Common Problems and Solutions

Wireless-G Broadband Router with RangeBooster

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.)

3.

Look for the MTU option, and select

Manual

. In the

Size

field, enter 1492.

4.

Click the

Save Settings

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.The Power LED keeps flashing.

The Power LED flashes 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 stays solid to show that the

system is working fine. If the LED keeps flashing 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.

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

Frequently Asked Questions

After using SecureEasySetup, my existing wireless devices can no longer connect to the Router.

SecureEasySetup uses WPA-Personal encryption. If your current wireless devices do not support WPA-Personal

security, then you cannot use SecureEasySetup on your network. You will need to manually configure your

network security using the encryption supported by your existing devices. Re-run the Setup Wizard. On the

Welcome

screen for the Setup Wizard, click

Click Here to Start

and follow the on-screen instructions. On the

Configure Wireless Settings

screen, click

Enter Wireless Settings Manually

and continue to follow the on-

screen instructions. For more information, refer to “Chapter 5: Setting up the Wireless-G Broadband Router with

RangeBooster.”

How do I set up additional devices using SecureEasySetup?

Repeat the SecureEasySetup process for each device until all of your devices have been configured.

Where is my SecureEasySetup button?

On the Router, the SecureEasySetup button is located on the front panel. The button should be lighted either

orange or white. For other SecureEasySetup devices, refer to each wireless device's documentation to locate the

button on that device.

I have devices that support WPA-Personal security, but do not have SecureEasySetup.

Can I still use

SecureEasySetup?

Yes. Print out the wireless security settings at the end of the SecureEasySetup process, and then manually

configure the settings for your non-SecureEasySetup devices. Refer to each wireless device’s documentation for

instructions on how to enter these settings.

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.

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 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 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

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.

Frequently Asked Questions

Wireless-G Broadband Router with RangeBooster

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 E: 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, access restriction policies, port

forwarding, advanced routing, and DDNS.

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.

Can I run an application from a remote computer over the wireless network?

This will depend on whether or not the application is designed to be used over a network. Consult the

application’s documentation to determine if it supports operation over a network.

What is the IEEE 802.11g standard?

It is one of the IEEE standards for wireless networks. The 802.11g standard allows wireless networking hardware

from different manufacturers to communicate, provided that the hardware complies with the 802.11g standard.

The 802.11g standard states a maximum data transfer rate of 54Mbps and an operating frequency of 2.4GHz.
