17.The Power LED flashes continuously.
The Power LED lights up when the device is first powered up. Meantime, the system will boot up itself and
check for proper operation. After finishing the checking procedure, the LED remains steady to show that the
system is working fine. If the LED continues to flash 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.

Frequently Asked Questions
Wireless-G VPN Broadband Router
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 95, 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.
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.

Frequently Asked Questions
Wireless-G VPN Broadband Router
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 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, 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 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. To upgrade the Router’s firmware, use the System 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 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 (computer) 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 F: 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.
How many ports can be simultaneously forwarded?
Theoretically, the Router can establish 520 sessions at the same time, but you can only forward 10 ranges of
ports.
What are the advanced features of the Router?
The Router’s advanced features include Advanced Wireless settings, Filters, Port Forwarding, Routing, and DDNS.
What is the maximum number of VPN sessions allowed by the Router?
The maximum number depends on many factors. At least one IPSec session will work through the Router;
however, simultaneous IPSec sessions may be possible, depending on the specifics of your VPNs.
How can I check whether I have static or DHCP IP Addresses?
Consult your ISP to obtain this information.
How do I get mIRC to work with the Router?
Under the Port Forwarding tab, set port forwarding to 113 for the PC on which you are using mIRC.
Can the Router act as my DHCP server?
Yes. The Router has DHCP server software built-in.
