Hello everyone 
please can anyone help me on this problem,
i want to sniff packets over my wireless connection for my final assignment , i have 3 RB192 MikroTik with point to multipoint connection and Nstreme mode = enabled, their positions are, one for AP Bridge and the others are for Station, because this is only “simulation”, distance is not count and shortly they’re all connected (i checked with ping command, and it; works),
my problem’s when i use sniffer on one of them, wlan interface is going down (the R status is gone), but when i stop it, it back into “R” status, is it normal? When i type this command : interface wireless sniffer packet> pr, the results : only beacon , data (a lot) and probe req can be found. As far as i know, with 802.11 media access mechanism, i should found the ACK type of the packet when my communication succesfully hear between two points (ex : AP and Station)
This is the real problem 
:
only beacon , data (a lot) and probe req can be found, and as RefMan for the sniffer, RefMan wrote that there’re the other type of packets like : assoc-req | assoc-resp | reassoc-req | reassoc-resp | probe-req | probe-resp |beacon | atim | disassoc | auth | deauth | ps-poll | rts | cts | ack | cf-end | cf-endack | data | d-cfack |
d-cfpoll | d-cfackpoll | data-null | nd-cfack | nd-cfpoll | nd-cfackpoll
can anyone help me how to show the other type pf packets with my connection? My purpose is to show that RTS/CTS, ACK, and the important one, i want to show PCF (client polling with Nstreme) process, i think that should have a ps-pollcf-endcf-endackd-cfackd-cfpold-cfackpollnd-cfpollnd-cfackpoll, i have already check my Nstreme status for three of them (one AP, 2 Station) and it totally works… please anyone…help me
