I was searching for a WiFi 11ac sniffer which can work on Ubuntu. I have tried Intel AC-7260 and Broadcom 4352, Both MiniPcie Form factor cards. With Intel I was able to get the latest firmware and able to sniff. But, it does not sniff if the packets are LDPC encoded other wise it sniffs 1 & 2 spatial stream data. I used 3.15 kernel on Ubuntu 12.04 LTS.
With Broadcom, though I have taken latest "wl" driver from their web site, I could not set it monitor mode, which I have posted a query at Monitor Mode on broadcom 6.30.223.248 wl driver does not work
Any one has tried anything else or using already please share your ideas.

The reason why Intel AC 7260 does not sniff LDPC packets is because it has H/W issues with LDPC. Intel claims it is fixed in next H/W AC7265.
In station Mode, though it connects by advertising LDPC support, there is a lot of packet loss, so disable LDPC to get it working.
