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.
Thanks for the link. Now if only I could figure out why two computers on our Ethernet network have pings that differ by 2,000.
Or, go to Spotlight and type “Wireless Diagnostics”. Spotlight found it by the time I got to “Wirel”.
