MacBook – New MBP suddenly can’t find any more Wi-Fi networks

macbook prowifi

I've got a 2016 MacBook Pro for about a month now, and everything has worked very smoothly until today.
Suddenly I couldn't detect any Wi-Fi networks in my area anymore. (including neighbour's Wi-Fi, hotspots, etc…).

This is very strange, since all my other devices still have a perfect Wi-Fi connection. I searched solutions on the internet and I've tried many things, but no success.

  • I tried restarting my MBP multiple times
  • Setting up portable hotspot on my phone to see if my MBP would find it. It didn't.
  • Resetting PRAM didn't help.
  • Removing all my default networks didn't do anything.
  • Restarting in Safe Boot was the only thing that did do something. Strangely enough, I was able find all my Wi-Fi networks while I was in Safe Boot, but when I rebooted back to normal, the Wi-Fi was gone once again.

Does somebody have an idea of what might be going on?
Thanks in advance!

UPDATE: After a couple of hours the problem seemed to have solved itself after I restarted once again in safe boot and then restarted back to normal. My Wi-Fi works again (for now) but I'm not sure if it will stay that way. I'll update this again if it would break again.

Did you try to delete those network plist file?

Doing this you "Reset" the Wi-Fi:

  1. Close your Wi-Fi from Macbook
  2. From toolbar select -> Go -> Go To Folder
  3. Paste this address /Library/Preferences/SystemConfiguration/
  4. Locate and delete these files

    • com.apple.airport.preferences.plist

    • com.apple.network.identification.plist

    • com.apple.wifi.message-tracer.plist

    • NetworkInterfaces.plist

    • preferences.plist

  5. Now restart your Macbook

  6. Open your Wi-Fi and test again
