I applied a filter in wireshark to display only the incoming packets to my PC. When I save the filtered/displayed packets to a .csv file, I actually saves all the packets (un-filtered). How can I save only the displayed/filtered packets?
Exporting data
Just select Displayed in the Packet Range frame.
Note that with newer builds of Wireshark for Windows, this is available only with "Export Specified Packets", not with "Save" or "Save as" options.
