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. When power is first applied, verify that the Power LED is on. 2. Verify that the Power LED turns amber within a few seconds, indicating that the self-test is running. 3. After 2 minutes, verify the following: • The Power LED lights solid green. • The Internet LED lights. • The Wireless LED lights blue. 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, 5A power adapter that NETGEAR supplied for this product. • If the Power LED blinks slowly and continuously, the router firmware 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. Power LED Stays Amber When the router is turned on, the Power LED turns amber for about 20 seconds and then turns green. If the LED does not turn green, the router has a problem.
