Section 2 – Installation D-Link DIR-602 User Manual 9 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 configure the router with the computer that was last connected directly to your modem. • 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 off 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. • When running the Setup Wizard from the D-Link CD, make sure the computer you are running the CD from is connected to the Internet and online or the wizard will not work. If you have disconnected any hardware, re-connect your computer back to the modem and make sure you are online.
Section 2 – Installation D-Link DIR-602 User Manual 10 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, however, 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 difference. A solid metal door or aluminum studs may have a negative effect 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 (fish tanks), mirrors, file 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 2.4 GHz 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 2.4 GHz 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.

Section 3 – Configuration Firewall Settings The built-in firewall helps protect your network from the outside world. The SPI feature helps prevent cyber attacks. Sometimes you may want a computer exposed to the outside world for certain types of applications. If you choose to expose a computer, you can enable DMZ. DMZ is short for Demilitarized Zone. This option will expose the chosen computer completely to the outside world. SPI Firewall: SPI (Stateful Packet Inspection, also known as dynamic packet filtering) helps to prevent cyber attacks by tracking more states per session. It validates that the traffic passing through the session conforms to the protocol. Block WAN PING: For added security, it is recommended that you enable the Block PING WAN option. Ping is often used by malicious Internet users to locate active networks or PCs. Block IDENT: Block Identification used port 113. Port 113 is associated with the Internet's Ident/Auth (Identification / Authentication) service. When a client program in your computer contacts a remote server for services such as POP, IMAP, SMTP, or IRC, that remote server sends back a query to the "Ident" server running in many systems listening for these queries on port 113. Enable DMZ Host: 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. Enter the DMZ IP Address. 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. VPN Passthrough: Make sure VPN passthrough is enabled if you are trying to use a VPN client from behind the router. D-Link DIR-602 User Manual 38
Section 3 – Configuration Advanced Wireless Settings It is recommended that you leave wireless parameters at their default values. Adjusting them could limit the performance of your wireless network.

Section 4 – Security D-Link DIR-602 User Manual 55 InterWireless Security This section will show you the different levels of security you can use to protect your data from intruders. The DIR-602 offers the following types of security: • WPA2 (Wi-Fi Protected Access 2) • WPA (Wi-Fi Protected Access) • WEP 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-specific MAC address, which is relatively simple to be sniffed 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
Section 4 – Security D-Link DIR-602 User Manual 56 more secure public key encryption system to ensure that only authorized network users can access the network. Configure WPA-Personal (PSK) It is recommended to enable encryption on your wireless router before your wireless network adapters. Please establish wireless connectivity before enabling encryption. Your wireless signal may degrade when enabling encryption due to the added overhead. 1. Log into the web-based configuration by opening a web browser and entering the IP address of the router (192.168.0.1). Click on Setup and then click Wireless Settings on the left side and then click Manual Wireless Network Setup. 2. Next to Security Mode, select WPA-Personal. 3. Next to Cipher Type, select TKIP and AES, TKIP, or AES. If you have wireless clients that use both types, use TKIP + AES. 4. Next to Pre-Shared Key, enter a key (passphrase). The key is entered as a passphrase in ASCII format at both ends of the wireless connection. The pass-phrase must be between 8-63 characters. 5. Click Save Settings to save your settings. If you are configuring the router with a wireless adapter, you will lose connectivity until you enable WPA-PSK on your adapter and enter the same passphrase as you did on the router.

Section 6 – Troubleshooting D-Link DIR-602 User Manual 62 Troubleshooting This chapter provides solutions to problems that can occur during the installation and operation of the DIR-602. 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 screen shots 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.

Section 6 – Troubleshooting 3. Why can’t I connect to certain sites or send and receive e-mails when connecting through my router? If you are having a problem sending or receiving e-mail, 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 D-Link DIR-602 User Manual 64
Section 6 – Troubleshooting D-Link DIR-602 User Manual 65 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. 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 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 e-mail. If changing the MTU does not resolve the problem, continue changing the MTU in increments of ten.
Appendix A – Wireless Basics D-Link DIR-602 User Manual 66 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.
Appendix A – Wireless Basics D-Link DIR-602 User Manual 67 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.
Appendix A – Wireless Basics D-Link DIR-602 User Manual 68 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 has 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. Home • Gives everyone at home broadband access • Surf the web, check e-mail, instant message, and etc • Gets rid of the cables around the house • Simple and easy to use Small Office and Home Office • Stay on top of everything at home as you would at office • Remotely access your office network from home • Share Internet connection and printer with multiple computers • No need to dedicate office space
Appendix A – Wireless Basics D-Link DIR-602 User Manual 69 Where is wireless used? Wireless technology is expanding everywhere not just at home or office. The freedom of mobility it provides has led to more and more public facilities providing wireless access to attract people. Wireless connection areas in public places are usually called “hotspots”. Using a D-Link wireless adapter with your laptop, you can access hotspots to connect to the Internet from remote locations like: Airports, Hotels, Coffee Shops, Libraries, Restaurants, and Convention Centers. Wireless networks are easy to setup, but if you’re installing one 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 significantly reduces any interference that the appliances may cause due to operating on the same frequency.
Appendix A – Wireless Basics D-Link DIR-602 User Manual 70 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 the product manual for more detailed 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 DIR-602 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.
Appendix B – Networking Basics Networking Basics Checking your IP address After you install your 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 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 adapters. D-Link DIR-602 User Manual 71
Appendix B – Networking Basics 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.
