• Make sure that you are using the correct login information. The factory default login name
is admin and the password is password. Make sure that Caps Lock is off when you enter
this information.
• If you are attempting to set up your NETGEAR router as a replacement for an ADSL
gateway in your network, the router cannot perform many gateway services. For
example, the router cannot convert ADSL or cable data into Ethernet networking
information. NETGEAR does not support such a configuration.
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.
