Hi all, I’ve been having issues with my Early 2015 13” MacBook Pro. When I start by system up, WiFi appears to connect to whichever available network, however after a few seconds I get a “USB Devices Disabled” followed by my WiFi completely disabling (note my right USB is now non functional as a result of this, however the left one still works??). Network preferences says WiFi: Off, however when I press “turn WiFi on” nothing happens and it remains off. I took it to a genius bar, the technician there said there was no obvious issue and that it passed the diagnostics test and re-imaged it. He suggested that if it happened again I could replace the AirPort card as this would be simple, and cheaper than Apple doing it. I have replaced the AirPort card with no luck. I am using a USB WiFi receiver as an interim measure, however I would like to fix the issue for the long term as the quality is quite poor. Thanks in advance
The big clue here is the loss of the USB port in addition to your AirPort’s WiFi. Your AirPort board is likely AOK. Instead your I/O board and/or the I/O board cable is in trouble! I would first try reseating the cable to see if that fixes things, If not I would replace it and then replace the I/O board its self.
