Operation Guidelines

Wireless Installation Considerations

The DIR-620 device 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 noise in your home or office. To maximize your wireless range, follow the

guidelines below.

1. Keep the number of walls and ceilings between the DIR-620 device and other network

devices to a minimum – each wall or ceiling can reduce your wireless network range by 3-

90 feet (1-30 meters).

2. Be aware of the direct line between network devices. Place your devices so that the signal

travels 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 your wireless range. Try to position your router, access points, and

computers so that the signal passes through drywalls 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 router 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 equipment (wireless devices 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. Note, that the base transmits a signal even if the phone in

not in use.
