So I would always use filter ‘wlan.rm.action_code = 4 or wlan.rm.action_code = 5’ like the image below. If you want to see only Responses you can use filter ‘wlan.rm.action_code = 5’.īut to me, you might as well look at both Requests and Responses together. So if you just want to see Requests you can use filter ‘wlan.rm.action_code = 4’ (remember noting the Action Code earlier?). The field name in Wireshark is ‘wlan.rm.action_code’. So, how do you filter your thousands of frames so you can easily find these Neighbour Requests and Responses? It is possible to expand the BSSID Information field and see things like if QoS and APSD are enabled on that BSSID. The Response contains a bunch of potential BSSID’s (AP’s) the client could Probe for. You can also tell the SSID the Request was for specifically.Īnd here is the Neighbour Report Response from the AP. You can see it is an Action frame with an Action Code of 4. Here is a the contents of the Neighbour Request frame. You can also tell which SSID the Request was for as well. Notice the actions frames are Acknowledged by the destination. However, Neighbour Reports are a two way transaction (Request+Response), unlike most Action frames, so they can be easier to spot when scrolling through. You won’t see anything about Neighbour Reports in the standard Wireshark view. They can be hard to spot because the frame type is an Action frame. Here is a Neighbour Report Request going out from a client and the Neighbour Report Response coming back from the AP. Note: I will now revert to the queens English and return the U’s into the word Neighbour. I then did way too much thinking and realised I should put them into a blog post. While I had the opportunity I thought it would be useful to grab the Wireshark filter for them. I was looking through a packet frame capture today and noticed some Neighbor reports for the first time.
