I installed ubuntu 14.04.02 on a new macbook pro 11,5 (15 inch), but wifi doesn't work.
Here are some information about the wifi adapter.
$ lspci -nn | grep 0280

I followed the answers of the following questions, wifi still doesn't work. I tried many times, the final results are the same.
WIfi Issues with Macbook Pro Retina Early 2015 (12,2) on Ubuntu 15.04
How to get Wifi working on Ubuntu 14.04 (Macbook Pro Retina 15 inch - 2014)
I didn't see the chipset id, but I think [14e4:43ba] should be the pid:vid of wifi adapter. I didn't see much discussion about this device. Hope anyone can share your experience of how do you get this work.
Thanks in advanced!
PS: I have a usb to ethernet adapter, I finished apt-get update and upgrade, it doesn't help.
