2.  After approximately 10 seconds, verify the following:
•     The LAN Ports LEDs are lit for any local ports that are connected.
•     The DSL LED is lit.
If the DSL link LED is lit, a link has been established to the connected\
 device. If a LAN 
port is connected to a 100 Mbps device, verify that the port’s LED is\
 green. If the port is 
10 Mbps, the LED is amber.
If any of these conditions does not occur, see the appropriate following\
 section.
Welcome Screen Displays instead of Router Main Menu
This situation can occur if the CD Setup Wizard does not finish successf\
ully; the unit stays in 
Wizard Mode. If the Welcome screen displays instead of the main menu whe\

technical support at http://support.netgear.com .
Power LED is red.
The Power LED turns red when 
you press the Restore Factory 
Settings button and blinks red 
three times when that button is 
released. This is normal and does 
not indicate a problem. If the Power LED remains red, there is a fault within the router. 
• Cycle the power to see if the router recovers.
• Clear the router’s configuration to factory defaults. This sets \
the router’s 
IP address to 192.168.0.1. This procedure is explained in  Restore the 
Default Configuration and Password  on page  108.
If the error persists, you might have a hardware problem and should cont\
act 
technical support at http://support.netgear.com .
LEDs never turn off. When the router is turned on, the LEDs turn on for about 10 seconds and \
then turn off. If all the LEDs stay on, there is a fault within the rout\
er.
If all LEDs are still on 1 minute after power-up:
• Cycle the power to see if the router recovers.
• Clear the router’s configuration to factory defaults as explaine\
d in  Restore 
the Default Configuration and Password  on page  108.
If the error persists, you might have a hardware problem and should cont\

DSL LED is off. • Disconnect all telephones on the line. If this solves the problem, \
reconnect the telephones one at a time, being careful to use a microfilt\
er 
on each telephone. If the microfilters are connected correctly, you shou\
ld 
be able to connect all your telephones.
• Check that the telephone company has made the connection to your li\
ne  and tested it.
• Verify that you are connected to the correct telephone line. If you\
 have  more than one phone line, be sure that you are connected to the line wit\
h 
the ADSL service. It might be necessary to use a swapper if your ADSL 
signal is on pins 1 and 4 of the RJ-11 jack. The N300 Wireless ADSL2+

Cannot Log In to the Wireless-N Modem Router
If you are unable to log in to the wireless modem router from a computer\
 on your local 
network, check the following:
•     If you are using an Ethernet-connected computer, check the Ethernet conn\
ection 
between the computer and the router as described in the previous section\
.
•      Make sure that your computer’s IP address is on the same subnet as th\
e router. If you are 
using the recommended addressing scheme, your computer’s address shou\
ld 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 version\
s of Windows and  MacOS will generate and assign an IP address if the computer cannot reac\
h a DHCP 
server. These autogenerated addresses are in the range of 169.254.x.x. I\
f 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 curre\
nt IP address,  clear the router’s configuration to factory defaults. This sets the r\
outer’s IP address to 
192.168.0.1. This procedure is explained in Use the Restore Factory Settings Button to 
Reset the Router on page  108.
•     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 you are using the correct login information. The factory defau\
lt login name is  admin, and the password is password. Make sure that Caps Lock is off when you enter 
this information.
If the router does not save changes you have made while logged in, check\
 the following:
•      When entering configuration settings, be sure to 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 web browser might be caching the old configuration.
The LAN Ports LEDs are off. If the LAN Ports LEDs do not light when the Ethernet connection is made,\
 
check the following:
• Make sure that the Ethernet cable connections are secure at the wir\
eless 
modem router and computer.
• Make sure that power is turned on to the connected modem or compute\
r.
WiFi LED is off. If the WiFi LED does not come on, verify that the  Enable Wireless Router 
Radio  check box is selected on the Wireless Settings screen. See  View or 
Change Wireless Settings on page  34.

Troubleshoot the Internet Connection
If your router is unable to access the Internet, you should check the AD\
SL or mobile 
broadband connection, then the WAN TCP/IP connection. 
DSL Link
If your router is unable to access the Internet, you should first determ\
ine whether you have an 
ADSL link with the service provider. The state of this connection is ind\
icated with the Internet  LED.
DSL LED Is Green or Blinking Green
If your DSL LED is green or blinking green, then you have a good ADSL co\
nnection. You can 
be confident that the service provider has connected your line correctly\
 and that your wiring is 
correct.
DSL LED Is Blinking Amber
If your DSL LED is blinking amber, then your wireless modem router is at\
tempting to make an 
DSL connection with the service provider. The LED should turn green with\
in several minutes. 
If the DSL LED does not turn green, disconnect all telephones on the lin\
e. If this solves the 
problem, reconnect the telephones one at a time, being sure to use a mic\
rofilter on each 
telephone. If the microfilters are connected correctly, you should be ab\
le to connect all your 
telephones.
If disconnecting telephones does not result in a green DSL LED, there mi\
ght be a problem 
with your wiring. If the telephone company has tested the ADSL signal at\
 your network 
interface device (NID), then you might have poor-quality wiring in you\
r house.
DSL LED Is Off
If the DSL LED is off, disconnect all telephones on the line. If this so\
lves the problem, 
reconnect the telephones one at a time, being sure to use a microfilter \
on each telephone. If 
the microfilters are connected correctly, you should be able to connect \
all your telephones.
If disconnecting telephones does not result in a green DSL LED, check fo\
r the following:
•     Check that the telephone company has made the connection to your line an\
d tested it.
•     Verify that you are connected to the correct telephone line. If you have\
 more than one  phone line, be sure that you are connected to the line with the ADSL ser\
vice. It might be 
necessary to use a swapper if your ADSL signal is on pins 1 and 4 or the\
 RJ-11 jack. The 
wireless modem router uses pins 2 and 3. 
						

							Troubleshooting105
 N300 Wireless ADSL2+ Modem Router DGN2200M Mobile Edition
Internet Port LED Is Red
If the Internet Port LED is red, the device was unable to connect to the\
 Internet. Verify the 
following:
•     Check that your login credentials are correct, or that the information y\
ou entered on the 
Basic Settings screen is correct.
•     Check with your ISP to verify that the multiplexing method, VPI, and VCI\
 settings on the  ADSL settings screen are correct.
•     Check if your ISP has a problem—it might not be that the router canno\
t connect to the  Internet but that your ISP cannot provide an Internet connection.
Connecting to Mobile Broadband
If you are unable to connect to mobile broadband, check the following:
•     The Internet account is active.
•     Wireless broadband coverage is available where the unit is located. Test\
 this availability by connecting the USB modem to the laptop directly.
•      Access the router main menu to verify that the configurations of the bro\
adband settings 
are correct. Check with your ISP if unsure.
•     Check the SIM PIN code (if used).
Obtain an Internet IP Address
If your wireless modem router is unable to access the Internet, and your\
 Internet Port LED is 
green or blinking green, you should determine whether the wireless modem\
 router is able to 
obtain an Internet IP address from the ISP. Unless you have been assigne\
d a static IP 
address, your wireless modem router needs to request an IP address from \
the ISP. You can 
determine whether the request was successful using the browser interface\
.
To check the Internet IP address from the browser interface: 
1.  Launch your browser, and select an external site such as www.netgear.com .
2.  Access the main menu of the wireless modem router’s configuration at \
http://192.168.0.1.
3.  In the main menu, under Maintenance, select  Router Status, and check that an IP address 
is shown for the WAN port. If 0.0.0.0 is shown, your wireless modem rout\
er has not obtained 
an IP address from your ISP.
If your router is unable to obtain an IP address from the ISP, the probl\
em might be one of the 
following:
•      If you have selected a login program, the service name, user name, or pa\
ssword might be 
incorrectly set. See the following section,  Troubleshoot PPPoE or PPPoA .
•      Your ISP might check for your computer’s host name. Assign the comput\
er host name of 
your ISP account to the wireless modem router in the browser-based Setup\
 Wizard. 
						

							Troubleshooting106
N300 Wireless ADSL2+ Modem Router DGN2200M Mobile Edition 
•     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 followin\
g:
- 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 spoof your computer’s MAC address. This can \
be done in the 
Basic Settings screen. 
Troubleshoot PPPoE or PPPoA
The PPPoE or PPPoA connection can be debugged as follows:
1. Access the main menu of the router at http://192.168.0.1.
2.  Under Maintenance, select  Router Status.
3.  Click the  Connection Status  button.
4.  If all of the steps indicate OK, then your PPPoE or PPPoA connection is \
up and working.
5.  If any of the steps indicates Failed, you can attempt to reconnect by cl\
icking  Connect. The 
wireless modem router will continue to attempt to connect indefinitely.
If you cannot connect after several minutes, you might be using an incor\
rect service name, 
user name, or password. There also might be a provisioning problem with \
your ISP.
Note:  Unless you connect manually, the wireless modem router will not  authenticate using PPPoE or PPPoA until data is transmitted to the 
network.
Troubleshoot Internet Browsing
If your wireless modem router can obtain an IP address, but your compute\
r 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 wi\
reless modem 
router’s configuration, reboot your computer, and verify the DNS addr\
ess. Alternatively, 
you can configure your computer manually with DNS addresses, as explaine\
d in your 
operating system documentation.
•     Your computer might not have the wireless modem router configured as its\
 TCP/IP  wireless modem router.
If your computer obtains its information from the wireless modem router \
by DHCP, reboot 
the computer, and verify the wireless modem router address.

 N300 Wireless ADSL2+ Modem Router DGN2200M Mobile Edition
Troubleshoot a TCP/IP Network Using the Ping Utility
Most TCP/IP terminal devices and routers contain a ping utility that sen\
ds an echo request 
packet to the designated device. The device then responds with an echo r\
eply. You can 
easily troubleshoot a TCP/IP network by using the ping utility in your c\
omputer.
Test the LAN Path to Your Wireless-N Modem Router
You can ping the router from your computer to verify that the LAN path t\
o your router is set up 
correctly.
To ping the router from a PC running Windows 95 or later:
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:
ping 192.168.0.1
3.  Click  OK.
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 could have one of the foll\
owing problems:
•     Wrong physical connections -      Make sure that the LAN Port LED is on. If the LED is off, follow the ins\
tructions in 
Troubleshoot with the LEDs  on page  101.
-     Check that the corresponding Link LEDs are on for your network interface\
 card  and for the hub ports (if any) that are connected to your workstation \
and router.
•     Wrong network configuration -     Verify that the Ethernet card driver software and TCP/IP software are bo\
th installed and configured on your computer or workstation.
-      Verify that the IP address for your router and your workstation are corr\
ect 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 yo\
ur computer to a remote 
device. In the Windows Run screen, type:
ping -n 10 IP address 
						

							Troubleshooting108
N300 Wireless ADSL2+ Modem Router DGN2200M Mobile Edition 
where IP address is the IP address of a remote device such as your ISP’s DNS server.
If the path is functioning correctly, replies as in the previous section\
 are displayed. If you do 
not receive replies:
•     
Check that your computer has the IP address of your router listed as the\
 default wireless 
modem router. If the IP configuration of your computer is assigned by DH\
CP, this 
information will not be visible in your computer’s Network Control Pa\
nel. Verify that the IP 
address of the router is listed as the default wireless modem router.
•     Check to see that the network address of your computer (the portion of \
the IP address  specified by the netmask) is different from the network address of the \
remote device.
•     Check that your cable or DSL modem is connected and functioning.
•      If your ISP assigned a host name to your computer, enter that host name \
as the account 
name in the Basic Settings 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 MA\
C address of 
your broadband modem, but some ISPs additionally restrict access to the \
MAC address 
of a single computer connected to that modem. If this is the case, you n\
eed to configure 
your router to “clone” or “spoof” the MAC address from the a\
uthorized computer.
Restore the Default Configuration and Password
This section explains how to restore the factory default configuration s\
ettings, changing the 
router’s administration password to  password and the IP address to 192.168.0.1. You can 
erase the current configuration and restore factory defaults in two ways\
:
•     Use the Erase function (see Back Up, Restore, and Erase Your Settings on page  54).
•     Press the Restore Factory Settings button on the bottom of the router.
Use the Restore Factory Settings Button to Reset the Router
To restore the factory default configuration settings when you do not kn\
ow the administration 
password or IP address, use the Restore Factory Settings button on the b\
ottom of the router.
To reset the router:
1.  Press and hold the  Restore Factory Settings button until the Power LED turns red 
(about 6 seconds).
2.  Release the Restore Factory Settings  button. The LED blinks red three times and then 
turns green when the router has reset to the factory default state. Wait\
 for the router to 
reboot.
Problems with Date and Time
In the main menu, under Security, select  Schedule to display the current date and time of 
day. The wireless modem router uses the Network Time Protocol (NTP) to\
 obtain the current
