Hi ALL:
How to capture channel 2 's frames when wireless interface was set to channel 1.
Wireless card is in mode 11g.
Bandwidth is 20MHz, between channel 1 and 2 is 5MHz, 20MHz include channel 2.
So it's can capture channel 2's frames when wireless card is set in channel 1.
Is that right?
Thank you.

Hi Tao,
I don't know anything about the kernel wireless drivers. But I do
know something about RF communications, and based on that I would say
"probably not". I would be extremely surprised if it were possible to
see frames transmitted on channel 2 when the radio is tuned to channel
1.
Traffic on channel 2 could interfere with and corrupt traffic on
channel 1, but that doesn't mean you can successfully decode the
frames.
Cheers, Henry
