.
Internet or Ethernet Port LEDs Are Off
If either the Ethernet port LEDs or the Internet LED does not light when the Ethernet connection is
made, check the following:
•
Make sure that the Ethernet cable connections are secure at the router and at the modem or computer.
•
Make sure that power is turned on to the connected modem or computer.
•
Be sure that you are using the correct cable.
When you connect the router’s Internet port to a modem, use the cable that was supplied with the modem. This
cable can be a standard straight-through Ethernet cable or an Ethernet crossover cable.
WiFi LED Is Off
If the WiFi LED stays off, check to see if someone pressed the
WiFi On/Off
button on the router. This button turns
the WiFi radios in the router on and off. The WiFi LED is lit when the WiFi radios are turned on.
You Cannot Log In to the Router
If you are unable to log in to the router from a computer on your local network, check the following:
•
If you are using an Ethernet-connected computer, check the Ethernet connection between the computer and
the router.
•
Make sure that the IP address of your computer is on the same subnet as the router. If you are using the
recommended addressing scheme, your computer’s address is in the range of 192.168.1.2 to 192.168.1.254.
•
If your computer’s IP address is shown as 169.254.x.x, recent versions of Windows and Mac OS generate and
assign an IP address if the computer cannot reach a DHCP server. These autogenerated addresses are in the
range of 169.254.x.x. If your IP address is in this range, check the connection from the computer to the router,
and reboot your computer.
•
If your router’s IP address was changed and you do not know the current IP address, clear the router’s
configuration to factory defaults. This sets the router’s IP address to 192.168.1.1. For more information, see
Factory Settings
on page 158.

Make sure that you are using the correct login information. The user name is
admin
, and the default 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.
You Cannot Access the Internet
If you can access your 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 ADVANCED Home page.
To check the WAN IP address:
1.
Launch a web browser from a computer or WiFi device that is connected to the network.
2.
Select an external site such as
netgear.com
.
3.
Type
.
A login window opens.
4.
Enter the router user name and password.
The user name is
admin
.The default password is
password
.The user name and password are case-sensitive.
The BASIC Home page displays.
5.
Click the
ADVANCED
tab.
The ADVANCED Home page displays.
6.
Check to see that an IP address is shown for the Internet port. If 0.0.0.0 is shown, your router did not obtain 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. For more information, see
Sequence to Restart Your Network
on page 149.
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 on the Internet Setup page.
•
If your ISP allows only one Ethernet MAC address to connect to Internet and checks for your computer’s MAC
address, do one of the following:
Troubleshooting

•
Inform your ISP that you 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 obtained an IP address, but your computer is does not load any web pages from the Internet, it might be
for one or more of the following reasons:
•
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.
•
The router might not be configured as the TCP/IP gateway on your computer.
If your computer obtains its information from the router by DHCP, reboot the computer and verify the gateway
address.
•
You might be running login software that is no longer needed.
If your ISP provided a program to log you in to the Internet (such as WinPoET), you no longer need to run that
software after installing your router.You might need to go to Internet Explorer and select
Tools > Internet Options
,
click the
Connections
tab, and select
Never dial a connection
. Other browsers provide similar options.
Troubleshoot Internet Browsing
If your router can obtain an IP address but your computer is unable to load any web pages from the Internet, check
the following:
•
The traffic meter is enabled, and the limit was reached.
By configuring the traffic meter not to block Internet access when the traffic limit is reached, you can resume
Internet access. If your ISP sets a usage limit, they might charge you for the overage.
•
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, restart your computer.
Alternatively, you can configure your computer manually with a DNS address, as explained in the documentation
for your computer.
•
The router might not be configured as the default gateway on your computer.
Reboot the computer and verify that the router address (www.routerlogin.net) is listed by your computer as the
default gateway address.
•
You might be running login software that is no longer needed. If your ISP provided a program to log you in to
the Internet (such as WinPoET), you no longer need to run that software after installing your router.You might
need to go to Internet Explorer and select
Tools > Internet Options
, click the
Connections
tab, and select the
Never dial a connection
. Other browsers provide similar options.

Changes Are Not Saved
If the router does not save the changes that you make on the routerweb pages, do the following:
•
When entering configuration settings, always click the
Apply
button before moving to another page or tab, or
your changes are lost.
•
Click the
Refresh
or
Reload
button in the web browser. It is possible that the changes occurred, but the old
settings might be in the web browser’s cache.
Troubleshoot WiFi Connectivity
If you are experiencing trouble connecting over WiFi to the router, try to isolate the problem:
•
Does the WiFi device or computer that you are using find your WiFi network?
If not, check the WiFi LED on the front of the router. If it is off, you can press the
WiFi On/Off
button on the
router to turn the router WiFi radios back on.
If you disabled the router’s SSID broadcast, then your WiFi network is hidden and does not display in your WiFi
client’s scanning list. (By default, SSID broadcast is enabled.)
•
Does your WiFi device support the security that you are using for your WiFi network (WPA or WPA2)?
•
If you want to view the WiFi settings for the router, use an Ethernet cable to connect a computer to a LAN port
on the router. Then log in to the router, and select
BASIC > Wireless
.
Be sure to click the
Apply
button if you change settings.
Note
If your WiFi device finds your network but the signal strength is weak, check these conditions:
•
Is your router too far from your computer or too close? Place your computer near the router but at least 6 feet
(1.8 meters) away and see whether the signal strength improves.
•
Are objects between the router and your computer blocking the WiFi signal?
Troubleshoot Your Network Using the Ping Utility
Most network devices and routers contain a ping utility that sends an echo request packet to the designated device.
The device then responds with an echo reply.You can easily troubleshoot a network using the ping utility in your
computer or workstation.
Test the LAN Path to Your Router
You can ping the router from your computer to verify that the LAN path to your router is set up correctly.
To ping the router from a Windows computer:
1.
From the Windows toolbar, click the
Start
button and select
Run
.
2.
In the field provided, type
ping
followed by the IP address of the router, as in this example:
Troubleshooting

3.
Click the
OK
button.
You see a message like this one:
Pinging <IP address > with 32 bytes of data
If the path is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
If the path is not working, you see this message:
Request timed out
If the path is not functioning correctly, one of the following problems might be present:
•
Wrong physical connections
For a wired connection, make sure that the numbered LAN port LED is lit for the port to which you are connected.
Check that the appropriate LEDs are lit for your network devices. If your router and computer are connected to
a separate Ethernet switch, make sure that the link LEDs are lit for the switch ports that are connected to your
computer and router.
•
Wrong network configuration
Verify that the Ethernet card driver software and TCP/IP software are both installed and configured on your
computer.
Verify that the IP address for your router and your computer are correct and that the addresses are on the same
subnet.
Test the Path From Your Computer to a Remote Device
To test the path from your computer to a remote device:
1.
From the Windows toolbar, click the
Start
button and select
Run
.
2.
In the Windows Run window, type
ping -n 10
<IP address>
where
<IP address>
is the IP address of a remote device such as your ISP DNS server.
If the path is functioning correctly, messages display that are similar to those shown in
