I've been pinging back and forth between a ath5k x86 system and an ath9k
MIPS OpenWRT system.
One of the things that has been ellusive is the ability to set the
actual frequency bandwidth the Atheros
chips use, to something less than 20 MHz.
In the most recent development snapshots for ath5k there are seductive
sequences of code, that seem
to indicate that this feature is making its way in to the open source
version of the Atheros driver.
I have seen references to HALF_RATE and QUARTER_RATE in some of the
ath9k driver code, but
I've also seen mention that the Atheros 9K series does not support this.
So, if anyone has some illuminating comments on this I'd like to hear
about it.
Well, I'm not interested in comments about why drop the bandwidth
down... because I obviously have
some applications that a narrower frequency bandwidth would be beneficial...
