Hi
I have an Atheros AR9160 miniPCI board, installed in my Centrino laptop
(but the laptop has only two antenna).
When I run iperf (from ports benchmarks/iperf) to test 11n, the test
cannot done. Console log says bb hang, but I can ping peer node without
problems.
I think AR9160 driver cannot work in heavy traffic loading.
