Make sure that the network settings of the computer are correct:

1.

Verify that your LAN-connected computers are configured to obtain an IP address

automatically through DHCP. For help with this, see the documentation for your computer or

“Related Documents” on page 39

.

2.

Verify whether the MAC address is needed. Some cable modem services require you to use

the MAC address of the computer registered on the account. If this is the case, in the Router

MAC Address section of the Basic Settings screen, select

Use this Computer’s MAC

Address

. To save your settings, click

Apply

. Restart the network in the correct sequence.

Check the router status lights to verify correct router operation:

If the Power light does not turn solid green within 2 minutes after you turn the router on, reset the

router according to the instructions in

“Restoring the Default Password and Configuration

Settings” on page 38

.

Checking Basic Router Functions

After you turn on power to the router, check that the following sequence of events has occurred:

1.

When power is first applied, verify that the Power light is on and that it is solid amber while

the router boots up (see

“Front Panel” on page 3

for an illustration).

2.

Verify that the Power light turns amber within a few seconds, indicating that the self-test

procedure is running.

3.

After approximately 90 seconds, verify that:

a.

The color of the Power light changes to green.

b.

The LAN port lights are lit for any local ports that are connected.

If a port’s light is lit, a link has been established to the connected device. If a LAN port is

connected to a 1 Gbps device, verify that the port’s light is green. If the port is 10/100

Mbps, the light will be amber.

c.

The Internet port is connected and its light is lit.

4.

Verify that the WPS button light on the front panel is blinking when you push it.

. Make sure that Caps Lock is off when you enter this

information.

•

Typically, your computer’s address should be in the range of 192.168.1.2 to 192.168.1.254.

Refer to your computer’s documentation for help with finding your computer’s IP address.

Internet light stays

amber.

When the router is turned on, the Internet light turns amber for about 70 seconds

and then turns green. If the light does not turn green, the router has a problem.

If the Internet light is still amber 2 minutes after turning on power to the router:

1.

The Internet is not accessible. Confirm that you have the correct internet

setting.

2.

Clear the router’s configuration to factory defaults. This will set the router’s

IP address to 192.168.1.1. This procedure is explained in

“Restoring the

Default Password and Configuration Settings” on page 38

.

3.

Turn the power off and back on to see if the router recovers.

Internet or LAN port lights

are off.

If either the LAN or Internet lights do not light when the Ethernet connection is

made, check the following:

1.

Make sure that the Ethernet cable connections are secure at the router and

at the computer.

2.

Make sure that power is turned on to the connected computer.

3.

Be sure you are using Ethernet cables like the cable that was supplied with

the N600 wireless gigabit router.

See

“Connecting Your N600 Wireless Gigabit Router” on page 11

for

instructions.

If your computer’s IP address is 169.254.x.x, verify that you have a good

connection from the computer to the router, and then restart your computer.

Checking the Internet Service Connection

If your router is unable to access the Internet, check that the Internet connection is working, and

then check that the N600 wireless gigabit router can get an Internet address.

Check that the Internet connection is working:

1.

Internet connection

. First verify that your cable or ADSL modem has a successful

connection. The cable or ADSL modem status lights indicate if the modem connection is

successful or not. Check your modem documentation, or call your Internet Service Provider

for help with verifying that the modem has a successful connection.

2.

Wireless router Internet light is green

. If your Internet light is solid green, then you have a

good Internet connection, and your wiring is correct.

3.

Wireless router Internet light is solid amber

. If your Internet light is solid amber, then your

N600 wireless gigabit router is attempting to make an Internet connection with the service

provider. The light should turn green within several minutes. If it does not, check the Internet

connection on the modem.

4.

Wireless router Internet light

off

. If the Internet light is off, verify that the Ethernet cable is

securely connected between the cable or ADSL modem, and that both the modem and N600

wireless gigabit router are turned on.

Obtaining an Internet IP Address

If your N600 wireless gigabit router is unable to access the Internet, and your Internet light is

amber, check the N600 wireless gigabit router to see if it is able to get an Internet IP address from

your service provider. Unless you have a static IP address, your N600 wireless gigabit router

automatically requests an IP address from your service provider.

To check the Internet IP address from the browser interface:

1.

Log in to the N600 wireless gigabit router.

2.

Select

Router Status

under Maintenance on the main menu to check that an IP address is

shown for the Internet port. If 0.0.0.0 is shown, your N600 wireless gigabit router has not

obtained an IP address from your service provider.

Troubleshooting

31

If your router is unable to obtain an IP address from the your service provider, the problem might

be one of the following:

•

Your service provider might require a login. Ask your service provider whether they require

PPP over Ethernet (PPPoE) login.

•

The service name, user name, and password might be set incorrectly. See

“Troubleshooting

PPPoE”

.

•

Your service provider might check for your computer’s host name.

Assign the computer host name of your ISP account to the N600 wireless gigabit router in the

Basic Settings screen.

•

Your service provider allows only one Ethernet MAC address to connect to Internet, and

might check for your computer’s MAC address. In this case, do one of the following:

–

Inform your service provider that you have bought a new network device, and ask them to

use the N600 wireless gigabit router’s MAC address.

–

Configure your router to spoof your computer’s MAC address. This can be done in the

Basic Settings screen. Refer to the online help, which you can access from the N600

wireless gigabit router main menu.

Troubleshooting PPPoE

To troubleshoot a PPPoE connection:

1.

Log in to the N600 wireless gigabit router.

2.

Select

Router Status

under Maintenance on the main menu.

3.

Click the

Connection Status

button.

4.

If all the steps indicate OK, then your PPPoE connection is up and working.

5.

If any of the steps indicate Failed, you can attempt to reconnect by clicking

Connect

. The

N600 wireless gigabit router will continue to attempt to connect indefinitely.

If you cannot connect after several minutes, you might be using an incorrect service name,

user name, or password. There also might be a provisioning problem with your ISP.

Unless you connect manually, the N600 wireless gigabit router will not

authenticate using PPPoE until data is transmitted to the network.
