In monitor mode card does not transfer any frames, it only listens, so
scanning while in monitor mode is out of question.
Here are some of my observations while in monitor mode.
APs is on channel 11 and i was able to capture frames of this channel
no. 11 on every channel from 4 onwards to 11 on the other card in
Monitor mode. So may be in Monitor mode card tries to captures frames
from channels as far as it can though more far the channel is less
number of frames it captures.
It would be interesting to see that when card is in managed mode,
whether it collects frames from other channels which are 5 or more
channels apart from its own channel.
I dont know how to collect frames with 802.11 headers while in managed
mode. or if it is possible?
