wpa_supplicant 0.7.2 not passing dhcp after WPA association

[Kelly Hogan]

Hello,

We have been using wpa_supplicant to do wpa connections to standard APs.   Our latest build under openwrt backfire, we see dhcp requests failing to get a response.

Setting a static IP to the bridge yields success and traffic flows fine.    We have tried udhcpc and dhcpcd and both time out.

Connecting to a hostapd AP we can see the dhcp requests on its ingress i/f, and see its response, but on the station side we only see the request leave.

Other stations (our macs) connect to the APs fine.

Is there any known issues or any ideas on how to resolve?

Thanks in advance...  Were stumped...
