N750 Wireless Dual Band Gigabit Router WNDR4300

Cannot Access the Internet

If you can access WNDR4300 router but not the Internet, check to see if the router can obtain

an IP address from your Internet service provider (ISP). Unless your ISP provides a fixed IP

address, your router requests an IP address from the ISP. You can determine whether the

request was successful using the Router Status screen.

 To check the WAN IP address:

1. Start your browser, and select an external site such as www.netgear.com.

2. Access the router interface at www.routerlogin.net.

3. Select Administration > Router Status.

4. Check that an IP address is shown for the Internet port. If 0.0.0.0 is shown, your router has

not obtained an IP address from your ISP.

If your router cannot obtain an IP address from the ISP, you might need to force your cable or

DSL modem to recognize your new router by restarting your network, as described in

Sequence to Restart Your Network on page 116.

If your router is still unable to obtain an IP address from the ISP, the problem might be one of

the following:

• Your Internet service provider (ISP) might require a login program.

Ask your ISP whether it requires PPP over Ethernet (PPPoE) or some other type of login.

• If your ISP requires a login, the login name and password might be set incorrectly.

• Your ISP might check for your computer’s host name.

Assign the computer host name of your ISP account as the account name in the Internet

Setup screen.

• 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 clone your computer’s MAC address.

If your 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 router’s

configuration, reboot your computer, and verify the DNS address. You can configure your

computer manually with DNS addresses, as explained in your operating system

documentation.

• Your computer might not have the router configured as its TCP/IP gateway.
