Hidrosadenite inguinal, Kamen rider gaim point of no return mv. This will tell you signal strengths, amount of retransmissions at the WiFi layer, etc. Bf3 How to make playdough with borax, Boldt bags instructions, Parrucchiera giochi. To be able to analyze the reason of the WiFi speed changes, you might want to capure in monitor mode on another system to see the WiFi management frames. Hello, it would be not a very big deal if there would be small drop in performance. Nothing wrong in the pcap file, except of course that packets are being dropped due to the switching in WiFi speeds. Then in frame 36080 the segment that was lost is being retransmitted which stops the duplicate ack's as there are no more gaps in the data. I get a 'TCP Previous Segment not captured' warning from app side, every time, so I belive that's the breakpoint. I catch the packets both from server and the app with Wireshark (the server is deployed on a remote Windows Server 2008 R2). All the following data packets are triggering a duplicate ACK as that is the way TCP tells the other side there is still some data missing.

But if there are not many http requests at the same time, the bug will likely not happen. This is probably caused by the switch to a lower bandwidth in the middle of sending a packet. In your screenshot (please supply a network capture file next time, it makes analyzing so much easier), frame 36036 mentions that a segment of the TCP stream is missing. Why the WiFi adapter continuously changes its speed is something I can not answer, but the "TCP previous segment not captured" and "TCP dup ACK" messages can be explained.
