in experimenting with writing antenna control for ath9k from user nl80211 user space found experimentally, verified with several R52n miniPCI ar9220 boards, that the current ath9k does not transmit on antenna B but does receive. Only on antenna A association/authentication and communication is possible. Have tried all sorts of settings for registers $8004 (AR_STA_ID1) masks 200000/40000/80000/400000 and $8058 (default antenna) and enabling/disabling ccmp and cck diversity but cannot get antenna B to transmit. What is the proper way to switch between 1) mimo 80211.n operation and 2) single antenna no-diversity operation, or 3) sectored operation giving all available antennas some airtime and beacons and answering on basis of best reception results ? As said current ath9k seems not to initialize the ar9220 properly for mimo mode on the R52n board that has two PAs but now only can use one. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
