Subject: Bug with monitor mode on Intel 7260 AC
Date: Fri, 18 Oct 2013 12:23:00 +0000 (UTC) [thread overview]
Message-ID: <loom.20131018T142140-263@post.gmane.org> (raw)
I'm using Intel 7260 AC with this driver:
https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.11-rc3/ ,
with the "iwlwifi-7260-7.ucode" firmware. I'm using it in monitor mode to
capture 802.11ac packets on channel 36. It works well, I can capture VHT
packets without problems, but only as long as the number of packets per second
being captured is relatively low, e.g. 10 or 20 packets per second. As soon as
the traffic gets heavier, e.g. 100 packets per second, the card stops
capturing *all* VHT packets within a second from the moment the traffic volume
got higher. The interesting part is that it doesn't stop capturing altogether:
it keeps on capturing 802.11n HT and legacy 802.11a packets, it just
completely ignores 802.11ac VHT packets. Is there any way to fix this problem
and ensure stable VHT capture?
