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.
