Wireless-G VPN Router with RangeBooster

Appendix A

the Router will send the data to whichever PC or network

device you set for DMZ hosting.) Follow these steps to set

DMZ hosting:

Access the Router’s Web-based Utility by going to

http://±9².±¶8.±.±

or the IP address of the Router. Go

to the

Firewall -> Port Forwarding

tab.

Disable the entries you have entered for forwarding.

Go to the

Firewall -> DMZ

tab.

Enter the Ethernet adapter’s IP address of the computer

you want exposed to the Internet. This will bypass the

NAT security for that computer.

Select

Enabled

to enable DMZ Hosting.

When you have completed the configuration, click

Save

Settings

.

I forgot my password, or the password prompt always

appears when saving settings to the Router.

Reset the Router to factory defaults by pressing the Reset

button for ten seconds and then releasing it. If you are still

getting prompted for a password when saving settings,

then perform the following steps:

Access the Router’s web interface by going to

http://192.168.1.1 or the IP address of the Router.

Enter the default password

admin

, and click the

Administration -> Management

tab.

Enter a different password in the

Admin Password

field,

and enter the same password in the

Re-enter to confirm

field to confirm the password.

Click

Save Settings

.

I am a PPPoE user, and I need to remove the proxy

settings or the dial-up pop-up window.

If you have proxy settings, you need to disable these on

your computer. Because the Router is the gateway for the

Internet connection, the computer does not need any

proxy settings to gain access. Please follow these directions

to verify that you do not have any proxy settings and that

the browser you use is set to connect directly to the LAN.

For Microsoft Internet Explorer µ.0 or higher:

Click

Start

,

Settings

, and

Control Panel

. Double-click

Internet Options

.

Click the

Connections

tab.

Click

LAN settings

and remove anything that is

checked.

Click

OK

to go back to the previous screen.

Click the option

Never dial a connection

. This will

remove any dial-up pop-ups for PPPoE users.

For Netscape ´.· or higher:

Netscape Navigator

, and click

,

Preferences

Proxies

.

Make sure you have

Direct connection to the Internet

selected on this screen.

Close all the windows to finish.

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

Hold the Reset button for 15 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.

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:

Go to the Linksys website at

www.linksys.com

and

download the latest firmware for your Router.

Extract the firmware file on your computer.

To upgrade the firmware, follow the steps in the

Upgrade section found in “Chapter 5: Configuring the

Wireless-G Router”.

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.

To connect to the Router, go to the web browser, and

enter

http://±9².±¶8.±.±

or the IP address of the

Router.

Enter the password, if asked (default password is

admin

).

On the

Setup -> Basic Setup

tab, select the option

Keep Alive

, and set the

Redial Period

option to

²0

(seconds).

Click

Save Settings

.

If the connection is lost again, follow steps 1 and 2 to re-

establish connection.

I can’t access my email, web, or VPN, 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
