Placement of Wireless Components
The following placement recommendations will help you achieve the best wireless
range, coverage, security, and connection speed from your wireless devices:
O
Place wireless components in direct line of sight to one another, if possible.
O
If you notice poor signal strength on a notebook adapter, try moving your laptop
computer by just a few inches in any direction. Because of the way in which radio
waves travel, small areas within the network range sometimes receive poor
coverage.
O
Place wireless components on desks or shelves when possible (instead of on the
floor) to avoid obstacles and achieve better reception on the upper stories of
buildings.
O
Avoid placing wireless components in a way such that large, solid objects block the
direct path between them. Building components, such as fireplaces, concrete or
masonry walls and floors, metal framing, UV window film, and metallic paint will
reduce radio signal strength.
O
Avoid placing wireless components next to large metal objects such as computer
cases, monitors, and appliances. Metal objects reduce signal strength.
O
Avoid placing wireless components close to electromagnetic devices, especially
those with frequencies in the 2.4-gigahertz (GHz) range. Devices such as cordless
phones, microwave ovens, radios, and televisions can interfere with wireless
transmission.
O
If you notice poor connection speed in an area, try moving your wireless
components closer together. Connection speeds will be slower if your wireless
components are very far apart from each other on the network.
O
Be aware that wireless signal range, speed, and strength can be affected by
interference from neighboring wireless networks and devices.
Adjusting the Antenna
To improve wireless reception, you can adjust the external antenna of the USB
adapter. Start with the antenna pointing straight up, and adjust the antenna if you
experience poor signal strength. Certain areas, such as directly below the antenna, get
relatively poor reception. Pointing the antenna toward another wireless component
does not improve reception.
Note The wireless notebook adapter’s internal antennas are not adjustable.
