A great way to get the most out of Wireshark is to create Configuration Profiles. These profiles allow you to save configuration settings and filters based on protocol or application. By customizing the columns, colorization rules, and filters for a protocol, you can quickly get down to those packets that are part of the problem.
Edit -> Configuration Profiles will get you to the dialog where you can create your own profile. Any configuration changes will be specific to that profile. You will see your new profile name appear in the lower right corner of the screen. Clicking on the name will display a list of available profiles.
Once created, these profiles may be copied from one computer to another. This is a great way to share your work with others in your group!
