EAP/TLS DLINK DWL-2000AP+ Setup Problem XP Client

[Ceyhun K�]

Hi,

I've setup eap/tls with freeradius in my network.
I'm using certificates signed by a private CA.

Here is my problem:

When i check validate server certificate in client's connection
properties, radius an access challenge and nothing happens:

Sending Access-Challenge of id 3 to 192.168.145.13:1812
        EAP-Message =
0x010400350d800000002b14030100010116030100209e7c62b412a95e4583fd662183c3cfd5ff3aa01d4cf27de813dc6cc9b040fc78
        Message-Authenticator = 0x00000000000000000000000000000000
        State = 0xf48deff8e489ad47d9acb4c64dc756f4

With box unchecked, everything seems to be ok in freeradius logs.
But just after Access-Accept packet, AP reboots and client connection dies.

I'm confused, where to find error?
My AP HW, freeradius configuration, or certificate stuff.

Please guide me.
