Wifi Diagnostics for Free in OSX Lion

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.

However you find and launch it, Wi-Fi Diagnostics gives you four options: Monitor Performance (which shows you signal strength, noise level, transmit power, and data rate); Record Events (which can keep a log of network happenings); Capture Raw Frames (which records everything coming and going on your Mac’s wireless connection); and Turn on Debug Logs.

If you’re at all interested in what’s going on with your Mac’s Wi-Fi connection or your wireless network, Wi-Fi Diagnostics is freely included with your copy of Lion, and you can’t break anything by poking around the app—so enjoy!
