The following are some general wireless tips to help minimize the impact of interference within an
environment.
Assign your network a unique SSID
Do not use anything that would be identifying like “Smith Family Network”. Choose
something that you would easily identify when searching for available wireless networks.
Do not turn off the SSID broadcast
The SSID broadcast is intended to be on and turning it off can cause connectivity issues.
The preferred method of securing a wireless network is to choose a strong form of encryption
with a strong and varied encryption key.
Change the channel
Most wireless access points and routers are defaulted to channel 6. If you have a site survey
tool that will display the channels you can plan your channel selection around neighboring
access points to minimize interference from them. If your site survey tool does not display
the channel try using channels 1 or 11.
If you are using 802.11n you should be securing the network with WPA2 security.
Please also make sure that the wireless hardware is not placed in any type of shelving or
enclosures.
Avoid stacking hardware on top of each other to prevent overheating issues
Maintain enough free space around the hardware for good ventilation and airflow. There
should also be plenty of free space around the antennas to allow the wireless signal to
propagate.
There are a number of other environmental 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.
Note: after setting up the SSID, encryption type and encryption key/passphrase, please
make a note of them for future reference. You will need this information to connect your
wireless computers to the wireless router/access point.
Note: Due to Wi-Fi certification considerations if you choose WEP, WPA or WPA2-TKIP
encryption this device may operate in legacy wireless mode (802.11b/g). You may not get
802.11n performance as these forms of encryption are not supported by the 802.11n
specification.
Wireless Tips

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, HAM radios, Walkie-Talkies 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 signals. 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.
