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.
Thanks in advance,
Aseem

ath9k_htc currently doesn't support survey dump.

Currently, no.

You can always write a patch. :)

Sujith,
Appreciate the quick response.
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.
