3.3 Installation Considerations

The WRT-390L 2.4GHz Wireless 802.11n(DRAFT) Giga Router lets you access your network, using a

wireless connection, from virtually anywhere within its operating range. 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 WRT-390L and other network devices to a

minimum - each wall or ceiling can reduce your wireless product’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 can impede the wireless signal - a solid metal door or aluminum studs may have a

negative effect on range. Try to position wireless devices and computers with wireless adapters so

that the signal passes through drywall or open doorways and not other materials.

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

generate extreme RF noise.

3.4 Getting Started

For a typical wireless setup at home, please do the following:

1. You will need broadband Internet access (a Cable or DSL-subscriber line into your home or

office)

2. Consult with your Cable or DSL provider for proper installation of the modem.

3. Connect the Cable or DSL modem to the WRT-390L Wireless Broadband Router (WAN

port).

4. Ethernet LAN ports of the WRT-390L are Auto MDI/MDIX and will work with both

Straight-Through and Cross-Over cable.
