D6200 WiFi DSL Modem Router
•
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 143.
•
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 153.
•
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.
To check the WAN IP address:
1.
Start your browser and select an external site such as
.
2.
Access the WiFi DSL 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 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 143.
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.

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.
