Adjusted channel settings through Wireshark's wireless toolbar to match the channel my AP is broadcasting on (7).Tried different target devices (Iphone, Windows 10 Desktop).Connect to AP after putting device into Monitor mode (which I think just switched the interface to Managed as I was then only able to see my traffic).

Create wlan0mon interface with airmon-ng and listen on that instead (using sudo airmon-ng start to create the virtual interface wlan0mon and used that as my listening interface in Wireshark).On the client Pi I am connected to the AP and running a script that periodically curls the Apache server on the AP.

Start wireshark, check the monitor mode checkbox, restart wireshark, and then begin capture. The set up on my sniffing system has been: ifconfig wlan0 down It is set to run 802.11g with no security. I configured HostAPD to use my Raspberry Pi as an access point. I am running Wireshark on Kali Linux attempting to sniff wireless traffic.

I can see Probes, Beacons, Acknowledgements, Request-to-sends, Clear-to-sends, and null data frames but not any non-null data. I've seen this question a few times before but none of the posted solutions solved my issue.

Turn on wireshark packet sniffer
