I have several AirPorts(IEEE802.11AC) and setup these AirPorts at each corner of the office to support the feature of Data Romaing.
The AirPorts are connected to a Radius Server(Operation System is Centos 6.5 with freeRadius)
The setting configuration of each AirPort devices are as following:
SSID Name: PY_5G-1.
Authentication Method: WPA/WPA2 Enterprise(FT and Data Roaming enabled).
Key Secret: 12345678
Radius User Name and Password: test/test
we expect that when Wi-Fi tablet(New IPad) moving from current corner(AirPort A) to others corner(AirPort B,C,D) Wi-Fi tablet should switch to the corresponding AirPort(AirPort B,C,D). After setting up the environment and doing the test we found that Wi-Fi tablet switched to the corresponding AirPort but the feature of Data Romaing doesn't work(because in the meanwhile we captured the 4-ways handshake's packets via packet sniffer tool).
We hope to have the full user guide which should indicate how to setup the Data Roaming environment or how it works.
