Chosen Solution

I was using my macbook as usual when suddenly it froze. after a force restart it turned back on however the wifi stopped working. when i click on it, it says no hardware found. tried doing a clean install of the os but still no luck, but got worse because there isnt the wifi signal on the status bar. any help pls ?

I had the same issue REPEATEDLY with my 15" early 2011 MBP. I tried all of the software fixes, resetting PRAM, etc. Even had it serviced multiple times by Apple. Didn’t matter what version of OS X I was running, I always ran into the “No Hardware” issue. But I finally found the solution. It’s 100% hardware in mine and many other’s cases. The problem is the wifi/Bluetooth cable. It runs over the disc drive and is prone to failure. Check out http://warrantyvoidifremoved.blogspot.co… for the full fix instructions.

Have you attempted to reset the SMC? That would be the first step. Hold the left control, option, shift key and the power button for about 5 seconds and release. Then try to reboot. Might as well reset the PRAM as well. Hold command, option, P, R on start up until the machine restarts. If that doesnt’ have any affect we’ll have to dig deeper into a potential hardware failure.

Same problem. MBP 2011 15-inch. Turned out to be that flat cable here too. -JM

Another Mac Technician having suffered this same problem a coupla’ years back; Otherwise mint-condition MBP 15" 2012’s WiFi would occasionally work but was essentially useless. If and when it worked at all, WiFi would never stay connected for more than a few minutes… wasted time fooling around with software for a while, then replaced the AirPort / Bluetooth card with a brand-new one… still had exactly the same problem… frustrating!!! Finally replaced the ribbon connector from MLB to Airport Card. WiFi. now. perfect. FWIW, the failed cable showed NO sign of wear or damage & was probably defective the day it was made. I have another 2012 MBP 15" waiting on the bench with the same symptoms except this one doesn’t detect the WIFI at all but does see Bluetooth… will first try a known-good cable this time. now where did I stash that Airport Card that I pulled on that last one… ?

Hi All, some possibility

  1. The Wifi Cable Came Loose
  2. The Wifi Card has failed
  3. The Logic Board section, inductor has blown.
  4. The Cable is faulty.

i did some research, and it said if it was the cable then the webcam wouldnt work. however the webcam works for me so i think its the card. thanks !

Hey Having solved my year long problems on this issue here’s a piece of good advice. Start with gently changing the flat ribbon cable of your’s. First thing first. Always. Change the flat ribbon cable between the Airport / Bluetooth card and the motherboard and see what happens. Best wishes
