Position Your Modem Router
The modem router lets you access your network from anywhere within the operating range of
your WiFi network. However, the operating distance or range of your WiFi connection can
vary significantly depending on the physical placement of your modem router. For example,
the thickness and number of walls the WiFi signal passes through can limit the range.
For best results, place your modem router according to the following guidelines:
•
Place your modem router on an upper floor of a multifloor home or office.
•
Place your modem router near the center of the area where your computers and other
devices operate, and within line of sight to your WiFi devices.
•
Make sure that the modem router is within reach of an AC power outlet and near Ethernet
cables for wired computers.
•
Place the modem router in an elevated location, minimizing the number walls and ceilings
between the modem router and your other devices.
•
Place the modem router away from electrical devices such as these:
•
-
Ceiling fans
-
Home security systems
-
Microwaves
-
Computers
-
Base of a cordless phone
-
2.4 GHz cordless phone
Place the modem router away from large metal surfaces, large glass surfaces, insulated
walls, and items such as these:
-
Solid metal doors
-
Aluminum studs
-
Fish tanks
-
Mirrors
-
Brick
-
Concrete
When you use multiple access points, it is better if adjacent access points use different radio
frequency channels to reduce interference. The recommended channel spacing between
adjacent access points is five channels (for example, use Channels 1 and 6, or 6 and 11).

Change the MTU Size
The maximum transmission unit (MTU) is the largest data packet a network device transmits.
When one network device communicates across the Internet with another, the data packets
travel through many devices along the way. If a device in the data path uses a lower MTU
setting than the other devices, the data packets must be split or “fragmented” to
accommodate the device with the smallest MTU.
The best MTU setting for NETGEAR equipment is often the default value. In some situations,
changing the value fixes one problem but causes another. Leave the MTU unchanged unless
one of these situations occurs:
Specify Your Internet Settings
27
AC1900 Cable Modem Voice Router
•
You experience problems connecting to your ISP or other Internet service, and the
technical support of either the ISP or NETGEAR recommends changing the MTU setting.
These web-based applications might require an MTU change:
-
A secure website that does not open, or displays only part of a web page
-
Yahoo email
-
MSN portal
-
America Online’s DSL service
•
You use VPN and experience severe performance problems.
•
You used a program to optimize MTU for performance reasons, and now you are
experiencing connectivity or performance problems.
Note: An incorrect MTU setting can cause Internet communication
problems. For example, you might not be able to access certain
websites, frames within websites, secure login pages, or FTP or POP
servers.

Set Up a Default DMZ Server
The default DMZ server feature is helpful when you are using some online games and
videoconferencing applications that are incompatible with Network Address Translation
(NAT). The modem router is programmed to recognize some of these applications and to
work correctly with them, but other applications might not function well. In some cases, one
local computer can run the application correctly if the IP address for that computer is entered
as the default DMZ server.
WARNING:
DMZ servers pose a security risk. A computer designated as the
default DMZ server loses much of the protection of the firewall and
is exposed to exploits from the Internet. If compromised, the DMZ
server computer can be used to attack other computers on your
network.
The modem router usually detects and discards incoming traffic from the Internet that is not a
response to one of your local computers or a service that you configured in the Port
Forwarding/Port Triggering page. Instead of discarding this traffic, you can direct the modem
router to forward the traffic to one computer on your network. This computer is called the
default DMZ server.

Dynamic DNS
Internet service providers (ISPs) assign numbers called IP addresses to identify each
Internet account. Most ISPs use dynamically assigned IP addresses. This means that the IP
address can change at any time. You can use the IP address to access your network
remotely, but most people don’t know what their IP addresses are or when this number
changes.
To make it easier to connect, you can get a free account with a Dynamic DNS service that
lets you use a domain name to access your home network. To use this account, you must set
up the modem router to use Dynamic DNS. Then the modem router notifies the Dynamic
DNS service provider whenever its IP address changes. When you access your Dynamic
DNS account, the service finds the current IP address of your home network and
automatically connects you.
If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic
DNS service does not work because private addresses are not routed on the Internet.

Application Example: Make a Local Web Server Public
If you host a web server on your local network, you can use port forwarding to allow web
requests from anyone on the Internet to reach your web server.

To make a local web server public:
1. Assign your web server either a fixed IP address or a dynamic IP address using DHCP
address reservation.
In this example, your modem router always gives your web server an IP address of
192.168.0.33.
2. On the Port Forwarding/Port Triggering page, configure the modem router to forward the
HTTP service to the local address of your web server at 192.168.0.33.
HTTP (port 80) is the standard protocol for web servers.
Specify Internet Port Settings
111
AC1900 Cable Modem Voice Router
3. (Optional) Register a host name with a Dynamic DNS service, and specify that name in the
Dynamic DNS page.
Dynamic DNS makes it much easier to access a server from the Internet because you
can type the name in the Internet browser. Otherwise, you must know the IP address that
the ISP assigned, which typically changes.
How the Modem Router Implements the Port Forwarding Rule
The following sequence shows the effects of a port forwarding rule:
1. When you type the URL www.example.com in your browser, the browser sends a web
page request message with the following destination information:
• Destination address. The IP address of www.example.com, which is the address of
your modem router.
•
Destination port number. 80, which is the standard port number for a web server
process.
2. Your modem router receives the message and finds your port forwarding rule for incoming
port 80 traffic.
3. The modem router changes the destination in the message to IP address 192.168.0.123
and sends the message to that computer.
4. Your web server at IP address 192.168.0.123 receives the request and sends a reply
message to your modem router.
5. Your modem router performs Network Address Translation (NAT) on the source IP address,
and sends the reply through the Internet to the computer or mobile device that sent the web
page request.
Set Up Port Triggering
Port triggering is a dynamic extension of port forwarding that is useful in these cases:
•
An application must use port forwarding to more than one local computer (but not
simultaneously).
•
An application must open incoming ports that are different from the outgoing port.
With port triggering, the modem router monitors traffic to the Internet from an outbound
“trigger” port that you specify. For outbound traffic from that port, the modem router saves the
IP address of the computer that sent the traffic. The modem router temporarily opens the
incoming port or ports that you specify in your rule, and forwards that incoming traffic to that
destination.
Port forwarding creates a static mapping of a port number or range of ports to a single local
computer. Port triggering can dynamically open ports to any computer when needed and
close the ports when they are no longer needed.
Specify Internet Port Settings
112

Note: If you use applications such as multiplayer gaming, peer-to-peer
connections, real-time communications such as instant messaging, or
remote assistance (a feature in Windows XP), enable Universal
Plug-N-Play (UPnP).
Add a Port Triggering Service

To add a port triggering service:
1. Launch an Internet browser from a computer or mobile device that is connected to the
network.
2. Type http://www.routerlogin.net or http://www.routerlogin.com.
A login window opens.
3. Enter the user name and password.
The user name is admin. The default password is password. The user name and
password are case-sensitive.
The BASIC Home page displays.
4. Select ADVANCED > Advanced Setup > Port Forwarding/Port Triggering.
The Port Forwarding/Port Triggering page displays.
5. Select the Port Triggering radio button.
6. Click the Add Service button.
7. In the Service Name field, type a descriptive service name.
8. In the Service User menu, select Any, or select Single address and enter the IP address
of one computer:
• Any (the default) allows any computer on the Internet to use this service.
•
Single address restricts the service to a particular computer.
9. Select the service type, either TCP or UDP or TCP/UDP (both).
If you are not sure, select TCP/UDP.
Specify Internet Port Settings
113

10. In the Service Type fields, enter the starting and ending ports.
11. Enter the inbound connection port information in the Starting Port and Ending Port fields.
12. Click the Apply button.
The service is now in the Portmap table. You must enable port triggering before the
modem router uses port triggering for the service that you added.
Application Example: Port Triggering for Internet Relay Chat
Some application servers, such as FTP and IRC servers, send replies to multiple port
numbers. Using port triggering, you can tell the modem router to open more incoming ports
when a particular outgoing port starts a session.
An example is Internet Relay Chat (IRC). Your computer connects to an IRC server at
destination port 6667. The IRC server not only responds to your originating source port, but
also sends an “identify” message to your computer on port 113. Using port triggering, you can
tell the modem router, “When you initiate a session with destination port 6667, you must also
allow incoming traffic on port 113 to reach the originating computer.” The following sequence
shows the effects of this port triggering rule you defined:
1. You open an IRC client program to start a chat session on your computer.
2. Your IRC client composes a request message to an IRC server using a destination port
number of 6667, the standard port number for an IRC server process. Your computer then
sends this request message to your modem router.
3. Your modem router creates an entry in its internal session table describing this
communication session between your computer and the IRC server. Your modem router
stores the original information, performs Network Address Translation (NAT) on the source
address and port, and sends this request message through the Internet to the IRC server.
4. Noting your port triggering rule and observing the destination port number of 6667, your
modem router creates another session entry to send any incoming port 113 traffic to your
computer.
5. The IRC server sends a return message to your modem router using the NAT-assigned
source port (for example, port 33333) as the destination port. The IRC server also sends an
“identify” message to your modem router with destination port 113.
6. When your modem router receives the incoming message to destination port 33333, it
checks its session table to see if a session is active for port number 33333. Finding an active
session, the modem router restores the original address information replaced by NAT and
sends this reply message to your computer.
7. When your modem router receives the incoming message to destination port 113, it checks
its session table and finds an active session for port 113 associated with your computer. The
modem router replaces the message’s destination IP address with your computer’s IP
address and forwards the message to your computer.
8. When you finish your chat session, your modem router eventually senses a period of
inactivity in the communications. The modem router then removes the session information
from its session table, and incoming traffic is no longer accepted on port numbers 33333 or
113.

Troubleshoot with the LEDs
You can use the LEDs on the front panel of the modem router for troubleshooting.
Power LED Is Off
•
Make sure that the power cord is securely connected to your modem router and securely
connected to a working power outlet.
•
Check that you are using the power cord that NETGEAR supplied for this product.
•
If the problem persists, contact technical support for help at www.netgear.com/support.
LEDs Never Turn Off
When the modem router is turned on, the LEDs light for about 10 seconds and then turn off. If
all the LEDs stay on, this indicates a fault within the modem router.
If all LEDs are still lit one minute after power-up, do the following:
1. Cycle the power to see if the modem router recovers.
2. Press and hold the Reset button to return the modem router to its factory settings. For more
information, see Factory Settings on page 123.
If the error persists, a hardware problem might exist. Contact technical support at
netgear.com/support.
Internet LED Is Off
If the Internet LED is off and the modem router is connected to the cable television cable, try
the following:
•
Make sure that the coaxial cable connections are secure at the modem router and at the
wall jack.
•
Make sure that your cable Internet provider provisioned your cable Internet service. Your
provider can verify that the signal quality is good enough for modem router service.
•
Remove any excessive splitters that on your cable line. Run a “home run” back to the
point where the cable enters your home.
Troubleshoot the Cable Internet Connection
When your modem router cannot access the Internet and your Internet LED is on, register the
cable MAC address or device MAC address of your modem router with your cable Internet
provider.
Additionally, check to make sure that the setting for your computer’s TCP/IP gateway is set to
use the modem router. If your computer obtains its information from the modem router by
DHCP, reboot the computer and verify the gateway address.
Troubleshooting
116
AC1900 Cable Modem Voice Router
Cannot Log In to the Modem Router
If you are unable to log in to the modem router from a computer or mobile device on your
local network, check the following:
1. Make sure that you are connected to the modem router’s wired or WiFi network.
• For a wired Ethernet connection, make sure that the Ethernet connection is secure
and the modem router is powered on (its Power LED is lit).
•
For a WiFi connection, make sure that you selected the correct network.If you cannot
find the WiFi network, make sure that the modem router is powered on (its Power
LED is lit). If the modem router is powered on, it is possible that someone turned off
the SSID broadcast or the turned off the WiFi radios. See WiFi Connectivity on
page 118.
2. If you are connected to the modem router network, but the web browser does not display the
login window, check the following:
• Make sure that Java, JavaScript, or ActiveX is enabled in your browser. If you are
using Internet Explorer, click the Refresh button to be sure that the Java applet is
loaded.
•
Try quitting the browser and launching it again.
3. If the browser displays the login window, but you cannot access the modem router, make
sure that you are using the correct login information.
The user name is admin, and the default password is password. Both are
case-sensitive. Make sure that Caps Lock is off when you enter this information.
4. If you customized advanced home network settings such as the IP address scheme, check
the following:
• Make sure that the IP address of your computer is on the same subnet as the modem
router. If you are using the recommended addressing scheme, your computer’s
address is 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
modem router, and reboot your computer.
•
If your modem router’s IP address was changed and you do not know the current IP
address, clear the modem router’s configuration to factory defaults. This sets the
modem router’s IP address to 192.168.0.1. For more information, see Factory
Settings on page 123.
Troubleshooting
117

Changes Not Saved
If the modem router does not save the changes you make in the modem router interface,
check the following:
•
When entering configuration settings, always click the Apply button before moving to
another page or tab, or your changes are lost.
•
Click the Refresh or Reload button in the web browser. It is possible that the changes
occurred, but the old settings are in the web browser’s cache.
WiFi Connectivity
If you are experiencing trouble connecting to the modem router with WiFi, try to isolate the
problem:
•
The computer or WiFi device that you are using does not find the WiFi network.
This can happen for the following reasons:
-
Someone pressed the WiFi On/Off button on the modem router, which turned off the
WiFi radios.
Check the 2.4 GHz and 5 GHz LEDs on the front of the modem router. If they are off,
press the WiFi On/Off button to turn the WiFi radios back on.
-
Someone logged in to the modem router and disabled its WiFi radios or set up a WiFi
schedule.
In this case, pressing the WiFi On/Off button does not turn the WiFi radios back on.
You must log in to enable the WiFi radios. Use an Ethernet cable for a wired
connection to the modem router. Then log in and change the settings. For more
information, see Control the WiFi Radios on page 83.
-
Someone logged in to the modem router and disabled its SSID broadcast. Your WiFi
network is hidden and does not display in your WiFi client’s scanning list. (By default,
SSID broadcast is enabled.)
To connect with WiFi, you must type the network SSID and password. For information
about how to enable the SSID broadcast, see Specify Basic WiFi Settings on
page 79.
•
You can find the WiFi network, but you can’t connect. Check the following:
-
Make sure that your computer or WiFi device supports the security that you are using
for your WiFI network (WPA or WPA2),
-
Make sure that you are using the correct WiFi password.
The preset WiFi password is on the modem router label. If you changed it and do not
remember the new password, you can use a wired Ethernet connection to log in to the
modem router and view or change the WiFi password. For more information, see
Change the WiFi Security Option on page 81.
Troubleshooting
118
AC1900 Cable Modem Voice Router
-
Check to see if the WiFi signal strength is weak in your location.
Is your modem router too far from your computer, or too close? Place your computer
near the modem router, but at least 6 feet (1.8 meters) away, and see if the signal
strength improves.
Check for sources of WiFi interference that might block the signal. See Position Your
Modem Router on page 13.
Phone Does Not Get a Dial Tone

To troubleshoot a phone without a dial tone:
1. Check the modem router LEDs:
The Power LED is lit, indicating that the modem router is receiving power.
The Internet LED is lit, indicating that the modem router is connected to the Internet.
The Tel (voice) LEDs indicates the status of the phone line. If this LED is off, the phone
service is not set up. If this LED is blinking, a phone is off the hook.
If the Tel (voice) LED for the line that you are using is lit solid, proceed to the following
step.
2. Make sure that the phone cable is securely connected to the telephone and to the phone
port on the modem router.
3. Connect a different phone and see if the other phone gets a dial tone.
4. Connect a different phone cable.
5. Plug the modem router in to a different electrical outlet.
6. Contact your service provider.
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 using the ping utility in your computer or workstation.
Test the LAN Path to Your Modem Router
You can ping the modem router from your computer to verify that the LAN path to your
modem router is set up correctly.

To ping the modem router from a Windows computer:
1. From the Windows toolbar, click Start and select Run.
2. In the field provided, type ping followed by the IP address of the modem router, as in this
example:
Troubleshooting
119
AC1900 Cable Modem Voice Router
ping www.routerlogin.net
3. Click the OK button.
You should see a message like this one:
Pinging <IP address > 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 be experiencing 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 on for your network devices. If your modem router
and computer are connected to a separate Ethernet switch, make sure that the link LEDs
are lit for the switch ports that are connected to your computer and 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 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 the Start button and select Run.
2. In the Windows Run window, type
ping -n 10 <IP address>
where <IP address> is the IP address of a remote device such as your ISP DNS server.
If the path is functioning correctly, messages like those shown in the previous section display.
If you do not receive replies, check the following:
•
Check to see that the IP address of your modem router listed as the default gateway on
your computer. If DHCP assigns the IP configuration of your computers, this information
is not visible in your computer Network Control Panel. Verify that the IP address of the
modem router is listed as the default gateway.
Troubleshooting
120
AC1900 Cable Modem Voice Router
•
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 to see 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 on the Internet Setup page.
•
Your ISP might 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. If your ISP restricts access to the MAC address of a single
computer connected to that modem, configure your modem router to “clone” or “spoof”
the MAC address from the authorized computer.
