These labs have given me great insight into why my ISP asks me all those questions I used to think were pointless when I would call and ask why my internet goes out every time it rains:)
Wireshark is one of my new favorite tools/hobbies and I haven't even scratched the surface of it's functionality.
Command prompt is a much more friendly place after learning how to use some powerful utilities like, arp, ipconfig, tracert, ping, netstat, nslookup and having a basic or at least better understanding of the physical and logical has given me a deeper appreciation for all of these things that I used to think either worked or did not work when it was raining.
