Supplicant Authentication in raidus.

Hi, I installed freeRadius and configured EAP-peap. I used hostapd as NAS. When supplicant connects to nas. It asks for username and password. On filling those there is a serious communication between radius and nas. Finally radius sends accept packet to nas. But my supplicant is not able to connect to the network. It keeps sending connection request. How to connect my device to nas after a single authentication. Thanks.
