The Wireshark Wiki at https://wiki.wireshark.org/ provides a wide range of information related to Wireshark and packet capture in general. You will find a lot of information not part of this user’s guide. For example, it contains an explanation how to capture on a switched network, an ongoing effort to build a protocol reference, protocol-specific information, and much more.
And best of all, if you would like to contribute your knowledge on a specific topic (maybe a network protocol you know well), you can edit the wiki pages with your web browser.

Before reporting any problems, please make sure you have installed the latest version of Wireshark.
When reporting problems with Wireshark please supply the following information:
|Don’t send large files|
Do not send large files (> 1 MB) to the mailing lists. Instead, provide a download link. For bugs and feature requests, you can create an issue on Bugzilla and upload the file there.
|Don’t send confidential information!|
If you send capture files to the mailing lists be sure they don’t contain any sensitive or confidential information like passwords or personally identifiable information (PII).
When reporting crashes with Wireshark it is helpful if you supply the traceback information along with the information mentioned in “Reporting Problems”.
You can obtain this traceback information with the following commands on UNIX or Linux (note the backticks):
$ gdb `whereis wireshark | cut -f2 -d: | cut -d' ' -f2` core >& backtrace.txt backtrace ^D
If you do not have gdb available, you will have to check out your operating system’s debugger.
Email backtrace.txt to wireshark-dev[AT]wireshark.org.
The Windows distributions don’t contain the symbol files (.pdb) because they are very large. You can download them separately at https://www.wireshark.org/download/win32/all-versions/ and https://www.wireshark.org/download/win64/all-versions/ .
