If there had been an actual Atheros wifi chipset that was appropriate for use in our new TV box, I would now, in retrospect, describe the decision not to use it as a massive tactical error.
Since there was no such chipset (and I personally tried really hard to convince them to tell me there was one, even if it they had to lie, but they refused), I can only describe the universe as being generally a disappointment to me. Please try harder next time, universe.
(This is not really a slag against the alternate vendor we went with, who seems fine. It's just that we have to do everything twice, sigh.)
