Troubleshooting the ISP Connection

If your firewall is unable to access the Internet, you should first determine whether the firewall is
able to obtain a WAN IP address from the ISP. Unless you have been assigned a static IP address,
your firewall must request an IP address from the ISP. You can determine whether the request was
successful using the Web Configuration Manager.
To check the WAN IP address:
1. Launch your browser and navigate to an external site such as www.netgear.com
2. Access the Main Menu of the firewall's configuration at https://192.168.1.1
3. Under the Monitoring menu, click Router Status.
4. Check that an IP address is shown for the WAN Port.
If 0.0.0.0 is shown, your firewall has not obtained an IP address from your ISP.
If your firewall is unable to obtain an IP address from the ISP, you may need to force your cable or
DSL modem to recognize your new firewall by performing the following procedure:
1. Turn off power to the cable or DSL modem.
2. Turn off power to your firewall.
3. Wait five minutes and reapply power to the cable or DSL modem.
4. When the modem's LEDs indicate that it has reacquired sync with the ISP, reapply power to
your firewall.
If your firewall is still unable to obtain an IP address from the ISP, the problem may be one of the
following:
• Your ISP may require a login program.
Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of login.
• If your ISP requires a login, you may have incorrectly set the login name and password.
• Your ISP may check for your PC's host name.
Assign the PC Host Name of your ISP account as the Account Name in the Basic Settings
menu.
• Your ISP only allows one Ethernet MAC address to connect to the Internet, and may check for
your PC's MAC address. In this case:
– Inform your ISP that you have bought a new network device, and ask them to use the
firewall's MAC address; or
