TOTAL NETWORK SECURITY
The Xtreme N®450 Dual Band Gigabit 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 standards ensure that you’ll be able to use the best possible encryption
method, regardless of your client devices. In addition, this Xtreme N®450 Dual Band Gigabit Router utilizes dual active firewalls (SPI and
NAT) to prevent potential attacks from across the Internet.
* Maximum wireless signal rate derived from IEEE Standard 802.11g and 802.11n specifications.Actual data throughput will vary. Network conditions and environmental
factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data throughput rate. Environmental conditions
will adversely affect wireless signal range.

Section 1 - Product Overview
• Faster Wireless Networking - The DIR-665 provides up to 450Mbps* 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 650% faster than 802.11g.
• Compatible with 802.11g Devices - The DIR-665 is still fully compatible with the IEEE 802.11g standard,
so it can connect with existing 802.11g PCI, USB and Cardbus adapters.
• Advanced Firewall Features - The Web-based user interface displays a number of advanced network
management features including:
• Content Filtering - Easily applied content filtering based on MAC Address, URL, and/or
Domain Name.
• Filter Scheduling - These filters can be scheduled to be active on certain days or for a
duration of hours or minutes.
• Secure Multiple/Concurrent Sessions - The DIR-665 can pass through VPN sessions. It
supports multiple and concurrent IPSec and PPTP sessions, so users behind the DIR-665
can securely access corporate networks.

Section 2 - Installation
Before you Begin
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.
Please configure 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 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.

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 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
since 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 2.4GHz 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.
