For example, if your external address is 134.177.0.123 at port number 8080, enter the 
following in your browser:
http://134.177.0.123:8080
Note: The http:// is required in the address.
Static Routes
Static routes provide additional routing information to your modem. Under normal 
circumstances, the modem has adequate routing information after it has been configured for 
Internet access, and you do not need to configure additional static routes.Configure static 
routes only for unusual cases, such when you have multiple routers or multiple IP subnets on 
your network.
Static Route Example
As an example of when a static route is needed, consider the following case:
•     Your primary Internet access is through a cable modem to an ISP.
•     You have an ISDN modem on your home network for connecting to the company where 
you are employed. This modem’s address on your LAN is 192.168.0.100.
•     Your company’s network address is 134.177.0.0.
When you first configured your modem, two implicit static routes were created. A default route 
was created with your ISP as the broadband ADSL2+ modem, and a second static route was 
created to your local network for all 192.168.0.x addresses. With this configuration, if you 
attempt to access a device on the 134.177.0.0 network, your modem forwards your request 
to the ISP. The ISP forwards your request to the company where you are employed, and the 
request is likely to be denied by the company’s firewall.
In this case you have to define a static route, telling your modem that 134.177.0.0 should be 
accessed through the ISDN modem at 192.168.0.100. 
In this example:
•     The Destination IP Address and IP Subnet Mask fields specify that this static route 
applies to all 134.177.x.x addresses. 
•     The Gateway IP Address field specifies that all traffic for these addresses are to be 
forwarded to the ISDN modem at 192.168.0.100. 
•     The value in the Metric field represents the number of modems between your network 
and the destination. This is a direct connection, so it can be set to the minimum value 
of
 2.
•     The Private check box is selected only as a precautionary security measure in case RIP 
is activated.

Universal Plug and Play
Universal Plug and Play (UPnP) helps devices, such as Internet applian\
ces and computers, 
access the network and connect to other devices as needed. UPnP devices \
can 
automatically discover the services from other registered UPnP devices o\
n the network.
To configure UPnP:
1. Select  Advanced >  UPnP to display the following screen:
2. Fill in the settings as follows:
Turn UPnP On . UPnP can be enabled or disabled for automatic device configuration. 
The default setting for UPnP is enabled. If UPnP is disabled, the modem \
does not allow 
any device to automatically control the resources, such as port forwardi\
ng (mapping), of 
the modem. 
Advertisement Period . The advertisement period is how often the modem advertises 
(broadcasts) its UPnP information. This value ranges from 1 to 1440 mi\
nutes. The default 
is 30 minutes. Shorter durations ensure that control points have current\
 device status at 
the expense of additional network traffic. Longer durations might compro\
mise the device 
status freshness but can significantly reduce network traffic.
Advertisement Time To Live . This is measured in hops (steps) for each UPnP packet 
sent. Hops are the number of steps allowed to propagate for each UPnP ad\
vertisement 
before it disappears. The number of hops can range from 1 to 255. The de\
fault value is 4 
hops, which works for most home networks. If you notice that some device\
s are not being 
updated or reached correctly, you might need to increase this value a li\
ttle. 
						

							Advanced Settings64

							Troubleshooting
67  Broadband ADSL2+ Modem DM111PSPv2
Power LED Is Red
When the modem is turned on, it performs a power-on self-test. If the Power LED turns red 
after a few seconds or at any other time during normal operation, there is a fault within the 
modem. 
If the Power LED turns red to indicate a modem fault, turn the power off and on to see if the 
broadband ADSL2+ modem recovers. If the power LED is still red 1 minute after power-up:
•     Turn the power off and on one more time to see if the broadband ADSL2+ modem 
recovers.
•     Clear the modem’s configuration to factory defaults as explained in Factory Settings on 
page 75. This sets the modem’s IP address to 192.168.0.1. 
If the error persists, you could have a hardware problem and should contact NETGEAR 
technical support.
Ethernet LED Is Off
If the Ethernet LED does not light when the Ethernet connection is made, check the following:
•     The Ethernet cable connections are secure at the modem and at the hub or workstation.
•     The power is turned on to the connected hub or workstation.
•     You are using the correct cable. When connecting the DSL port, use the cable that was 
supplied with the modem. If the DSL link LED is still off, this could mean that there is no 
DSL service or the cable connected to the DSL port is bad.
See also DSL Link LED Is Off on page 68.
No Internet Connection
If your modem cannot access the Internet, first check the DSL connection, and then check 
the WAN TCP/IP connections. See 
Figure 11, Front panel LED icons on page 66 for the 
location of the LEDs.
DSL Link
First determine whether you have a DSL link with the service provider. The state of this 
connection is indicated by the DSL LED.
DSL Link LED Is Green or Blinking Green
You have a good DSL connection. The service provider has connected your line correctly, 
and your wiring is correct. 
						

							Troubleshooting
68 Broadband ADSL2+ Modem DM111PSPv2 
DSL Link LED Is Blinking Green
Your broadband ADSL2+ modem is attempting to make a DSL connection with the service 
provider. The LED should turn green within several minutes. 
If the DSL link LED does not turn green, disconnect all telephones on the line. If this solves 
the problem, reconnect the telephones one at a time and use a microfilter on each telephone 
as described in 
ADSL Microfilters on page 10. If you connect the microfilters correctly, you 
should be able to connect all your telephones.
If disconnecting telephones does not result in a green DSL link LED, there might be a 
problem with your wiring. If the telephone company has tested the DSL signal at your network 
interface device (NID), you might have poor-quality wiring in your house.
DSL Link LED Is Off
First disconnect all telephones on the line. If this solves the problem, reconnect the 
telephones one at a time, and 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 link LED, check for the following:
•     Check that the telephone company has made the connection to your line 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 with the DSL service. It could be 
necessary to use a swapper if your DSL signal is on pins 1 and 4 or the RJ-11 jack. The 
modem uses pins 2 and 3.
Internet LED Is Red
If the Internet LED is red, the device could not connect to the Internet. Verify the following:
•     Check that your log-in credentials are correct. See Log In to the Modem on page 17 for 
more information.
•     Check that the information you entered on the Basic Settings screen is correct. See 
Manual Setup (Basic Settings) on page 21.
•     Check with your ISP to verify that the multiplexing method, VPI, and VCI settings on the 
DSL settings screen are correct.
•     Find out if the ISP is having a problem. If it is, wait until that problem is cleared up, and try 
again.
Cannot Obtain an Internet IP Address
If your modem cannot access the Internet, and your Internet LED is green or blinking green, 
check whether the modem can obtain an Internet IP address from the ISP. Unless you have 
been assigned a static IP address, your modem has to request an IP address from the ISP. 
You can determine whether the request was successful as follows:
1. Access the modem menus at http://192.168.0.1 and log in. 
						

							Troubleshooting
69  Broadband ADSL2+ Modem DM111PSPv2
2. Under Maintenance, select Router Status, and check that an IP address shows for the 
WAN port. If 0.0.0.0 shows, your modem has not obtained an IP address from your ISP.
If your modem cannot obtain an IP address from the ISP, the problem might be one of the 
following:
•     If you have selected a login program, the service name, user name, or password might be 
incorrect. See 
Debug PPPoE or PPPoA on page 69.
•     Your ISP might check for your computer’s host name. Assign the computer host name of 
your ISP account to the modem in the browser-based Setup Wizard. See 
Setup Wizard 
on page 20 for more information.
•     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 
modem’s MAC address.
-Configure your modem to spoof your computer’s MAC address through the Basic 
Settings screen. See 
Manual Setup (Basic Settings) on page 21.
Debug PPPoE or PPPoA
To debug the PPPoE or PPPoA connection:
1. Access the modem menus at http://192.168.0.1 and log in.
2. Select Maintenance > Router Status.
3. Click the Connection Status button.
4. If all of the steps indicate OK, your PPPoE or PPPoA connection is working.
5. If any of the steps indicate Failed, you can attempt to reconnect by clicking Connect. 
The modem continues to attempt to connect indefinitely. If you do not connect after 
several minutes, check that the service name, user name, and password you are using 
are correct. Also check with your ISP to be sure that there is no problem with their 
service.
Note:  Unless you connect manually, the modem does not authenticate 
with PPPoE or PPPoA until data is transmitted to the network.

Cannot Load an Internet Web Page
If your modem can obtain an IP address, but your browser cannot load any Internet web 
pages:
•     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 broadband 
ADSL2+ modem’s configuration, reboot your computer, and verify the DNS address. 
Alternately, you can configure your computer manually with DNS addresses, as explained 
in your operating system documentation.
•     Your computer might not have the modem configured as its TCP/IP router.
If your computer obtains its information from the modem by DHCP, reboot the computer, 
and verify the modem address.
TCP/IP Network Not Responding
Most TCP/IP terminal devices and modems have a ping utility for sending an echo request 
packet to the designated device. The device responds with an echo reply to tell whether a 
TCP/IP network is responding to requests.
Test the LAN Path to Your Modem
You can ping the modem from your computer to verify that the LAN path to your modem is set 
up correctly.
To ping the modem from a PC running Windows 95 or later:
1. From the Windows taskbar, click the Start button, and select Run.
2. In the field provided, type ping followed by the IP address of the modem, as in this example:
ping 192.168.0.1
3. Click OK.
a.You should see a message like this one:
“Pinging  with 32 bytes of data”
b. If the path is working, you see this message:
“Reply from < IP address >: bytes=32 time=NN ms TTL=xxx”
c. 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 following problems:
•     Wrong physical connections
