The cable modem router lets you access your network 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 cable
modem router. For example, the thickness and number of walls the WiFi signal passes
through can limit the range.
Additionally, other WiFi access points in and around your home might affect your cable
modem router’s signal. WiFi access points are routers, repeaters, WiFi range extenders,
and any other device that emits a WiFi signal for network access.
Position your cable modem router according to the following guidelines:
•Place your cable 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 cable modem router is within reach of an AC power outlet and
near Ethernet cables for wired computers.

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 cable 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 cable 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, the cable
modem router can forward the traffic to one computer on your network. This computer
is called the default DMZ server.
To set up a default DMZ server:
1. Launch a web browser from a computer or mobile device that is connected to the
cable modem router network.
2. Enter http://routerlogin.net or http://192.168.0.1.

Set Up and Manage 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 cable modem router to use Dynamic DNS. Then the cable 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 cable 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 cable 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.
3. (Optional) Register a host name with a Dynamic DNS service, and specify that name
on the Dynamic DNS page of the cable modem router.
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 Cable 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 cable modem router.
•Destination port number. 80, which is the standard port number for a web server
process.
2. Your cable modem router receives the message and finds your port forwarding rule
for incoming port 80 traffic.
3. The cable 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 cable modem router.
5. Your cable 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 cable modem router monitors traffic to the Internet from an
outbound “trigger” port that you specify. For outbound traffic from that port, the cable
modem router saves the IP address of the computer that sent the traffic. The cable
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.

The service is now in the Portmap table. You must enable port triggering before the
cable modem router used port triggering for the service that you added. See the
following section.
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 cable 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 cable 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:
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 cable modem router.
3. Your cable modem router creates an entry in its internal session table describing
this communication session between your computer and the IRC server. Your cable
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. Based on your port triggering rule and the destination port number of 6667, your
cable 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 cable 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 cable modem router with
destination port 113.
6. When your cable 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 cable modem router restores the original address
information replaced by NAT and sends this reply message to your computer.
7. When your cable 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 cable modem router replaces the message’s destination
User Manual95Specify Internet Port Settings
C6230 WiFi Cable Modem Router
IP address with your computer’s IP address and forwards the message to your
computer.
8. When you finish your chat session, your cable modem router eventually senses a
period of inactivity in the communications. The cable modem router then removes
the session information from its session table, and incoming traffic is no longer
accepted on port numbers 33333 or 113.

User Manual98Troubleshooting
C6230 WiFi Cable Modem Router
Troubleshoot the Cable Internet Connection
When your cable modem router cannot access the Internet and your Internet LED is on,
register the cable MAC address or device MAC address of your cable modem router
with your cable Internet provider.
Additionally, make sure that the cable modem router is specified as the TCP/IP gateway
for your computer. If your computer obtains its information from the cable modem
router by DHCP, reboot the computer and verify the gateway address.
Cannot Log In to the Cable Modem Router
If you are unable to log in to the cable modem router from a computer or mobile device
on your local network, check the following:
1. Make sure that you are connected to the cable modem router’s wired or WiFi network.
•For a wired Ethernet connection, make sure that the Ethernet connection is secure
and the cable 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 cable modem router is powered
on (its Power LED is lit). If the cable modem router is powered on, it is possible
that someone turned off the SSID broadcast or turned off the WiFi radios. See
WiFi Connectivity on page 100.
2. If you are connected to the cable 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 cable modem
router, make sure that you are using the correct login information.

case-sensitive. Make sure that Caps Lock is off when you enter this information.
User Manual99Troubleshooting
C6230 WiFi Cable Modem Router
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
cable 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
cable modem router, and reboot your computer.
•If your cable modem router’s IP address was changed and you do not know the
current IP address, clear the cable modem router’s configuration to factory
defaults. This sets the cable modem router’s IP address to 192.168.0.1.
Changes Not Saved
If the cable modem router does not save the changes you that make in the cable modem
router interface, check the following:
•When entering configuration settings, always click the >Apply button before moving
to another page or tab, or your settings are lost.
•Click the Refresh or Reload button in the web browser. The changes might be saved,
but the old settings might be in the web browser’s cache.
WiFi Connectivity
If you are having trouble connecting to the cable 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 cable modem router, which
turned off the Wradios.
Check the 2.4 GHz and 5 GHz LEDs on the front of the cable modem router. If
they are off, press the WiFi On/Off button to turn the WiFi radios back on.
- Someone logged in to the cable modem router and disabled its WiFi radios or
set up a WiFi schedule.
User Manual100Troubleshooting
C6230 WiFi Cable Modem Router
In this case, pressing the WiFi 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 cable modem router. Then log in and change the settings.
- Someone logged in to the cable 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.
•You can find the WiFi network, but you can’t connect. Check the following:
- Make sure that your computer or device supports the security that you are using
for your WiFi network (WPA or WPA2).
- You are not sure what the WiFi password is.
The preset WiFi password is on the cable 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 cable modem router and view or change the WiFi password.
- The WiFi signal strength is weak in your location.
Is your cable modem router too far from your computer, or too close? Place your
computer near the cable 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.
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 Cable Modem Router
You can ping the cable modem router from your computer to verify that the LAN path
to your cable modem router is set up correctly.
To ping the cable modem router from a Windows-based 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 cable modem
router, as in this example:
ping www.routerlogin.net
User Manual101Troubleshooting
C6230 WiFi Cable Modem Router
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 cable
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 cable 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 cable 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 Test the LAN Path
to Your Cable Modem Router on page 101 display.
If you do not receive replies, check the following:
•Check to see that the IP address of your cable modem router is 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.
User Manual102Troubleshooting
C6230 WiFi Cable Modem Router
Verify that the IP address of the cable modem router is listed as the default
gateway.
•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 additionally restricts access to the MAC
address of a single computer connected to that modem, configure your cable modem
router to “clone” or “spoof” the MAC address from the authorized computer.
