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 Universal Plug and Play:
1.  Select  Advanced >  UPnP to display the following screen:
Figure 59.  Universal Plug and Play
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 wirele\
ss modem 
router does not allow any device to automatically control the resources,\
 such as port 
forwarding (mapping), of the wireless modem router. 
•     Advertisement Period. The advertisement period is how often the wireless modem  router advertises (broadcasts) its UPnP information. This value can ra\
nge from 1 to 
1440 minutes. The default period is 30 minutes. Shorter durations ensure\
 that control 
points have current device status at the expense of additional network t\
raffic. Longer 
durations might compromise the freshness of the device status but can si\
gnificantly 
reduce network traffic.
•     Advertisement Time To Live . This is measured in hops (steps) for each UPnP 
packet sent. Hops are the steps allowed to propagate for each UPnP adver\
tisement 
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 d\
evices are 
not being updated or reached correctly, you might need to increase this \
value a little.
•     UPnP Portmap Table . The UPnP Portmap Table displays the IP address of each 
UPnP device that is currently accessing the wireless modem router and wh\
ich ports  
						

							Advanced Settings142
N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700 
(internal and external) that device has opened. The UPnP Portmap Table\
 also 
displays what type of port is opened and if that port is still active fo\
r each IP address.

If the error persists, you could have a hardware problem and should cont\
act NETGEAR 
technical support.
Power LED Is Red
When the router is turned on, it performs a power-on self-test. If the P\
ower LED turns red 
after a few seconds or at any other time during normal operation, there \
is a fault within the 
router. 
If the Power LED turns red to indicate a router fault, turn the power of\
f and on to see if the 
wireless modem router recovers. If the power LED is still red 1 minute a\
fter power-up:
•     Turn the power off and on one more time to see if the wireless modem rou\
ter recovers.
•     Clear the router’s configuration to factory defaults as explained in \
Factory Settings on 
page   156. This sets the router’s IP address to 192.168.0.1. 
If the error persists, you could have a hardware problem and should cont\
act NETGEAR 
technical support.
LAN LED Is Off
If the LAN LED does not light when the Ethernet connection is made, chec\
k the following:
•      The Ethernet cable connections are secure at the wireless modem router a\
nd at the hub 
or workstation.
•     The power is turned on to the connected hub or workstation.
Wireless LEDs Are Off
If the 2.4 GHz and 5 GHz Wireless LEDs do not light, the radios might be\
 turned off. Press 
the Wireless On/Off button on the front panel
 to turn the radios back on.
DSL or Internet LED Is Off
If the DSL or Internet LED does not light, check to make sure that you a\
re using the correct 
cable. When connecting the ADSL or Ethernet WAN port, use the cables tha\
t were supplied 
with the wireless modem router. If the DSL or Internet LED is still off,\
 this could mean that 
there is no ADSL or fiber/cable modem service or the cable connected to \
the ADSL or 
Ethernet WAN port is bad.
See also DSL LED Is Off on page  148.

No ISP Connection
If your router cannot access the Internet, first check the ADSL connecti\
on, and then check 
the WAN TCP/IP connections. See 
Figure  60, Front panel LEDs on page  146 for the location 
of the LEDs.
ADSL Link
First determine whether you have an ADSL link with the service provider.\
 The state of this 
connection is indicated by the DSL LED.
DSL LED Is Green or Blinking Green
You have a good ADSL connection. The service provider has connected your\
 line correctly, 
and your wiring is correct.
DSL LED Is Blinking Amber
Your wireless modem router is attempting to make an ADSL connection with\
 the service 
provider. The LED should turn green within 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 and use a microfilter on\
 each telephone as 
described in ADSL Microfilters on page  18. 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 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), you might have poor-quality wiring in your hou\
se.
DSL 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 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 could 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.

Internet LED Is Red
If the Internet LED is red, the device could not connect to the Internet\
. Verify the following:
•     Check that your login credentials are correct. See Log In to the N600 Modem Router on 
page   24 for more information.
•     Check that the information you entered on the Basic Settings screen is c\
orrect. See  Manual Setup (Basic Settings) on page  28.
•     Check with your ISP to verify that the multiplexing method, VPI, and VCI\
 settings on the  ADSL settings screen are correct.
•      Find out if the ISP is having a problem. If it is, wait until that probl\
em is cleared up and try 
again.
Cannot Obtain an Internet IP Address
If your wireless modem router cannot access the Internet, and your Inter\
net LED is green or 
blinking green, check whether the wireless modem router can obtain an In\
ternet IP address 
from the ISP. Unless you have been assigned a static IP address, your wi\
reless modem 
router has to request an IP address from the ISP. 
You can determine whether the request was successful as follows:
1.  Access the router menus at http://192.168.0.1 and log in.
2.  Under Maintenance, select  Router Status and check that an IP address shows for the WAN 
port. If 0.0.0.0 shows, your wireless modem router has not obtained an I\
P address from your 
ISP.
If your router cannot obtain an IP address from the ISP, the problem mig\
ht be one of the 
following:
•      If you have selected a login program, the service name, user name, or pa\
ssword might be 
incorrect. See Debug PPPoE or PPPoA on page  150.
•      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. See 
Setup Wizard on page  27 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 fo\
llowing:
- Inform your ISP that you have bought a new network device and ask them t\
o use the 
router’s MAC address.
- Configure your router to spoof your computer’s MAC address through th\
e Basic 
Settings screen. See Manual Setup (Basic Settings) on page  28.

N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700 
Debug PPPoE or PPPoA
Debug the PPPoE or PPPoA connection as follows:
1. 
Access the router menus at http://192.168.0.1 and log in.
2.  Under Maintenance, select  Router Status.
3.  Click the  Connection Status  button.
4.  If all of the steps indicate OK, your PPPoE or PPPoA connection is worki\
ng.
5.  If any of the steps indicate Failed, you can attempt to reconnect by cli\
cking  Connect. 
The wireless modem router continues to attempt to connect indefinitely. \
If you do not 
connect after several minutes, check that the service name, user name, a\
nd password 
you are using are correct. Also check with your ISP to be sure that ther\
e is no problem 
with their service.
Note:  Unless you connect manually, the wireless modem router does not  authenticate with PPPoE or PPPoA until data is transmitted to the 
network.
Cannot Load an Internet Web Page
If your wireless modem router 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 wi\
reless modem 
router’s configuration, reboot your computer, and verify the DNS addr\
ess. Alternately, you 
can configure your computer manually with DNS addresses, as explained 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.
TCP/IP Network Not Responding
Most TCP/IP terminal devices and routers 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.
