firewalls (SPI and NAT) to prevent potential attacks from across the Internet.
* Maximum wireless signal rate derived from IEEE Standard 802.11g and Draft 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 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, 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 2.4GHz 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.
