Wireless Performance 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.

SSID: Service Set Identifier, which is a unique name shared among all wireless clients in
a wireless network. The SSID must match the wireless access point or router’s SSID that
you are connecting to.
Network Type:
● Infrastructure – to establish wireless communication with the LAN and other
wireless clients through the use of Access Points or Wireless Router. This is most
common type of connection.
● Ad-Hoc –to establish point-to-point wireless communication directly with other
