Before calling Customer Support
Make a note of the following answers before calling customer support:
● How many remote units do you have talking to each access point?
● What channels are you using, and how are they dispersed?
● How much coverage overlap is there between access points?
● How high above the floor are the access points mounted?
● What revision of Intel(R) PROSet software or other LAN software are you running?
● What other electronic equipment is operating in the same band?
● What construction materials are used in wall and floors?
Users are dropped from the wireless network
Suggested causes and solutions:
● Find out if a person or workgroup moved or if the building has been rearranged.
● If two or more users are seated too close to each other, performance can suffer. Instruct your users
to space themselves a small distance apart to keep receivers from being overloaded.
● Delivery trucks with very large metal sides can affect performance by reflecting destructive signals
back into a building. If you have an installation that includes a shipping dock, check to see if the
problem coincides with the arrival of large trucks.
● Personal “systems” can also interfere with your network. Wireless speakers, cordless earphones,
some Bluetooth devices, and similar systems can be the source of an infrequent but hard to find the
problem. Some systems do not conform to wireless regulations. Shut off suspect devices or remove
them from the area.
● If possible, remove and reinstall your new software. Conflicts with other resident software packages
are always a possibility, and they are not always the fault of the newest addition. Sometimes just
starting over fixes the problem.
● Swap units around. Does your problem follow the changed units, or is it unique to a specific
location? If it follows the product, the swapped unit could be damaged, or improperly configured. If
the problem stays with the location, try to find out what is different about that particular room or
area.
Range decreases as data rate increases
This is a normal condition. Range is inversely proportional to data rate: the faster the data, the shorter the
range. This has to do with the modulation technology used. Very fast data rates require extremely complex
signal waveforms, where even minor distortions can result in data errors. Slower data rates are much more
tolerant, and consequently will get through even in the presence of some amount of noise, interference,
distortion and echo.
Signal doesn't pass through a short or thin wall
Range is highly dependent on the physical environment. In a line-of-sight location, with elevated and
