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?

Additional details:
Wi-Fi card:  iwlwifi 0000:04:00.0: Detected Intel(R) Dual Band
Wireless N 7260, REV=0x144
Firmware version: iwlwifi 0000:04:00.0: loaded firmware version
25.228.9.0 op_mode iwlmvm
Traffic encryption: WPA & WPA2 Personal
Setting up the card in wireless mode:
ip link set dev wlan0 down
iw wlan0 set type monitor
ip link set dev wlan0 up
iw wlan0 set freq 5240
