I used something similar, but not exactly the same.

You might try changing yours (channel, encryption, etc) to see
if it has some affect.

03:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01)

My system is 64-bit, embedded appliance sort of thing with low-power Core-i7 processor.

Station to station is much slower than wired to station, but it's
easier to set up in my test bed.  I'll try wired to station, but I'm busy
with other things today.

Thanks,
Ben
