wpa_supplicant: WPS Support-WSC_NACK packets

Hi,

I have Checked all the Packet Fields w.r.t Registrar-Nounces and Enrolee- Nounces with previous messages M2 and M1 with M3
But all are looking fine.
And also I observed no configuration errors w.r.t  M3 messages before returning WSC-Nack message from Router.
My Questions are

1.       What are the possible cases for router or registrar returning WSC-Nack messages?

2.       Is there any Router specific like it doesn't support WPS or having any broken implementation[Using Dlink Dir-601]

 Wireshark log w.r.t config error at M3 message: [10 09 00 02 00 00 ]

+ Configuration Error :No Error (0x0000)

Regards
Hari

Did you check which Configuration Error value is used in the WSC_NACK message?

Hi

Through supplicant I'm trying to establish WPS connection using RAlink wifi dongle.
But It was unsuccessful and if we check Packet captures its going upto  M3 packet after M3 router is returning WSC_NACK packets and dongle inturn responds with WSC_NACK packets.
So can I know wht will be the reason for WSC_NACK PACKETS from Router.
