TCP/IP Protocol Analysis had tricky packet-level problems where you had to calculate sequence and acknowledgment numbers, spot retransmissions and understand window scaling, and I passed by practicing many TCP stream dissections. Learn to follow TCP streams, use expert information and master the math behind sequence numbers, dup ACKs and retransmits so you can justify each diagnosis.
