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...
From my understanding, only the initial ath9k offerings (AR5416 on
pci/whatever the PCI-E Equivalent is), supported < 20mhz
operation.
