Finding the best wi-fi channel using Apple’s Wireless Diagnostics utility

Was trying to do a little tune-up on my wi-fi network, ran across this helpful article. I did not know there was a built-in wi-fi diagnostic tool. To launch it, hold down the option key, click the wi-fi menu bar icon, select the last option, Open Wireless Diagnostics.

The linked article will walk you through the process. Good stuff.
