Troubleshoot PPPoE

If you are using PPPoE, try troubleshooting your Internet connection.

To troubleshoot a PPPoE connection:

1.

Launch a web browser from a computer or wireless device that is connected to the network.

2.

Type

http://www.routerlogin.net

.

A login window opens.

3.

Enter the

router

user name and password.

The user name is

admin

. The default password is

password

. The user name and password are

case-sensitive.

The BASIC Home page displays.

4.

Click the

ADVANCED

tab.

The ADVANCED Home page displays.

5.

In the Internet Port pane, click the

Connection Status

button.

The Connection Status window opens.

6.

Check the Connection Status windowto see if your PPPoE connection is up and working.

If the router is not connected, click the

Connect

button.

The

router

continues to attempt to connect indefinitely.

7.

If you cannot connect after several minutes, the router might be set up with an incorrect service name,

user name, or password, or your ISP might be experiencing a provisioning problem.

Unless you connect manually, the

router

does not authenticate using PPPoE until data is transmitted to

the network.

Troubleshoot Internet Browsing

If your

router

can obtain an IP address but your computer is unable to load any web pages from the

Internet, check the following:

•

The traffic meter is enabled, and the limit was reached.

By configuring the traffic meter not to block Internet access when the traffic limit is reached, you can

resume Internet access. If your ISP sets a usage limit, they might charge you for the overage.

•

Your computer might not recognize any DNS server addresses. A DNS server is a host on the Internet

that translates Internet names (such as www addresses) to numeric IP addresses.

Typically, your ISP provides the addresses of one or two DNS servers for your use. If you entered a

DNS address during the

router

’s configuration, restart your computer.

Troubleshooting

Alternatively, you can configure your computer manually with a DNS address, as explained in the

documentation for your computer.

•

The

router

might not be configured as the default gateway on your computer.

Reboot the computer and verify that the

router

address (www.routerlogin.net) is listed by your computer

as the default gateway address.

•

You might be running login software that is no longer needed. If your ISP provided a program to log

you in to the Internet (such as WinPoET), you no longer need to run that software after installing your

router

.You might need to go to Internet Explorer and select

Tools > Internet Options

, click the

Connections

tab, and select the

Never dial a connection

. Other browsers provide similar options.

Changes Are Not Saved

If the

router

does not save the changes that you make in the

router

interface, do the following:

•

When entering configuration settings, always click the

Apply

button before moving to another screen

or tab, or your changes are lost.

•

Click the

Refresh

or

Reload

button in the web browser. It is possible that the changes occurred, but

the old settings might be in the web browser’s cache.

Troubleshoot Wireless Connectivity

If you are experiencing trouble connecting wirelessly to the

router

, try to isolate the problem:

•

Does the wireless device or computer that you are using find your wireless network?

If not, check the WiFi LED on the front of the

router

. If it is off, you can press the

WiFi On/Off

button

on the

router

to turn the

router

wireless radios back on.

If you disabled the

router

’s SSID broadcast, then your wireless network is hidden and does not display

in your wireless client’s scanning list. (By default, SSID broadcast is enabled.)

•

Does your wireless device support the security that you are using for your wireless network (WPA or

WPA2)?

•

If you want to view the wireless settings for the

router

, use an Ethernet cable to connect a computer

to a LAN port on the

router

. Then log in to the

router

, and select

BASIC > Wireless

.

Be sure to click the

Apply

button if you change settings.

Note

If your wireless device finds your network but the signal strength is weak, check these conditions:

•

Is your

router

too far from your computer or too close? Place your computer near the

router

but at

least 6 feet (1.8 meters) away and see whether the signal strength improves.

•

Are objects between the

router

and your computer blocking the wireless signal?

Troubleshoot Your Network Using the Ping Utility

Most network devices and routers contain a ping utility that sends an echo request packet to the designated

device. The device then responds with an echo reply.You can easily troubleshoot a network using the

ping utility in your computer or workstation.

Test the LAN Path to Your Router

You can ping the

router

from your computer to verify that the LAN path to your

router

is set up correctly.

To ping the

router

from a Windows computer:

1.

From the Windows toolbar, click the

Start

button and select

Run

.

2.

In the field provided, type ping followed by the IP address of the

router

, as in this example:

ping www.routerlogin.net

3.

Click the

OK

button.

You see a message like this one:

Pinging <IP address > with 32 bytes of data

If the path is working, you see this message:

Reply from < IP address >: bytes=32 time=NN ms TTL=xxx

If the path is not working, you see this message:

Request timed out

If the path is not functioning correctly, one of the following problems might be present:

•

Wrong physical connections

For a wired connection, make sure that the numbered LAN port LED is lit for the port to which you are

connected.

Check that the appropriate LEDs are on for your network devices. If your

router

and computer are

connected to a separate Ethernet switch, make sure that the link LEDs are lit for the switch ports that

are connected to your computer and

router

.

•

Wrong network configuration

Verify that the Ethernet card driver software and TCP/IP software are both installed and configured

on your computer.

Verify that the IP address for your

router

and your computer are correct and that the addresses are

on the same subnet.

Test the Path from Your Computer to a Remote Device

To test the path from your computer to a remote device.

1.

From the Windows toolbar, click the

Start

button and select

Run

.

2.

In the Windows Run window, type

ping -n 10

where

is the IP address of a remote device such as your ISP DNS server.

If the path is functioning correctly, messages display that are similar to those shown in

Test the LAN

Path to Your Router

on page 178.

3.

If you do not receive replies, check the following:

•

Check that IP address of your

router

is listed as the default gateway for your computer. If DHCP

assigns the IP configuration of your computers, this information is not visible in your computer

Network Control Panel. Verify that the IP address of the

router

is listed as the default gateway.

•

Check to see that the network address of your computer (the portion of the IP address specified

by the subnet mask) is different from the network address of the remote device.

•

Check that your cable or DSL modem is connected and functioning.

•

If your ISP assigned a host name to your computer, enter that host name as the account name

on the Internet Setup page.

•

Your ISP might be rejecting the Ethernet MAC addresses of all but one of your computers.

Many broadband ISPs restrict access by allowing traffic only from the MAC address of your broadband

modem. Some ISPs additionally restrict access to the MAC address of a single computer connected

to that modem. If your ISP does this, configure your

router

to “clone” or “spoof” the MAC address from

the authorized computer.
