N600 Wireless Dual Band Gigabit Router Premium Edition WNDR3800

• Wired and wirelessly connected computers need to have network (IP) addresses on the

same network as the router. The simplest way to do this is to configure each computer to

obtain an IP address automatically using DHCP.

• Some

cable modem service providers require you to use the MAC address of the

computer initially registered on the account. You can view the MAC address in the

Attached Devices screen.

Troubleshooting with the LEDs

After you turn on power to the router, the following sequence of events should occur:

1. W

hen power is first applied, verify that the Power LED is on.

2. Af

ter approximately 2 minutes, verify that:

• The Power

LED is solid green.

• The

Internet LED is on.

• The Eth

ernet LAN LED is on if any local port is connected to a computer. This

indicates that a link has been established to the connected device.

The LEDs on the front panel of the router can be used for troubleshooting.

Power LED Is Off or Blinking

• Make sure that the power cord is securely connected to your router and that the power

adapter is securely connected to a functioning power outlet.

• Check that

you are using the 12V DC, 2.5A power adapter that NETGEAR supplied for

this product.

• If the

Power LED blinks green every second, the router software is corrupted. This can

happen if a firmware upgrade is interrupted, or if the router detects a problem with the

firmware. If the error persists, you have a hardware problem. For recovery instructions, or

help with a hardware problem, contact Technical Support at www.netgear.com/support.

LEDs Never Turn Off

When the router is turned on, the LEDs turn on for about 10 seconds and then turn off. If all

the LEDs stay on, there is a fault within the router.

If all LEDs are still on 1 minute after power-up:

• Cycle the

power to see if the router recovers.

• Clear t

he router’s configuration to factory defaults, as explained in Factory Default

Settings on p

age 119.

If the error persists, you might have a hardware problem and should contact Technical

pport at www.netgear.com/support.
