Ubuntu: MacBook Pro Retina late-2013 WiFi BC4360 - “FOUND UNSUPPORTED PHY” [duplicate]



Question:

I've just booted Ubuntu 15.10 from USB dongle on my MacBook Pro Retina late-2013 and WiFi networking doesn't work. I can see the following output in DMESG and LSPCI

Furthermore, my mac freezed up after very few time, after opening the top left menu with apps, maybe something related to graphics because previously it got frozen also after trying to change resolution.


Solution:1

It is telling you that b43, ssb and its firmware are incorrect for your device. With a working, reliable internet connection, ideally ethernet, please open a terminal and do:

sudo apt-get install bcmwl-kernel-source  

Next, I recommend that your regulatory domain be set explicitly. Check yours:

sudo iw reg get  

If you get 00, that is a one-size-maybe-fits-all setting. Find yours here: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 Then set it temporarily:

sudo iw reg set IS  

Of course, substitute your country code if not Iceland. Set it permanently:

gksudo gedit /etc/default/crda  

Use nano or kate or leafpad if you don't have the text editor gedit.

Change the last line to read:

REGDOMAIN=IS  

Proofread carefully, save and close the text editor.

Reboot and tell us if the wireless is working correctly.
