My Wi-Fi is not working.
My Wi-Fi is not working. In which board the problem is located?
Is this a good question?
Might I recommend an SMC and PRAM Reset?
First, do the SMC:
Shutdown your MacBook Air / MacBook Pro.
Connect the power adapter to the Mac.
On the MacBook Air keyboard, hold down the Shift+Control+Option keys and the Power button at the same time.
Here's how to reset your PRAM:
Shut down your machine. Yes, all the way down, not sleep or logging out.
Press the power button and then press command-option-p-r. ...
Hold those keys down until your Mac reboots again and you here the startup chime.
Let go of the keys and let your Mac reboot normally.
