Just wondering if anyone has been having this issue and found a workaround: My wifi works consistently both on Ubuntu and Android. Sometimes it also works on OS X, other times it does not - not even after rebooting. No idea what's the problem.

I also have problems with its HDMI output (random pixels being displayed on the external screen). Again, Ubuntu works fine with the same TVs.

At least the wifi issue should have been fixed (but it wasn't) with the latest update:

The problem is most probably that the MacBook is closed while connected to the external display and the antennas aren't transmitting right. Try opening the MacBook and the Wi-Fi problem should be fixed.

  • it shouldn't influence really, as antennas is normally located in the hinge that connects the screen and rest of the body. – Farside Apr 19 '16 at 14:30
  • No the problem is that the case and screen are blocking the signal. I've had this problem myself – Daniele C Apr 19 '16 at 14:38
  • hm, cool, it sounds like some edge case and bad positioning, Daniele.. I intentionally checked on Mac, the signal from this spot is weak (1 bar only), closed lid with external monitor, and open internal display - haven't made any weather, it's still 1 bar shown and you can work. – Farside Apr 19 '16 at 15:04
  • I don't know exactly, but I can tell you for sure that it worked for me – Daniele C Apr 19 '16 at 16:59
