Introduction
ULTIMATE PERFORMANCE
The D-Link Wireless N300 Cloud VPN Router (DIR-640L) is a 802.11n compliant device that delivers real world performance of up to 14x
faster than an 802.11g wireless connection (also faster than a 100Mbps wired Ethernet connection). Create a secure wireless network to
share photos, les, music, video, printers, and network storage throughout your home. Connect the DIR-640L router to a cable or DSL
modem and share your high-speed Internet access with everyone on the network. In addition, this Router includes a Quality of Service
(QoS) engine that keeps digital phone calls (VoIP) and online gaming smooth and responsive, providing a better Internet experience.
EXTENDED WIRELESS COVERAGE
Powered by Wireless N technology, this high performance router provides superior home coverage throughout your home while
reducing dead spots. The router is designed for use in bigger homes and for users who demand higher performance networking. Add a
Wireless N
TOTAL NETWORK SECURITY
The Wireless N router supports all of the latest wireless security features to prevent unauthorized access, be it from over the wireless
network or from the Internet. Support for WPA/WPA2 standards ensure that you’ll be able to use the best possible encryption method,
regardless of your client devices. In addition, this router utilizes dual active rewalls (SPI and NAT) to prevent potential attacks from
across the Internet.

Section 1 - Product Overview
• Faster Wireless Networking - The DIR-640L provides up to 300Mbps* wireless connection with other 802.11n
wireless clients. This capability allows users to participate in real-time activities online, such as video streaming,
online gaming, and real-time audio. The performance of this 802.11n wireless router gives you the freedom of
wireless networking at speeds 14x faster than 802.11g.
• Compatible with 802.11b/g/n Devices - The DIR-640L is still fully compatible with the IEEE 802.11b, 802.11g,
and 802.11n standards, so it can connect with existing 802.11b, 802.11g, and 802.11n PCI, USB, and Cardbus
adapters
• Advanced Firewall Features - The Web-based user interface displays a number of advanced network
management features including:
• Secure Multiple/Concurrent Sessions - The DIR-640L can pass through VPN sessions. It supports
multiple and concurrent IPSec and PPTP sessions, so users behind the DIR-640L can securely access
corporate networks.
Features
• User-friendly Setup Wizard - Through its easy-to-use Web-based user interface, the DIR-640L lets you control
what information is accessible to those on the wireless network, whether from the Internet or from your company’s
server. Congure your router to your specic settings within minutes.

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 congure 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 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
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 dierence. A solid metal door or aluminum studs may have a negative eect 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.
