determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
Consult the dealer or an experienced radio/TV technician for help.

INSTALLATION CONSIDERATIONS
There are a number of factors that can impact the range of wireless devices.
1. Adjust your wireless devices so that the signal is traveling in a straight path, rather than at an
angle. The more material the signal has to pass through the more signal you will lose.
2. Keep the number of obstructions to a minimum. Each obstruction can reduce the range of a
wireless device. Position the wireless devices in a manner that will minimize the amount of
obstructions between them.
3. Building materials can have a large impact on your wireless signal. In an indoor environment, try to
position the wireless devices so that the signal passes through less dense material such as dry
wall. Dense materials like metal, solid wood, glass or even furniture may block or degrade the
signal.
4. Antenna orientation can also have a large impact on your wireless signal. Use the wireless
adapter’s site survey tool to determine the best antenna orientation for your wireless devices.
5. Interference from devices that produce RF (radio frequency) noise can also impact your signal.
Position your wireless devices away from anything that generates RF noise, such as microwaves,
radios and baby monitors.
6. Any device operating on the 2.4GHz frequency will cause interference. Devices such as 2.4GHz
cordless phones or other wireless remotes operating on the 2.4GHz frequency can potentially drop
the wireless signal. Although the phone may not be in use, the base can still transmit wireless
signal. Move the phone’s base station as far away as possible from your wireless devices.
If you are still experiencing low or no signal consider repositioning the wireless devices or installing
additional access points. The use of higher gain antennas may also provide the necessary coverage
depending on the environment.
