Appendix A: Troubleshooting

This appendix consists of two parts: “Common Problems and Solutions” and “Frequently Asked Questions.” Provided are possible solutions to problems regarding the installation and operation of the Router. If your situation is described here, the problem should be solved by applying the corresponding solution. If you can’t find an answer here, check the Network Everwhere website at www.net- workeverywhere.com.

1. I need to set a static IP address on a PC.

The Router, by default, assigns an IP address range of 192.168.1.100 to

192.168.1.149 using the DHCP server on the Router. To set a static IP address, you can only use the ranges 192.168.1.2 to 192.168.1.99 and 192.168.1.151 to

192.168.1.254. Each PC or network device that uses TCP/IP must have a unique address to identify itself in a network. If the IP address is not unique to a network, Windows will generate an IP conflict error message. You can assign a static IP address to a PC by performing the following steps:

For Windows 98 SE and Me:

A. Click Start, Settings, and Control Panel. Double-click Network. B. In The following network components are installed box, select the TCP/IP->

associated with your Ethernet adapter. If you only have one Ethernet adapter installed, you will only see one TCP/IP line with no association to an Ethernet adapter. Highlight it and click the Properties button.

C. In the TCP/IP properties window, select the IP address tab, and select Specify

an IP address. Enter a unique IP address that is not used by any other computer on the network connected to the Router. You can only use an IP address in the ranges 192.168.1.2 to 192.168.1.99 and 192.168.1.151 to

192.168.1.254. Make sure that each IP address is unique for each PC or network device.

D. Click the Gateway tab, and in the New Gateway prompt, enter 192.168.1.1,

which is the default IP address of the Router. Click the Add button to accept the entry.

E. Click the DNS tab, and make sure the DNS Enabled option is selected. Enter

the Host and Domain names (e.g., John for Host and home for Domain). Enter the DNS entry provided by your ISP. If your ISP has not provided the DNS IP address, contact your ISP to get that information or go to its website for the information.

F. Click the OK button in the TCP/IP properties window, and click Close or the

OK button for the Network window.

G. Restart the computer when prompted.

F. Check the Enable option for the port services you want to use. Consider the

example below:

Customized Ext. Port TCP UDP IP Address Enable Application Web server 80 to 80 X X 192.168.1.100 X FTP server 21 to 21 X 192.168.1.101 X SMTP (outgoing)25 to 25 X X 192.168.1.102 X POP3 (incoming) 110 to 110 X X 192.168.1.102 X

When you have completed the configuration, click the Apply button.

7. 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:

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

address of the Router. Go to the Advanced => Forwarding tab and click

the View Port Range Forwarding button. B. Enter any name you want to use for the Customized Application. C. Enter the Ext. 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. D. Check the protocol you will be using, TCP and/or UDP. E. 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 D: Finding the MAC Address and IP Address for Your Ethernet Adapter” for details on getting an IP address.

Change the IP address for the Router to another subnet to avoid a conflict between the VPN IP address and your local IP address. For example, if your VPN server assigns an IP address 192.168.1.X (X is a number from 1 to 254) and your local LAN IP address is 192.168.1.X (X is the same number used in the VPN IP address), the Router will have difficulties routing information to the right location. If you change the Router’s IP address to 192.168.2.1, that should solve the problem. Change the Router’s IP address through the Setup tab of the web interface. If you assigned a static IP address to any computer or network device on the network, you need to change its IP address accordingly to

192.168.2.Y (Y being any number from 1 to 254). Note that each IP address must be unique within the network.

Your VPN may require port 500/UDP packets to be passed to the computer that is connecting to the IPSec server. Refer to “Problem #7, I need to set up online game hosting or use other Internet applications” for details.

Check the Network Everywhere website for more information at www.net- workeverywhere.com.

6. I need to set up a server behind my Router.

To use a server like a web, ftp, or mail server, you need to know the respective port numbers they are using. For example, port 80 (HTTP) is used for web; port 21 (FTP) is used for FTP, and port 25 (SMTP outgoing) and port 110 (POP3 incoming) are used for the mail server. You can get more information by viewing the documentation provided with the server you installed. Follow these steps to set up port forwarding through the Router’s web-based utility. We will be setting up web, ftp, and mail servers.

A. 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 Advanced => Forwarding tab and

click the View Port Range Forwarding button. B. Enter any name you want to use for the Customized Application. C. Enter the Ext. Port range of the service you are using. For example, if you

have a web server, you would enter the range 80 to 80. D. Check the protocol you will be using, TCP and/or UDP. E. 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 D: Finding the MAC Address and IP Address for Your Ethernet

Adapter” for details on getting an IP address.

9. I forgot my password, or the password prompt always appears when saving settings to the Router.

Reset the Router to factory default by pressing the Reset button for 30 seconds and then releasing it. If you are still getting prompted for a password when saving settings, then perform the following steps:

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

address of the Router. Enter the default password admin, and click the Password tab.

B. Enter a different password in the Router Password field, and enter this new

password in the second field to confirm the password.

C. Click the Apply button.

10. I am a PPPoE user, and I need to remove the proxy settings or the dial-up popup 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: A. Click Start, Settings, and Control Panel. Double-click Internet Options. B. Click the Connections tab. C. Click the LAN settings button and remove anything that is checked. D. Click the OK button to go back to the previous screen. E. Click the option Never dial a connection. This will remove any dial-up

pop-ups for PPPoE users.

For Netscape 4.7 or higher: A. Start Netscape Navigator, and click Edit, Preferences, Advanced, and

Proxies.

B. Make sure you have Direct connection to the Internet selected on this

screen.

C. Close all the windows to finish.

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

Hold the Reset button for up to 30 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.

F. Check the Enable option for the port services you want to use. Consider the

example below:

Customized Ext. Port TCP UDP IP Address Enable Application UT 7777 to 27900 X X 192.168.1.100 X Halflife 27015 to 27015 X X 192.168.1.105 X PC Anywhere 5631 to 5631 X 192.168.1.102 X VPN IPSEC 500 to 500 X 192.168.1.100 X

When you have completed the configuration, click the Apply button.

8. 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:

A. 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 Advanced => Forwarding tab and

click the View Port Range Forwarding button. B. Disable or remove the entries you have entered for forwarding. Keep this

information in case you want to use it at a later time. C. Click the DMZ Host tab. D. Enter the Ethernet adapter’s IP address of the computer you want exposed

to the Internet. This will bypass the NAT firewall for that computer. Please

refer to “Appendix D: Finding the MAC Address and IP Address for Your

Ethernet Adapter” for details on getting an IP address.

Once completed with the configuration, click the Apply button.

refresh the screen, until you see the login status display as Connected.

G. Click the Apply button to continue.

If the connection is lost again, follow steps E to G to re-establish connection.

15. I can't access my email, web, or VPN, 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:

A. To connect to the Router, go to the web browser, and enter

http://192.168.1.1 or the IP address of the Router. B. Enter the password, if asked. (The default password is admin.) C. Click the Advanced => Filter tab. D. Look for the MTU option, and select Enable. In the Size field, enter 1492. E. Click the Apply 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 1400 1362 1300

16. I need to use port triggering.

Port triggering looks at the outgoing port services used and will trigger the Router to open a specific port, depending on which port an Internet application uses. Follow these steps:

A. To connect to the Router, go to the web browser, and enter

http://192.168.1.1 or the IP address of the Router. B. Enter the password, if asked. (The default password is admin.) C. Click the Advanced => Forwarding tab, and click the Port Trigger button. D. Enter any name you want to use for the Application Name. E. Enter the Triggered Port Range. Check with your Internet application

provider for more information on which outgoing port services it is using. F. Enter the Incoming Port Range. Check with your Internet Application

provider for more information on which incoming port services are

required by the Internet application.

12. I need to upgrade the firmware.

In order to upgrade the firmware with the latest features, you need to go to the Network Everywhere website and download the latest firmware at www.net- workeverywhere.com. Follow these steps:

A. Go to the Linksys website at http://www.networkeverywhere.com and

download the latest firmware.

B. To upgrade the firmware, follow the steps in the Help section found in

“Chapter 5: The Router’s Web-based Utility.”

13. The firmware upgrade failed, and/or the Diag LED is flashing.

The upgrade could have failed for a number of reasons. Follow these steps to upgrade the firmware and/or make the Diag LED stop flashing:

A. If the f irmware 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.

B. Set a static IP address on the PC; refer to “Problem #1, I need to set a stat-

ic 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

C. Perform the upgrade using the TFTP program or the Router’s web-based

utility through its Help 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 dialup 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.

A. To connect to the Router, go to the web browser, and enter

http://192.168.1.1 or the IP address of the Router. B. Enter the password, if asked. (The default password is admin.) C. In the Setup tab, select the option Keep Alive, and set the Redial Period

option at 20 (seconds). D. Click the Apply button. E. Click the Status tab, and click the Connect button.

What is the maximum number of IP addresses that the Router will support? The

Router will support up to 253 IP addresses.

Is IPSec Pass-Through supported by the Router? Yes, it is a built-in feature that

the Router automatically enables.

Where is the Router installed on the network? In a typical environment, the

Router is installed between the cable/DSL modem and the LAN. Plug the Router into the cable/DSL modem’s Ethernet port.

Does the Router support IPX or AppleTalk? No. TCP/IP is the only protocol stan-

dard 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 LAN to LAN connections, but those protocols cannot connect from Internet to LAN.

What is Network Address Translation and what is it used for? Network Address

Translation (NAT) translates multiple IP addresses on the private LAN to one public address that is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is never transmitted on the Internet. Furthermore, NAT allows the Router to be used with low cost Internet accounts, such as DSL or cable modems, 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 Router support any operating system other than Windows 98 SE,

Windows 2000, Windows NT, or Windows XP? Yes, but Network Everywhere

does not, at this time, provide technical support for setup, configuration or troubleshooting of any non-Windows operating systems.

Does the Router support ICQ send file? 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 set-

ting. The Internet user can then send a file to a user behind the Router.

I set up an Unreal Tournament Server, but others on the LAN 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 LAN computers and forward ports

Frequently Asked Questions

17. The Diag LED stays lit continuously.

• The Diag LED lights up when the device is first powered on. Then, the system will boot up itself and check for proper operation. After finishing the checking procedure, the LED turns off to show that the system is working fine. If the LED remains lit 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.

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 ON. Connect to it and check its settings. (If you cannot connect to it, check the LAN and power connections.)

How will I be notified of new Router firmware upgrades? All Network

Everywhere firmware upgrades are posted on the Linksys website at www.networkeverywhere.com, where they can be downloaded for free. The Router’s f irmware can be upgraded with TFTP programs. If the Router’s Internet connection is working well, there is no need to download a newer firmware version, unless that version contains new features that you would like to use. Downloading a more current version of Router firmware will not enhance the quality or speed of your Internet connection, and may disrupt your current connection stability.

Will the Router function in a Macintosh environment? Yes, but the Router’s setup

pages are accessible only through Internet Explorer 4.0 or Netscape Navigator 4.0 or higher for Macintosh.

I am not able to get the web configuration screen for the Router. What can I do?

You may have to remove the proxy settings on your Internet browser, e.g., Netscape Navigator or Internet Explorer. Or remove the dial-up settings on your browser. Check with your browser documentation, and make sure that your browser is set to connect directly and that any dial-up is disabled. 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.

What is DMZ Hosting? Demilitarized Zone (DMZ) allows one IP address (com-

puter) to be exposed to the Internet. Some applications require multiple TCP/IP ports to be open. It is recommended that you set your computer with a static IP if you want to use DMZ Hosting. To get the LAN IP address, see “Appendix D: Finding the MAC Address and IP Address for Your Ethernet Adapter.”

If DMZ Hosting is used, does the exposed user share the public IP with the Router?

No.

Does the Router pass PPTP packets or actively route PPTP sessions? The Router

allows PPTP packets to pass through.

Is the Router cross-platform compatible? Any platform that supports Ethernet

and TCP/IP is compatible with the Router.

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 (8080 usually works well but is used for remote admin. You may have to disable this.), and 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 Router from your ISP.

Can multiple gamers on the LAN 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 Router? The default client

port for Half-Life is 27005. The computers on your LAN 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 LAN (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 for more information.

If all else fails in the installation, what can I do? Reset the Router by holding

down the reset button for about 30 seconds. Reset your cable or DSL modem by powering the unit off and then on. Obtain and flash the latest firmware release that is readily available on the Network Everywhere website, www.networkeverywhere.com.
