Check if other PCs work. If they do, ensure that your workstation’s IP settings are correct (IP Address,

Subnet Mask, Default Gateway, and DNS). Restart the computer that is having a problem.

•

If the PCs are configured correctly, but still not working, check the Router. Ensure that it is connected and

powered on. Connect to it and check its settings. (If you cannot connect to it, check the LAN and power

connections.)

•

If the Router is configured correctly, check your Internet connection (DSL/cable modem, etc.) to see if it is

working correctly. You can remove the Router to verify a direct connection.

•

Manually configure the TCP/IP settings with a DNS address provided by your ISP.

•

Make sure that your browser is set to connect directly and that any dial-up is disabled. For Internet

Explorer, click

Tools

,

Internet Options

, and then the

Connection

tab. Make sure that Internet Explorer is

set to

Never dial a connection

. For Netscape Navigator, click

Edit

,

Preferences

,

Advanced

, and

Proxy

.

Make sure that Netscape Navigator is set to

Direct connection to the Internet

.

19.I cannot connect to the Internet.

•

For Cable users - Click on the Status tab and make sure you have the Internet IP address is not 0.0.0.0.

If

it is, click the DHCP Renew button, and wait a few minutes for the router to try and contact your service

provider.

For DSL users - 1) Make sure you have typed in your user name and password correctly.

Some service

providers use your full email address as the user name. If you are sure you have enter the right user

name, try using username@[isp.com], where isp.com is the name of your service provider. 2) Power down

your DSL Modem, your PC, and your router.

Then power on your DSL Modem, wait for the LEDs on the DSL

modem to stop flashing.

Power on your router and wait for the power LED to stop flashing.

Finally, power

20.My wireless-G speed seems to be slow.

•

Reposition the antenna.

•

Reposition the router so that it's higher up, above your other networking gear.

•

Change CTS Protection to Disable under advanced wireless settings.

21.I do not see a speed improvement while surfing wirelessly with my SRX equipment.

•

Your Internet connection is usually much slower than your wireless network with SRX equipment.

This

equipment will not affect the speed of your Internet connection.

•

You will see the most improvements in transferring or streaming files from one computer to another in

your network.

•

Your network speed will slow down if you have mixed 802.11g and SRX clients.
