The Status page shows hardware and software information about the DCM-604 that may be useful to your cable service provider.
11
DCM-604 Series EMTA Embedded Multimedia Terminal Adaptor
User’s Manual
5.2.1 Software Status
The Software page shows how long the DCM-604 has operated since last being powered up, and some key information the DCM-604 received during the initialization process with your cable service provider.
If Network Access shows “Allowed,” then your cable service provider has configured the DCM-604 to have Internet connectivity. If Network Access shows otherwise, you may not have Internet access, and please contact your cable service provider for assistance.
5.3 Basic
The Basic page contains the basic features of DCM-604 including Setup, DHCP and
Backup
5.3.1 DHCP
The DHCP page allows you to activate/deactivate the DHCP server function of the DCM-
604, and, if the DHCP server is activated, to see DHCP leases it has provided.
With this function activated, your cable service provider’s DHCP server provides one IP address for the DCM-604, and the DCM-604’s DHCP server provides IP addresses, starting at the address you set in Starting Local Address field, to your PCs. A DHCP server leases an IP address with an expiration time.
To set the maximum number of PCs to which the DCM-604 will issue IP addresses, enter it in the Number of CPEs box and then click Apply. (CPE is another term sometimes used for PC.)
12
DCM-604 Series EMTA Embedded Multimedia Terminal Adaptor
User’s Manual
The table on the bottom of this page shows the information of DHCP clients including the
IP and MAC addresses of each PC. Since MAC addresses are unique and permanently fixed into hardware, you can identify any PC listed by its MAC address. The DCM-604 provides leases for 3600 seconds (default), and has an automatic renewal mechanism that will keep extending a lease as long as the associated PC remains active.
You can cancel an IP address lease by selecting it in the DHCP Client Lease Info list and then clicking the Force Available button. If you do this, you may have to perform a DHCP
Renew on that PC, so it can obtain a new lease.
5.4 Advanced
The Advanced page allows you to enable/disable some advanced features of the DCM-
604.
5.4.1 Options
The Options page allows you to enable/disable some advanced features supported by
DCM-604
.
Check the option you want to use and click Apply button to enable the function(s).
WAN Blocking: To prevent others on the WAN side from being able to ping your
DCM-604. With WAN Blocking on, your DCM-604 will not respond to pings it receives, effectively “hiding” your gateway.
Ipsec PassThrough: To enable IpSec type packets to pass through between WAN
and LAN.
PPTP PassThrough: To enable PPTP type packets to pass through between WAN
and LAN.
Remote Config Management: To make the Web Management pages of your DCM-
604 accessible from the WAN side. Page access is limited to only those who know the
DCM-604 access password you set in the Status--Security page.
When accessing the DCM-604 from a remote location, you must use HTTP port 8080 and your IP address. This is the "WAN IP address" that appears at the Basic--Setup
13
DCM-604 Series EMTA Embedded Multimedia Terminal Adaptor
User’s Manual
page. For example, if this IP address were 211.20.15.28, you would navigate to http://
211.20.15.28:8080 to reach the DCM-604’s Web Management page from a remote location.
Multicast Enable: To enable multicast traffic to pass through between WAN and LAN.
You may need to enable this to see some types of broadcast streaming and content on the Internet, such as webcasting of a popular live event.
UPnP Enable: UPnP (Universal Plug and Play) offers pervasive peer-to-peer network
connectivity of PCs of all form factors, intelligent appliances, and wireless devices.
UPnP architecture leverages TCP/IP and the Web to enable seamless proximity networking in addition to control and data transfer among networked devices in the home, office, and everywhere in between.
5.4.2 IP Filtering
The IP Filtering page enables you to enter the IP address ranges of PCs on your LAN that you don’t permit to have outbound access ability to the WAN. These PCs can still communicate with each other on your LAN, but packets they originate to WAN addresses are blocked by the DCM-604.
To enable IP Filtering feature of DCM-604, check the Enable box and click Apply button.
5.4.3 MAC Filtering
The MAC Filtering page enables you to enter the MAC address of specific PCs on your
LAN that you don’t permit to have outbound access ability to the WAN. These PCs can still communicate with each other through the DCM-604, but packets they send to WAN addresses are blocked.
14
DCM-604 Series EMTA Embedded Multimedia Terminal Adaptor
User’s Manual
To enable MAC filtering feature of DCM-604, enter the MAC address of the LAN device and click Apply button.
5.4.4 Port Filtering
The Port Filtering page allows you to enter ranges of destination ports (applications) that you don’t want your LAN PCs to send packets to. Any packets your LAN PCs send to these destination ports will be blocked. For example, you could block access to worldwide web browsing (HTTP port 80) but still allow email service (SMTP port 25 and POP3 port
110).
To enable port filtering, enter the Start port and End port for each range. Then select its protocol form the drop-down list and check the Enable box, and click Apply button. To block only one port, set both Start and End ports the same.
5.4.5 Forwarding
For communications between LAN and WAN, the DCM-604 normally only allows you to originate an IP connection with a PC on the WAN; it will ignore attempts of the WAN PC to originate a connection onto your PC. This protects you from malicious attacks from outsiders. However, sometimes you may wish for anyone outside to be able to originate a connection to a particular PC on your LAN if the destination port (application) matches one you specify.
The Forwarding page allows you to specify up to 10 rules.
15
DCM-604 Series EMTA Embedded Multimedia Terminal Adaptor
User’s Manual
Using the Port Forwarding page, you can provide local services (web servers, FTP servers, mail servers, etc) for people on the Internet or play Internet games. A table of commonly used port numbers is also provided.
5.4.6 Port Triggers
The Port Triggers page allows you to configure dynamic triggers to specific devices on the
LAN. This allows for special applications that require specific port numbers with bidirectional traffic to function properly. Applications such as video conferencing, voice, gaming, and some messenging program features may require these special settings.
Port Triggering is an elegant mechanism that does the forwarding for you, each time you play the game.
You can specify up to 10 port ranges on which to trigger.
5.4.7 DMZ Host
The DMZ page allows you to configure a specific network device to be exposed or visible directly to the WAN (public Internet). Setting a host on your local network as demilitarized zone (DMZ) forwards any network traffic that is not redirected to another host via the port forwarding feature to the IP address of the host (PC). This designates one PC on your
LAN that should be left accessible to all PCs from the WAN side for all ports. For example,
16
DCM-604 Series EMTA Embedded Multimedia Terminal Adaptor
User’s Manual
if you locate a HTTP server on this machine, anyone will be able to access that HTTP server by using your DCM-604’s IP address as the destination. This may be used when problem applications do not work with port triggers. The setting of “0” indicates NO DMZ
PC.
5.5.1 User Setup
This page allows configuration of users. “White List Only” feature limits the user to visit only the sites, specified in the Allowed Domain List of his/her content rule.
5.5.2 Basic Setup

6. Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the DCM-604. Read the following descriptions if you are having problems.
(The examples below are illustrated in Windows® XP. If you have a different operating system, the screenshots on your computer will look similar to the following examples.)
1. Why can’t I access the web-based configuration utility?
When entering the IP address of the D-Link router (192.168.0.1 for example), you are not connecting to a website on the Internet or have to be connected to the Internet. The device has the utility built-in to a ROM chip in the device itself. Your computer must be on the same IP subnet to connect to the web-based utility.
• Make sure you have an updated Java-enabled web browser. We recommend the following:
• Internet Explorer 6.0 or higher
• Netscape 8 or higher
• Mozilla 1.7.12 (5.0) or higher
• Opera 8.5 or higher
• Safari 1.2 or higher (with Java 1.3.1 or higher)
• Camino 0.8.4 or higher
• Firefox 1.5 or higher
• Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a different cable or connect to a different port on the device if possible. If the computer is turned off, the link light may not be on.
• Disable any internet security software running on the computer. Software firewalls such as Zone Alarm, Black Ice, Sygate, Norton Personal Firewall, and Windows® XP firewall may block access to the configuration pages. Check the help files included with your firewall software for more information on disabling or configuring it.
‧ Configure your Internet settings:
• Go to Start > Settings > Control Panel. Double-click the Internet Options Icon. From the Security tab, click the button to restore the settings to their defaults.
• Click the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings button. Make sure nothing is checked. Click OK.
• Go to the Advanced tab and click the button to restore these settings to their defaults.
Click OK three times.
• Close your web browser (if open) and open it.
• Access the web management. Open your web browser and enter the IP address of your
D-Link router in the address bar. This should open the login page for your the web management.
• If you still cannot access the configuration, unplug the power to the router for 10 seconds and plug back in. Wait about 30 seconds and try accessing the configuration. If you have multiple computers, try connecting using a different computer.
2. What can I do if I forgot my password?
If you forgot your password, you must reset your router. Unfortunately this process will change all your settings back to the factory defaults.
23
DCM-604 Series EMTA Embedded Multimedia Terminal Adaptor
User’s Manual
To reset the router, locate the reset button (hole) on the rear panel of the unit. With the router powered on, use a paperclip to hold the button down for 10 seconds. Release the button and the router will go through its reboot process. Wait about 30 seconds to access the router. The default IP address is 192.168.0.1. When logging in, the username is
“admin” and the password is “password”.
3. Why can’t I connect to certain sites or send and receive emails when connecting
through my router?
If you are having a problem sending or receiving email, or connecting to secure sites such as eBay, banking sites, and Hotmail, we suggest lowering the MTU in increments of ten
(Ex. 1492, 1482, 1472, etc).
Note: AOL DSL+ users must use MTU of 1400.
To find the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination could be another computer, or a URL.
• Click on Start and then click Run.
• Windows® 95, 98, and Me users type in command (Windows® NT, 2000, and XP users type in cmd) and press Enter (or click OK).
• Once the window opens, you’ll need to do a special ping. Use the following syntax: ping
[url] [-f] [-l] [MTU value]
Example: ping yahoo.com -f -l 1472
You should start at 1472 and work your way down by 10 each time. Once you get a reply, go up by 2 until you get a fragmented packet. Take that value and add 28 to the value to account for the various TCP/IP headers. For example, lets say that 1452 was the proper value, the actual MTU size would be 1480, which is the optimum for the network we’re working with (1452+28=1480).
Once you find your MTU, you can now configure your router with the proper MTU size.
24
DCM-604 Series EMTA Embedded Multimedia Terminal Adaptor
User’s Manual
To change the MTU rate on your router follow the steps below:
• Open your browser, enter the IP address of your router (192.168.0.1) and click OK.
• Enter your username (admin) and password (password). Click OK to enter the web configuration page for the device.
• Click on Setup and then click Manual Configure.
• To change the MTU enter the number in the MTU field and click Save Settings to save your settings.
• Test your email. If changing the MTU does not resolve the problem, continue changing the MTU in increments of ten.

Wireless Basics
D-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless connectivity within your home, business or public access wireless networks. Strictly adhering to the IEEE standard, the D-Link wireless family of products will allow you to securely access the data you want, when and where you want it.
You will be able to enjoy the freedom that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals instead of wires. Wireless LANs are used increasingly in both home and office environments, and public areas such as airports, coffee shops and universities. Innovative ways to utilize WLAN technology are helping people to work and communicate more efficiently. Increased mobility and the absence of cabling and other fixed infrastructure have proven to be beneficial for many users.
Wireless users can use the same applications they use on a wired network. Wireless adapter cards used on laptop and desktop systems support the same protocols as
Ethernet adapter cards.

Under many circumstances, it may be desirable for mobile network devices to link to a conventional Ethernet LAN in order to use servers, printers or an Internet connection supplied through the wired LAN. A Wireless Router is a device used to provide this link.
What is Wireless?
Wireless or Wi-Fi technology is another way of connecting your computer to the network without using wires. Wi-Fi uses radio frequency to connect wirelessly, so you have the freedom to connect computers anywhere in your home or office network.
Why D-Link Wireless?
D-Link is the worldwide leader and award winning designer, developer, and manufacturer of networking products. D-Link delivers the performance you need at a price you can afford. D-Link has all the products you need to build your network.
How does wireless work?
Wireless works similar to how cordless phone work, through radio signals to transmit data from one point A to point B. But wireless technology has restrictions as to how you can access the network. You must be within the wireless network range area to be able to connect your computer. There are two different types of wireless networks Wireless Local
Area Network (WLAN), and Wireless Personal Area Network (WPAN).
Wireless Local Area Network (WLAN)
In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The access point has a small antenna attached to it, which allows it to transmit data back and forth over radio signals. With an indoor access point as seen in the picture, the signal can travel up to 300 feet. With an outdoor access point the signal can reach out up to 30 miles to serve places like manufacturing plants, industrial locations, college and high school campuses, airports, golf courses, and many other outdoor venues.
Wireless Personal Area Network (WPAN)
Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices in WPAN operate in a range up to 30 feet away.
Compared to WLAN the speed and wireless operation range are both less than WLAN, but in return it doesn’t use nearly as much power which makes it ideal for personal devices, such as mobile phones, PDAs, headphones, laptops, speakers, and other devices that operate on batteries.
Who uses wireless?
Wireless technology as become so popular in recent years that almost everyone is using it, whether it’s for home, office, business, D-Link has a wireless solution for it.

Where is wireless used?
Wireless technology is expanding everywhere not just at home or office. People like the freedom of mobility and it’s becoming so popular that more and more public facilities now provide wireless access to attract people. The wireless connection in public places is usually called “hotspots”.
Using a D-Link Cardbus Adapter with your laptop, you can access the hotspot to connect to Internet from remote locations like: Airports, Hotels, Coffee Shops, Libraries,
Restaurants, and Convention Centers.
Wireless network is easy to setup, but if you’re installing it for the first time it could be quite a task not knowing where to start. That’s why we’ve put together a few setup steps and tips to help you through the process of setting up a wireless network.
Tips
Here are a few things to keep in mind, when you install a wireless network.
Centralize your router or Access Point
Make sure you place the router/access point in a centralized location within your network for the best performance. Try to place the router/access point as high as possible in the room, so the signal gets dispersed throughout your home. If you have a two-story home, you may need a repeater to boost the signal to extend the range.
Eliminate Interference
Place home appliances such as cordless telephones, microwaves, and televisions as far away as possible from the router/access point. This would significantly reduce any interference that the appliances might cause since they operate on same frequency.
Security
Don’t let your next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning on the WPA or WEP security feature on the router. Refer to product manual for detail information on how to set it up.
Wireless Modes
There are basically two modes of networking:
• Infrastructure – All wireless clients will connect to an access point or wireless router.
• Ad-Hoc – Directly connecting to another computer, for peer-to-peer communication, using wireless network adapters on each computer, such as two or more DCM-604 wireless network Cardbus adapters.
An Infrastructure network contains an Access Point or wireless router. All the wireless devices, or clients, will connect to the wireless router or access point.
An Ad-Hoc network contains only clients, such as laptops with wireless cardbus adapters.
All the adapters must be in Ad-Hoc mode to communicate.

Check your IP address
After you install your new D-Link adapter, by default, the TCP/IP settings should be set to obtain an IP address from a DHCP server (i.e. wireless router) automatically. To verify your IP address, please follow the steps below.
Click on Start > Run. In the run box type cmd and click OK. (Windows® Vista users type cmd in the Start Seach box.)
At the prompt, type ipconfig and press Enter.
This will display the IP address, subnet mask, and the default gateway of your adapter.
If the address is 0.0.0.0, check your adapter installation, security settings, and the settings on your router. Some firewall software programs may block a DHCP request on newly installed
Statically Assign an IP address
If you are not using a DHCP capable gateway/router, or you need to assign a static IP address, please follow the steps below:
Step 1
Windows® Vista - Click on Start > Control Panel > Network and Internet > Network and
Sharing Center > Manage Network Connections.
Windows® XP - Click on Start > Control Panel > Network Connections.
Windows® 2000 - From the desktop, right-click My Network Places > Properties.
Step 2
Right-click on the Local Area Connection which represents your network adapter and select Properties.
Step 3
Highlight Internet Protocol (TCP/IP) and click Properties.
Step 4
Click Use the following IP address and enter an IP address that is on the same subnet as your network or the LAN IP address on your router.

Example: If the router´s LAN IP address is 192.168.0.1, make your IP address
192.168.0.X where X is a number between 2 and 99. Make sure that the number you choose is not in use on the network. Set Default Gateway the same as the LAN IP address of your router (192.168.0.1).
Set Primary DNS the same as the LAN IP address of your router (192.168.0.1). The
Secondary DNS is not needed or you may enter a DNS server from your ISP.
Step 5
Click OK twice to save your settings.
