D6300 WiFi DSL Modem Router
Quick Tips
This section describes tips for troubleshooting some common problems.
Sequence to Restart Your Network
Be sure to restart your network in this sequence:
1.
Turn off
and
unplug the modem.
2.
Turn off the WiFi modem router and computers.
3.
Plug in the modem and turn it on. Wait 2 minutes.
4.
Turn on the WiFi modem router and wait 2 minutes.
5.
Turn on the computers.
Check Ethernet Cable Connections
Make sure that the Ethernet cables are securely plugged in.
•
The Internet status LED on the WiFi modem router is lit if the Ethernet cable connecting
the WiFi modem router and the modem is plugged in securely and the modem and WiFi
modem router are turned on.
•
For each powered-on computer connected to the WiFi modem router by an Ethernet
cable, the corresponding numbered router LAN port LED is lit.
Wireless Settings
Make sure that the wireless settings in the computer and WiFi modem router match exactly.
•
For a wirelessly connected computer, the wireless network name (SSID) and wireless
security settings of the WiFi modem router and wireless computer need to match exactly.
•
If you set up an access list in the Advanced Wireless Settings screen, you have to add
each wireless computer’s MAC address to the WiFi modem router’s access list.
Network Settings
Make sure that the network settings of the computer are correct.
•
Wired and wirelessly connected computers need to have network (IP) addresses on the
same network as the WiFi modem router. The simplest way to achieve this address
commonality is to configure each computer to obtain an IP address automatically using
DHCP.
•
Some cable modem service providers require you to use the MAC address of the
computer initially registered on the account. You can view the MAC address in the
Attached Devices screen.

Troubleshoot with the LEDs
After you turn on power to the WiFi modem router, the following sequence of events should
occur:
1.
When power is first applied, verify that the Power LED is lit.
2.
Verify that the Power LED turns red within a few seconds, indicating that the self-test is
running.
3.
After approximately 30 seconds, verify that:
•
The Power LED is solid green.
•
The Internet LED is lit.
•
The Ethernet LED is lit for any local port that is connected to a computer. This LED
indicates that a link has been established to the connected device.
The LEDs on the front panel of the WiFi modem router can be used for troubleshooting.
Power LED Is Off or Blinking
•
Make sure that the power cord is securely connected to your WiFi modem router and that
the power adapter is securely connected to a functioning power outlet.
•
Check that you are using the 12V DC, 5A power adapter that NETGEAR supplied for this
product.
•
If the Power LED blinks slowly and continuously, the WiFi modem router firmware is
corrupted. This situation can happen if a firmware upgrade is interrupted, or if the WiFi
modem router detects a problem with the firmware. If the error persists, you have a
hardware problem. For recovery instructions, or help with a hardware problem, contact
technical support at
www.netgear.com/support
.
Power LED Stays Red
When the WiFi modem router is turned on, the Power LED turns red for about 20 seconds
and then turns green. If the LED does not turn green, the WiFi modem router has a problem.
If the Power LED is still red one minute after you turn on power to the WiFi modem router:
1.
Turn the power off and back on to see if the WiFi modem router recovers.
2.
Press and hold the
Restore Factory Settings
button to return the WiFi modem router to
its factory settings. See

.
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 WiFi modem 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 connecting the WiFi modem router’s Internet port to a cable or DSL modem, use
the cable that was supplied with the cable or DSL modem. This cable could be a standard
straight-through Ethernet cable or an Ethernet crossover cable.
Wireless LEDs Are Off
If the Wireless LEDs stay off, check to see if the Wireless On/Off button on the WiFi modem
router has been pressed. This button turns the wireless radios in the WiFi modem router on
and off. The Wireless LEDs are lit when the wireless radio is turned on.
The Push 'N' Connect (WPS) Button Blinks Green
If after you press the WPS button and the button blinks green, check the following:
•
Make sure that you are using the button and not the WiFi modem router’s built-in
registrar.
•
Check that PIN verification has succeeded for the wireless device you are adding to the
wireless network.
•
Make sure that you have not pressed the WPS button on the top of the WiFi modem
router after disabling the WPS feature (you logged in to the WiFi modem router and
disabled this feature previously).
•
Check that the WiFi modem router is not in the temporary AP setup locked state (if you
are using the wireless repeater function).

Cannot Log In to the Router
If you are unable to log in to the WiFi modem 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 WiFi modem router as described in the previous section.
•
Make sure that your computer’s IP address is on the same subnet as the WiFi modem
router. If you are using the recommended addressing scheme, your computer’s address
should be in the range of 192.168.0.2 to 192.168.0.254.
•
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 WiFi modem router, and reboot
your computer.
•
If your WiFi modem router’s IP address was changed and you do not know the current IP
address, clear the WiFi modem router’s configuration to factory defaults. This procedure
sets the WiFi modem router’s IP address to 192.168.0.1. This procedure is explained in
Factory Settings
on page 131.
•
Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using
Internet Explorer, click
Refresh
to be sure that the Java applet is loaded.
•
Try quitting the browser and launching it again.
•
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 WiFi modem router as an additional router
behind an existing router in your network, consider replacing the existing router instead.
NETGEAR does not support such a configuration.
•
If you are attempting to set up your NETGEAR WiFi modem router as a replacement for
an ADSL gateway in your network, the WiFi modem router cannot perform many gateway
services, for example, converting ADSL or cable data into Ethernet networking
information. NETGEAR does not support such a configuration.
Cannot Access the Internet
If you can access your router but you are unable to access the Internet, first determine
whether the WiFi modem router can obtain an IP address from your Internet service provider
(ISP). Unless your ISP provides a fixed IP address, your WiFi modem 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
.

2.
Access the WiFi modem router interface at
.
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 WiFi
modem router has not obtained an IP address from your ISP.
If your WiFi modem router cannot obtain an IP address from the ISP, you might need to force
your cable or DSL modem to recognize your new WiFi modem router by restarting your
network, as described in
Sequence to Restart Your Network
on page 121.
If your WiFi modem 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 Internet
Basic Settings screen.
•
Your ISP allows only one Ethernet MAC address to connect to the 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
WiFi modem router’s MAC address.
-
Configure your WiFi modem router to clone your computer’s MAC address.
If your WiFi modem 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 WiFi modem
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 WiFi modem router configured as its TCP/IP gateway.
If your computer obtains its information from the WiFi modem 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 WiFi modem router. You might need
to go to Internet Explorer and select
Tools > Internet Options
, click the
Connections
tab, and select
Never dial a connection
