Troubleshoot the ISP Connection

If your wireless VPN firewall is unable to access the Internet, you should first determine
whether the wireless VPN firewall is able to obtain a WAN IP address from the ISP. Unless
you have been assigned a static IP address, your wireless VPN firewall requests an IP
address from the ISP. You can determine whether the request was successful using the web
management interface.

To check the WAN IP address:
1. Launch your browser and navigate to an external site such as www.netgear.com.
2. Access the web management interface of the wireless VPN firewall's configuration at
https://192.168.1.1.
3. Select Network Configuration > WAN Settings > Broadband ISP Settings. The
Broadband ISP Settings screen for IPv4 displays.
4. Take one of the following actions:
- For IPv4. Click the Broadband Status option arrow. The Connection Status pop-up
screen for IPv4 displays (see
- For IPv6. In the upper right of the screen, select the IPv6 radio button. The ISP
Broadband Settings screen displays the IPv6 settings. Then click the Status option
arrow. The Connection Status pop-up screen for IPv6 displays (see
page 41).
5. Check that an IP address is shown for the WAN port. If an IP address with zeros only is
shown, or if no IP address is shown, the wireless VPN firewall has not obtained an IP
address from your ISP, or for IPv6, has not obtained or generated an IP address.

If your wireless VPN firewall is unable to obtain an IP address from the ISP, you might
need to force your modem, dish, or router to recognize your new wireless VPN firewall
by performing the following procedure:
1. Turn off the power to the modem, dish, or router.
2. Turn off the power to your wireless VPN firewall.
3. Wait 5 minutes, and then turn on the power to the modem, dish, or router.
4. When the LEDs of the modem, dish, or router indicate that synchronization with the ISP has
occurred, turn on the power to your wireless VPN firewall.
If your wireless VPN firewall is still unable to obtain an IP address from the ISP, the problem
might be one of the following:
• Your ISP might require a login program.
For IPv4 connections, ask your ISP whether they require PPP over Ethernet (PPPoE) or
some other type of login.
• For IPv4 connections, if your ISP requires a login, you might have incorrectly set the login
name and password.
• For IPv4 connections, your ISP might check for your computer's host name. On the
Broadband ISP Settings screen for IPv4, in the Account Name field, enter the host name,
