Hello, I have had my Imac for about a year and recently I got on the check my email and noticed that i didn't have a internet connection. no networks showed up. I tried restarting it and then noticed that there wasn't the airport icon on the top menu, so i went to the network settings and tried turning it on and saw " no wireless hardware installed. anyone have any clues? also may be a fluke but my Iphone did the same thing earlier and i plugged in my phone to charge it and that's when it started acting up. could it be a virus? thanks for the help.
