I posted this question over at the Apple Support forums a couple days ago, but I haven't gotten an answer yet so I'll also post it here.
Ever since I bought my 11' mid-2011 MBA I have issues with wifi. When the computer awakens from sleep, wifi gets turned off and can't be activated again. If I reboot, the wifi icon is greyed out and says "Wifi hardware not installed". The only way to fix it is by turning off and then powering on the MBA.
I've tried various fixes to no avail. I took a screen capture of the messages and also saved system reports of the three stages in this issue: wifi ok, wifi can't be activated and wifi not installed.
Can anyone help me?
