Monitor Wi-Fi with Lion's hidden tool
by Lex Friedman, Macworld.com Sep 5, 2011 6:00 am
Hints reader nathanator11 discovered that Lion includes a handy app that provides all sorts of diagnostic information surrounding your wireless network. Much of the information the software generates gets pretty technical, but even Wi-Fi novices may find some of the details that the utility aggregates useful.
Wi-Fi Diagnostics is tucked away in the /System/Library/CoreServices folder. To get there, I pressed Shift-Command-G in the Finder (the equivalent of going to the Go menu and choosing Go to Folder), and then typed in the /System/Library/CoreServices path and pressed Return. Once in the folder, I found Wi-Fi Diagnostics and double-clicked it. Alternatively, you could launch the Terminal and type open "/System/Library/CoreServices/Wi-Fi Diagnostics.app", and then press Return.
