N750 Wireless Dual Band Gigabit Router WNDR4300

Troubleshooting

• 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.

LEDs Never Turn Off

When the router is turned on, the LEDs light 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 lit 1 minute after power-up:

• Cycle the power to see if the router recovers.

• Press and hold the Restore Factory Settings button to return the router to its factory

settings as explained in Factory Settings on page 123.

If the error persists, you might have a hardware problem and should contact technical support at

www.netgear.com/support.

Internet LED Is Off

If the Internet LED does not light, check the following:

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

computer.

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

• Be sure that you are using the correct cable.

When connecting the router’s Internet port to a cable or DSL modem, use the cable that was

supplied with the cable or DSL modem. This cable could be a standard straight-through

Ethernet cable or an Ethernet crossover cable.

2.4 GHz and 5 GHz LEDs Are Off

If these LEDs stay off, check to see if the Wi-Fi On/Off button on the router has been pressed.

This button turns the wireless radios in the router on and off. The 2.4 GHz and 5 GHz LEDs are

lit when the wireless radios are turned on.

Cannot Log In to the Router

If you are unable to log in to the router from a computer on your local network, check the

following:

• If you are using an Ethernet-connected computer, check the Ethernet connection between

the computer and the router as described in the previous section.
