How can I block corrupted FTP downloads? 

If you are experiencing 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 of the Router, what can I do?

Reset the Router by

holding down the reset button until the Diag 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 readily 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.  The Router’s firmware can be upgraded with TFTP pro-
grams. 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 brows-
er 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 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 pro-
vided 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 2000, Windows NT, 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 files?

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 (8080 usually works well but is used for remote
admin. You may have to disable this.), and then in the [UWeb.WebServer] sec-
tion 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 multiple
logins with one public IP Address.

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 “+client-
port 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 version 1.0.1.3).
As far as hosting games, the HL server does not need to be in the DMZ. Just for-
ward port 27015 to the local IP address of the server computer.
