Re: Poor athn wireless performance

Hi Otto,

Thanks for all of the testing and information!

These are much better figures than what I have been seeing.

Fast isn't realy an important thing for me. Faster is nice, but usable
is the main thing.

I swapped out my ath card for a iwn card. It works great now, 20Mbit/sec
in both directions. So no issues with the antennas on this laptop.

Not sure why that card was performing so poorly for me. I recall having
poor ath performance on FreeBSD as well. Not sure if it's chipset
specific, or maybe related to my AP?
