Hi all, Can anyone advise on what rate control mechanism ath9k-rate-control is based on, as for example Atheros chipsets use Onoe, and Minstrel Rate Adaptation, from what I know is based on SampleRate. Also is there any documentation on the ath9k-rate-control algorithm, and/or can someone give a

Hi, Thanks for replying Adrian, OK, just for clarity, you are saying for 1-stream STBC NICs (AR9380/9280), when I enable STBC from hostapd, the driver only transmits in STBC (transmits multiple copies of data to each antenna) if it sending at MCSs 0-7 (1 stream rates), due to low signal quality

Hi all, I need to change parameters in, /drivers/net/wireless/ath/ath9k/init.c, such that I can modify them at runtime via debugfs. I tried to do this but the driver does not load, as I reckon init.c is called before debug.c Is there anyway to do this as there is some functions I want to

Hi, I am using STBC (Space Time Block Coding) 1 stream NICs like the AR9280.I would be very grateful someone can kindly advise on how exactly STBC(transmits multiple copies of a data across each of the antennas) works in ath9k. I ask this because when I enable STBC 1-stream, the driver seems to

Hi all, I am installing the AR9380 NIC on laptops, but some only have two UFL connectors, and thus I was wondering if using only two of the UFL antenna ports will have any negative effect or difference than installing a 2x2 NIC (AR9280 for example which has only 2 ports anyway). Please kindly
