Wi-Fi problem "No hardware installed" - MacBook Pro mid 2009, Yosemite

I have a 2015 MacBook Pro and this happens EVERY TIME my computer restarts. I know...use the option+command+power thingy to restart it...that works, but I should not have to do that every time!

So, I just had this happen with my MacBook pro (2015) & OS: El Capitain and called apple support.

Did the update and restarted and then my Wi-Fi stopped working and gave the "Wifi: No hardware installed" error.

Here is what they recommended that worked for me:

1) Shut down all applications (except for Finder - leave this open). To do this press Option + Command + Esc at the same time. Then close all apps.

2) Completely shut down your computer

3) While its off, press all of these at the same time Ctrl+option+shift+power and hold this down for a good 5 seconds. Then release at the same time.

4) power on your device normally using the power button. Hope this helps.

This worked, I've been having a lot of trouble with this problem happening over and over, but until I can get to a genius bar (but my computer is a bit old, it might need hardware updates) this will do for now. Thanks!

I have a Macbook Air mid 2009 version, i’ve tried all the suggestions but the problem still persists. At first when i tried it solved it but just temporarily, tried the second time it occured but failed to restore the service. I decided to shut down the laptop and not to use it for five days . Today when i switched ON the wifi started to work. But later the laptop re-started/re-booted by itself and now it displays the same error messsage. Any advise??

I am having the same issue. If I shut it down for a few days, when I boot up I have WiFi for a few minutes, then it goes back to “no hardware found.” None of the suggested fixes work. I guess I am heading to the Genius Bar.

If you live near an Apple Store, make a Genius Bar appointment to have the computer tested. Supposedly there is no charge for testing. Use 2nd link if not near an Apple Store or aren’t in the US. Hardware Repair - Keeping Confidential Data Safe

Also try turning off Bluetooth.

If your Wi-Fi source is capable of generating a 5 GHz Wi-Fi network, try that to help avoid conflicts with Bluetooth.

Hey, I have the same problem, in the system information, the wifi only shows the software info. How can I do now?

Thank you, problem solved.

This worked for my 2009 Mac on El Capitan.

I just purchase a 2011 Macbook pro 15" that displayed no hardware installed for wifi, nor did it display the hardware in system report. Tried changing to a new hardrive and new download of OS with no results. Just tried the Option - Command - Escape and forced stopped everything but Finder. Put it to sleep from apple menu, woke and chose restart from apple menu. The restart did not complete so pushed power button, heard chime. The first thing the Mac requested was to connect to wifi. So I did!

Thanks. This worked.

I used did the recommended but it didn't work at all I tired couple of times but it doesn't work

What should I do?

Same thing happening to me, tried all of the recommended things on numerous sites. unsure what to do. someone help? on the verge of throwing my laptop out the window

Hold down the option/alt key while clicking on the  menu and run System Information (the first choice down). Does the Wi-Fi show in the report?
