This is a small site in the 3rd and 4th floor of the building. We deployed 3 AP's in the Third floor and 2 AP's in the fourth floor. Additionally a new AP is configured and yet to set in the fourth floor. There is no problem in the 4the floor but in the 3rd floor.
Note: Site survey is not taken by the previous engineer who setup this.
AP1 and AP3 are working fine but the AP2 is having problem. Users near the AP2 having limited connectivity problem though they are close to the AP. So thought there might be some interference and disconnected the AP1. Found it is working quite well for all the users. Though sometimes users are thrown out of the network. Still some users saying the fourth floor AP is connecting and found working fine.
Most users are using MAC. 802.11b/g clients.
Configured only single SSID "KPH-3 SAL"
