List at least three ways to do this in Wireshark?
When network engineers are diagnosing a problem with a connection, it often helps to filter out unrelated traffic and follow the data through the troubled connection. List at least three ways to do this in Wireshark?
This sounds like a homework assignment to me. You might want to put in some effort to find out yourself, it's not that hard.
its a homework, kinda complicated for me..
Maybe read the Wireshark User's Guide? You can even search for terms like "filter", which might help you narrow down what you're looking for. As @Jasper mentioned, it's not that hard. This is actually something basic enough and applies to any software, not just Wireshark. Learn to help yourself by at least reading the documentation provided. Besides the User's Guide, there is more documentation (man pages, etc) available at: https://www.wireshark.org/docs/. Good luck.
Look into the statistics menu, and check the available options. Hint: a connection is often also called a "flow", "stream" or "conversation". With these you should be able to find the solutions you need.
