Section 2 - Installation

L7-N-R2000 User Manual

Installation

This section will walk you through the installation process. Placement of the router is very important. Do not place the router in an enclosed area such as a closet, cabinet, or in the attic or garage.

Before you Begin

Please congure the router with the computer that was last connected directly to your modem. Also, you can only use the Ethernet port on your modem. If you were using the USB connection before using the router, then you must turn o your modem, disconnect the USB cable and connect an Ethernet cable to the Internet port on the router, and then turn the modem back on. In some cases, you may need to call your ISP to change connection types (USB to Ethernet).

If you have DSL and are connecting via PPPoE, make sure you disable or uninstall any PPPoE software such as WinPoet, Broadjump, or Enternet 300 from your computer or you will not be able to connect to the Internet.

Section 2 - Installation

L7-N-R2000 User Manual

Wireless Installation Considerations

The D-Link wireless router lets you access your network using a wireless connection from virtually anywhere within the operating range of your wireless network. Keep in mind that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to follow these basic guidelines:

1. Keep the number of walls and ceilings between the D-Link router and other network devices to a minimum - each wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is minimized.

2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42 feet (14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better reception.

3. Building Materials make a dierence. A solid metal door or aluminum studs may have a negative eect on range. Try to position access points, wireless routers, and computers so that the signal passes through drywall or open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water (sh tanks), mirrors, le cabinets, brick, and concrete will degrade your wireless signal.

4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise.

5. If you are using 2.4GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and home security systems), your

wireless connection may degrade dramatically or drop completely. Make sure your 2.4GHz phone base is as far away from your wireless devices as possible. The base transmits a signal even if the phone in not in use.

Reserve:

Note: The Revoke option will not disconnect a PC with a current network session from the network; you would need to use MAC Address Filter to do that. Revoke will only free up a DHCP Address for the very next requester. If the previous owner is still available, those two devices may both receive an IP Address Conict error, or the second device may still not receive an IP Address; in that case, you may still need to extend the “DHCP IP Address Range” to address the issue, it is located in the DHCP Server section.

The Reserve option converts this dynamic IP allocation into a DHCP Reservation and adds the corresponding entry to the DHCP Reservations List.

Virtual Server

The L7-N-R2000 can be congured as a virtual server so that remote users accessing Web or FTP services via the public IP address can be automatically redirected to local servers in the LAN (Local Area Network).

The L7-N-R2000 rewall feature lters out unrecognized packets to protect your LAN network so all computers networked with the L7-N-R2000 are invisible to the outside world. If you wish, you can make some of the LAN computers accessible from the Internet by enabling Virtual Server. Depending on the requested service, the L7-N-R2000 redirects the external service request to the appropriate server within the LAN network.

The L7-N-R2000 is also capable of port-redirection meaning incoming trac to a particular port may be redirected to a dierent port on the server

computer.

Each virtual service that is created will be listed at the bottom of the screen in the Virtual Servers List. There are pre-dened virtual services already in the table. You may use them by enabling them and assigning the server IP to use that particular virtual service.

Automatic Uplink Speed:

Measured Uplink Speed:

Manual Uplink Speed:

Connection Type:

This option is disabled by default. Enable this option for better performance and experience with online games and other interactive applications, such as VoIP.

This option should be enabled when you have a slow Internet uplink. It helps to reduce the impact that large low priority network packets can have on more urgent ones.

This option is enabled by default when the QoS Engine option is enabled. This option will allow your router to automatically determine the uplink speed of your Internet connection.

This displays the detected uplink speed.

The speed at which data can be transferred from the router to your ISP. This is determined by your ISP. ISP’s often speed as a

download/upload pair. For example, 1.5Mbits/284Kbits. Using

this example, you would enter 284. Alternatively you can test your uplink speed with a service such as www.dslreports.com.

By default, the router automatically determines whether the

underlying connection is an xDSL/Frame-relay network or some

other connection type (such as cable modem or Ethernet), and

it displays the result as Detected xDSL or Frame Relay Network.

If you have an unusual network connection in which you are actually connected via xDSL but for which you congure either “Static” or “DHCP” in the Internet settings, setting this option

to xDSL or Other Frame Relay Network ensures that the router

will recognize that it needs to shape trac slightly dierently in order to give the best performance. Choosing xDSL or Other

Frame Relay Network causes the measured uplink speed to be

reported slightly lower than before on such connections, but gives much better results.

Detected xDSL:

When Connection Type is set to automatic, the automatically detected connection type is displayed here.

SPI (Stateful Packet Inspection, also known as dynamic packet ltering) helps to prevent cyber attacks by tracking more state per session. It validates that the trac passing through the session conforms to the protocol.

Select one of the following for TCP and UDP ports: Endpoint Independent - Any incoming trac sent to an open port will be forwarded to the application that opened the port. The port will close if idle for 5 minutes.

Address Restricted - Incoming trac must match the IP address of the outgoing connection.

Address + Port Restriction - Incoming trac must match the IP address and port of the outgoing connection.

If an application has trouble working from behind the router, you can expose one computer to the Internet and run the application on that computer.

Note: Placing a computer in the DMZ may expose that computer to a variety of security risks. Use of this option is only recommended as a last resort.

Specify the IP address of the computer on the LAN that you want to have unrestricted Internet communication. If this computer obtains it’s IP address

automatically using DHCP, be sure to make a static reservation on the Basic > DHCP page so that the IP address of the DMZ machine does not change.

Enable this option if you want to allow WISH to prioritize your trac.

Allows the router to recognize HTTP transfers for many common audio and video streams and prioritize them above other trac. Such streams are frequently used by digital media players.

Enables the router to recognize certain audio and video streams generated by a Windows Media Center PC and to prioritize these above other trac. Such streams are used by systems known as Windows Media Extenders, such as the Xbox 360.

When enabled, this option causes the router to automatically attempt to prioritize trac streams that it doesn’t otherwise recognize, based on the behaviour that the streams exhibit. This acts to deprioritize streams that exhibit bulk transfer characteristics, such as le transfers, while leaving interactive trac, such as gaming or VoIP, running at a normal priority.

WISH Rules:

A WISH Rule identies a specic message ow and assigns a priority to that ow. For most applications, the priority classiers ensure the right priorities and specic WISH Rules are not required.

WISH supports overlaps between rules. If more than one rule matches for a specic message ow, the rule with the highest priority will be used.

L7-N-R2000 User Manual

Wireless Security

This section will show you the dierent levels of security you can use to protect your data from intruders. The

L7-N-R2000 oers the following types of security:

• WPA2™ (Wi-Fi Protected Access 2) • WPA2-PSK (Pre-Shared Key)

• WPA™ (Wi-Fi Protected Access) • WPA-PSK (Pre-Shared Key)

What is WPA?

WPA, or Wi-Fi Protected Access, is a Wi-Fi standard that was designed to improve the security features of WEP (Wired Equivalent Privacy).

The 2 major improvements over WEP:

• Improved data encryption through the Temporal Key Integrity Protocol (TKIP). TKIP scrambles the keys using a hashing algorithm

and, by adding an integrity-checking feature, ensures that the keys haven’t been tampered with. WPA2 is based on 802.11i and uses Advanced Encryption Standard (AES) instead of TKIP.

• User authentication, which is generally missing in WEP, through the extensible authentication protocol (EAP). WEP regulates

access to a wireless network based on a computer’s hardware-specic MAC address, which is relatively simple to be snied out and stolen. EAP is built on a more secure public-key encryption system to ensure that only authorized network users can access the network.

WPA-PSK/WPA2-PSK uses a passphrase or key to authenticate your wireless connection. The key is an alpha-numeric password between 8 and 63

characters long. The password can include symbols (!?*&_) and spaces. This key must be the exact same key entered on your wireless router or access point.

WPA/WPA2 incorporates user authentication through the Extensible Authentication Protocol (EAP). EAP is built on a more secure public key encryption

system to ensure that only authorized network users can access the network.

if you are having problems. (The examples below are illustrated in Windows computer will look similar to the following examples.)

1. Why can’t I access the web-based conguration 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

XP. If you have a dierent operating system, the screenshots on your

• Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a dierent cable or connect

to a dierent port on the device if possible. If the computer is turned o, the link light may not be on.

• Disable any internet security software running on the computer. Software rewalls such as Zone Alarm, Black Ice, Sygate, Norton Personal Firewall,

and Windows XP rewall may block access to the conguration pages. Check the help les included with your rewall software for more information on disabling or conguring 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

• If you still cannot access the conguration, unplug the power to the router for 10 seconds and plug back in. Wait about 30 seconds and try accessing

the conguration. If you have multiple computers, try connecting using a dierent 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.

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 leave the password box empty.

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 nd 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, XP, Vista® and 7 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 nd your MTU, you can now congure your router with the proper MTU size.

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 (blank by default). Click OK to enter the web conguration page for the device.

• Click on Setup and then click Manual Congure.

• To change the MTU enter the number in the MTU eld 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 oce environments, and public areas such as airports, coee shops and universities. Innovative ways to utilize WLAN technology are helping people to work and communicate more eciently. Increased mobility and the absence of cabling and other

xed infrastructure have proven to be benecial 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 oce 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 aord. 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 dierent 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, oce, business, D-Link has a wireless solution for it.

Home

• Gives everyone at home broadband access

• Surf the web, check email, instant message, and etc

• Gets rid of the cables around the house

• Simple and easy to use

Small Oce and Home Oce

• Stay on top of everything at home as you would at oce

• Remotely access your oce network from home

• Share Internet connection and printer with multiple computers

• No need to dedicate oce space

Where is wireless used?

Wireless technology is expanding everywhere not just at home or oce. 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, Coee Shops, Libraries, Restaurants, and Convention Centers.

Wireless network is easy to setup, but if you’re installing it for the rst 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

signicantly reduce any interference that the appliances might cause since they operate on same frequency.

Security

Don’t let you next-door neighbors or intruders connect to your wireless network. Secure your wireless network by turning on the WPA 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 L7-N-R2000 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 Search box.)

At the prompt, type ipcong 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 rewall software programs may block a DHCP request on newly installed adapters.

If you are connecting to a wireless network at a hotspot (e.g. hotel, coee shop, airport), please contact an employee or administrator to verify their wireless network settings.

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 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 D-Link 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.

7 - Click on Start > Control Panel > Network and Internet > Network and Sharing Center.

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.
