<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>
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.<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>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.<o:p></o:p></p>
