Subject: [ath9k-devel]  Antenna Configuration

  Hi Mike,

I had the same problem and wrote a workaround for it. The possible 
Chainmask-Configuration is retrieved from the EEPROM of your card by the 
driver. Normally all Antennas are activated. There is no API for 
Antenna-Configuration in Ath9k/Cfg80211... and therefore no API in 
Userspace, too. Try to apply the attached patch. It should give you the 
possibility to set up your antenna-config by using special module 
params. I'm using an embedded system with up to four mini-pci-slots. So 
I added the params chainconf0 - chainconf3. Usage:

 > insmod/modprobe ath9k chainconf0=11:22:33:44:55:66#2x2 (3x3, 2x3, 1x1 
...)

(macadress of the interface + MIMO-representation)

I tested the patch with a spectrum analyser attached to the 
antenna-connectors and by transmitting data. The patch works well for me 
with AR9160.

good luck :-)

Robert
