Hey,
I am using Cisco 350 drivers downloaded from their
website and not something that comes with kernel. Do
you think this is the problem I am having when I use
the card in promiscuous mode? Because otherwise there
is no problem at all. Say for example, when I am on
internet working as a normal user. Also, I have tried
to put Cisco 350 card in RFMON mode but it didn't
work. Thanks a lot.
