We have a V2110 controller and since yesterday, clients with windows can not connect to the SSID provided by the controller.Clients with android, linux, ios, connect with no problems, but clients with windows, always refused without error.
It was working in this version by the end of last week.Since yesterday, clients (laptops and smartphones) with windows stop working.
There are some windows clients taht can connect, get IP address, but the trafic doesn't pass.
