Set when the receive window size is zero and none of SYN, FIN, or RST are set. The acknowledgement number is equal to the last-seen acknowledgement number. The sequence number is equal to the next expected sequence number. The window size is non-zero and not equal to the last-seen window size. TCP Spurious RetransmissionĬhecks for a retransmission based on analysis data in the reverseĭirection. Set when the current sequence number is greater than the next expected sequence number. Set when the SYN flag is set (not SYN+ACK), we have an existing conversation using the same addresses and ports, and the sequence number is different than the existing conversation’s initial sequence number. The threshold is either the value shown in the “iRTT” (_rtt) field under “SEQ/ACK analysis” if it is present, or the default value of 3ms if it is not. The last segment arrived within the Out-Of-Order RTT threshold. The next expected sequence number and the next sequence number differ. The next expected sequence number is greater than the current sequence number.

I thought it would be good to pull them together in one place to make it easier for the newcomer to find the resources they may need. There are many good articles, videos and podcasts out there looking at wireless analysis, particularly if Wireshark is your tool of choice. Using Wireshark for wireless capture and analysis on Wi-Fi networks can be a little tricky and presents the newcomer with a whole new slew of frame types to learn. They may wonder if they can use Wireshark for their initial foray into wireless analysis. Many people approaching wireless analysis may already be familiar with Wireshark, based on their previous experience on wired networks, where they may have used it for troubleshooting and analysis purposes. There are a huge variety of options when considering how to capture wireless traffic over the air, with many of the solutions being paid-for options that may be out of reach for many individuals. Wireless traffic capture and analysis can be a tricky business and is often seen as something of a dark art to newcomers to the world of Wi-Fi.
