7-6 Troubleshooting
v1.0, November 2009
• Check if your ISP has a problem—it may not be the router that cannot connect to the Internet
but your ISP that cannot provide an Internet connection.
Obtaining an Internet IP Address
If your wireless-N modem router is unable to access the Internet, and your Internet LED is green
or blinking green, you should determine whether the wireless-N modem router is able to obtain an
Internet IP address from the ISP. Unless you have been assigned a static IP address, your wireless-
N modem router must request an IP address from the ISP. You can determine whether the request
was successful using the browser interface.
To check the Internet IP address from the browser interface:
1. Launch your browser, and select an external site such as www.netgear.com.
2. Access the main menu of the wireless-N modem router’s configuration at http://192.168.0.1.
3. In the main menu, under Maintenance, click Router Status and check that an IP address is
shown for the WAN port. If 0.0.0.0 is shown, your wireless-N modem router has not obtained
an IP address from your ISP.
If your router is unable to obtain an IP address from the ISP, the problem might be one of the
following:
• If you have selected a login program, the service name, user name, or password might be
incorrectly set. See the following section, “Troubleshooting PPPoE or PPPoA.
• Your ISP might check for your computer’s host name.
Assign the computer host name of your ISP account to the wireless-N modem router in the
browser-based Setup Wizard.
• Your ISP allows only one Ethernet MAC address to connect to Internet, and might check for
your computer’s MAC address. In this case, do one of the following:
– Inform your ISP that you have bought a new network device, and ask them to use the
router’s MAC address.
– Configure your router to spoof your computer’s MAC address. This can be done in the
Basic Settings screen. See the .
Troubleshooting PPPoE or PPPoA
The PPPoE or PPPoA connection can be debugged as follows:
1. Access the main menu of the router at http://192.168.0.1.
2. Under Maintenance, select Router Status.
