WIFI working but the icon reports that it isn't connected on the toolbar.

After installing Mountain Lion...

This is very odd but WIFI is working fine even though the toolbar icon is reporting Alert: No Internet Connection. When you select it, it takes you to the Network Diagnostics, which then run through everything and report that you have a working connection. But the Toolbar continues to report that it does not have a WIFI connection.

This is strange as I am typing and submitting this despite this dubious claim. :-)

Not a major issue, more an annoyance but still very strange. (Oh and turning it off and on again makes no difference).

MacBook Air, OS X Mountain Lion, 2011 model

This makes it a bit clearer that the icon is wrong.

And here is how it is reported on the pull-down menu. You can see that I am strongly connected to the network.

Had no problems with previous versions of Mac OS X

More and more I think this is just a strange display bug rather than actually to do with the hardware, in System Preferences the Network reports:

Post a screen shot of your System Prefs->Network->WiFI here.

Also post the content of these 2 files : ( or upload them somewhere and post a link here)

/Library/Preferences/SystemConfiguration/NetworkInterfaces.plist

/Library/Preferences/SystemConfiguration/preferences.plist

Try deleting these 2 files ( after backing them up) and then reboot your machine and check if the issue still occurs.

Deleting the files worked!

I lost the configurations, and history of preferred networks, but what the ****, at least it works fine now.

Thanks for your help.

I am in the exact same position with my air but I am unfortunate. Instead of it just stating "alert: no internet conn", it actually means it because it doesn't let me get to the Internet whatsoever :( even though I have the same exact icon that you have on the network..it reads "wifi - connected" with the green dot indicating it is fully connected with all bars. I find this very unusual idk what to do. I am posting this through my iPad, which does work with my Internet..

Thanks, this solved my problem as well! In my case it actually wasn't connecting to the internet, and it would only work after I ran a diagnostic every single time I started the computer.
