Try ethtool stats maybe? That should work for at least some drivers. Thanks, Ben On 11/20/2017 09:46 AM, Grégoire Gentil wrote:
My question is summarized here: https://stackoverflow.com/questions/47398018/hostapd-how-to-know-the-frequency-of-ap-mode "On Linux, I'm using hostapd in AP mode. In other words, the system is the hotspot. I would like to know what is the frequency of the Wi-Fi via c code (or a bash script that I could translate to c code). The following code which queries the kernel, only works in normal mode. It fails in AP mode. ioctl(net_sock, SIOCGIWFREQ, &wrq); In bash, I have tried: iwconfig iw dev but it doesn't report the frequency of the Wi-Fi. Same problem: it only reports in normal mode when the system associates to a router but nothing in AP mode. How can I query hostapd to know the frequency hostapd is using or is configured to use?"
