• 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.
18. The Full/Col LED keeps flickering continuously.
• Check the Category 5 Ethernet network cable and its RJ-45 connectors.
• There may be interference with other network devices. Try removing
other PCs or network devices to see if the problem persists. Eliminate
each network device one at a time to determine the cause.

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 com-
munications 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 pri-
vate 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 95, Windows
98, Windows Millennium, Windows 2000, Windows NT, or Windows XP?
Yes, but Linksys does not, at this time, provide technical support for setup, con-
figuration 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.
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
