Hello, Christian - thanks for the pointer to the function that sets the keys on the AR9170. I am still figuring out how to use 64 clients with h/w encryption on the AR9170 - enabling debug/tracing in my build isn't as straightforward as suggested by the wiki. However, I did find some very helpful information in the debug files in 'debugfs' including the number of retries. The current value is 4 for long packets and 7 for short packets. I think the small # of retries for regular data packets may be one reason why I am seeing some throughput problems at longer ranges. How do I change the number of retries for long packets? Is this a build-time configuration or can I change it at run-time?
