Hi, I have run into the following problem: When I register an external registrar with hostapd then Windows 8 cannot connect using pbc. This does not look like a bug in hostapd, the problem seems to be that Windows does not send an M2D ACK back to hostapd. Instead it just keeps sending M1 messages which will be rejected as hostapd is waiting for a M2D ACK. The sequence of messages looks somewhat like this: hostapd -> enrollee: Request identity enrollee -> hostapd: Response identity hostapd -> enrollee: Request wsc start enrollee -> hostapd: Response m1 hostapd -> enrollee: Request m2d enrollee -> hostapd: Response m1 hostapd -> enrollee: Failure Can anybody confirm this issue? If this can be confirmed, is this an issue that can be fixed for hostapd to make it work with Windows and external registrars? I have used version 2.1 but by looking at the code it seems that 2.5 has the same behaviour.
