Ensure that both the computer and the Gateway are plugged into power. 

Make sure the wireless settings in the computer and Gateway match  

 

For a computer connected via wireless, the wireless network name (SSID) and WPA security 
settings for the Gateway and wireless computer must match exactly.  

 

If you have enabled the Gateway to restrict wireless access by the specific MAC address, you 
must remove the wireless computer’s MAC address from the MAC Filtering section. 

Make sure the network settings of the computer are correct 

Wired and computers connected via wireless must have network (IP) addresses on the same 
network as the Gateway. The simplest way to do this is to configure each computer to obtain an IP 
address automatically using DHCP. Refer to the DHCP documentation that came with your 
computer. 

The Power light is not ON or is blinking 

If the Power and other lights are off when your unit is turned on: 

 

Make sure that the power cord is properly connected and that the power adapter is properly 
connected to a functioning power outlet.  

 

Check that you are using the power adapter that NETGEAR supplied for this product. 

 

Ensure that the power switch located on the back of your Gateway is in the ON position. 

The Wireless or Ethernet port lights are not on 

If neither the Ethernet port lights nor the wireless light come on when the Ethernet connection is 
made, check the following: 

 

Make sure that the Ethernet cable connections (1, 2, 3, and 4) are secure at the computer and 
at the Gateway. 

 

Make sure that connected computer’s power is turned ON. 

 

Press the wireless button on the front of the Gateway to turn the Wireless light on.
