7-7 Troubleshooting
v1.0, November 2009
5. If any of the steps indicates Failed, you can attempt to reconnect by clicking Connect. The
modem router will continue to attempt to connect indefinitely.
If you cannot connect after several minutes, you might be using an incorrect service name, user
name, or password. There also might be a provisioning problem with your ISP.
Troubleshooting Internet Browsing
If your modem router can obtain an IP address, but your computer is unable to load any Web pages
from the Internet:
• Your computer might not recognize any DNS server addresses.
A DNS server is a host on the Internet that translates Internet names (such as www addresses)
to numeric IP addresses. Typically your ISP provides the addresses of one or two DNS servers
for your use. If you entered a DNS address during the modem router’s configuration, reboot
your computer, and verify the DNS address as described in the online document that you can
access from “Preparing Your Network” in Appendix B. Alternatively, you can configure your
computer manually with DNS addresses, as explained in your operating system
documentation.
• Your computer might not have the modem router configured as its TCP/IP modem router.
If your computer obtains its information from the modem router by DHCP, reboot the
computer, and verify the modem router address as described in the online document that you
can access from “Preparing Your Network” in Appendix B.
Resolving a ‘Reload Firmware’ Message
When you attempt to connect to the Internet, Windows may display a message that you must
reload the router’s firmware. If this situation occurs, a problem has been detected with the router’s
firmware.
To recover the firmware:
1. If you already have the firmware file on your PC, go directly to step 2. If you do not have the
firmware file on your PC, obtain the firmware from the NETGEAR support site at
http://www.netgear.com/support.
2. Click Browse.
Note: Unless you connect manually, the modem router will not authenticate using PPPoE
or PPPoA until data is transmitted to the network.
