Hi,
I have a DNMA92 mini-pci wireless card (http://pcengines.ch/dnma92.htm) and
I'm using it with two antennas on the 2.4Ghz band (802.11b/g).
This is the output of lspci -vv

Kernel driver in use: ath9k

I'm using Ubuntu 10.10 with kernel 2.6.35-23-generic and with the ath9k
module of 2.6.36 backported to 2.6.35 (with the package
linux-backports-modules-compat-wireless-2.6.36-2.6.35-23-generic)

parm: nohwcrypt:Disable hardware encryption (int)
parm: blink:Enable LED blink on activity (int)
I'm wondering if the channel diversity mechanism is exploited by the ath9k
driver and by my DNMA92 wireless card.. If it is supported, is there a way
to query the network card
and to understand if antenna 1 or 2 is being used?
Thank you in advance for any help!

no idea...I dont think we have any direct commands to understand
antenna 1 or 2 is used.Antenna diversity is only there for AR9285
