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 -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
