Hey folks,

Recently I've been trying to find an issue with my WiFi that runs on 5ghz using a Mac running Wireshark 2.0.3. Whenever I do a capture with I am only getting 2.4ghz traffic. If I run a capture manually in terminal using airport en0 sniff (channel) I can get the 5ghz traffic I want. Is there any way to specify what channel Wireshark captures on or allow it to capture 5ghz traffic along with 2.4ghz traffic?

You have to set the channel manually after disconnecting from an active network. Easiest way I found was the following tool:

Alternatively, if you find these executables on the system,

(to disassociate)

sudo airport -z

(set channel 36, for instance, on 5GHz)

sudo airport --channel=36

I start Wireshark with monitor mode enabled on the wifi adapter to collect packets.
