Cannot Access the Internet
If you can access your router but you are unable to access the Internet, first determine
whether the router can obtain an IP address from your Internet Service Provider (ISP).
Unless your ISP provides a fixed IP address, your router must request 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
http://www.netgear.com
.
2.
.
3.
Select Maintenance > 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
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 they require 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 Basic
Settings 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.
