Keep in mind, however, that the number and thickness of walls, ceilings or 
other objects that the wireless signals must pass through may limit range. 
Typical ranges vary depending on the types of materials and background RF 
(radio  frequency)  noise  in  your  home  or  business.  The  key  to  maximizing 
range is to follow these basic principles: 
1.
  
Keep the number of walls and ceilings between the Access Point and 
your receiving device to a minimum - each wall or ceiling can reduce 
your C54U’s range from 3-90 feet (1-30 meters.) For some businesses or 
for a large residential home deployment, it may be beneficial to have 
more than one access point with overlapping coverage. 
2.  Be aware of the direct line between Access Points and computers with 
wireless adapters - a wall that is 1.5 feet thick (.5 meters), at a 45-
degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree 
angle it looks over 42 feet (14 meters) thick! Try to make sure that the 
Access Points and adapters are positioned so that the signal will travel 
straight through a wall or ceiling for better reception. 
3.  Building materials make a difference - a solid metal door or aluminum 
studs may have a negative effect on range. Try to position Access 
Points, and computers with wireless adapters so that the signal passes 
through drywall or open doorways and not other materials. 
5.  Keep the C54U away (at least 3-6 feet or 1-2 meters) from electrical 
devices or appliances that generate extreme RF noise.  
For the average residence, range should not be a problem. If you 
experience low or no signal strength in areas of your home that you wish to 
access, consider positioning the Access Point in a location directly between 
the computers with wireless adapters that will be connected. Additional 
Access Points can be connected to provide better coverage in rooms where 
the signal does not register as strongly as desired.
