I have 4402 controller with 1142 Wireless Access Points installed. Access Points are deployed in a building . As I connect to a SSID and move to a different floor, I dont see the access point connected to the second floor, it still connects to the same older floor and with less signal. Is there any tweaking to be done on the controller for roaming in such a way , when the user moves , this connects to a better access point with good signal. Customer is not happy with the idea of disconnecting the SSID and reconnecting it as it connects to the nearer access point.
