Hello, I am using a TL-WN722N for a Wi-Fi ToF project; the SOC is AR9271 and I obtained the ath9k_htc source code via backports version 3.17.1-1. For ToF measurements, the higher the clock rate of the SOC, the better, and I know that AR9271 has a 117 MHz one. Reading through the code, in file ath/ath9k/hw.c, function ath9k_hw_set_clockrate [1] there is no entry for AS_SREV_9271, leaving the clockrate to be 44MHz in the common structure and throughout execution. The 117MHz setting is done later in the code by writing to a registry [2].
I am wondering why the writing to the registry is not reflected in the common structure as well. [1] https://github.com/torvalds/linux/blob/master/drivers/net/wireless/ath/ath9k/hw.c#L39 [2] https://github.com/torvalds/linux/blob/master/drivers/net/wireless/ath/ath9k/hw.c#L864 Thanks, Adrian
