Seeking Advice; I'm Stuck with WIFI Traffic Analysis Content from Course 7 eJPT

Hi,

I watched the 2 videos from course 7 about wifi analysis. The problem is that I am overwhelmed with it as this is new to me. I watched the first video two times but I still do not get why we use a specific filter at the first place. I decided to leave their labs and do them later while continuing the path and starting course 8.

I wanna know what is the objective from these videos, like what amount of skill should I have after doing their labs? also what do you recommend for studying this topic, because I felt that this topic is unique and it needs other methods of studying than others.

Thank you and excuse me if I made it long for you to read.
