Wireless Coverage problem

Hi All,

                I have 1 WLAN controller 2112 and 10 APs 1242G with external antennas and I’m facing a problem in the coverage, as while standing directly under any AP (about 4 meters far) without any obstacles in-between the signal received at the hand held device is good and when moving little a bit away the signal decreases to fair and poor while by using a cheap stand alone Linksys AP in the same place the signal in the hand held is excellent which is normal due to the small distance.

additionally

·         The antennas are two dipole antennas in each AP with Omni directional radiation pattern.

·         The antennas are oriented vertically and perpendicular to the AP body.


So anyone has any reasons or solution for this situation ?, maybe there are some settings in the controller can make the AP optimized for coverage distance or something like this, please advise.

Don't know what external antennae you have but do you know what the horizontal and vertical azimuth is like?

The 4941 is for 2.4 Ghz.  As you know, there are only three non-overlapping channels on this frequency.


What's the coverage like on the 5.0Ghz?
