I use sniffer 4.70.5 to capture traffic between server and client. And found so many "non-responsive station". I'm in doubt why it will prompt it.
On sniffer manual,it said:"The analyzer generates the diagnosis Non-responsive station (and considers a connection broken) when the number of consecutive identical retransmissions without response on a given connection exceeds the No Responses threshold in the Expert config menu."
But in my trace,data flow is like this:
source dest summary sniffer expert
a b ack=7547 seq=4650 retransmission
a b ack=7547 seq=6030 retransmission
a b ack=7547 seq=7410 non-responsive station
|->next expected seq=8790
b a ack=8790 non-responsive station
Sniffer manual said "consecutive identical retransmissions ", but these 3 frame from A to B is not identical and the ack frame from B to A doesn't retransmit.
So why sniffer will prompt non-responsive station ?
thanks!
