1. know your ports.
2. know all you can about SOHO's.
3. know your protocols.
4. know your command line tools like the back of your hand ie : netstat -r and how to add routes (this add a default gateway: route add -r 0.0.0.0 mask 0.0.0.0 192.168.104.19)
5. know your wireless 802x numbers by heart.
now much more I can think of the top of my head, if you want good study material find Darril Gibson's Network + app on the Android/Apple Markets.
