The Roaming not work, and users disconnect constantly even not move around.
I have a network with 16 AP (10 R500 and 6 R300) and a 1200 controller,2 SSID with WPA/AES and i need use a softphone but i have the next issue with some users:
All the Iphone ́s was disconnect constantly
An a Samsung Note 4 lost wifi signal and block the wifi networks when it moves of a R500 to a R300 (We need to turn on and off the airplane mode to resolve the issue)
More than 10 users with laptops HP and wireless card ralink rt3290 can not connect with the network (i upgrade the drivers and some laptops can connect now but the navigation on the net was terrible slow)
When i walk through the office and change of one AP to another and if i am in a call this ends, and the use of softphone it is very important in this project.
I hope anyone can help me.
