Hello, I am trying to capture packets that are exchanged between an AP and a smartphone on the 5Ghz frequency. For generating traffic, I upload UDP traffic from a laptop PC towards the smartphone using iperf. The problem is that I can see _only_ the control frames like RTS/CTS, Block ACK, while the data packets are not captured. I uploaded the Wireshark capture files at [1] (located inside the folders whose name starts with 5Ghz). If I use the 2.4 frequency, all the frames are captured. I also uploaded the Wireshark packet traces for 2.4Ghz at [1] (located inside the folders whose name starts with 2.4 Ghz). Is this a known bug or am I doing something wrong?
