ral0... I guess that's a Ralink card. Another guess, but is it a USB  
one? I have a Linux netbook with a built-in USB ralink card. For it to  
work properly with hostapd, I have to wait for the rt2x00 driver  
developers to implement USB acks. Which, fun fun, apparently requires  
changes to the USB stack on Linux.

The reason your message seems the same to me even though m0n0 is  
BSD-based is because I get the exact same messages from hostapd when  
it has trouble, and only with WPA/WPA2. I haven't looked into the  
status of Ralink drivers on BSD but I bet you'll find it's the same  

For me it fixed the problem to lower the encryption to WEP, which is  
of course woefully insecure. I threw a MAC address filter on for some  
more somewhat ineffective security. (another effect of the  
work-in-progress Linux drivers is no antenna control, so it doesn't  
work outside my house anyway ;-)

I suggest you somehow script m0n0 to do this for you, automatically ;-)

Hope this helps.
