Wi-Fi interface keeps de-activating itself, then it's impossible to reactivate until restart of Mac

Mac System : OS X El Capitan, 10.11.6


The WI-FI interface of my mac keep de-activating itself. Then it's impossible to reactivate until I restart my computer.

However, when I do, after 20 mins to three hours, it de-activate itself again.

It's very random but completely stops myself from working.



I've already tried different solutions found online :


- I tried to Renew the DNS Bail : nothing changed, still had to restart the mac

- I tried cycling the network by putting this in the terminal (tried it with en0 AND en1) :

networksetup -setairportpower en0 off
networksetup -setairportpower en0 on


- I tried this :

  1. Open the Terminal application (/Applications/Utilities).
  2. Enter the following text (easier to copy and paste): networksetup -setairportpower en0 off; networksetup -setairportpower en0 on
  3. This should cycle the power to your wireless card, and hopefully give it the push it needs to resume normal operation.

- I tried this:

  • Restart your mac.
  • Open "Network Preferences". On the left tab, look for wifi connection (usually named Wi-Fi).
  • Select the wifi connection, and disable that. To disable a connection, choose gear icon below the tab, and choose "Make Service Inactive".
  • After disabled, delete the connection. To delete a connection, choose minus (-) icon below the tab, left of gear icon.
  • Now that the original connection has been deleted, we must create a new wifi connection. Choose plus (+) icon, select "Wi-Fi" as interface, and you can name it anything as you want, it doesn't matter thought.
  • Apply the change. Once again, restart your mac.
  • After system reboot, voila ! your wifi should be working properly by now

NOTHING WORKED


Now when I'm trying to go on Network preferences an error message appears saying : Impossible to charged the network preferences

Have you tried restarting/resetting the router?


What does Wireless Diagnostics show?

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.
