Hello,
I have six multiple access points with same SSID, installed within as per the site survey report.
AP Name AP Model
EBEAP001 AIR-LAP1242AG-E-K9
EBEAP002 AIR-LAP1242AG-E-K9
EBEAP003 AIR-LAP1242AG-E-K9
EBEAP004 AIR-LAP1242AG-E-K9
EBEAP005 AIR-LAP1242AG-E-K9
EBEAP006 AIR-LAP1242AG-E-K9
95-99% Clent connection goes to EBEAP006.
There are many clients which arv very near to AP1, AP2 and AP3.
Any thoughts on why this is happening ?

The clients will always be connected to AP whose signal power is best of all, if same SSID is being broadcast!!

HI Saurav,
Agree with you but this AP 6 is too far from the clients still they are connecting with it.
AP1, AP2 and AP3 are 5-10 meter far from client.
