Hi, I have a simple problem (?), but I cannot find any answer in google and wireless.kerner.org. I use 3.16.1 kernel/backport version with ath10k/QCA9880. I want to handle freq/BW to test its performance. When I change center frequency and BW by using iw command, linux reports “command failed: Device or resource busy (-16)” as follows. $ modprobe ath10k_pci $ iw wlan0 set channel 36 HT20 command failed: Device or resource busy (-16) $ iw wlan0 set freq 5180 40 5190 command failed: Device or resource busy (-16) $ iw wlan0 set freq 5180 80 5210 command failed: Device or resource busy (-16) Curiously if anyone else has solution for this problem? Thank you. -- Okhwan Lee -- 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
