Summary  Effective troubleshooting combines instinct, experience, and structured techniques to identify, locate, and correct network or computer problems.  Documentation is essential in effective troubleshooting, and should contain baseline information about the network.  A large proportion of networking problems relate to physical components.  Many networking problems can be identified with software utilities such as ping, tracert, and netstat.  In a network containing both wired and wireless connections, it is important to isolate the problem to either the wired or wireless network.
