How to capture the Broadcom 802.11n with turboQAM packet.

Hi,
I need capture my cell phone's packet, the wifi chipset is Broadcom 43455(802.11n with turboQAM). I'm using ar9107 as capture adapter, but i can't capture 802.11 data frames. Maybe the ar9107 is not turboQAM compatible.
If i upgrade my capture adapter to Omniwifi(802.11ac adapter) , can i settle the question.
Thanks!

We have never encountered turboqam packets, but if it modifies the QAM value on the same channel, there may be an issue with capture, as the Ralink Chipset in the OmniWiFiAC adapter dictates the channels that can be captured. If this modified QAM is outside the 8.0211n specification then that may be the issue.
