See below link that I was unable to comment. Sorry for the dupe but I have tried hard to get a satisfactory answer to this question. Upon reading the WS docs and others, I am led to believe that I can capture packets from multiple hosts (on the same AP) if my USB wireless card is in monitor mode and I have the wpa key to the Ap. That is all I'm trying to do, No hacking, just capturing packets similar to what I would get with port mirroring on a switch. Is this not true? Similar to question in the link below, I have a card in monitor mode and the wpa key, but all I get is 802.11 broadcast traffic. Is that it? Do I need to authenticate to the AP to get the traffic ONLY from my card (similar to LAN Config?) or am I missing something?
Just looked at this chipset and it is really a 2.4GHz 802.11n 1x1:1 chipset (with some features to possibly improve the Rx performance).
This means you won't get any 5GHz traffic (including 802.11n 5GHz and all 802.11ac traffic), and likely won't be able to capture much of the 802.11n 2.4GHz traffic (i.e. any traffic using more than one spatial stream will be lost). Specifically, only HT MCS data rates from 0-7 will likely be available to the chipset, while 8-15 (common - in my experience most of 802.11n traffic in 2.4GHz) and 16-23/24-31 (not common) will not.
