Get this book: Practical Packet Analysis. (No, it's not one of mine.) It's about THE best book I've ever read about knowing the details of packets and using Wireshark. It mainly covers wired connections, but does devote a chapter to wireless packet capture, too.
Plus, you can download all the packet captures used in the book, and try all the techniques firsthand.
