  Chapter 9.  Troubleshooting     |   147N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700 User Manual Internet LED Is RedIf the Internet LED is red, the device could not connect to the Internet. Verify the following:•Check that your log-in credentials are correct. See Log In to the N600 Modem Router onpage 24 for more information.•Check that the information you entered on the Basic Settings screen is correct. See Manual Setup (Basic Settings) on page 28.•Check with your ISP to verify that the multiplexing method, VPI, and VCI settings on the ADSL settings screen are correct.•Find out if the ISP is having a problem. If it is, wait until that problem is cleared up and try again.Cannot Obtain an Internet IP AddressIf your wireless modem router cannot access the Internet, and your Internet LED is green or blinking green, check whether the wireless modem router can obtain an Internet IP address from the ISP. Unless you have been assigned a static IP address, your wireless modem router must request an IP address from the ISP. You can determine whether the request was successful as follows:1. Access the router menus at http://192.168.0.1 and log in.2. Under Maintenance, select Router Status and check that an IP address shows for the WAN port. If 0.0.0.0 shows, your wireless modem router has not obtained an IP address from your ISP.If your router cannot 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 incorrect. See Debug PPPoE or PPPoA on page 148.•Your ISP might check for your computer’s host name. Assign the computer host name of your ISP account to the wireless modem router in the browser-based Setup Wizard. See Setup Wizard on page 27 for more information.•Your ISP allows only one Ethernet MAC address to connect to the 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 through the Basic Settings screen. See Manual Setup (Basic Settings) on page 28.
148 |   Chapter 9.  Troubleshooting N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700 User Manual Debug PPPoE or PPPoADebug the PPPoE or PPPoA connection as follows:1. Access the router menus at http://192.168.0.1 and log in.2. Under Maintenance, select Router Status.3. Click the Connection Status button.4. If all of the steps indicate OK, your PPPoE or PPPoA connection is working.5. If any of the steps indicate Failed, you can attempt to reconnect by clicking Connect.The wireless modem router continues to attempt to connect indefinitely. If you do not connect after several minutes, check that the service name, user name, and password you are using are correct. Also check with your ISP to be sure that there is no problem with their service.Note: Unless you connect manually, the wireless modem router does not authenticate with PPPoE or PPPoA until data is transmitted to the network.Cannot Load an Internet Web PageIf your wireless modem router can obtain an IP address, but your browser cannot load any Internet Web pages:•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 wireless modem router’s configuration, reboot your computer, and verify the DNS address. Alternately, you can configure your computer manually with DNS addresses, as explained in your operating system documentation.•Your computer might not have the wireless modem router configured as its TCP/IP wireless modem router.If your computer obtains its information from the wireless modem router by DHCP, reboot the computer, and verify the wireless modem router address.TCP/IP Network Not RespondingMost TCP/IP terminal devices and routers have a ping utility for sending an echo request packet to the designated device. The device responds with an echo reply to tell whether a TCP/IP network is responding to requests.

  Appendix B.  NETGEAR VPN Configuration     |   161N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700 User Manual Using a Fully Qualified Domain Name (FQDN)Many ISPs provide connectivity to their customers using dynamic instead of static IP addressing. This means that a user’s IP address does not remain constant over time, which presents a challenge for gateways attempting to establish VPN connectivity.A Dynamic DNS (DDNS) service allows a user whose public IP address is dynamically assigned to be located by a host or domain name. It provides a central public database where information (such as email addresses, host names, and IP addresses) can be stored and retrieved. Now, a gateway can be configured to use a third-party service instead of a permanent and unchanging IP address to establish bidirectional VPN connectivity.To use DDNS, you must register with a DDNS service provider. Some DDNS service providers include:•DynDNS: www.dyndns.org•TZO.com: netgear.tzo.com•ngDDNS: ngddns.iego.netIn this example, Gateway A is configured using a sample FQDN provided by a DDNS service provider. In this case we established the hostname dgnd3300v2.dyndns.org for Gateway A using the DynDNS service. Gateway B uses the DDNS service provider when establishing a VPN tunnel. To establish VPN connectivity, Gateway A must be configured to use Dynamic DNS, and Gateway B must be configured to use a DNS host name provided by a DDNS service provider to find Gateway A. Again, the following step-by-step procedures assume that you have already registered with a DDNS service provider and have the configuration information necessary to set up the gateways.Step-by-Step Configuration1. Log in to Gateway A (your wireless modem router) as described in Log In to the N600 Modem Router on page 24.This example assumes that you have set the local LAN address as 10.5.6.1 for Gateway A and have set your own password.2.
