NETGEAR DOCSIS 3.0 N900 Wireless Data Gateway 

If the path is functioning correctly, replies as in the previous section are displayed. If, you do 
not receive replies:

•

Check that your computer has the IP address of your gateway listed as the default 
gateway. If DHCP assigns the IP configuration of your computer, this information is not 
visible in your computer’s Network Control Panel. Verify that the IP address of the 
gateway is listed as the default gateway.

•

Check to see that the network address of your computer (the portion of the IP address 
specified by the netmask) is different from the network address of the remote device.

•

Check that your Internet LED is on.
