I followed the tutorial provided at Nexmon CSI Getting Started to capture WiFi packets on my Raspberry Pi 4B (8GB) using Nexmon.
After capturing the packets, I opened the output.pcap file in Wireshark. The captured packets display correctly, but when I apply a filter to show only Beacon frames (wlan.fc.type_subtype == 0x08), no packets are displayed.
Below is a screenshot of my Wireshark window showing the captured packets before applying the filter:
After applying the filter:
I have confirmed that the interface was in monitor mode and packets were captured correctly. Other packet types are visible in Wireshark, but Beacon frames are not shown when the filter is applied.
Please let me know if you need any additional information or if there are any steps I should follow.
Environment: Raspberry Pi 4B (8GB) Raspbian GNU/Linux 11 (bullseye) Kernel version: 5.10.92-v7l+
