I am not getting an IP address on the Internet with my Internet connection.

Verify the connection:

Make sure you are using the right Internet connection settings. Contact your ISP to see if your Internet

connection type is RFC 1483 Bridged, RFC 2516 PPPoE, or RFC 2364 PPPoA, or Bridged Mode Only.

Please refer to the Setup section of “Chapter 5: Configuring the ADSL2 Modem” for details on Internet

connection settings. Verify that the VPI and VCI settings are correct.

2.

Make sure you have the right cable. Check to see if the Modem column has a solidly lit ADSL LED.

3.

Make sure the cable connecting from your Modem’s ADSL port is connected to the wall jack of the

ADSL service line.

4.

Turn off the computer and Modem. Wait 30 seconds, and then turn on the Modem, and computer.

Check the Status tab of the Modem’s web-based utility to see if you get an IP address.

3.

I forgot my password, or the password prompt always appears when I am saving settings to the

Gateway.

•

Reset the Modem to factory default by pressing the Reset button for 10 seconds and then releasing it. If

you are still getting prompted for a password when saving settings, then perform the following steps:

1.

Access the Modem’s web-based utility by going to http://192.168.1.1 or the IP address of the Modem.

Enter the default username and password

admin

, and click the

Administrations

=>

Management

tab.

2.

Enter a different password in the Modem Password field, and enter the same password in the second

field to confirm the password.

3.

Click the

Save Settings

button.

4.

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

Hold the

Reset

button for 10 seconds and then release it. This will return the Internet settings, password,

forwarding, and other settings on the Modem to the factory default settings. In other words, the Modem will

revert to its original factory configuration.

5.

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/international.

•

Follow these steps:

1.

Go to the Linksys website at http://www.linksys.com/international and download the latest firmware.

2.

To upgrade the firmware, follow the steps in the Administration section found in

“Chapter 5:

Configuring the ADSL2 Modem.”

6.

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.

1.

To connect to the Modem, go to the web browser, and enter http://192.168.1.1 or the IP address of the

Modem.

2.

Enter the username and password, if asked. (The default username and password is admin.)

3.

On the Setup screen, select the option

Keep Alive

, and set the Redial Period option at 1 minute.

4.

Click the

Save Settings

button. Click the

Status

tab, and click the

Connect

button.

5.

You may see the login status display as Connecting. Press the F5 key to refresh the screen, until you

see the login status display as Connected.

6.

Click the

Save Settings

button to continue.

•

If the connection is lost again, follow steps 1- 6 to re-establish connection.

7.

The Power LED flashes continuously.

The Power LED lights up when the device is first powered up. In the 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.

8.

When I enter a URL or IP address, I get a time-out error or am prompted to retry.

•

Check if other computers work. If they do, ensure that your computer’s IP settings are correct (IP Address,

Subnet Mask, Default Gateway, and DNS). Restart the computer that is having a problem.

•

If the computers are configured correctly, but still not working, check the

Modem. 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.)

•

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

Frequently Asked Questions

What is the maximum number of IP addresses that the Modem will support?

The Modem will support up to 253 IP addresses.

Is IPSec Passthrough supported by the Modem?

Yes, it is a built-in feature that is enabed by default.

Where is the Modem installed on the network?

The Modem is installed between the ADSL wall jack and the LAN.

Does the Modem 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 LAN connection of the Modem support 100Mbps Ethernet?

The Modem supports 100Mbps over the auto-sensing Fast Ethernet 10/100 switch on the LAN side of the Modem.
