Network Settings
Make sure that the network settings of the computer are correct:
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. When power is first applied, verify that the Power LED
is on.
2. V
erify 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.
If the Power LED is still amber 1 minute after you turn on power to the router:
1. T
urn off the power and then turn it back on to see if the router recovers.
2. Press and hold the Reset button to return the router to
its factory settings. as explained
in Restore the Factory Settings and Password on page 136.
