My yellow line has these occasional drastic dips…which jibes with the problem I was trying to solve, which is that my wifi seems suddenly to turn to mud (usually in the middle of an online game when speed is important). Any hints?

The first time I ran this the “Monitor” Performance screen came up. But not after the first time. And under the View menu it has “Performance” not “Monitor performance” and the Performance window looks different than the screen capture above. Why did this change after the first time running it?
THANKS

For those who still read this article after the release of Mountain Lion, Wi-Fi Diagnostics has changed in Mountain Lion. It’s now just a report generating tool – could not find any option to Monitor Performance as described in the article.

I copied the app from a Mac still running Lion, and copied it to my Utilities folder on my Mountain Lion MBP. Works just fine.

Save the newly copied app in a backup folder for all the apps you collect so you don’t lose it. Or, back up the app into some other folder, such as a backup folder, before running the Mountain Lion install.

Thanks, but I don’t believe this impacts on the country code of the wifi in the iMac. It was actually already set as UK in the language & text settings, but the wifi diagnostics tool tells me the country is FR. Presumably France.

Odd! Seemingly no way to reset either.
