.. and basically, once you've grabbed some hostapd debugging, let me know if you see transmit queue stalls. Yes, the queue handling w/ power-save handling in hostapd mode is rather suboptimal. That's high up on my 'broken stuff that needs fixing' list. Let me know how the data gathering goes and we'll submit a separate PR for this. Thanks! adrian
