WPA2 Connection Problems between Android and DLink DIR-825 running OpenWRT

Hi all,

I recently upgraded to a DIR-825 router (atk9k based), on which I've 
installed the trunk build of OpenWRT (with an early-July version of 
hostapd). I've been able to setup everything as needed, except for one 
major problem. WPA2 connections work with no problems between the router 
and a MacBook and a Linux laptop, with both radios. I cannot get a WPA2 
negotiation to complete between my Motorola Droid and the router. WPA2 
connections worked with my previous router (but which did not use 
hostapd), and I don't have any problems connecting to other wireless 
networks, both open and secured with WPA2-Enterprise. I've also tried 
enabling TKIP as well as AES, with no change, as well as changing 
htmode, again, with no change.

The configuration file for hostapd on the 2.4Ghz interface is below, 
along with a log from hostapd. Looking through the log, the problem 
appears to occur in comparing the second step of the handshake, with one 
octet being different. However, I know little about WPA2, and I'm 
wondering if anyone has any thoughts on where something is going wrong. 
Is it hostapd on the router, or wpa_supplicant on the Droid? Is it 
possible to fix with just hostapd on the router (even if it means a 
custom build)?

Thanks,
David
