How to fix „No WiFi hardware installed“ MacBook Pro 2011 with High Sierra? No hardware issue!!!

Hello Community!


Since I successfully installed Paragon extFS (no error messages etc.), my WiFi is greyed out (No hardware installed) and I cannot activate it in the system preferences.


System: MacBook Pro early 2011 with MacOS Sierra and High Sierra installed. I use High Sierra. With Sierra WiFi works fine.


When I start the Mac while pressing „alt“ I can choose my network and connect to on the Start Volume screen.


When I boot into recovery mode I can connect to WiFi.


Hardware Test: No issues found.


When I login to Guests account (only Safari mode), I can connect to WiFi.


Admin account and user account=No Hardware installed.


What I tried:


  • Removed Paragon extFS with the uninstaller included in the extFS.dmg.
  • Serval Reboots
  • Reset NVRAM
  • Reset PMC
  • Saved and deleted network & WiFi .plist (not fixed my problem)-restored to old ones.
  • Create new user (same issue)


It seems to be 100% a MacOS High Sierra issue.


If it’s not needed I don’t want reinstall the system.


Somebody have an idea how to fix the system or reinitialize the Airport Module?


Thanks!

I found what my problem was, but forgot to leave a reply in this thread.


I installed Continuity Activation Tool years ago (together with a MBP2012 Broadcom WiFi/bluetooth board) to enable hand-off functionality on my 2011 MBP.


Every now and then (happened twice so far) this creates a problem with WiFi.

Disabling Continuity Activation Tool and rebooting brought back WiFi.

Now you can just re-enable Continuity Activation Tool and reboot.

Edit: Today tried the airport module from friends MacBook Pro (same model). Same issue: Bluetooth=yes, WiFi=no


With both (my and friends module) in the network preferences WiFi is set to „off“. I can click on activate but nothing happens.


There must be a solution without clean install MacOS because my system was running well for many years and I only installed and removed Paragon extFS.


I read something about „repair permissions“ with disk utility but this option is since Mojave not available any longer. Somebody knows how to do on High Sierra?


It‘s 100% MacOS High Sierra Problem because Airport Module is working.


Hope some real professional or nerd read this and can help.


thanks again!
