LEDs Never Turn Off
When the WiFi DSL modem router is turned on, the LEDs light for about 10 seconds and then 
turn off. If all the LEDs stay lit, a fault exists within the WiFi DSL modem router.
If all LEDs are still lit 1 minute after power-up:
•Cycle the power to see if the WiFi DSL modem router recovers.
•Press and hold the Reset button to return the WiFi DSL modem router to its factory 
settings. See 
Factory Settings on page 150.
If the error persists, you might have a hardware problem and should contact technical 
support at 
www.netgear.com/support.
Internet or Ethernet Port LEDs Are Off
If the Internet LED or the Ethernet port LEDs do not light when the Ethernet connection is 
made, check the following:
•Make sure that the Ethernet cable connections are secure at the WiFi DSL 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 DSL 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 LED Is Off
If the Wireless LED stays off, check to see if the WiFi On/Off button on the WiFi DSL modem 
router has been pressed. This button turns the wireless radios in the WiFi DSL modem router 
on and off. The Wireless LEDs are lit when the wireless radio is turned on.
The Push N Connect (WPS) Button Does Not Work
If after you press the WPS button and the Wireless LED does not blink, check the following:
•Make sure that you are using the button and not the WiFi DSL 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 side of the WiFi DSL 
modem router after disabling the WPS feature (you logged in to the WiFi DSL modem 
router and disabled this feature previously).
•Check that the WiFi DSL 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 DSL 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 DSL modem router. For more information, see 
Check 
Ethernet Cable Connections on page 139.
•Make sure that your computer’s IP address is on the same subnet as the WiFi DSL 
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 DSL modem router, and 
reboot your computer.
•If your WiFi DSL modem router’s IP address was changed and you do not know the 
current IP address, clear the WiFi DSL modem router’s configuration to factory defaults. 
This procedure sets the WiFi DSL modem router’s IP address to 192.168.0.1. This 
procedure is explained in 
Factory Settings on page 150.
•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 DSL 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 DSL modem router as a replacement 
for an ADSL gateway in your network, the WiFi DSL 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 DSL modem router can obtain an IP address from your Internet service 
provider (ISP). Unless your ISP provides a fixed IP address, your WiFi DSL modem router 
requests an IP address from the ISP. You can determine whether the request was successful 
using the Router Status screen. 
						

							Troubleshooting 
143  D6200 WiFi DSL Modem Router
To check the WAN IP address: 
1. Start your browser and select an external site such as http://www.netgear.com.
2. Access the WiFi DSL modem router interface at http://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 WiFi DSL 
modem router has not obtained an IP address from your ISP.
If your WiFi DSL 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 DSL modem router by restarting 
your network. For more information, see 
Sequence to Restart Your Network on page 139.
If your WiFi DSL 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 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 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 DSL modem router’s MAC address.
-Configure your WiFi DSL modem router to clone your computer’s MAC address.
If your WiFi DSL 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 DSL modem 
router’s configuration, reboot your computer, and verify that 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 DSL modem router configured as its TCP/IP 
gateway.
If your computer obtains its information from the WiFi DSL 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 DSL 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.

Troubleshoot PPPoE
If you are using PPPoE, try troubleshooting your Internet connection.
To troubleshoot a PPPoE connection:
1. Log in to the WiFi DSL modem router.
2. Select Administration > Router Status.
3. Click Connection Status. 
If time remains on Lease Expires, your PPPoE connection is working. Otherwise, there 
might also be a provisioning problem with your ISP.
Note:Unless you connect manually, the WiFi DSL modem router does not 
authenticate using PPPoE until data is transmitted to the network.
Troubleshoot Internet Browsing
If your WiFi DSL modem router can obtain an IP address but your computer is unable to load 
any web pages from the Internet, check the following:
•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 DSL modem 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.
•Your computer might not have the WiFi DSL modem router configured as its default 
gateway.
Reboot the computer, and verify that the WiFi DSL modem 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 WiFi DSL 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.

Changes Not Saved
If the WiFi DSL modem router does not save the changes you make in the WiFi DSL modem 
router interface, check the following:
•When entering configuration settings, always click the Apply button before moving to 
another screen or tab, or your changes are lost. 
•Click the Refresh or Reload button in the web browser. The changes might have 
occurred, but the old settings might be in the web browser’s cache.
Incorrect Date or Time
Select ADVANCED > Security > Schedule to display the current date and time. The WiFi 
DSL modem router uses the Network Time Protocol (NTP) to obtain the current time from 
one of several network time servers on the Internet. Each entry in the log is stamped with the 
date and time of day. Problems with the date and time function can include the following:
•Date shown is January 1, 2000. This value means the WiFi DSL modem router has not 
yet successfully reached a network time server. Check that your Internet access is 
configured correctly. If you have finished setting up the WiFi DSL modem router, wait at 
least 5 minutes, and check the date and time again.
•Time is off by one hour. The WiFi DSL modem router does not automatically sense 
daylight saving time. In the Schedule screen, select the Automatically adjust for daylight 
savings time check box.
Wireless Connectivity
If you are having trouble connecting wirelessly to the WiFi DSL modem router, try to isolate 
the problem. 
•Does the wireless device or computer that you are using find your wireless network?
If not, check the Wireless LED on the front of the WiFi DSL modem router. It should be lit. 
If they are not, you can press the WiFi On/Off button on the side of the WiFi DSL modem 
router to turn the WiFi DSL modem router’s wireless radio back on.
If you disabled the WiFi DSL modem router’s SSID broadcast, then your wireless network 
is hidden and does not show up in your wireless client’s scanning list. By default, SSID 
broadcast is enabled.
•Does your wireless device support the security that you are using for your wireless 
network (WPA or WPA2)?
•If you want to view the wireless settings for the WiFi DSL modem router, use an Ethernet 
cable to connect a computer to a LAN port on the WiFi DSL modem router. Then log in to 
the WiFi DSL modem router and select BASIC > Wireless. FOr more information, see 
Basic Wireless Settings on page 32.

If your wireless device finds your network, but the signal strength is weak, check these 
conditions:
•Is your WiFi DSL modem router too far from your computer, or too close? Place your 
computer near the WiFi DSL modem router, but at least 6 feet away, and see whether the 
signal strength improves.
•Is your wireless signal blocked by objects between the WiFi DSL modem router and your 
computer?
Restore the Factory Settings and Password
This section explains how to restore the factory settings, changing the WiFi DSL modem 
router’s administration password back to password. You can erase the current configuration 
and restore factory defaults in two ways:
•Use the Erase function of the WiFi DSL modem router (see Erase on page 98).
•Use the Reset button on the back of the WiFi DSL modem router. See Factory Settings 
on page 150. If you restore the factory settings and the WiFi DSL modem router fails to 
restart, or the green Power LED continues to blink, the unit might be defective. If the error 
persists, you might have a hardware problem and should contact technical support at 
http://www.netgear.com/support.
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 by using the ping utility in your computer or workstation. 
Test the LAN Path to Your Router
You can ping the WiFi DSL modem router from your computer to verify that the LAN path to 
your WiFi DSL modem router is set up correctly.
To ping the WiFi DSL modem router from a computer running Windows:
1. From the Windows toolbar, click Start and select Run.
2. In the field provided, type ping followed by the IP address of the WiFi DSL modem router, 
as in this example:

3. Click OK. 
						

							Troubleshooting 
147  D6200 WiFi DSL Modem Router
You should see a message like this one:
Pinging  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, you might have one of the following problems:
•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 WiFi DSL 
modem router and computer are connected to a separate Ethernet switch, make sure 
that the Ethernet LEDs are lit for the switch ports that are connected to your computer 
and WiFi DSL modem 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 WiFi DSL modem 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
After verifying that the LAN path works correctly, test the path from your computer to a 
remote device.
1. From the Windows toolbar, click Start and select Run.
2. In the Windows Run window, type:
ping -n 10 
where  is the IP address of a remote device such as your ISP DNS server.
If the path is functioning correctly, replies like the examples shown in the previous section are 
displayed.
If you do not receive replies:
•Check that your computer has the IP address of your WiFi DSL modem router listed as 
the default gateway. If the IP configuration of your computer is assigned by DHCP, this 
information is not visible in your computer’s Network Control Panel. Verify that the IP 
address of the WiFi DSL modem router is listed as the default gateway.
•Check to see that the network address of your computer (the portion of the IP address 
specified by the subnet mask) is different from the network address of the remote device.
•Check that your cable or DSL modem is connected and functioning. 
						

							Troubleshooting 
148 D6200 WiFi DSL Modem Router 
•If your ISP assigned a host name to your computer, enter that host name as the account 
name in the Internet Setup screen.
•Your ISP could be rejecting the Ethernet MAC addresses of all but one of your 
computers.
Many broadband ISPs restrict access by allowing traffic only from the MAC address of your 
broadband modem, but some ISPs additionally restrict access to the MAC address of a 
single computer connected to that modem. If so, configure your WiFi DSL modem router to 
“clone” or “spoof” the MAC address from the authorized computer.
