    Just a heads up, my battery my died on my 2015 15in rMBP and when i plugged it in and turned it on, it stated that there was no wifi hardware installed. Restarted the computer and everything was back up and running. Hope no one else has an Oh WTF moment like i just did lol.

    It's not a common issue but merely indicates the system temporarily had issues detecting your wifi card.

    yes, sometimes it happens with Bluetooth after a new install. usually rebooting it or shutting down or sleeping the machine for a few minutes makes it load the driver properly and it works from then on.

    I've only had it happen to my bluetooth twice and it was right after the install of the last 2-3 developer builds or so.
