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

Hold the

Reset

button for five 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.

12.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

and download the latest firmware.

2.

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

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 PC; refer to “Problem #2, 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.

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.

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.)

15.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.)

1400

1362

1300

16.The Power LED keeps flashing.

The Power LED flashes when the Router is first powered up. Meantime, the Router will boot up itself and

check for proper operation. After finishing the checking procedure, the LED stays solid to show that the

Router is working fine. If the LED keeps flashing after this time, the Router 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 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

,

Frequently Asked Questions

Wireless-N Gigabit Gaming Router

Frequently Asked Questions

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 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 LAN to LAN connections, but

those protocols cannot connect from the Internet to a LAN.

Does the Internet connection of the Router support 100Mbps Ethernet?

The Router’s current hardware design supports up to 100Mbps Ethernet on its Internet port; however, the Internet

connection speed will vary depending on the speed of your broadband connection. The Router also supports

100Mbps over the auto-sensing Fast Ethernet 10/100 switch on the LAN side of the Router.

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 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 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 setting. The Internet user can then send a file

to a user behind the Router.

Frequently Asked Questions

Wireless-N Gigabit Gaming 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 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 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.

How can I block corrupted FTP downloads?

If you are get corrupted files when you download a file with your FTP client, try using another FTP program.

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 until the Power LED fully turns on and off. Reset your cable or

DSL modem by powering the unit off and then on. Obtain and flash the latest firmware release that is available on

the Linksys website, www.linksys.com.

How will I be notified of new Router firmware upgrades?

All Linksys firmware upgrades are posted on the Linksys website at www.linksys.com, where they can be

downloaded for free. To upgrade the Router’s firmware, use the Administration - Firmware Upgrade tab of the

Router’s web-based utility. 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
