AP Roaming with RADIUS Auth WLAN

Hi,

i´ve a WLAN here with RADIUS (Certificate based) Authentication set here. I can connect to the WLAN without Problems ... RADIUS Auth works ... but when im "travelling" through my building as soon as there is some Roamin from one AP to another the Network Connection drops immediately (sometimes it reconnects after a few seconds ... sometimes not).

With WPA-PSK the Connection is stable throughout the way ...

Any Ideas whats possibly wrong here ?

Thanks and Regards

I known really late (very small word for the delay caused) , once you enable 802.11r in SSID it should work fine. 802.11r helps roaming of 802.1x users between the Access point and IEEE standard for roaming.
