Hello, I was previously using Cisco Aironet wireless adapter (it uses ath5k driver); using which I was able to get the survey dump using the following command: root@as75:~# iw phy phy0 interface add mon0 type monitor root@as75:~# ifconfig mon0 up root@as75:~# iw dev mon0 survey dump Survey data from mon0 frequency: 2412 MHz noise: -95 dBm channel active time: 11813 ms channel busy time: 300 ms channel receive time: 237 ms channel transmit time: 0 ms However, when I run the same commands after connecting SONY USB Wireless LAN Adapter UWA-BR100 (which internally uses ath9k_htc driver) I do not seem to get any output. Also, the command is successful (as I am running echo $? which returns ‘0’) My questions: 1. Is there any other command or proc/sys interface from where I can retreive this information? 2. Is there any other command option that I can use to retreive this information? 3. Is there a patch for the above said driver that I can use? Any help will be really appreciated.
