Is there a plan to add this functionality in ath9k_htc driver? If yes, it would be great if you can share a tentative date by when this functionality will be available. If no, then is there any other way of retrieving this information. Thanks once again. -Aseem On Tue, Apr 24, 2012 at 6:50 PM, Sujith Manoharan wrote: > Aseem Sharma wrote: >> 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.
